[SOLVED] 4k TV does 4096x2160@60Hz but not 3840x2160

I am trying to use my TV (TCL 50S423CA) at 3840x2160@60Hz with my rx 6650xt over HDMI. In KDE Plamsa (Wayland), I am able to set the TV to 4096x2160@60Hz through the System Settings, however, if I try to set it to 3840x2160@60Hz, it just switches back to what it was before. The same thing happends if I set to 3840x2160@30Hz before switching to 60Hz. On the first boot, the tv was displaying at 3840x2160@60Hz, however, when I changed the resolution, the issue of not being able to switch back to 3840x2160@60Hz appeared.

I have tried creating a new modeline but it does not seem to work.

You're not gonna be able to add a mode via xrandr on a wayland session.
What modes does the edid announce? You'll likely have to fix/replace that.
Do you have the same problem on an X11 session?

On X11 and I create the same modeline I get this:

xrandr: Configure crtc 0 failed

xrandr gives me this (the last one is this mode I created):

Re: [SOLVED] 4k TV does 4096x2160@60Hz but not 3840x2160

No sudo, but edid-decode (which unfortunately is in limbo between AUR and entering v4l-utils)

for OUT in /sys/class/drm/card*; do echo $OUT; edid-decode $OUT/edid; echo "================="; done

You're presently offered  3840x2160 @30Hz and are trying to add a 60Hz mode in the naive cvt configuration that gets you > 600MHz
You could try either of

◉ cvt12 3840 2160 60 -r
# 3840x2160 @ 60.000 Hz Reduced Blank (CVT) field rate 59.997 Hz; hsync: 133.312 kHz; pclk: 533.25 MHz
Modeline "3840x2160_60.00_rb1"  533.25  3840 3888 3920 4000  2160 2163 2168 2222 +hsync -vsync
                
◉ cvt12 3840 2160 60 -b
# 3840x2160 @ 60.000 Hz Reduced Blank (CVT) field rate 60.000 Hz; hsync: 133.320 kHz; pclk: 522.61 MHz
Modeline "3840x2160_60.00_rb2"  522.61  3840 3848 3880 3920  2160 2208 2216 2222 +hsync -vsync

I am able to set the TV to 4096x2160@60Hz

Are you sure about that? Because the mode isn't in that list…
Do you have HDMI 2.0 or 2.1 and at least a "Premium high speed" cable?
(and yes, that's the official cable grading)

Re: [SOLVED] 4k TV does 4096x2160@60Hz but not 3840x2160

The cable is an AmazonBasics High Speed HDMI Cable with Ethernet, however I am able to use it to do 3840x2160@60Hz on my laptop that also uses arch.
The 4096x2160@60Hz is avaible and works on Wayland, but does not show up in X11.
The modeline with -r works fine, so thank you for that. However the -b modeline gives me no video output.

Re: [SOLVED] 4k TV does 4096x2160@60Hz but not 3840x2160

The modeline with -r works fine, so thank you for that. However the -b modeline gives me no video output.

That's ok, the output can handle cvt 1.0, but not 1.2 reduced blanking and that's probably better than

  YCbCr 4:2:0 Video Data Block:
    VIC  97:  3840x2160   60.000000 Hz  16:9    135.000 kHz    594.000000 MHz

the offered YUV420 mode.
If you still want to try that, please post the output of

xrandr --verbose

Edit: otherwise and please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
