Is my brand new monitor messed up or am I seeing things?

[Octopuss]

I bought a Cooler Master GP27Q monitor about a week ago and I THINK it might have a problem with the screen, but I am extremely unsure whether it isn't just in my head.
When I have a large white area on the screen I feel like the upper half of scren has warmer tint to it while the bottom is more towards the blue/green.
Weirdly, the viewing angles also change very quickly when I am not looking directly at the centre, which seems unusual for an IPS monitor.

I run the monitor in sRGB mode which I calibrated using a colorimeter for 6500K. I tried taking a photo of the screen with my camera but it's almost impossible to capture properly.
Anyway, do you see what I think I am seeing?... I hope my bad luck didn't strike with full force again. I really don't want to send the thing back to CM's warehouse somewhere in Europe, waiting weeks for a warranty check.

EDIT:
See post #7.

Well, it is not in your head, just adjust the picture a little to see it more:



The trouble is, that your screen may be "within specs".

To get a monitor with guaranteed perfect colour uniformity, you have to buy a special very expensive graphic monitor. Other than that it is a lottery of what you get.

There may some picture modes, that make your white more uniform. If your mini led backlight is RGB, the purpose of this monitor is not a graphic work with perfect colour uniformity, but to dispay videos and gameplay. Seems that the RGB mini led background has 4 modules, which are not calibrated perfectly.

Can you see it while using the monitor to diplay a normal content?

I see that you are from Czechia, you should have 14 day period for returning this monitor, I would do that if this monitor bothers you.

Yeah, it’s a uniformity issue. Unfortunately, quite widespread on a lot of non-pro grade IPS panels. It’s actually better nowadays than it used to be - the peak was in the mid 2010s with the first fast IPS panels from AUO. Calibration won’t affect anything since it’s a backlight thing. Whether it not it’s something that can be considered a fault under warranty is a coin toss - I was lucky to return an Asus screen with similar issues way back when, but it depends on the goodwill of the retailer/vendor. So use the 14 days of the no questions asked return policy if you are really bothered.

This is so much of away from acceptable even if it was a 80€ Ali Express Minitor.
i'd return it. And especially for that price...

 

[BoggledBeagle]

I have a budget IPS 60 Hz 4K monitor, which is perfectly uniform, but useless for gameplay, has poor contrast, etc. Even watching videos on it is not very enjoyable thanks to its grey blacks.

@BoggledBeagle
Surprisingly, I find that budget 60Hz ones have usually decent to good uniformity. Guess it’s connected to the fact that it’s essentially solved tech. It’s funny how it’s a horseshoe spectrum of both budget screens and professional models having good uniformity with the high refresh consumer models in the middle being a complete Wild West. That being said, those issues are usually exacerbated by the edge LED backlight - more expensive FALD equipped models tend to fare much better.

 

[Octopuss]

I had an idea. I remembered there was tools section in the Calibrite software, so I took out the i1 Display Pro and did some testing, along with trying different parts of the monitor in the calibration process itself.
What do you think? The numbers look horrendous to me.

 

[Onasi]

It's not great, yeah. I have seen worse, but that left upper corner is yikes. The second to last picture is even more telling - not just the brightness is effed up, but the color temp is varying too much. I really would consider a return, might want to print out these results to present to the retailer just in case they DO get uppity.

 

[Octopuss]

It's the colour temperature that's the primary problem for me, I just included screenshots from the uniformity check.
Actually let me see the other two I didn't bother with because I don't understand what the delta 2000 blabla something meant.

Remeasured again for a good measure. Hah.

My monitor is Dell P3222QE, I am not sure what exact kind of backlight it has but the image quality and uniformity seem almost perfect to me (both brightness and colour), I never owned so good monitor. But it has its limits. That is why I have 27 inch 240Hz PVA monitor next to it, which is good for videos and gaming.

I am not sure if there is a monitor perfect for everything on the market today.

Do you see that change as you move your head and change your viewing angle?

 

[Octopuss]

Do you see that change as you move your head and change your viewing angle?

I am not entirely sure. I do feel _something_ changes when I move up or down, but an IPS panel should have pretty wide viewing angles, shouldn't it?
I don't think it's the colour tint that changes though.

 

[AusWolf]

Horizontal, yes, but vertical... I'm not sure.

 

[Macro Device]

How lucky I am to be partially colour blind. Can tell red from green but can't tell borked red from normal red so using 95% monitors is fine by me.

Get to the seller, explain your sitch, get a replacement display. Might have much better luck with a replacement unit.

Also, Windows 7... seriously m8?

 

[Octopuss]

I have already requested a return. I'm just going to send it straight back.
At this point I'm just considering whether to play lottery and order a new one, perhaps receiving a good one for a change...


P.S. What Windows 7?

Why don't you go into the Display portion of AMD Software and adjust the screen to your liking? It includes Hue and Color Temp. Just has to be enabled and you get access to the sliders.

I don't even...

Ah, that's a skin, not a real W7.

You can’t fix poor uniformity via software. It applies a filter to the whole screen. You cannot make individual sectors brighter or dimmer or control their color temperature. If the screen has noticeably poor uniformity the only recourse is to exchange it. Full stop.

What skin? I don't understand what are you talking about, lol.

It is also a matter of personal sensitivity. My monitor has some ugly blacklight bleed, but it's only visible on a full black image. It doesn't bother me when I'm doing things on it.

I get that but you mentioned Color temp. I was just making a suggestion that gave you access to that.

The photo of your display in the OP. It has the Windows 7 styled task panel. I initially thought it's a real W7 because just woke up and kinda unfocused.

 

[Onasi]

@AusWolf
That, and room lighting. Pretty much every edge lit IPS will have at least some backlight bleed. A lot of it will be unnoticeable even on a black image in a brightly lit room. But there are some horrendous examples.

@kapone32
It’s not color temp by itself necessarily, it’s the wide variance between zones of the screen. He already has a colorimeter and a calibration software, it’s already superior to AMD software solution for setting it to whatever one wants. The problem is that it’s irrelevant when the edges are showing up to 500K variation to the center, not to mention luminance and gamma discrepancies.

Oh. That's a default Windows 10 taskbar Perhaps it looked weird in the crappy photo.
