How do I change HDMI monitor settings from Linux?

TheJooomes · 11-13-2022, 07:54 PM

I have my PC connected to an Insignia 32" TV which has greyed out options for color, tint, and sharpness. I especially need to adjust sharpness because it's way to high and looks terrible. It's hard to look at and use. I looked it up and supposedly the video output device is suppose to adjust those greyed out settings when using HDMI. So how would I even acomplish this on Linux. I'm using Void with an RX560 using kernel 6.0.7_1 and Mesa drivers with KDE.

First hit googling kde calibrate color:

mrmazda, I do not think the color management will solve OP's problem. That will put another layer of effect on top of a problem. One need to set those parameters (color, tint, sharpness, etc) in order to create an accurate color management profile and I don't think OP has the color management tool for this either.

TheJoomes, you'll need to share the exact model name of your monitor. Does these two links help any? I used the following search terms "linux hdmi control sharpness" to search with.

The settings asked about should be available on the tv itself, thus linux disables those settings.

My TV which is used as a monitor has its own settings for backlight, sharpness, contrast, brightness, and color.

Brightness isn't what I'm looking for. And the BestBuy thread described the issue I'm having, but didn't solve it. Specifically the TV is an Insignia NS-32D312NA15.
