RE: Custom Resolution Utility (CRU)
Hi, after some more tests I have found that the
LG EG920V 4k OLED can run up to max 77hz on 1080p & max 31hz on 2160p with my old non HDMI 2.0 capable Radeon 6970 with CRU. I remember trying to find this exact info before i bought the display but i found nothing online, i hope it help someone because the 77hz is much nicer than plain old 60hz I have one irritating bug though that i had since before i tried CRU. When i turn off the screen so the card dosen't have connection with the screen it thinks it is connected to an lower resolution screen like 1024x768 or something like that. Windows makes that disconnected hardware sound and when it starts up again it often (always?) have my windows and icons moved to the smaller resolution. It also happens when i switch hz. Like from 1080p 60hz to 77hz i see a quick image of the lower resolution and then it switches to the correct one. When i restart the driver with restart.exe it also happens. I had hoped that by removing all of those lower resolutions from CRU and in the custom extension i could fix that buy no unfortunately that didn't work. The strange thing is i got 19 different resolutions below 1080p in windows and several more above before 2160p......why? Can i remove them somewhere? And if i can't remove them somehow or fix this bug, is there someway to auto restore my screens windows & icons when the graphic card losses the connection with the screen? Like some program that fixes that, i know i have seen something about that but it was years ago and i didn't have that issue then. It is like if you pull out the HDMI cable to the card it shrinks all your windows and scrambles your icons. Another question, is there someway to "unlock" the 4:2:0 2160p 60hz resolutions with my card, i know the screen can take it because it is there in the custom extension but i don't know how and if it is possible to activate from the PC. I think Nvidia added support for 4:2:0 right? but does AMD? I have seen some notices on that AMD may support it but how? Is it an option in the newer crimson driver for example? And is there anything i can do in CRU to activate it? Like that surprising unlocking of 2160p 24hz-30hz i did by removing all the standard resolutions in CRU. |
