[SOLVED] xrandr resolutions messed up, frequency out of range

My resolution got messed up for some reason today when I booted up my PC.

This is the xrandr output:

Screen 0: minimum 320 x 200, current 1024 x 768, maximum 16384 x 16384
DVI-D-1 disconnected primary (normal left inverted right x axis y axis)
HDMI-1 disconnected (normal left inverted right x axis y axis)
VGA-1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1024x768      60.00*
   800x600       60.32    56.25 
   848x480       60.00 
   640x480       59.94

Which is weird because I know my display should be a higher resolution and I have no idea why only those 4 modes are available.

I couldn't exactly recall what my display's highest resolution is, so from memory I tried adding these 2 modes

1680x1080_60.00
1680x1080_30.00

which resulted in errors in a black screen with the errors:

OUT OF RANGE 85.0 kHz / 60Hz
OUT OF RANGE 33.0 kHz / 30Hz

Check your xorg log, seems like no EDID is received.
What's the actual Monitor model? Do you have its tech specs?

Re: [SOLVED] xrandr resolutions messed up, frequency out of range

I've just restarted and that solved the issue, even though before it didn't. I think replugging the VGA cable fixed it. The log was fine. Looking up the model I found the maximum resolution was actually 1650x1050, not 1650x1080, that's why the out of range error happened. Making and setting a new xrandr mode to 1650x1050 did work, though the top was overflowing out of the screen for some reason. Didn't try to fix that, since restarting solved this.
