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.)

typically mp2 is for dual compute units (actually each one has only 4 SP... so the metrics above are for MP2)

lossless is truly lossless

losslesshp is +10% perf for a slight file size increase

lossless is actually faster than x264 and x265 lossless mode while being more efficient

lossless corresponds to a quality level of -12 (q=-13), inaccessible through normal modes ([0...51]) i.e. effectively disable quantization. for x265 this is qp=4, x264 qp=0.

example:

frame=141336 fps= 78 q=-13.0 Lsize=439591079KiB time=01:38:14.88 bitrate=610890.2kbits/s speed=3.26x elapsed=0:30:08.07

losslesshp on the 4k 98min video gives you a 450gb file (about 20x vs the original) for a compression ratio of ~4.9:1

a73 (2)

yoshi_fp36 đã đăng vào 16, Tháng 9, 2026, 5:43

so its that the 76? number comes from prrt+store queue (-1 for the extra cache miss load??). a73 can do at most 66 speculative reg writes in flight and 10 (or 11) indep stores. a73 automatically discard nops so any result that i measured is in some form useless.

(m1 has a ~330 entry coalesced rob for about 2300 nops and a 630 entry prrt)

cortex a73 "rob size" is > 76, if you max out the speculative intrf and fprf you only get ~70 instrs measurable, a73 automatically eliminate nops so we don't know what could be there, sorry for not able to measure things....

(i tried using the coalesced rob method but got nowhere)

probably 76 is equal to something like prrt+store buffer
