THIS TV IS SO TRASH, IT CAN'T EVEN DISPLAY SDR REDS PROPERLY. LIKE, WHAT?
Fixing a TV that should be in the landfill years ago. I don’t know.
Testing environments:
SDR
(extremely off colors and banding still persists)
DoVi
(extremely off colors and banding still persists)
HDR10
(extremely off colors and banding still persists)
Verdict: Do NOT watch “The Super Mario Galaxy Movie (2026)” with this TV.
DO NOT.
(pretty sure this is using something like a globally lit VA panel)
Something like “Hybrid HDR10 with Dolby Vision” (1-minute cut of Aquaman (2018)) or hdr10+testlake is better, but not optimal.
- tv configuration
CHANGE THE EDID TO EDID 2.0.
GO TO SETTINGS -> INPUT.
EDID 1.4 WILL HAVE CONSEQUENCES.
- on the side of kde/etc.
SET THE RESOLUTION TO 4K60. LOWER RESOLUTIONS WILL HAVE CONSEQUENCES. (There is some stutter in watching 24p content; change to 24p if you like...)
Linux->enable hdr.
- tv configuration
IMMEDIATELY ENABLE PC MODE. NOT ENABLING PC MODE WILL HAVE CONSEQUENCES.
(I.e. colors that look off, undersaturated/oversaturated, wrong gamut, etc...)
DO NOT:
- TUNE THE SATURATION, HUE YOURSELF.
- TUNE THE SATURATION, HUE YOURSELF.
- TUNE THE SATURATION, HUE YOURSELF.
(If you want, you can do it... Colors will look off, STILL...)
(You should see a sharper image).
For brightest colors, ENABLE HDMI LIMITED RANGE.
The backlight will be too low, so set it to 60-70. NOTE THAT THERE WILL BE COLOR BANDING ON HIGH BRIGHTNESS.
Revised: Just use the default configuration. The color banding is unfixable anyway.
- on the side of kde/etc.
THIS IS FOR THE BRIGHTNESS/CONSTRAST VALUE OF 60. CHANGE ACCORDINGLY.
calibrate hdr brightness->peak=300~500cd/m2,ref=150~250cd/m2
- TESTING
install chromium and go to wide-gamut.com and test for some hdr videos. If wide-gamut.com works normally and you see a wider gamut (bright reds, different blues, etc.) then you're done.
Enjoy the WORST HDR EXPERIENCE EVER. DO NOT ASK ME WHY THE PEAK BRIGHTNESS IS SO LOW. BLAME THE PANEL INSTEAD.
Note 2: is the output signal now 8-bit PQ? Maybe PC mode forces it instead of 10-bit (which would require 4:2:2.)
