RE: Custom Resolution Utility (CRU)
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. |
