Thanks that did give me more options. Where and how would I put 1280X1024 into the mix?

Open the text editor and create a file, name it .xprofile (makes it a hidden file) and place in your home user's folder. In that file copy/paste this below, then reboot to your user. That was using my monitors and command cvt, so may not work for yours. If you need a higher resolution later, then just follow the example in the file.
xrandr --newmode "1280x720_60.00" 74.50 1280 1344 1472 1664 720 723 728 748 -hsync +vsync
xrandr --addmode VGA-1 1280x720_60.00
xrandr --addmode LVDS-1 1280x720_60.00
xrandr --newmode "1280x720_70.00" 88.25 1280 1352 1480 1680 720 723 728 752 -hsync +vsync
xrandr --addmode VGA-1 1280x720_70.00
xrandr --addmode LVDS-1 1280x720_70.00
xrandr --newmode "1600x900_60.00" 118.25 1600 1696 1856 2112 900 903 908 934 -hsync +vsync
xrandr --addmode VGA-1 1600x900_60.00
xrandr --addmode LVDS-1 1600x900_60.00
xrandr --newmode "1600x900_75.00" 151.25 1600 1704 1872 2144 900 903 908 942 -hsync +vsync
xrandr --addmode VGA-1 1600x900_75.00
xrandr --addmode LVDS-1 1600x900_75.00

then open Display in your OS and set it to one of those if you can.

You can find your own cvt settings for modeline by following example below.

Code: Select all

~ $ cvt 1600 900 60
# 1600x900 59.95 Hz (CVT 1.44M9) hsync: 55.99 kHz; pclk: 118.25 MHz
Modeline "1600x900_60.00"  118.25  1600 1696 1856 2112  900 903 908 934 -hsync +vsync

post results and I will work it up for you. What is the highest refresh rate you can run on your monitor?

Thanks that did it. Now I have good resolution on the external monitor. I learned something today about adding that hidden file with Xrandr in it.

Just realize and remember, that's not global but just for your user. If you create a second user, you'd need to put a copy of that .xprofile into their user folder too.

And that after giving up! :wink:
So this is solved? That's great; please mark the topic as [SOLVED] in the title of the very first post, so it can be seen from the forum overview. Thanks!
