I can’t get to safe mode because my windows encountered a problem

I got to command prompt, can I use reset/restart from there?

I don't understand what you mean by this. What did you try and what exactly is happening?

Method #3 shows you how to enable safe mode with a command prompt.

I haven't ever done anything like this. You would need a really old driver to use such a card, and that might not coexist with the driver needed to use the newer card.

Hi guys! First off, I'd like to thank the author of the software for taking his time to create and maintain this utility. I'm facing a rather ugly situation with my RX 480 and my 4K Philips monitor - I cannot go past 30hz.

Please note that the exact same hardware configuration (with the same DP cable) used to work 4K 60hz out of the box about 2 years ago. Back then, I switched to Ubuntu, but now I need to use windows again. As a side note, I can get 4K 60hz under ubuntu using kernell 4.14.1 which makes me think it is not a hardware issue.

I installed Windows 8, then the motherboard drivers and AMD drivers. The 60hz mode is not present in the Monitor section. Trying to set a custom resolution - either 60hz or 59hz (or anything past 31hz) using AMD software leads to: https://imgur.com/a/ebusS8z
As a side note, the generic video driver that comes with windows 8 puts my monitor in 64hz by default. Everything falls apart after installing the AMD software.

Upon opening the CRU utility, I get the following: https://imgur.com/a/UQiSUpH
I am not sure what to make of this, since its clear that the 60hz mode is present, but not selectable in Windows.

What I did was: create 2 new detailed resolution using the "Automatic - LCD standard" - one with 59 hz and the other with 60hz, then delete the 2 that were present there -> click the "OK" button -> then use the "restart 64". The result is the same, which makes me think that i might be doing something wrong. https://imgur.com/a/cHX7R0I

I tried contacting AMD and writing on their support forums - they were totally useless as expected. At this point, the only thing I can think of is buying a new video card - i really hope that it doesnt get there.

The basic driver doesn't deal with refresh rates, so it always lists 64 Hz regardless. The monitor is reporting itself as HDMI, so maybe AMD's driver thinks it's a DP-HDMI adapter. Run reset-all.exe and reboot. Then edit the extension block and try deleting the HDMI data block.

Export a file from CRU, any format.

Thanks for the super fast reply.

I deleted the HDMI data block -> click "OK" -> result was the same (30hz) in 4k

Furthermore, deleting the 30hz mode in "detailed res" and adding either 55, 59, 60 -> "ok" -> reset 64 (even reboot) -> resulted in not being able to go past 1920x1080.

My question is: is it possible to use custom resolution with Nvidia sending 4:2:2 10/12bit to the 4K display via HDMI 2.0? No matter what settings in CRU I'm using TV (UEKS7000) always rejects the signal.

Custom resolutions don't have a way to specify a color format. YCbCr formats are normally limited to TV resolutions. If you're trying to add lower resolutions, try GPU scaling.

Thank you for your answer, unfortunately GPU scaling doesn't work with YCbCr 4:2:2 (works fine with 4:2:0 trough). Looks like I'm of of luck then, oh well.

That's because there's a pixel clock limit somewhere. Run reset-all.exe and reboot. Don't change anything. Check the monitor's menu and make sure the DisplayPort version is set to 1.2: https://forums.geforce.com/default/topic...9/#4764339

reset all worked. I checked the monitor and it's running in displayport 1.2. Sadly, the 4K 30hz issue is still present. I tried the same monitor with another system that has a nvidia 1060 - no issues there with 4K 60hz. I feel so sad.
