It’s a TV set that’s either broken or very cheap, at least it doesn’t provide an EDID, i.e. it doesn’t tell which resolution it supports. What’s it’s native resolution, to add it manually? ---

Then the monitor is broken. Try this: ```auto xrandr --newmode "1680x1050_60" 147.14 1680 1784 1968 2256 1050 1051 1054 1087 -HSync +Vsync xrandr --addmode HDMI-0 "1680x1050_60" xrandr --output HDMI-0 --mode "1680x1050_60" ``` ---

So, I think figure it out. I need to change display setting called “timing” in Linux. I need to manually set changes on Horizontal and Vertical settings Like: “active pixels”, “front porch”, “synch width”… So how can I do that? ---

That’s the xrandr --newmode line doing, the numbers are the pixel and timing values. The error you’re getting rather points to the mode already existing, can you please ignore the error and continue with the second and third command? ---

My resolution settings on (Nvidia control plane) in Timing standard: Auto that’s why it look so pixeld i changed manual to ``` Horizontal Vertical ``` Active pixels: 1680 1050 Front porch (pixels) 104 1 Sync width (pixels) 184 3 Total pixels 2256 1087 Polarity Negative (-) Positive(+) after typing this in Nvidia control plane my monitor was set to correct res. But i don’t know how to do this on Linux? [Next page](https://forums.developer.nvidia.com/t/display-issues/82173.md?page=2)
