RTX 1660 super dithering see it in action

smilem

Hello, finally got my hardware and made first video.

RTX 1660 Super on 8bit

BenQ BL2410 8bit - DisplayPort

dGray RGB 127 127 127

Win 10 LTSC 21H2 19044.2846

Nvidia driver 31.0.15.1694 / 516.94

Still debating what to include in video text overlay and description. Suggestions welcome.

Tested the usual suspects ditherig 2.21, colorcontrol 10, novideo_srgb. They have ZERO effect. Dithering is shown OFF but as you see it is not.

What you recorded, is monitor's pixel inversion, not dithering. Dithering is lower layer which masked with monitor pixel inversion / FRC. Its hard to catch it with camera, only via HDMI recorder which can record 4:4:4 color (without loss)

I think in your benq you able to see horizontal bars without additional optics?

What is being displayed on the screen? A still image? A color sample (what color)? An animation/video?

Like the description says, the video is Pixel Flicker of a slow motion capture with 120/240/480/960/1920FPS of a BenQ BL2410 8bit Monitor - DisplayPort, to a Win 10 LTSC 21H2 19044.2846.

I have the Arc A770 le and the same Win 10 LTSC 21h2.
I don't see dithering on my build, but the strain is present.
I use this wallpaper as test. If I see banding, Dithering is off, otherwise the image is smooth.

The problem for me is this Windows version.
My last safe build was with Win 10 1809 and all updates blocked.

I wrote you pixel-inversion, not FRC 🙂

btw, mine bl2420z also mention as 8-bit, but when I get panel datasheet, found it accept 8-bit input data, upbit and send 6-bit into matrix. All 27" 2k165, 2x 27" 2k75, 27" FHD 100, and few 24" FHD 60 I checked, were 6-bit ^_^
