If you don't have a recovery drive, press and hold the power button to shut off the computer while Windows is booting. Doing this twice should give you recovery options that you can use to get into safe mode: Troubleshoot > Advanced options > Startup Settings > Restart

Hi Toasty. Having an issue with an RX 6600 XT and an RCA 65 inch curved UHD tv and higher resolutions. Before I found out about CRU, anytime I plugged my PC into said tv, the radeon driver would crash with windows saying the resolution of 720x480 was recommended.
Using CRU, I have stopped the driver from crashing, but only at 1920x1080 as I cannot seem to set any other resolution above that using CRU. I have tried various settings with no luck. If I set it to 2560x1440 and restart, it just doesn't set it and stays at 1920x1080. I am using an ultra hispeed HDMI cable from the pc to the tv. If I try to set one using the Radeon settings, it says that res is not compatible with the tv.
Link to TV : https://rca-televisions.com/product/rtuc6520
Any ideas or thoughts? The res for the tv is supposed to go to RESOLUTION: 3840 X 2160.
Any help would be appreciated.

I don't understand what you're doing. The driver should not crash when you plug in the TV. Something is seriously wrong. How did you stop the driver from crashing with CRU? You should not have to add any resolutions. The TV should already define the correct resolutions. Trying to add resolutions that should already exist will not work without solving the actual problem first. What does CRU show by default?

Before I found out about cru, whenever I plugged into the tv using hdmi, as soon as I plugged in, the Radeon driver would crash and the ms basic video driver would load. Windows would then say in display settings that 720x480 was the recommended res.
Using cru, I set 1920x1080 using the automatic hdtv settings and it worked. But still, for the life of me, cannot find out why there's no higher resolutions.
Which cru setting are you referring to?

FTR, I do know that it should just work, I have no idea why it's not or if there's a setting somewhere that was missed etc. If I go into the radeon settings to try and set a custom res, it says the settings are not compatible with this display.

The part about pixel clock limts in the first post explains why you aren't able to get higher resolutions. The EDID only has an HDMI data block with the max TMDS clock set to 225 MHz, so the driver ignores anything above that.

The manual says the TV has an option in the Setup menu called "EDID Switch" with two options: EDID 1.4 and EDID 2.0. They actually mean HDMI 1.4 and HDMI 2.0. Try setting that to 2.0 and see if that solves the problem.

I have tried EDID 2.0 before with no luck.
Ran that patch, was able to set 1920x1440. Then tried 2560x1440 with no luck.
