Is it possible to add unsupported resolution when monitor is connected via DVI -> VGA (passive probably) adapter? The problem is that the monitor (Acer AL1916W) is reported as CRT monitor, mainly because it connected indirectly to the GPU (nVidia 9800GTX+ using driver v310.14 @ xubuntu 12.10). I've tried adding custom resolution with xrandr, but result was following:

xrandr --newmode "1680x1050_60.00"  146.25  1680 1784 1960 2240  1050 1053 1059 1089 -hsync +vsync

xrandr --addmode DVI-I-0 1680x1050_60.00
  X Error of failed request:  BadMatch (invalid parameter attributes)
Major opcode of failed request:  153 (RANDR)
Minor opcode of failed request:  18 (RRAddOutputMode)
Serial number of failed request:  31
Current serial number in output stream:  32

The persists on windows too, but it can be fixed by adding custom resolution from nVidia Control Panel.

Thanks in advance!

  • Related: How to set a custom resolution? May not be a duplicate; could be typo "DVI-I-0" instead of usual "DVI-0" in the linked post, or different hardware connection type requires different configuration? Any user with similar hardware setup should clarify this. –  May 26 '19 at 18:44

I had the same issue. Please review my document how I fixed it.

I hope it would be helpful.

    Welcome to Ask Ubuntu! Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. – fossfreedom Jul 31 '13 at 13:11
  • To reviewers: This dated answer linked to a shared document that suggested to check monitor hardware information using Windows-only tool, then copied to X configuration in Ubuntu. If someone can figure out how to get similar information using Ubuntu/Linux only, this answer would have been useful. Decided not to quote the lengthy steps because of this reason. –  May 26 '19 at 18:35
  • Related: Display monitor info via command line, may be useful to replace *the Windows-only step. This can only be clarified by users with similar hardware setup, however. –  Jun 08 '19 at 16:49
