Sample EDID info from a few monitors (video resolution parameters)

This post was written by eli on July 4, 2015

On Linux machines, there’s a command saying

$ xrandr --verbose

which outputs a lot of information about the display, in particular the EDID information obtained from the monitor. Among others, it’s a detailed listing of the video modes that the monitor is willing to accept. These modes are usually the standard VESA graphics modes, but there’s no guarantee that they are. But in reality, they are probably all industry standard, in particular those repeating themselves in the different dumps.

Also in reality, most monitors will display anything thrown at them, as long as it makes sense (or not) even if the graphics mode doesn’t appear on the list. After all, no monitor manufacturer wants the screen to be black when the competitor’s monitor shows as image.

So here are two such dumps. The first one is from my Lenovo Yoga 2 13″ (non-pro) laptop connected to a Dell P2415Q monitor, so the first set of data relates to the laptop’s own screen, and the second set to the much better external monitor (which goes up to UHDTV at 60 fps).

The second set is just my desktop, which is connected to a Samsung 23″ LS23ELDKF (a.k.a LED XL2370HD) monitor.

So the Laptop first:
