SDR Local Dimming further improved. New option to enable or disable power to USB ports when monitor is in standby mode. Addresses the issue of KVM-powered peripherals not able to wake up monitor. Input select menu is now completely accessible and much more responsive in all no-signal input scenarios by tapping up on OSD joystick at any time. Firmware version is now listed in the OSD menu under System->Information-> FW Version. Fixed some additional bugs from previous firmware releases.

The GP27Q is a monitor I've been watching for a while. It has the potential to become a "go to" monitor due to the quantum dot tech on a flat screen and refresh range at a reasonable price. However the issues around the firmware is frustrating. I doubt I am alone with feeling sick and tired of companies taking the mick out of consumers. It's bad enough with likes of giants such as nVidia and MS without having to put up with smaller companies behaving so poorly. "C'mon Cooler Master. You know better, so do better. Become a champion for the consumer".

[@millanferende6723]

I do get their rush with hurrying this firmware out the door so far. The competition is fierce and gamers demanded HDR + VRR. 😊 In my opinion, so long as I can see that the company CARES about it's customers and their products, keeps updating the firmware, then I am all good. (but they need to communicate with their customer serviced team... they have no idea this update is even out yet!) So in other words, if Cooler Master COMMUNICATES what it plans to do and what it is working on, until it is finished, then I will be more reassured in buying this monitor. I can wait a month or two for some minor fixes.

​@@millanferende6723 The GP27Q is a hidden gem that not many gamers know about which I am glad because it means I was able to buy one without being sold out. The latest Firmware v1.3.1 seems to have fixed the majority of issues of this monitor when it was first released.

[@emp1985]

Hi Tim! It would be very interesting to compare the GP27Q with the KTC M27T20, them being the exact same monitor but differing in the panel type (IPS for the CM, HVA for the KTC). I've read that FALD with VA is a much better combo than with IPS. Also, the GP27U and KTC M27P20 Pro are literally the same monitor with same panel it would seem, so I think it would also be interesting to compare and see how each others tuning makes a difference. Sadly, it seems KTC is lagging behind on firmware updates, as they haven't addressed the initial issues with these monitors, but have offered the update this month (March 2023).

Hey Tim. I'm really interested what local dimming in SDR looks like with these mini-led FALD displays. It would be awesome, if you could implement this sort of testing in your upcoming monitor reviews/comparisons. Thanks :)

In this case, it's not great. The gamma goes pretty far out of whack, making mid-tones lose a lot of detail. In my experience, FALD on with contrast taken way down looks OK-ish, but not quite right. SDR content in Windows' HDR mode looks closer to right. Cooler Master does say they're working on improving that in future firmware updates, though.

[@kgsvv1975]

I want to add to the review of this monitor. I tried to setup triple 4k setup, however, only 2 monitors at a time were able to be connected while the 3rd monitor remained off. I checked around forums and found out the display port DSC function did not work properly. So, the monitor can only be used for single display or dual display mode. It is a very pretty monitor, but, the blooming artifacts really hurt my eyes. I tried to adjust settings, but, this was hard to do. I would suggest waiting for another year to see what happens in the OLED market, wait until prices come down , or wait to see if these mini-LED panels improve in their ability to be connected in a myriad of configurations. I did get the gigabyte m28u instead and although it has a softer showing in picture quality, it s 85-90% of the quality of the gp27u at nearly half the price. For this channel, a tutorial on how to tell if monitors can be made in triple monitor setups would be great. More importantly n how to spot these issues ahead of time before buying so we can also save our time, too. Overall, thisis the best channel for monitor reviews.

[@KeksdoseHi8]

VRR via Gsync (haven't tested AMD/Intel) is still broken. Applications like Photoshop or Slack will crash the display output and disconnect the KVM. The KVM on the GP27U is borderline usable, if at all. Whenever the monitor has to adjust to a change in the input signal (screen blanks black for a significant amount of time), the KVM is disconnected from the upstream computer. It sometimes even takes long enough for games to open on the secondary display instead of on the GP27U.

I love and hate my GP27U - love the colour, the contrast , the brightness but HATE the fact I can't select between inputs without getting a black screen (no OSD). Even when it does work the OSD occasionally refused to operate and the only solution is turn the monitor off/on. Probably going to return it as even with 1.2.1 firmware it's just toio flaky for daily use.

[@spreadthehate]

You don't have to reboot the monitor, press CTRL SHIFT WINDOWS B it will reset the drivers. (sometimes you need to do this twice) Way more easy then turning it off and on again. This works 9 out of 10 times, the 10 time only solution is indeed off/on. ALT WINDOWS B is HDR on/off

[@residentCJ]

If you want to see flickering, test AOC FALD Displays. TFT Central also tests PWM Flickering. Nearly all FALD Display have it more or less. Samsung is ok but Coolermaster and AOC alot. Didnt looked up what the 3000 Bucks Viewsonic is doing in the Flickering Department.

[@jonRock]

My Odyssey G7 flickered like crazy in lots of games with Freesync enabled. I'll never use a monitor like that again, so this would be a deal-breaker for me. I returned that G7 and put the money towards an LG C2 42, which was on sale for $800.

[@triptip00]

I was ready to get the 1440p version. I guess i have to wait until it get fixed or another true hdr monitor shows up

[@adeveloper6653]

The search for the perfect monitor continues

[@DiamantisGR]

Please review the AOC 25G3ZM/BK, it is a VA 24.5" monitor. YOU ARE MY ONLY HOPE FOR A GOOD REVIEW! AOC claims fast response times with this one and I wonder if it uses latest gen VA panels with decent response times.

[@leebutler9470]

Tim, when we getting a review of the 34" Odyssey G8 OLED!?

[@RyanJ7]

I was set to get this Monitor but think I'll go for the Neo G7. Doesn't seem to have as many issues.

[@1stRanger]

This is how things are done everywhere now. Products released half baked and best case scenario get fixed along the way. In less ideal scenario they never get fixed.

Hi! Thanks for the video! Will there be a monitor review MSi Optix MAG342CQR?

[@hennwei]

hopefully their monitors get the same love as their mice.. the first MM731 during the initial release was so crap that they had give a massive discount to clear stock even after they had fixed the issues cause no one was buying them. next they released the MM712 which was much bettter but the damage to their reputation had been done.

[@Equatis]

What a bummer. I returned my GP27Q with the idea of buying it in the future when they got it sorted out. Sad to hear it's not better (and even worse).

[@johnboylan3832]

Was it that bad?

[@DeeSnow97]

it sucks so much that this is your only option if you want 4K, high refresh rate, and HDR, but in a screen that's not 42" or larger. not everyone has that kind of desk space

[@InternetEntity]

Hey, the Sony Inzone M9 exists... It costs more, has lesser HDR capabilities, and has a weird stand. But it works out of the box.

[@ployth9000]

pg32uqx is an option but its even slower for gaming they did get a price cut so its about $2399 not worth that price after owning the gp27u I would say if you know about the pg27uq its slower for gaming but it did local dimming and hdr better it only had 384 zones but it still did not have the same issues the gp27u did like black screen issues and the monitor not waking up in safe mode

[@iiiiT2]

Really gotta mention the Neo G7 - got it like 2 weeks ago. If VA and curve aren't a dealbreaker you should keep it at least into consideration :)

[@cogthusiast1150]

Been using the U for months and haven't noticed any flickering.

[@alphacompton]

Good to know they've pushed out an update, disappointing to know the Q model got downgraded. The U sounds like an overall win for the firmware update. Are there any other decent Mini LED monitors in this price range? The other top monitors are Ultrawide or curved screen which feels like a gimmick imo. The LG OLED monitor could be a contender but I'd still prefer non-oled because I use VR heavily with static content for many hours at once.

[@eugkra33]

I thought that maybe this display wasn't available because it was always sold out. Starting to think it's not available because they are trying to fix all the bugs, and are limiting supply.

[@bart9522]

Especially low availability in Europe, which happens to have strong consumer protection laws. 🤔

[@charleyweinhardt]

Tim, I beg you! Become the champion of pc budget gaming by being the person who consistently informs the masses about CUSTOM RESOLUTION! The world of pc gaming at large is ignorant to the fact that they can set up an array of resolutions between 1440p and 4k for example, so they can have the fps as well as the graphics quality settings they want! 1530p 1620p 1710p 1800p 1890p 1980p 2070p...! these resolutions installed in our gpu's resolution options allow for the best gaming experience possible without the unnecessary and often abysmal side effects of upscalers like fsr and dlss. It's an absolute game changer having these and we're talking maybe only 4% of the gaming world knows about it. Because out of the 25 or so people I've brought it up to, 0 have been aware of it! And with '8k' kicking around the gaming world but not taking off CLEARLY there is a serious problem with people having this as a go to, all these 8K videos, choppy as can be , I can't what them as their performance drops into the 40's, all they have to do is do a custom resolution of 3600p and there video will look almost every bit of 8k but flow at 60fps easily. playing FH5 I get 95-105fps with max settings at 4k with my 3080, all i do is drop it to 2016p and I get my 115 desired 'frame-buster' GSYNC fps setting on my 4k 120 tv... flawless, beautiful, the scaler in that game creates nasty artifacts on the road and the DLSS option is a HUGE step back! I just don't understand why I'm the only person I've ever known to see and express this... not sure where I'm suppose to send you a question for videos where you answer comments but I'd love it if you could plug this in. Okay thanks Tim you are the monitor man! I got a MSI Optix MAG274QRF-QD for my mother who has eye issues on sale back when it dropped because of you and it's been a real pleasure for her, she's on it about 16hrs a day lol!

Hi what is the best display configuration for gp27u with hdr on? I notice dark scenes are really dark and I can barely see characters

[@ThunderingRoar]

Could you somehow benchmark the display stream compression image quality? I cant find relevant tests amywhere. I know vesa claims its visually unnoticeable, but I'd like to see if for example 4k 240 over DP1.4 causes any artifacts

[@haewymetal]

[@MeR-md1jq]

Have they released any new updates that fix the local dimming not working in SDR mode?

[@Muninnnr]

I'm currently looking into a monitor upgrade from my current 27" 1440p. Thanks to Monitors Unboxed, the GP27U is now on my list of likely alternatives. I have a question though: is the pixel density of 4k on a 27" unnecessarily high? My 27" 1440p monitor achieves a decent pixel density so I'm wondering how much it would really help to move to 4k. I'm currently torn between the GP27U and a 4K 32" monitor, and it feels like you'd get more use of 4k on a 32" rather than a 27". Thoughts?

[@jzo1414]

Depends on how far you sit away from your screen, just use a retina calculator.

[@Muninnnr]

@@jzo1414 I didn't know retina calculators were a thing. Apparently, a 1440p 27" will look like a retina display at a 31" distance, which coincidentally seems to be how far I usually am away from my monitor. So it seems like my initial suspicion that 4k 27" at my viewing distance might indeed have an unnecessarily high pixel density. Thanks for the input.

[@vigilant_1934]

@@Muninnnr If you go by Apple's Retina calculations they go for 220 PPI so that's 5K at 27" and around 6K at 32" (216 PPI) which they showcase on their Apple Studio Display and Pro Display XDR respectively. I do know that a 27" 4K monitor at 163PPI sits in between what Apple considers ideal for their OS though there are people using the GP27U as a cheaper alternative to the Apple Studio Display and it work for them. If you're using Windows (or Linux) you can scale it to 150%-200% so the icons and text aren't too small. I personally wanted to go with 32" at 4K because of the smallish icons when I had a 27" 1440p monitor but 32" is too big for my space and not good for my eyes with how close I would have to sit (I'm not VESA mounting it to the wall or something).

[@AceTriggerz]

smooth frog is now my favourite thing

[@marsovac]

Does it flicker when moving/switching windows (alt tabbing) in windows? The LG C1 does this when windows are mostly white - not the standard dimming when the full screen is white, but quick flickers a couple of times in one second briefly.

[@genericperson683]

Are these monitors being sold in the US because I cant find these monitors anywhere

[@remedytee]

Not sure whether it's the right channel or post. I was so pleased with my Cooler Master GP27U. It just broke, half of the mini LEDs stopped working all of a sudden (the left half). Pretty painful. Anybody else experienced this? I'll have to return it to have it repaired? Guarantee?

What does the picture look like in SDR? I'm not a fan of 'no detail in shadows' and 'nuked highlights' that HDR causes.

would you recommend this over the lg 27gp950? cuz if i look at reviews this had better response rates and of course pretty good hdr for the pricepoint but in terms of color it seems to perform a bit worse, is this noticable?

[@thevisi0naryy]

If you don’t care about contrast/hdr and want a better out of the box experience the 27gp950 is prob a better bet IMO. People want this mainly because of contrast.

[@sevn7561]

@@thevisi0naryy i do care a bit about contrast since it is what makes colors pop but i also care about color accuracy, i'm planning on getting a hardware calibrator (spyder x). and hdr is a nice to have not a must have.

[@Denigor197]

I would not recommend the 27gp950 because of screen durability. Starting with the 27GN950-B LG screens are not lasting long enough. If you check ebay there are people selling them off cheap with vertical pixel-lines out of action (usually down the right-hand-side). My own GN950-B now has 4 deal pixel lines after 28 months. This also puts me off recommending other manufacturers that use these LG screens like the Phillips 279M1RV. Unless you are happy to write off your heavily used monitor after a couple of years.

[@KeithEngel]

There has been further firmware updates with the latest being released yesterday 9/23/23. Any chance on an updated video? I'm looking at this monitor as an alternative to OLED and cheaper 1440p monitors.

[@alphacompton]

I just bought this monitor and received it yesterday, SDR looks and performs wonderfully but HDR has a lots of problems. Overall the color looks washed out unless I disable local dimming but then there's some extreme backlight bleed or something making everything look weird and brights really bright. What is the ideal setup? Physical and Windows settings? I'm using an RTX 2080 PC, over DP 1.4 cable and nvidia control panel is set to automatic color control (because this looks great in both sdr and hdr on my LG OLED TV) Should I be manually changing my desktop to 10bit mode? or using an HDMI cable to get better results?
