RX570 weird glitch?

[neocon]

I have a RX570 card, which I recently added to an oldish i5 3570k build.

I have noticed some strange graphical effects which don't look right. I haven't changed any default settings and I'm running at 1080p. Can you see from the s/s that there is a kind of snow.

Doom

The snow is more visible at full resolution.

What's the issue here, am I seeing things or is my card defective?

 

[hohum]

Have to be honest, I can't see anything wrong...? Even with your large screenshot all I can see is the GUI and a completely black background. Check your video cable in the first instance perhaps?

I can't see anything either if I'm totally honest.

 

[neocon]

That's interesting as I can't see it on my phone

Cable or monitor must be causing what I'm seeing to happen?!

I think you need to take a picture of what you're seeing on the actual monitor as the screenshots look fine

 

[Zernath]

Sounds like the cable or the monitor, since the screenshots come out clear.

DP or HDMI cable?

 

[Meddling-Monk]

Agreed with others. Looked at the screenshots and in full res, and all I see, is what I expect from the screen. No snowing of any kind. Which like the others have also said, suggests GPU, Cable (DP/HDMI/DVI) or Monitor. With the easiest test being a simple switch of the cables first. GPU because you have the 3570k I believe has internal GPU, so you could test on the motherboard HDMI/DVI port with the cable. And if both of those fail, it's most likely the Monitor then.

I am using HDMI and I have tried swapping out the cable but the issue is still present.

I'll try a different monitor next.

I tried CS:GO and that looks fine, which is confusing.

 

[Zernath]

Looks like the monitor to me.

 

[neocon]

It's doing exactly the same thing on a different monitor/cable.

Maybe it's some software issue ....

 

[Meddling-Monk]

So you've tried the Monitor and Cable swap. So really what you need to do is try out the onboard DVI/HDMI/DP and see if that has the same issue. That will tell you whether it's the GPU or whether it is something else.

Looks like the gamma is set too high to me.

Hmmm, just thought of another possible result and solution since the card is new.

Go into the AMD Drivers, and check the signal (Pixel Format, for Displayers) is using the proper one for your display: eg RGB 4:4:4 PC Standard (Full RGB).

I had a monitor that kept causing the GPU to switch to one of the YCbCr's even with HDMI connections. Something about how the HDMI on the monitor was implemented causing funkiness to the HDMI signal to happen. It might impact on what you're seeing, so check that out too.
