The AMD Driver Thread

I have a C49RG90 and even thought the release notes for 21.2.1 report 'Some Samsung™ CRG9 series displays may experience a black screen when waking from sleep', this isn't mentioned in the release notes for 21.2.2 but it's stil broken :(

So annoying, I'm having to reboot my PC every time it goes into sleep as the monitor doesn't come back on, it's 2021 and this is an issue :(

It should be fixed in 21.2.1 as far as I know. I no longer have my CRG90 so I can' test it locally.

Running 21.2.2, still broken. It wasn't an issue, can't remember the driver it was OK on, very so very frustrating :(

Try the previous driver (21.2.1) as that has the issue listed as fixed.

As a temporary suggestion, you should be able to use Hibernate just fine instead as I was using that when i did have the CRG90 without issue.
 
HEADRAT said:
I actually came from 21.2.1 as it was broken there, I upgraded to 21.2.2 to hope it fixed, so I guess I'll have to try something pre: 21.2.1

I'll try the 'hibernate' trick to see if that works

Did you try a DDU between installs? If it still happens submit a Bug Report via the tool in the software as it should be fixed.
 
HEADRAT said:
I did an uninstall (back to MS VGA driver) rather than DDU so I will also try that, you'd like to think this would be unnecessary now, why can't we just have drivers that uninstall properly and don't require third party apps.

Thanks for the pointers ;)

It is unnecessary these days for the most part with the Factory Reset option built into the driver now to be honest, but just want to make sure the issue definitely still exists and there's nothing else at fault.

Where is this factory reset button? Can't say I've ever come across it but it would good to have as an option if I ever have issues. I can't use DDU in safe mode as my monitor doesn't post afterward, so on the 2 occasions I've had to use it I've opted not to do it safe mode, which is scary given all the warnings / recommendations in that regard.

Okay, does hibernate work?

Can you submit a bug report via Radeon Software? Include your email in the report (DM me it as well) so we can locate the bug submission and include a picture(Bug Report Tool will allow you to attach a picture) showing the monitor firmware installed? You can find this via the monitor OSD, think it's the bottom option.
 
HEADRAT said:
Yeah hibernate seems to work, sent you a DM, I'm pretty sure I logged a bug report on Saturday with my email address.

If you can't find it let me know and I'll sumbit another.

Firmware = m-RJG949CCAA-1001.5

Your monitor appears to be using a old firmware, perhaps the launch Firmware.

1004 is available on the Korean SAmung website. Feeling brave? Samsung 대한민국

Question:

Will AMD fix the 4K hardware acceleration on YouTube, and in general, for its graphics cards?

Is there more detailed information about AMD's Unified Video Decoder and the supported resolutions with codecs?

Link to a thread with reported issues: 4k video in youtube. | Overclockers UK Forums

Depends if the GPU actually supports the VP9 codec. AFAIK support is from Navi 10 onwards.

Can confirm it works fine on 6900 XT, but not on Radeon VII or RX 580 as they lack VP9 support.
