Can I get verification that the display is 8-bit?

In the attempt to avoid eye problems, I’m starting with the display and continue to dig into the intel graphics. First, I am hoping to know if the display for this laptop is natively 8-bit.

Yes, the panel is 8-bit


Pardon my ignorance, but would you please help me understand how this relates to the bit depth of the display? Is there another topic in the forum you can link me to?

@dkt01 Here’s a link that explains some concepts about bit depth as background.

The link provided before to the panel is the physical component of the display that makes the image (the ‘display’ is an assembly of components around and including this panel, so to speak). This panel’s color space (and thus maximum quality/depth it can display) is sRGB, which has 8 bit depth. Since the panel is 8-bit, the display and the laptop are 8-bit as well

For some real life confirmation, xwininfo -root | grep Depth on my Batch 6 displays Depth: 24 on the internal monitor. This is the 8-bits-per-color of sRGB, and thus is 8-bit (the name of the field is a bit misleading, it should probably be ‘color space’, but oh well). Checking depth in windows could display 32 or 24 (I have not checked), as Windows sometimes pads sRGB with an additional alpha channel while still maintaining the bit depth of 8.

Windows reports it as 8-bit color depth

@Be_Far, thanks for including that, but my question was regarding the comment about eye problems. I have a fairly good understanding about color spaces in general.

Some panels use framerate control (FRC) to boost bit depth. 8-bit + FRC can produce 1B+ colors at the cost of flickering.

I’m assuming what @John2 means by “native 8-bit” is “not 6-bit + FRC”


@dkt01 I am trying to see if there is any use of temporal dithering. From screenshots it seems on the gpu side, you can select specific color profiles by bit depth. I’m hoping to simply match an 8 bit panel with an 8 bit color profile to avoid 8 bit + 2 FRC.

@feesh beat me to it :grin: thanks for chiming in.
