Cooler Master Tempest GP27Q

Which gpu HUB used to test HDR with Freesync?

Doesn't seem like they say. I doubt the flickering would be a result of the GPU tested, though.

Well, this is their first review using this kind of testing. Some comparisons may happen once they have more data to compare results to.

Incidentally, the 0 - 51 and 51 - 0 results seem broken. They get scored at 0 for every category in every mode, which doesn't make sense since if the response time was truly 0, then the "visual response rating" would be 100.

Overall though, I'm very happy that TPU is now doing proper response time testing in their reviews. More outlets need to do this because so many manufacturers outright lie about the response times in their monitors. The "Visual response time" metric seems a little odd but maybe I'll get used to it.

still, they'd know if they're good/bad/terrible

Freesync support is really flickery on many displays with Nvidia GPU's, when i've looked into it AMD users have less issues

Certified compatible displays eventually get driver fixes from nvidia, unofficially compatible ones get left to rot

Oh, interesting. Well, if Microcenter gets in any of these monitors I guess I'll take one for the team and report if it flickers on AMD. Thank god for painless returns.

The last time he said anything about it, Tim said they do all of their monitor testing with an AMD GPU (a 6800 XT I think?)

I have this monitor connected to a RX 7900 XTX. I would say it is flicker free in SDR mode. When you enable Local Dimming there is some flickering but I rarely notice it, especially not while gaming. Motion Blur Reduction adds more flicker but I think this is normal as it inserts black frames between the images and I feel like it is not needed on this monitor.

That's also what display ninja found in their review: https://www.displayninja.com/cooler-master-tempest-gp27q-review/

But flickering is highly subjective, so I think trying it out yourself is the right way.

576 dimming zone, too low for me and I guess it's the reason why local dimming is off by default, but the price is very interesting.

Unless a 2000+ local dimming zones 27" mini-led is announced, I will purchase an OLED for my next monitor, waiting for CES to choose which one ! ultra wide is really not my priority

You're gunna need all new technology for that, these dimming zones require smaller LED's and the tech doesnt exist for that in such small displays

Small OLED's have brightness issues, instead

 

[konga]

You can totally do 2k dimming zones in a 27" panel. The Macbook Pro has 2500 dimming zones in a 16" laptop panel (they advertise 10,000 LEDs, but those are 2x2 per zone). That's over triple the zone density of what 2k zones at 27" would be.

Increasing zone density has diminishing returns though and fails to solve the biggest downsides of mini-LED. High-detail/high-contrast elements like text and ui elements, or starry skies, fireworks, etc, in media content, are gonna be almost at bad at 10k zones as they are at 1k zones. The only way to make those look good is with per-pixel dimming.

Unless you're a creative professional with an established end-to-end 10-bit color workflow, you shouldn't lose sleep over the 8-bit+FRC nature of this monitor.

When you have a proper HDR monitor, 8-bit+FRC matters. All because your eyes can't see the difference doesn't mean everyone else can't. You don't even need to be a "creative professional". Watching HDR videos regularly is all you need. There is a reason why every HTPC guide out there tells you that 8-bit+FRC is rubbish when consuming HDR content.

Higher contrast panels will help with that a lot (like the new LG IPS Black and similar from BOE/AUO that are yet only on very select products). In static content there's always some caveats but dinamic with proper control even the Sony Inzone M9 with just 96 measly zones already does wonders (ofc no miracles though).

Pixel peepers will always find defects/artifacts but I believe once 1000+ zones (with good control algorithms i.e. like Sony displays) in panels with 2000:1 or more contrast (as opposed to the common 1000:1 currently) it will be plenty good enough for most casual/consumer applications.

Hi ! How can I buy the Cooler Master Tempest GP27Q in France please ? Thank you very much.

By waiting for somewhere that sells it in france to offer it for sale

I think in most parts of Europe, Alternate is their official retailer.

Alternate.fr has it listed but it is out of stock at the moment: https://www.alternate.fr/Cooler-Master/GP27-FQS-Moniteur-gaming/html/product/1842940

You may also buy it from Alternate.de (I bought it there), they do ship to other countries as well, but it is also out of stock at the moment. They do have one in stock with a single pixel error which might be interesting for you: https://www-alternate-de.translate...._sl=de&_x_tr_tl=fr&_x_tr_hl=de&_x_tr_pto=wapp

 

[Victor94]

Thank you very much !

I only have experience with SDR monitors, and all this new HDR stuff confuses the hell out of me.
This looks like one of the very few monitors that has working sRGB emulation mode you can actually customize and calibrate.

What I'm confused about is can you calibrate the HDR mode, and can you have calibration profile for both?

While having a built-in sRGB emulation mode that is configurable is really nice to have in a monitor, these days it's not a hard requirement. We have ways to do something similar on a driver level with any monitor. This article explains things pretty well. AMD has a driver option to clamp your gamut to sRGB, and there's a very lightweight tool that does the same for Nvidia users (with more features than what AMD offers, like greyscale calibration).

HDR calibration however is very tricky. I haven't found a way to do it to a satisfactory level (at least, not with freeware tools). You kind of just have to find a monitor with good out-of-the-box accuracy in HDR mode. TFT Central, Monitors Unboxed, and RTINGS show HDR accuracy in their reviews.

 

[Octopuss]

Is doing this on software level reliable though? I'd need to calibrate it either way, because I sometimes edit photos.
Oh, and calibration really only means using a special device, there's no such thing as freeware tools. I have this Xrite i1 Display Pro device, and using one of such things really is the only real calibration in my eyes.

 

[konga]

I have an i1 Display Pro as well. There's freeware calibration software that uses colorimeters like that. The main one everyone uses is DisplayCAL, but I've found it to be a little buggy, and I've been unable to do a satisfactory HDR calibration with it (though my calibrations in SDR have been pretty good). I have not even bothered using the software included with the colorimeter purchase, I've heard it's not very good.

I wish Calman didn't cost an exorbitant amount of money for home users. That does everything you could want, but there's no affordable home license available.

 

[Octopuss]

I believe this is the (current) official calibration software for the i1 unit and similar ones https://calibrite.com/software-downloads/

 

[trsttte]

Technically speaking all calibration is software level, the difference is said software is running inside the monitor for specialty monitors which makes it a lot easier to use. Monitors that include those options have a steep professional "tax" included even if it's something rather simple to implement

It's nice to have and to be able to improve things but I think if you require precise calibration you shouldn't be looking at Cooler Masters or gaming monitors in general

 

[Octopuss]

I would say brand or use case doesn't matter as long as the panel is not a TN type.

HDR is basically a confusing mess because HDMI was poop.

HDR changes your colour mode to 12 bit, but then has to drop from 4:4:4 to 4:2:0
So to get more colour depth, you lose quality.

Same goes for high refresh rates - my 165Hz displays drop to 144Hz on HDMI, then 120Hz if you use HDR (while DP can handle 10 bit 165Hz easily)


I'd also avoid VA monitors if you go above 60Hz - I was fine with them for many many years, but they're now the cheap budget monitor and even 165Hz VA panels can have certain colours smear at extremely slow speeds (even slower than a 60Hz display).

 

[InVasMani]

My panel only seems to do 10-bit 120Hz, but 8-bit 165Hz. Possibly that's due to older GTX980 maybe that's a GPU limitation not sure. The Intel iGPU only seems to do 8-bit unless using Windows auto color management that looks downright awful.

The GTX 980 only supports DisplayPort 1.2, which doesn't have enough bandwidth to utilize 10-bit 165hz.

 

[InVasMani]

On Maxwell supports DP 1.3 and 1.4 via firmware update on ports. It didn't seem to have DP 1.4a though which I think is how you get 10-bit 165Hz if I'm not mistaken.
