Doesn't work on a S95B OLED TV

[tzurtutjuzrtzurtzurtz]

(RTX 4070, Arch Linux. The TV is in Game Mode, connected over a normal HDMI<-->HDMI 48 Gbit HDMI 2.1a cable.)

I have entered 3840, 2160 and 144 into the 3 fields (suggestion: the 3 fields should be auto-filled with the current values). There is no other custom .conf file in /etc/X11/xorg.conf.d/, except the default 00-keyboard.conf.

When I press the Apply Configuration button, I get:
Failed to apply configuration: /tmp/linux_cru_19091/apply_config.sh: mkinitcpio: command not found. I indeed use dracut instead.

But the /etc/X11/xorg.conf.d/10-custom-modes.conf gets created:

Section "Monitor"
    Identifier "HDMI-0"
    Option "PreferredMode" "3840x2160_144"
    Modeline "3840x2160_144" 1251.70 3840 3878 3926 4002 2160 2161 2162 2172 -HSync +VSync
    Option "ExactModeTimingsDVI" "True"
    Option "ModeValidation" "AllowNonEdidModes,NoMaxPClkCheck,NoEdidMaxPClkCheck,NoMaxSizeCheck,NoHorizSyncCheck,NoVertRefreshCheck"
    Option "IgnoreEDID" "True"
EndSection

Section "Screen"
    Identifier "Screen0"
    Device "Device0"
    Monitor "HDMI-0"
    Option "AllowIndirectGLXProtocol" "off"
    Option "TripleBuffer" "on"
EndSection

After restart, when I press the middle button on the TV's remote, it displays 120p, not 144.

Edit: I see that under the Display setting there is a 144 Hz option now, but when I select it, the screen stays black.

I went to tomverbeure.github.io/video_timings_calculator, selected the 4K144 option, scrolled down and copied these into the 10-custom-modes.conf (removed the Modeline that your program generated):

CVT-RB Modeline 	Modeline "3840x2160_143.99" 1332.75 3840 3888 3920 4000 2160 2163 2168 2314 +HSync -VSync
CVT-RBv2 Modeline 	Modeline "3840x2160_144" 1306.206 3840 3848 3880 3920 2160 2300 2308 2314 +HSync -VSync

The screen doesn't to black anymore and when I press the middle button on the TV's remote, instead of 120p, it displays @144Hz now.

PS: changing +HSync -VSync to -HSync +VSync in your program's Modeline doesn't work, so it's the other stuff like pixel_clock.

Hi, i pushed an update that should fix this, can you verify?

[tzurtutjuzrtzurtzurtz]

Nothing happens if I click Get Current Settings or CVT-RB / CVT-RBv2.

PS: I stopped trying to make HDMI VRR work at 144 Hz (according to this it maybe not possible), because even at 120 Hz the image looks somehow worse and less sharp, less "punchy" than the normal non-VRR 120p mode. I can not explain it, as both is 120 Hz. Using LMArena and asking several AI LLMs, they say that I'm not imagining things and that enabling VRR can lead to a worse image quality. Using a search engine confirms this too. Regarding 144 Hz in general, it's definitely noticeable over 120 Hz. (SAMSUNG, when 240 Hz QD-OLED TV?)
