Custom Resolution Utility (CRU)

[littledots]

hiya i wanted to ask for help
i have windows 10 pc with sapphire dual-x r9 270x 2gb oc(radeon 17.1.1) and a 4k tv with native 3840x2160p 60hz on its first hdmi port (RLDED4243-UHD by rca)
but i think the graphics card/firmware is bottlenecking the refresh rate at 30hz;(assuming its not my cables) i know theres a alot of other things possible responsible aside from the gpu but im really high and its hard to concentrate so i decided to post here and ask about helps, i have a dvi-i to hdmi connector too if that changes anything, but i guess my main goals is wondering if i can overclock the gpus refresh rates with your epic utility to see if itll pass through my cables , or if theres a way to comprimise to something that looks like tht resolution through anorhhrhww werk aronud fuck i cant type right now derrrp >:u im sorry i suck, please help me ? -jaime

The R9 270X does not have HDMI 2.0, but it might be possible to get 60 Hz with YCbCr 4:2:0. Does the extension block have a "4:2:0 resolutions" or "4:2:0 capability map" data block? If not, add a "TV resolutions" data block, check "4:2:0 resolutions", and add 3840x2160 @ 60 Hz.

I've used CRU for the past few weeks now and I've noticed that ever since I've used CRU, games that would previously run in Full Screen would no longer work - in terms that most games now basically only run in Fullscreen-Borderless. Any help?

Let me know if you need my PC / Monitor Specs

I can't think of any reason that would happen. The only thing that comes to mind is maybe the game is trying to set a resolution/refresh rate that no longer exists, but most games would just choose a default resolution/refresh rate. What changes did you make with CRU?

here is what my CRU looks like. I believe I only added 3 Detailed Resolutions @ 75hz.

Hey fellas, i have a problem with my CRU

I can successfully overclock my laptops screen 60Hz to 100Hz but for some reason my "bit-depth" goes to 6-bit from 8-bit. And it looks really bad. Is there anyway to fix this? If you guys need anything like my CRU settings, laptop model brand etc... let me know please.

Sounds like a bandwidth limitation. If the laptop panel has a 2-lane eDP interface, it would be limited to 180 MHz pixel clock at 8-bit color and 240 MHz pixel clock at 6-bit color.

Are you sure this is caused by using CRU? How do you know the games are running in borderless instead of exclusive full screen? Does full screen work if you reset everything (run reset-all.exe and reboot)?

Hi there,

This is what CRU shows on my system:



Is this right?

I don't see anything wrong. The other refresh rates should be in the extension block. The lower resolutions are common resolutions that the graphics driver automatically adds as scaled resolutions.
