\nRHEL dual monitor
\nDual monitor test on RHEL 4<\/p>\n
Video card<\/p>\n
nVidia 128MB PCIe x16 nVidia Quadro NVS 285, Dual DVI or Dual VGA capable<\/p>\n
Monitors<\/p>\n
Two monitors have different resolution each other;<\/p>\n
1)DELL 2007FPW, 1600×1200
\n2)DELL 1707FPVt, 1280×1024<\/p>\n
Test methods<\/p>\n
There are two different mode for utilizing 2 monitors on Linux. Both of them can be configured in \/etc\/X11\/xorg.conf file.<\/p>\n

Results<\/p>\n
TwinView shares one X session and it looks virtually one big screen. However, failed to have a optimal resolution since two monitor has different resolution and ether of them does not work in maximum resolution and it looks like big font or low resolution.<\/p>\n
Dual monitor looks like you have two machines since it shows you different X session on each monitor. Mouse pointer moves one to another back and forth. It works fine and each monitor has menu bar separately. Best solution for two monitor with different resolution.<\/p>\n
