Re: Any 5700xt users with samsung chg70 monitor !?

danbutcher,

At one point I had such issues.  I reviewed your video.  It appeared you may have been enabling/disabling HDR in windows.  You shouldn't have to do that.  In fact, I would suggest leaving HDR OFF in Windows.  It also appeared you had multiple monitors.  I'm not sure what that setup does for this.

I will say when I first saw this issue, I think the resolution was to disable every overlay you can find.  In fact, be sure to disable AMD's overlays via the device driver settings!!

Another thing you may want to look at is the color settings in the drivers.  Be sure they are set to 10 bit or whatever the option is for your monitor.

It's been a while since I've seen this issue so I'm not sure how I resolved it, but I really think it had something to do with overlays.

I really hope this helps.

Re: Any 5700xt users with samsung chg70 monitor !?

I'm reviewing this thread which I haven't seen in a while.  I was really hoping AMD would resolve these issues by now or at least somehow let us know they are being looked into.  Perhaps update the known issues section of their README file for the next device drivers?  

I really like AMD stuff and prefer to support them (we need competition!!).  But, my support and wallet have their limits.   From what all I can see, Nvidia's cards support ActiveSync/FreeSync on Samsung CHG70 just fine.  If AMD doesn't get some kind of a handle on this, then I'll have to look at NVidia when Ampere comes out instead of the Navi 20 or whatever AMD will have at the time.

Come on AMD, these problems didn't exist on the Vega 64 series!!!  Let's get this stuff going.

Re: Any 5700xt users with samsung chg70 monitor !?

Hi Chris,

i have same issues when i don’t turn it in Windows 10 but game itself does it. Sometimes it starts switching from displayport to displayport hdr all the time. Another time colours in game get so vibrant that in order to play i would have to wear sunglusses. Will try your advice with overlays but still AMD should get this fixed. I always try to support them with my wallet but this time they let me down.

Re: Any 5700xt users with samsung chg70 monitor !?

I echo your thoughts about the drivers.  There are issues and AMD needs to get them resolved.

One exception to this maybe the vibrant colors issue.  Microsoft has issues with HDR and I don't know if/when they will get them resolved, at least in the near future anyway.  The vibrant colors may not be an AMD driver issue.  I could be wrong.

When it comes to the colors, I will repeat what I'm saying about overlays: find them all and disable them all!!!  Don't forget about Windows Game bar: disable it!!

I hear you about the displayport to displayport HDR switching.  I have seen that often.  In fact, I may have it a bit worse than you.  Several times my screen will flat out go black and just stay black forcing me to power off my system.  The good news is I only see this stuff after my monitor has gone to sleep and I try to play a game.  I have gotten to the point if my monitor goes to sleep and I want to play a game, I'll just reboot my system.  I have a fast m.2 system so a reboot takes like 20-25 seconds.  Still, it's a pain and I should not have to do that.  My Vega 64 did not have this problem!  As long as I don't let me system sit and my monitor therefore goes to sleep, I can play games just fine in HDR.

I love AMD right now but they do have some issues with their drivers.  They need to get them fixed.  My wallet can only go so far.  I make a good living and can splurge here and there, but I have my limits.

I hope what I said about helps,

Chris Smith

Still same issue with latest 19.12.1 drivers....

It's all dull colours and not right... Too bad AMD still hasn't figured this out!

Re: Any 5700xt users with samsung chg70 monitor !?

I don't think you were asking me but I thought I would reply/answer this anyway.

If I let my system sit long enough for the monitor to go to sleep (10 minutes my system), then I do get screen flickers.  However, that is on both standard engine as well as ultimate engine.  If I don't let my monitor go to sleep, I will say I don't see flickering in any games although watching YouTube videos in fullscreen sometimes brings up an odd flicker or two.

Regarding the flickering, there maybe a fix coming.  If you looke in the 19.12.1 video drivers released on 12/2/2019 by AMD, the release notes now have a new, known issue in there which says:

- Radeon 5700 series graphics products may intermittently experience loss of display or video signal during gameplay.

The above describes what I'm seeing if I start to play an HDR game after my monitor has gone to sleep.

So, AMD does now recognize there are flickering issues (although they don't mention circumstances or anything).  There is now hope we'll get a fix to this in the future.

The only issue I've seen specifically using Ultimate Engine is after playing an HDR screen and drop back to my desktop, everything looks a bit dark.  I have to enable HDR within Windows and then disable them to get everything looking right again.  Luckily the "fix" for this is quick and easy so I can grin and bear it although this needs to get resolved.

AMD, none of these issues happened for me on the Vega 64!!

Just my random thought(s) and two cents...

"Radeon 5700 series graphics products may intermittently experience loss of display or video signal during gameplay."

This has actually been in the release notes since 19.10.1 drivers, so nothing new in there really.

I'm inclined to think it actually means the cases where while gaming the display just loses signal and only way you can get it back is reboot.

The problem you're having sounds more display or driver not settings the correct display mode when switching to that HDR case (if you can for example Alt+tab out of it, I'm quite sure it's not the loss of display or video signal -problem), happens to me occasionally when starting a game or alt+tabbing a game regardless if it's using HDR-mode or not, but alt+tab always solved that one.

Yeah, you are right about that.  Forgot about that little detail.

Actually, I'm still leaning in the direction of seeing this same issue.  Sometimes the screen goes in and out and I can see the game's menu long enough to exit the game.  Sometimes though, the screen goes total blank.  When the screen goes blank, sometimes I can ALT-Tab and sometimes I can't.  Typically, I can only reboot.  Plus, I am confident I only see this issue after my monitor has gone to sleep.  I can play a game, exit the game and work on the desktop for a bit, then start another game and all is fine.  What I'm seeing, which matches the description in the one line I quoted, only starts when I let the system sit long enough for the monitor to go to sleep.

Since I can't guarantee I can always ALT-Tab out of a game when this mess begins, I have taken to rebooting my system if I want to play if I know the monitor has gone to sleep.  Annoying but it works.

Again, I am only seeing this issue when my monitor goes to sleep after letting my system sit inactive (which is set to 10 minutes on my setup).

I just had a thought; I'm going to play a game without enabling HDR after my monitor wakes up and see if I can still replicate this issue.  I think I have done this already as Gears of War 5 does not have an HDR mode at all (I think) and I still had problems with that.  But, I'll fire up Battlefield 5, disable the HDR, and see what happens.  I'll try to report back what I see.

Thanks,

Chris Smith
