Hello, @TECHOSAUR ! I want to use QN90D for work at night. Please tell me, what is the minimum screen brightness? Is it comfortable to use in the dark? And is there a PWM on this TV? What is the PWM for minimum and medium brightness?

[@madhaz3359]

Hi great video ( Subbed) I just ordered the Samsung 43 inch , though I can't help notice that in all these clips the C4 looks way sharper in the back ground! Is the C4 sharper? The Samsung looks blurry?

[@oinkoinkmoo]

will be buying the QN90D tomorrow and you helped me decide. Thank you very much

[@TECHOSAUR]

I'm glad to help 🤗

[@kajobecha]

You are my hero, I was looking for this exact comparison! Thank you! !!!

[@mhd9953]

Amazing comparison! I will be going for the QN90D due to the extra brightness, but both look like very nice displays.

[@TECHOSAUR]

yesterday I played Black Myth Wukong for the first time on the QN90D. It was dazzling, even though the game is only in SDR. However, I used RTX HDR and it improved the visuals a bit. Absolutely a good choice

[@Zoux2009]

Extra brightness is always welcome for me 😅

[@direcreep]

today it got a software update from 1200 to 1201, you know where'd i see the changelog ? And What you think about Contrast Enhancer to disabled ? the problem here 12:06 is caused by that being in high

[@TECHOSAUR]

I don't see any change logs anywhere. I also tried to find them but couldn't on both c4 and samsung For me, the contrast enhancer makes the contrast much better. I can't use it without it on, and I prefer it on high, not normal.

[@direcreep]

@@TECHOSAUR I tested it yesterday for a few hours and noticed that the contrast enhancer increases the blooming effect

[@FatalityDiablo]

You are doing the lord's work, sir! After watching this comparison I will definitely buy the 55" c4, mostly because it's also cheaper by 27% here in Poland. Hopefully vrr flicker won't be too bad with freesync enabled :p personally I will nodge the color temp to +1 because the picture seemed a bit too cold on the LG. Cheers

[@TECHOSAUR]

Yes, it is very cold on C4, but I think it might be better if you play with color offsets rather than color temp, I noticed that when I increase it to a slightly warmer setting, it becomes somewhat excessive

[@SrUnr3al]

The QN90 43 line is using a next-gen VA panel, ive tried side-by-side with my IPS 165hz 1ms monitor, and the ghosting is pretty much the same, i saw no signs of black smearing, pretty much the same experience ive had with the Odyssey G6, its a next gen VA.

[@TECHOSAUR]

Weird,i got similar experiences as QN90C 43"

[@danloki78]

Really helpful thanks

I would love to see a ghosting comparison in games like Hades, because of the dash and fast moving camera.

Thank you so much. I'll wait for it before buying.

[@dinartd]

I tried hades on mine. It's present but more subtle, something that I had to look for. In the reference and in my previous monitor (Odyssey G5 34"), the smearing was very noticeable and annoying. If you are from Brazil, this monitor is a no brainer, you can get it for 2900 BRL. There is nothing similar in that price range.

Do you know what the response time of the QN90D is with gaming mode on? and from your personal experience how responsive did it feel compared to the other TV? great comparison!!!

[@TECHOSAUR]

I think in game mode, it would be 4-5 ms. VA panels are not the best in response time, which is why we are getting a bit of motion blur on it, even with game mode OLED are way faster

[@rankcolour8780]

Around 5-9ms depending on your platform and output.

[@Happy-f6x2p]

Which one do you prefer for console gaming between the two?

[@barryjones2366]

Any chance you could do another comparison video but this time with accurate settings using the built-in apps with real SDR/HDR content? And is it possible for gaming to use accurate settings on the QN90D like Contrast Enhancer Off, Game HDR Basic and HDMI Black Level Auto? Surprised you had to use HDMI Black Level Low. I find if I use HDMI BL Low on my 43" QN90B on the desktop I get deeper blacks but then the colours seem worse for web pages, etc.... If you don't use Contrast Enhancer you shouldn't have to use HDMI Level Low or Shadow Detail -5, since CE really lifts APL and highlight brightness. Something doesn't sound right. 😄

[@TECHOSAUR]

Trust me, you’ve seen it for yourself. Setting the HDMI black level to low is my best change. I can’t live without it now. I see all the details, and it gives me a truly elevated viewing image. And as I said, when I set it to normal, it gets a dark gray treatment on top even in places with supposed total black. You saw I had the contrast enhancer on and the shadow detail at -5. Still, if my HDMI black level is normal, it will look bad. Shadow detail comes as a secondary change. My primary setting is the HDMI black level to low along with contrast enhancer and local dimming and dynamic black equalizer to 1 I don’t know if your QN90B is any different, as I’ve never had it. I had the QN90C, and I never set the HDMI black level to low. This may have to do with the QN90D in particular. I will try my best to make the topic you ask for in a coming video. Thanks for your input

[@barryjones2366]

@@TECHOSAUR Thanks for getting back to me. That's good to know that the QN90C doesn't need the HDMI BL Low tweak, it's only needed on the D. Hope you can make it happen soon, thanks!

[@manriprinze5187]

Spectacular review, I definitely prefer to sacrifice the perfect blacks of the LG to get a brighter SDR in the gaming section... Not to mention that the Samsung has the interpolation for games that works miracles in games at 30 fps on consoles. Thank you very much, I have already made my decision.

[@TECHOSAUR]

Welcome to the team! The QN90D is my personal monitor. I wish Samsung had released a QD-OLED at 42 inches, but the one they released is a WOLED and only available in the US, as far as I know. Still, when it comes to brightness, MiniLED will outperform any competition but please make sure to try my settings for the best image possible. I mean, I know everyone is going to have different taste, but give it a try. I promise it will show some difference. Thanks for tuning in!

[@seanguinn]

Hey brotha appreciate the video. I was looking at the 42inch s90d as well as the QN90 D. Not alot of reviews of the 42inch S90D Oled Any thoughts.

[@TECHOSAUR]

Sadly, we don’t have the SD90 at 42 inches in Europe. I wish I had the chance to try it, but I can’t give you any insight since we don’t have it in the market. The smallest size we have is 48 inches

[@Jay-we5nv]

Same here i can’t see many reviews for the 48 S90D (WOLED) and I’m trying to decide between that & the 50’ QN90D mainly using it for PS5, Switch & movies some help would be appreciated.

[@massimoandreoni2634]

I al looking at them just for gaming; how is their upscaling for 1440 or older 1080 games ? I still use some of them and this is a major point for me

[@TECHOSAUR]

For PC mode, TV upscaling doesn't work on either. They recognize when a PC input is used and doesn't provide any AI upscaling or even any picture enhancement. However, for gaming consoles, it does work. For example, on the Nintendo Switch, playing in 1080p feels upscaled to 4K and doesn't have that blurry look. Also, on media playback via USB or the TV smart dashboard like if u open youtube app etc, video broadcasting via antenna or cable, they delivers such a feature. However, for a PC, it's more reliant on your GPU. So when I switch resolution to 1440p on pc it lose image fidelity like on every other monitor However imo i found qn90d has better updacling Nintendo looks way better on it, image is very clear and defined., it almost make the switch a modern console, I couldn't bear its limited image looking and after QN90D it really changed it for me, even the qn90c of last year wasn't as gold in upscaling But for PC none made ever a change Hope i was able to answer well

[@danloki78]

How's the q90 on ps5 pro

[@TECHOSAUR]

Amazing! I'm using it on a PS5 Pro. It supports all display features, like VRR, ALLM, 4K, 120Hz, and HDR. In terms of picture quality, it looks great to me. I don't decrease the brightness; I keep it at 50, contrast at 50, and I tune the color to 20, using the color booster to balance saturation. I use game mode for picture mode and enable Advanced HDR10+ in game mode settings. It just looks amazing. I have no complaints.

[@Alanzudo435]

Por que você escolheu usar a QN90D como monitor ao invés da OLED c4?

[@TECHOSAUR]

@Alanzudo435 Yes, I use it as a PC monitor, and it's better for me as I don't like the automatic brightness drop on the C4 on static windows. For example, when I video edit or use static windows, it dims a lot, and I just get scared of burn-in in those situations. I prefer the C4 as an entertainment monitor more than for professional use. But the QN90D suffers from worse panel latency as you saw in acrollimg, but usually I don't scroll a lot in my work, and in gaming it doesn't really show that bad effect. I think each one will have it's audience, for me personally I find the QN90D a better option but I admit that the C4 has better color accuracy so for artists It may be better to represent better colors

[@Molly-e5w]

Since you use the QN90D as a monitor, is it significantly better than the QN90C? Would it be worth the upgrade or not? Sorry for English.

[@SrUnr3al]

i´m pretty sure its the same panel from 2022 (qn90b), upgrades only on the processing and software side.

[@JairoPL29]

Qn90c is better in 43 and 50 inches

[@rankcolour8780]

90D seems to have more local dimming zones panel for panel so should have less bloom/haloing and slightly better blacks next to a bright light source.

[@JairoPL29]

@@rankcolour8780 In theory it should be like that, but they included an UltraViewAngle film, which makes it have ultra-wide viewing angles as if it were OLED or IPS, at the cost of having blooming in almost all dark scenes.

I want to set the contrast to zero, with the lg c3 the brightness is very low, with the qn90d is the brightness still good with my setting ?

With contrast set to zero and contrast enhancer set to off, I think it will be visible, but will lose much brightness and clarity.

[@afano2312]

@ Thank you for your response, I like your channel, especially the one on TVs.

[@kajobecha]

Greetings from Poland! ^_^ Hello, I have 3 questions if I have time! 1. Which TV do you think is better as a computer monitor and why? (Doesn't the LG c4 dim the white pages when displaying browser pages like the LG c2 used to do)? 2. Which TV plays games like Cyberpunk / LeagueofLegends/ The Witcher better? 3. Which TV will show companies like Avatar better and why:? I'm planning to buy it, initially I was in favor of Oled LG, but I'm afraid that if I use it 10 hours a day, the screen will simply burn out after 2-3 years. And currently I'm using a 10-year-old Samsung Led, which is holding up quite well.

[@TECHOSAUR]

Hey my friend in Poland, 1. In my opinion, the QN90D is the better choice, especially if you're worried about burn-in. With the QN90D, there's no risk of burn-in, even if you keep static images on the screen for extended periods. For example, when I do tests and benchmarks for videos, I often have static windows open for hours. When I do video editing, especially in Premiere Pro, the black background with white elements like text or the video playback window can leave faint shadows if left on for a while. While these shadows eventually fade, it's a sign that I'm pushing the OLED of the C4 a bit too much. If you're using your monitor for static applications for long periods, over time it might degrade the OLED. Additionally, the C4, like the C2, has an automatic dimming feature to protect the screen when static content is displayed. It gradually dims over time, which can be distracting when you're working. You might not even notice it immediately, but after a while, the screen gets darker, and it brightens up again when you interact with it. On the other hand, the QN90D's MiniLEDs are incredibly bright, and the brightness remains consistent regardless of static images or apps. There's no auto-dimming or brightness shifting like on the C4. 2. When it comes to gaming, the C4 does have the edge in terms of deep blacks and overall detail. OLED has individual pixel control, which gives it that signature "pop" and a more three-dimensional look, making objects feel more lifelike. Some users even say it provides a more immersive experience That said, the QN90D shines in terms of brightness and vividness, especially with HDR content. For example, in a game like Horizon Forbidden West on ps5, the stars in the night sky on the QN90D are incredibly bright and magical, creating a fantastic HDR experience. The C4, while excellent with dark scenes, doesn't quite match the QN90D in terms of bright highlights like stars. Ultimately, it comes down to personal preference. many consider the C4 better for gaming, others prefer the QN90D. Personally, I lean towards the QN90D because of how stunning the MiniLEDs look, but both are excellent choices depending on what you're after. 3. I’m not sure what you meant by your third question, could you clarify? At the end of the day, both are great options, and it often comes down to the deal you can get. Samsung usually offers better deals and savings, but I’m not sure how it is in Poland. If I had to choose, I'd go with the QN90D, but I totally understand why someone might prefer the C4, it excels in areas like viewing angles, response time, and that immersive 3D feel. Hope this helps you make the best decision for your needs! I'm here whenever u need more info I may soon get the G8 OLED 32" from Samsung, sure a 32" is smaller size but in interested to try QD-OLED for the first time, I was hopping Samsung to release a 42" QD-Oled this year but guess we still need to wait, the 42 OLED they released is not available in the EU and it's using an LG WOLED so it's not their new signature QD-OLED

[@kajobecha]

@@TECHOSAUR Thank you very much! The third question was which TV would show movies like Avatar better and nicer? What elements (like HDR, color depth, color vibrancy, detail) will be better on these models. An additional question: isn't the black in c4 sometimes overwhelming? Like in Cyber ​​Punk, for example? It seems that in 90D, due to this brightening, a bit more detail was visible in the dark background? I have 2 phones, one with an Amoled screen from Samsung and the other P-Oled with a screen from LG. I admit that I am more attracted to a phone with an Oled screen, it is more natural and more detailed, but HDR scenes actually look quite poor and the screen gives the impression of fading colors. that's why sometimes I want to browse the news / tiktok on Samsung I wonder if LG C5 will have MIA. Do you think that MIA would significantly increase the vibrancy of colors and provide the option to make the detail of the background in black more visible in games like Cyber ​​Punk? (In Poland, one portal subtracted c4 points for cutting detail in the darkroom) In general, if we set the HDMI black level to low on a VA matrix in a Samsung, we have a similar effect to an Oled screen, the black is really good (and I have a 10-year-old Samsung TV ) The only problem is that when you set it to low, it cuts out details in dark scenes as if they didn't exist. The lighting effects look amazing, but that's probably because there's less detail on the sides to distract us. The question is whether in c4 it can be somehow compensated in the settings, is there an HDMI black option?

[@kajobecha]

@@TECHOSAUR o and most importantly, is FreeSync in Samsung QN90D also compatible with Nvidia cards?

[@TECHOSAUR]

@@kajobecha it is not certified to be g-sync compatible however, I heard from others that if you enable g-sync in the NVIDIA control panel and limit fps to less than 3 from the max refresh rate, set low latency mode to ultra and enable v-sync in-game those steps enable g-sync on nvidia gpu, what people said that all AMD enabled free sync monitors and TVs could have adaptive sync on nvidia GPU if you do those settings, but some get certificated by Nvidia and become listed as compatible, at least I can tell you that this one isn't G-sync compatible I mean its not listed in the Nvidia list for models, and also when you open control panel and go to g-sync window it doesn't say g-sync compatible but I tried to do those steps I told you about and I actually noticed less tearing with the QN90D by following those steps on RTX 4090

[@kajobecha]

@@TECHOSAUR Thanks ! I will be buying QN92D 43 inches. Today, I was also in stores, especially in the Samsung Center, and the QN certainly did better with the image than the LG oled c3, which was on display in another store. I compared both on the Avatar 4k HDR video. The employee was also very surprised, when I said that I was interested in the LG C4 or as a computer monitor, he was a bit scared and advised against it. He said that sometimes they accept OLEDs under warranty with burn-in... How much does Qn90D cost in your country? (In my country it probably has a slightly different name, because Qn92D) In ​​total, there are 2 LG C4 models available in my country. One with the terminal 45 (this is the more expensive one) and the model with the terminal 41 (the cheaper one) These are the same TVs.

[@viniciusms6636]

I really appreciate the test, but think ghosting/black smearing is more noticeable on fast paced games, like fps or RPGs played with mouse. Thats my main concern about the qn90d.

[@TECHOSAUR]

I don't see ghosting in FPS games. I played Cyberpunk at 144 FPS, Call of Duty, Atomic Heart, Dead Island 2, and the list goes on. I haven't noticed a disturbing experience, and I play them with a mouse; others may notice it but I mainly do it in desktop mode. I don't think I've played HDR better than on it, don't get me wrong, it's not perfect, but in gaming I've no complaints, in desktop yes I would give it a 7/10

[@viniciusms6636]

@@TECHOSAUR Thanks for the answer. I'm searching for an alternative to a multiple monitors setup for mixed use, but mostly for work. Black smearing seems to be very personal.

[@rankcolour8780]

TBh you will get worse ghosting from the upsampling techniques most games use now like FSR or other temporal AA solutions than you get from the panel.

[@haewymetal]

Your bl4ck levels look really off on both displays. Should have provided the lagom bl4ck level test on both displays so we can see whether your displays are accurate or not. Alan Wake 2 is not supposed to be that dark. I think you are just introducing bl4ck crush.

[@TECHOSAUR]

It could be the camera, because in reality, Blacks were not as dark. You know, capturing videos for TVs requires a very good camera to see the true image. Plus, KZbin decoding sometimes reduces image fidelity. But I blame it on myself and camera. I don't have a DSLR yet. I use my S24 Ultra phone. For that one, I used the Galaxy Z Fold 6, but now I changed back to the S24 Ultra because I noticed it took better videos. It has a better sensor. I'm trying to save up to get a proper DSLR. I hope it will be soon, but I noticed that in the footage of Alan Wake 2, Blacks are very weird on both; in reality, it was much clearer. I'm sorry

[@TECHOSAUR]

Thanks for the precious feedback. I'm working toward improving this. Sorry if it wasn't as clear as intended

[@kajobecha]

Okay, I have a few conclusions after a day of setting up the QN90D. 1. HDMI black set to normal is less eye-straining during prolonged use and you can see more details in games. 2. The TV has an unset white balance, without these settings there is a drama. But once it's done correctly, or close to perfection, it's good. (Not perfect, but good) 3. Viewing angles are average, not bad, but my old Samusng with RBG LED technology had better angles. 4. The colors are very vivid, even artificial when the backlight is higher, but it can be adjusted. Overall... After a few hours of struggling with the settings, I can say that it is good, but there are a few small flaws and a few worse things than in my previous Samsung. There are also some strong advantages such as 120/144hz, 4k, greater detail, better colors.

[@kajobecha]

@@Vombora93 I just discovered it today, the situation is as follows: If we want to use a browser on the computer, watch KZbin or a movie... we must have the Nvidia/Radeon panel set so that the image is controlled by the TV. However, if we want to play, the image should be controlled by the graphics card. - Unfortunately, it will have to be moved, why? 1. When browsing websites or watching movies, the image with Nvidia settings does strange things, as if it was trying to improve the movie and sometimes it does something like some strange 3D effect that makes it difficult to use or unnaturally sharpens the colors. However, if we want to play games with TV settings, we have a lot of lighting effects that distract us, while with Nvidia settings it is done so that the gameplay is in the first frame. I'll think if it can be automated somehow, or maybe I'll write to Microsoft.

[@kajobecha]

@@Vombora93 I have the impression that there is a bit of ghosting with Nvidia settings. However, in games it doesn't bother me and you have to look closely to notice it. However, during the movie, when we set it to TV control, I did not notice the ghost effect.
