Windows 10: Custom resolution Utility

So my setup is like this.

3090 XC3 running an hdmi 2.1 cable to an LGCX 65" on HDMI port 1. I''m using PC mode for the port, RGB 4:4:4 10bit Full 4K 120hz.

Then I have a Samsung Q900T 7.1.2 surround soundbar running a 2.1 hdmi cable to HDMI port 2.

So everything was running great, the sound was fantastic, screen looked amazing, but I was wondering why my audio was only sending 2 channels, I looked it up and found out about CRU, I installed it and set the audio channels to 8 and the 2.1 bandwidth to 48gbps, which allowed for 12 bit color and to send 7.1 through on sound.

It made it so Instant Game Response doesn't trigger, HDR is gone, colors on the screen are out of whack and washed out, checked the chroma test for text and its not doing 10 bit properly, and the audio just sounds terrible now, its like the soundbar is only outputting far away noises, hearing dialogue is almost impossible now.

This is on the PC and on the smartTV apps so independent of the PC as well.

I went to the CRU utility and hit delete to get rid of the profiles, reset everything to normal. The problem persists.

I tried the reset all exe as well and there's no change, my soundbar and TV are essentially bricked now, I didnt know that CRU could actually mess with the firmware inside the TV and soundbar, I thought it just changed the way HDMI communicated with the devices.

This really sucks, this was a pretty expensive setup and its basically ruined now over a single use of this application.

I'm just wondering if anyone has any advice on how I might be able to fix this.

Create a custom resolution on Windows 10

In Windows 10, go to Settings (Win+I) > System > Display > Scale and layout > Resolution. There is some list of resolution.





To find more resolution setting, Scroll down, click on Display adapter Properties. You can see this window (this may vary if your display driver is different).





From there select List All Modes. There you can find many other Resolution options.





There is also a 3rd party software to make custom Resolution setting:: MonitorTests:Custom Resolution Utility (CRU)
