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.

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.

Hi there,

This is what CRU shows on my system:



Is this right?

On NVCP:

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.

I asked because only that 59.950 Hz showed up in Detailed resolutions, and i thought something was wrong.

The other resolutions indeed show up in the Extension block:



Good to know, thanks ToastyX.

Hello, i have a 24V2Q (24V2W1G5) from AOC with a Freesync Range from 48 to 75Hz.

I've tried to lower the bottom limit of the freesync range. But without any success.

Below 46Hz -> black screen in the G-sync Pendulum.

Quite unlucky. Maybe i've done something wrong?

I set up a 1920x1080 detailed resolution with automatic timing LCD standard 59.986Hz

I ran restart64 and restated my laptop but it never showed up in windows resolution options

Two days latter I now have magenta and cyan pixels shading random colors. My laptop is also unresponsive sometimes and has blue screened 3 times.

I removed the detailed resolution ran restart64 and rebooted but its still the same.

Since I never applied the resolution with windows, is this just a coincidence?

If not, what model MacBook do you guys recommend? I set up WinXP with Parallels on a 2013 macbook once and have always wanted one for myself. I'd mainly use it for 2D game development/cross platform test bed.

Even if you were able to add an incompatible resolution, that would not cause blue screens, and artifacts would be noticeable right away, not two days later. This sounds like it might be a faulty GPU and not the screen itself.
