Hi. I am not sure if this is the right place to post basic user questions, so if not, please direct me to a more suitable list.
I just tried to set up 2 monitors on my dual monitor NVIDIA card and I am confused with the result.
The monitors are:
1) 22' 16:10 LCD
2) 19' 4:3 CRT
I am running the LCD at its native res of 1680x1050 and the CRT is at
1280x1024. This almost works, save for a subtle issue - the aspect ratio
on the LCD appears to be incorrect. An image of a perfect circle looks
like a circle on the CRT, but when dragged to the LCD, I can tell that
the circle is vertically stretched into an ellipse (y > x).
I manually set the DPI to be 100x100. Here is the relevant line from the
(**) NVIDIA(0): DPI set to (100, 100); computed from "DPI" X config option
but it had no effect.
Here is the device section of my xorg.conf:
VendorName "NVIDIA Corporation"
Option "UseEdidDpi" "FALSE"
Option "DPI" "100x100"
Option "ConnectedMonitor" "DFP-0, CRT-1"
Option "HorizSync" "DFP-0: 30-110; CRT-1: 31-82"
Option "VertRefresh" "DFP-0: 50-150; CRT-1: 55-120"
Option "MetaModes" "DFP-0: 1680x1050, CRT-1: 1280x1024;
Option "TwinViewOrientation" "CRT-1 RightOf DFP-0"
Can anyone please explain to me why the circle looks stretched on the
LCD and if it is possible to do anything about it?
