RE: Custom Resolution Utility (CRU)
Hi ToastyX,
I'm trying to use your software with my tv Sony XBR-65x900A that is 4k but doesn't support 4k at 60hz 4:4:4. This is only obtainable using Nvidia chroma subsampling. Also, I'm using 970 GTX video card. What I'm trying to achieve is 2560x1440 - that's not supported by my tv - at 60hz. At 30hz is already on Nvidia Control Panel. When I select 30hz, since my TV doesn't support it, I get 3840x2160 but an upscaled - probably using GPU scalling - resolution. The thing is, nothing over 1080p is in the PC section, everything falls under UHD, HD section. So, even using your software or using Nvidia Custom Resolution, I get a black screen because they try to create a PC resolution, not an HD compilant resolution. My question is, is it possible to manually insert the modeline for 4k resolution or even 2560x1440 that falls under the 10.2gbit of hdmit 1.4? Or anyway force chroma subsampling like nvidia drivers? Hopefully I was able to explain myself on this situation of chroma subsampling  Thank you! |
