Why You Shouldn't Use a 4K TV as a Computer Monitor

[@HelloDavid]

*For anyone who is too lazy to watch the whole video:* - You CAN use a 4K TV as your computer monitor (most people won't even notice the problems) - The main issues to consider are 4:4:4 Chroma Subsampling & Input Lag - Not all TVs have these issues, some are perfectly acceptable as monitors if you don't mind the size - The important point is that you are aware so you can identify and research on your own lol. you people are funny but it's good to try and keep everything honest.

Misleading video title.

[@francoisluneau]

Interesting review, which I found useful. Having just gone through the same analysis after purchasing a Vizio D50u-D1, I would have enjoyed seeing this before my purchase, but I must underline that the 4:2:0 chroma still keeps the full resolution in black and white, so not an issue for reading most text (black on white, or white on black). You lose resolution in the color channels only.

[@fallendaemon]

I'm literally watching your example of input lag and I don't see what you're talking about. I

[@shyguy425]

Input lag is hard to see... it is the delay between you doing something and seeing it.... It is more noticeable when you have the mouse in your hand. I have a gaming desktop and PC's hooked to tv's. There is a very big delay on a tv. Not suitable for high-end gaming.

[@okccardude]

David Zhang You are forgetting one of the biggest reasons why gamers chose a PC monitor over getting a TV, and that is pixel response time. The LG OLED TV's are excellent (0.1-0.3 ms) and some select few LCD's such as the Samsung JU6400 (6.8 ms) are okay here, but... Are you kidding!? The Samsung KU6300 is terrible as a PC monitor for anyone who wants to game! That is because it has a horrible 18.7 ms response time!

Been using TV's as monitors since LCD went mainstream. First TV was a 32" 1080p Insignia with a VGA input in about 2007. The size alone made me never look back to those tiny inferior pc "monitors". Upgraded to a 46" 1080p Insignia in about 2010 with yet another VGA input. Great experience again. Next was a 55" Samsung 4k in 2014, one of the first ones ever out. I was stuck at 30hz until the DP to HDMI 2.0 adapters came out. But I still loved the experience. Next was a 50" Samsung 4k, 4k had matured a bit so the picture was much better, especially the contrast and and blacks. Now on a 55" Samsung 4k Q6F quantum dot TV. Just amazing. Everything I could ever ask for. Amazing color, amazing blacks, amazing motion for watching movies on my PC. Gaming with my 290x is also amazing. Always had 4:4:4 chroma and never had any input lag on any of my TV's except when I was stuck at 30hz waiting for the adapters. Y'all are late to the party!

Just bought a 4K Samsung NU8500 that also does 4:4:4 and can even run at a native 120Hz @ 1440 & 1080p. Has excellent HDR color and great contrast too, but the best part of the TV is the input lag: 15.8ms @ 4K60, and 9.3ms @1440/1080p120! That's as good as any monitor. It even stays under 30ms when using motion interpolation, so you can basically have a smooth 120 FPS in every game, even if your PC struggles to pull that off on its own @ 4K. Hell, it even supports Freesync. All for under $1k for the 55" model (or $850ish if you're willing to buy an unused open box model).

(you gay actually used to the sound though) I use it for rocket league in 4k, so you know I need a good response time, refresh rate and input lag. the thing about this tv though is that you need to be under 60 fps in what ever games you play or it will cause screen tearing. so max out the game graphics to compensate. (you can't go over 60fps anyway since it's 60hz) if you don't game then you should be completely fine.

[@bgates275]

I've been looking into getting a 4k TV for PC gaming. However, I'm not sure whether getting a Sony is a good idea. Every manual that I've looked at for Sony 4k TV's says that it can only do 30 hz at 4k on PC through an HDMI connection. This is disappointing, considering how good the picture quality is on Sony TV's. In addition, I've also heard that input lag is an issue on Sony TV's, which wouldn't bode well for gaming.

[@GmailUnited]

I use a Sony XBR 43 inch 4:4:4 @ 60hz for a monitor. Initially there was input lag but I found a way around it. The trick to getting rid of input lag is to turn off all "TV" enhancements (motion blur, true image, etc...). The important setting to get rid of input lag significantly is to put the TV into "Game Mode". Pray that you have this setting!

[@Continus]

For the input lag (if you notice it), it's probably due to the T.V. automatically setting your frame rates to 30 fps. This is so video gets a priority so it looks smoother in animation. To somewhat fix this, go to your display settings > Display Adapter Properties > on the top tab click on monitor > and select the refresh rate of 60 and click apply. In some cases (depending on your pc) this will revert to 59 Hertz. Other problems with using a T.V. as a monitor are with games. Some games like to switch to 30 fps automatically because of what your T.V. is reporting to your graphics card. And that is a whole other topic.

[@Cade_Squirrel]

My 4K 43 inch Sony Bravia is my main monitor and is amazing for everything, it can do RGB 8 Bit Full Range HDMI at 4K and every color format imaginable, it has a minute input lag, on par with my IPS monitor running at 60Hz, and thanks to it being 43 inches the pixel density is very high without being crushed, any smaller and the pixels would be entirely indistinguishable, which isn't always a good thing not to mention my TV also does 1080p at 120Hz so I can switch to that if I want high Hz, and running at 1080p also gives more headroom for visuals at that high frame rate, and on top of that my TV can do 1:4 scaling meaning 1080p is perfectly scaled to 4K with no blur, it actually looks better than 1080p on a 1080p panel just because of the insane sharpness given by such a clean upscale, and the color and contrast is just far better on my TV than my monitor, not that either are bad but my TV gives much better contrast and better blacks, despite it only being IPS, it also has HDR support which is nice if I ever want to use it (I don't often) I just can't fault this TV it delivers on everything, it's the best monitor I've ever used and it isn't even a monitor I do kind of wish I could do 1440p 120Hz on my TV like what I did on my monitor but 1080p with downsampling or good AA can look just as good

[@buranainstitute1442]

I use my 24" 1080 TV as a monitor for a long time now. I mostly use it for office work: word documents, excel sheets etc. The text readability is fine. Lately, I tried to upgrade my monitor/TV and connect my PC to 32" 1080 HCL TV. I immediately noticed a problem: the text readability is immensely poor. On 24" screen 1080 pixels were showing fine, but on 32" size, there is obviously less amount of pixels for such size even though it is only 32. I tried to upscale the text size in settings in Windows, but the screen real estate drops dramatically. I cannot properly open two word files side by side and work because the text is too big and uncomfortable. I think the solution is to get at least 2K TV for monitors larger than 27 for better work experience. If you are a gamer, I guess you will experience no problems with monitors larger than 27 on 1080. But for office work and text readability, get 2k or 4K for larger size TVs.

I use a recent 49" 4K LG TV as a computer monitor, and I'm actually pretty happy with it. In high-paced FPS games input lag isn't that noticeable. It supports chroma 4:4:4 at 60Hz.

[@L337g4m3r]

A big thing you need to watch for is most TVs will not display 1:1 pixel mapping by default. They like to slightly scale the image for some dumb reason. This leads to blurry edges. You need to display an appropriate test pattern then go into settings to enable 1:1 pixel mapping. It is called many different things so I can't name the setting. You also need to make sure the TV even has this mode before buying.

I have the KU6300 and clicked on this video thinking "There is nothing wrong with using a 4K TV as a monitor". You made good points throughout and was happy to see you featured the TV I use.

[@tjuggernaut29]

as someone who uses a 4k TV as a monitor, most of what you mentioned is pretty miniscule. the main reason that I think a 4k TV is a bad monitor is that (at least with my TV) the pixels are arranged in a hexoganal/ honey comb layout, rather than in rows. this makes all the sharp borders you are used to seeing on a monitor appear fuzzyer. also sitting only ~20 inches from the screen, the depth difference from the back light to the front panel is very noticibly when looking at an angle toward the corners of the screen. hence why they make curved TV's. however I will likely not ever go back to a standard computer monitor because I have gotten used to how much wonderful screen realestate that a 55inch screen at 4k offers. it is the equivalent of a 4 27inch 1080p monitor setup. being able to have 4 to 6 windows opened at once is a huge productivity booster.

Another thing to consider: In my experience, it seems like TV's have a dark outline or "micro gap" around the pixels, namely because they aren't supposed to be viewed from really close, so as long as they are bright enough, you may not notice a gap between them. But with monitors, no matter the size of the pixels, they always seem to have less of a micro gap between eachother as TV's. This explanation isn't completely debunked by a higher resolutions or lower resolutions. Sadly I don't have a 4k monitor, and 4k TV. But I have a 1080p monitor and a 4k tv for example

Playing games like rocket league at native 4k is something incredible and more considering the color range of this tv with such a colorful game. Something to take in consideration is that my 980ti is working 100% to give me 60fps and in games like fall out 4 it struggle to get 40 - 50 fps. For reading text is just perfect at around 175% dpi scaling. And im using it at 60hz 4.4.4 or i should say RGB with Complete Dynamic range. You should never go for a 4.2.0 TV for monitor.

For games and media, it absolutely blows away the 27-inch 2560x1440 I was using before. However, for general PC use (like text editing, reading and web browsing) I think I still prefer my 27-incher. 40-inch is freaking huge for a desk, and because the screen doesn't fit entirely into my field of view I actually have to move my head around to see things on the screen (which is great for added immersion in games, not so much when I'm trying to use to Chrome with the tab bar at the top or bottom).

Thanks for the video, but Can I still used 4k tv as monitor for music recording studio?

[@AS-bm5xv]

Is there any TV with 4k 120Hz at 4:4:4 and low input lag?

[@togwam]

Ever heard of game mode, it will seriously limit the TV's image processing to where the input lag vastly diminishes.

[@h0uz3t00b]

Recently got a cheap UHD TV to be able to see UHD content at full resolution. For fun I set it up as my main monitor and as you describe, the color representation and delay are bad for general work. So now it's been put to it's intended use as a secondary screen while editing.

[@nunyabusiness896]

Getting a 55" 4K HDTV as a monitor is awesome. Gaming monitors are completely overrated and even 4:2:0 really isn't that big of a deal. The biggest factor is input lag, but my TCL S405 has 15ms input lag, which is up there with some of the best gaming monitors, so it's crisp and fast like a monitor should be. I do notice a slight bit of "rainbowing" in white text, but I remember a lot of computer monitors that had that issue as well and it's very minor and most won't notice. If I set it to 30hz it goes away, but the extra smoothness of 60hz is well worth it. Overall, if you're going to go 4K, it NEEDS to be 50"+ or you aren't getting the full benefit of the extra resolution. 4K does you no good if the pixels are so small you literally can't tell a difference side by side with a 1080p monitor. The extra size and resolution makes seeing online opponents much easier to see in FPS games and makes you feel like you're in the cockpit of a jet or race car when playing flight sims or driving sims respectively. When you can get the TV I bought for less than $400 on Amazon, it's a no brainer.

[@TheHeldgaard]

I don't get how people can use a TV as a monitor. Above 16:9 27" or 21:9 34" just feels to big and bulky on a desk. Also the input lag damn...

[@BW022]

You don't put it on your desk. You put it 4' to 6' away from you on the other side of your den or living room. You then use a wireless mouse and keyboard from across the room. This saves you needing a desk in your room to start with, or is you have a desk connect the PC to a normal monitor (when doing intense desk work) and a large TV for the couch. Input lag... is meaningless for video, productivity (Word, Excel, web surfing, email), and most games. The vast majority of PCs can't run most high frame rate action games at 4K. You are talking high-end dual graphics cards on PCs likely hitting $1500-$2000. At those prices levels... you aren't worried about saving $400 on a TV... you go an buy a $1000 high-end TV or a large monitor with low lag and 4:4:4 colors. However, for the 95% of other folks... you run such games at 1080p and input lag goes away -- same as the millions of Xbox One, PS4, etc. users who have 4K TVs.

Definitely do your research before getting a TV to use as a monitor. In my case, I went with the Samsung QN90A QLED. Looks amazing, has most modern features, and can still do gaming extremely well. 120hz, 4k, hdr, vrr, 3ms response time, 2.5ms input delay. Perfect multi use display.

[@cancercrab6487]

This is the exact tv/monitor I've been looking at. Do you have it on a desk or wall mounted? I want to put the 43" on a desk with me being about 3 feet away min, however I would also like to be able to sit back about 6 or 7 feet away. With your experience with the TV, do you know if it would be suitable for these needs? Tysm

[@InvaderZae.]

@@cancercrab6487 I would say 43" is good. I'm on a 55" and it's a bit too big for being 3 ft away. 6 to 7 feet away is definitely nice for watching movies/shows etc. After these past months of using it pretty much every day, I'm still happy with it. I play a lot of competetive games like League of Legends, Apex Legends etc, and I don't feel like I'm being hindered by response times or anything. It's gysnc capable so the experience is nice and smooth.

More than 32 inches is TV 📺 not a monitor 👎 .My favorite 4:4:4 3840x2160 5ms input lag , IPS PANEL at 24 inches

[@FulciLives]

Do your research. I have a Samsung 40" 4K UHD TV and it supports 4K@60hz with Chroma Sampling at 4:4:4 and the input lag, while higher than a computer monitor, is still very low (around 40ms). Best of all it cost me $300 USD (on sale). Normally this model would be around $450 USD.

[@mc2engineeringprof]

"Why you shouldn't..." (goes on to say that there are plenty of cases where you can and even should) Indeed "game mode" (which actually usually just eliminates different video effects which increase lag) gets most displays into . Indeed, most TV displays that are 4k UHD can be setup for lag the same as monitors, and with some video tweaks on your pc, any text distortion can be essentially eliminated. In short, unless you're doing computer animation or still graphics creation or editing, there's really not a lot to worry about...even with the less expensive displays. If you're really unhappy, up your zoom. You'll still have vastly more real estate than you could in any other non 4k environment.

[@LilyUnicorn]

He lists two cases.... your use of "plenty" is highly erroneous

[@mc2engineeringprof]

@@LilyUnicorn There are only like 4 case examples given. Therefore, I'd say that the TITLE is highly erroneous. Long story short, I rejected his advice. Bought one to use as a display. Works and looks great. No problems at all. Saved a bundle of money. Bad title.

Matt Hungerford used my B7 for console and PC gaming. Never had retention issues.

[@bigdog3628]

As a person who has a big desk, I can put the TV far enough back that there is a good 3-5 feet between me and the tv. make sure the tv supports 4.4.4 chroma, and take in to account input lag. For me personally anything under 30ms is acceptable. Currently I am using an older TCL Roku tv, but am upgrading to a more current version of either 43 or 55" I think I might find 55" to be too big, so I most likely will stick with 43". Another thing to keep in mind, is that if using a 4k TV as a monitor, You will NOT get higher than 60hz at 4k res. You want higher than 60hz and 4k, you have to get a monitor that supports it, as hdmi 2.0 doesnt support 4k @120 hz. Obviously this isn't ideal for "professional gamers" but I dont think those people use higher than 1080p anyways.

[@superboy305]

Yeah I plan on getting the Samsung 6300.

[@GlassTopRX7]

That's what I have you love it once you get over the limitation of the setting when connected to a PC. You can't set gaming mode on the TV unless you are in the game, for most stuff it's fine with out it. The TV wont go in that mode from the desktop so if you want it enable you will have to be full screen in the game.

[@NuclearHendrix]

Set the device type to game console, and you can stay in game mode. The only time it'll revert back to PC mode is when you turn on your PC. For some reason the T.V doesn't save the setting.

[@GlassTopRX7]

Thanks. It resets when the TV goes to sleep and noticed you lose 4:4:4 which I'm betting is why they do it.

[@BoogieDownProduction]

@@NuclearHendrix and @GlasstopRX7 no no no. You want to just keep it on PC mode with the desktop set to 4:4:4 or RGB so you have 1-1 pixel mapping with minimal enhancements. No reason to switch to gaming mode even when gaming.

[@constantinosschinas4503]

thanks. chroma compression is very important. input lag can differ in ports and manufacturers sometimes point the faster one. disabling all tv post processing (hdr, sharpness, frame interpolation) can also reduce lag to acceptable levels.

[@lewisdownes9821]

Definitely a great video overall but as you stated it's not always the case, just anyone who wants to try using a TV as a monitor should definitely do a lot of research on the product first. While the lower price options like some of the Vizio or hisense TV's (and sadly some more expensive ones like LG oleds and their horrendous input lag) are a bad choice for a pc monitor there are a fair few exceptions, my UN65KS8500 Samsung can do 4:4:4 with 60 fps 4k hdr with only 19ms input lag and what is quite honestly the clearest image I have ever seen. Because of the size I obvs don't use it as a computer monitor but they offer very similar options with near the same qualities for smaller screens.

[@HelloDavid]

Thanks! I completely agree. Oh man. My eyes would burn if I used a 65" TV as a monitor. lol

[@HumbertoRamosCosta]

The Samsung model can have a input lag of 20.4 ms without the 4:4:4 chroma, but you will not need to read small text when playing games. When you came back to 'productivity applications' 40 ms is very good and you can have 4:4:4

[@BebxOfficial]

Fix the title, it should be gaming monitor. A TV monitor will still be fine for general use, and especially productivity (High resolution for a cheaper price than a monitor) For games it is bad, but for productivity purposes, 4k resolution will still look better than 1080p, even with some data lost.

[@christianpearson214]

It is true though. Bought a 55 inch 4k Ultra Phillips tv. I primarily game on my desktop, and wanted a bigger screen with better quality, since I previously had just been using a 40 inch 720p tv as a monitor. What I didn't know was that the tv only capped out at 24hz for gaming, and most of my performance pushing games were impossible to play on the tv. It became a living room tv meant strictly for tv only, and I had to settle for a 45 inch 1080p curved Samsung as a monitor instead.

[@lukaschang6973]

The bezel on that TV is bigger than my future.

[@lildebbies3909]

Who cares about a bezel on a tv, it's still 4K

[@WARNING-z7d5k]

my Acer 1080p monitor is designed for gaming and video editing, and it cannot replace my 1080p Samsung Smart TV with my xbox series x for Netflix, Disney Plus, Paramount Plus, and other streaming services. Smart TVs have dedicated built-in apps and a larger screen that is optimized for comfortable viewing of movies and TV shows. Monitors, on the other hand, have better specifications for tasks like gaming and editing, but they do not offer the dedicated streaming experience that Smart TVs provide.

Just discovered you. Great KZbinr.

[@nameinvalid69]

Once you go TV and configure it correctly you'll never go back. Samsung user need to dive into your setting and find "PC mode". Older models may called that option as a very weird name, it's called "Edit Name". That will eliminate any TV post-processing, resolve inaccurate color issue, and visual display that will fit perfectly instead of having weird positioning at the border. AMD driver need to set to RGB mode instead of Ycbcr for to enable "HDMI Black Level" adjustment. Set black level to "low" instead of default, that will eliminate wash out problem. Additional calibration will be needed to prevent the visual getting washed out or what not. Personally using 80 contrast, 50 brightness, 70 sharpness. You don't control display brightness with the "brightness" option, instead you do it with the "backlight" option. I don't go crazy with backlight because that will really hurts your eye and causing nausea in some cases, I use 0 for normal use and up to 4 for media / gaming.

[@clow539]

Yea but wich one? There are tons of diffrent tv's 😕

[@whechi]

solution get a Vizio P Series. I'm running my gaming computer at 4.4.4 chroma at 4k 60hrz (HDMI 2.0 is limited to 4k60hrz). Can also do it 1080p 120hrz (the native refresh rate of the panel) it also has no tuner whatsoever and that's why they can't even market it as a TV legally but rather a "Home Theater Display" and for any of you owners that can't​ get it to work (most of you) you have to enable HDMI Color Subsampling in the input settings on the input you are using on your PC (recommend HDMI 2)

[@whechi]

I also scale everything to 200% and everything is perfectly scaled vs the 150% I would have to do on my 1080p limited to 60hrz because A. my 60hrz panel and B. HDMI 1.4

[@OfTheTimeLords]

Most TVs now offer HDMI 2.0 inputs with 4:4:4 chroma subsampling. Also, input lag is fine for most uses, definitely not that high as it used to be, although you won't do "professional fps tournaments" on this thing. I have a 3 year old Samsung that covers 101% of sRGB (tested using a calibrator) and can get quite a bit low in its blacks. I use it for photo editing and I am very pleased with the results I get. I game occasionally and I tend to also do software development. A 48" 4K display counts like 4x24" 1080p ones arranged in a grid pattern. This is serious real estate! I first became a convert in 2014 (I had to be very very careful because HDMI 2.0 and 4:4:4 chroma was available in very limited models) and I am not going back now. It's so great, that my employer agreed to let me have one in the office.

I think a TV as Second Display for your pc might perfect (when you don't need 2 second screens that are vertical). You can "watch" TV while doing some stuff on the pc. You can use a wireless hdmi (unbox therapy showed a wireless hdmi product that looks great) setup to stream your consoles from the living room into your office. When you need the space, you can still use the TV as second display. I think everyone knows what they need. I play pc games and I think a 144hz monitor is good when you have a good pc that can deliver 144fps. I also need a second screen. At the moment I have an old 4:3 second screen and I need I streaming on twitch, this isn't enough. My graphics card only supports 2 displays, I can't upgrade. In the future when I have the money, I will buy 3-4 monitors. The main monitor must have the best specs. One lazy monitor where I can display stuff that I don't need to look at often and the other 2 monitors (vertical setup) for additional information.
