dual monitor with different resolutions.

[roRisc]

I'm getting a dvi-to-analog converter and I want to know if I can run dual monitor on an Ati Radeon9700SE, with the 2 monitors having different resolutions (I have a 19' and a 17')

Any RTFM links regarding this issue would be wonderful.
thanks.

If your card has two seperate video outputs yes. The radeon utility I think will mostly set it up for you..

I would say you should probably buy another (pci) video card. I am not quite sure this applies, as it is a little different then my question but Someone told me that if you do that both monitors will be dark, so you need a powered converter. those set up back about a hundred bucks (usd) so you should prolly just buy a new video card. It is explained in this (http://www.computing.net/hardware/wwwboard/forum/27912.html) thread over at www.computing.net. Goodluck!

That one is two seperate, by a simple modification like so :

#Section "Screen"
# Identifier "Screen0"
# Device "NVGLX"
# Monitor "Monitor0"
# DefaultDepth 24
##**********************************************
# Option "TwinView" "True"
# Option "SecondMonitorHorizSync" "31.5 - 64.3:
# Option "SecondMonitorVertRefresh" "60"
# Option "TwinViewOrientation" "RightOf"
# Option "MetaModes" "1280x1024,1024x768"
# Option "NoLogo" "True"
#**********************************************
# Subsection "Display"
# Depth 24
# Modes "1280x1024"
# ViewPort 0 0
# EndSubsection
#EndSection

you would be able to do spanned or (xinerama)

uncommented of course.

Here's one thing to consider about running Xinerama (dual head spanning) from the HOWTO (http://www.tldp.org/HOWTO/Xinerama-HOWTO/planning.html#AEN75):


There are several UI issues which are specific to Xinerama with most current generation window managers (see Section 9) do not address well. The most anoying is the poor handling of dead areas.

Window managers assume the display area is a rectangle equal in size to the heighth and width of your total desktop. If you use more than one display resolution in a Xinerama setup your desktop will be non-rectangular. This results in "dead areas", areas which do not exist on your display, but window manager interpret as "Empty". Many window managers will try to utilize this dead area for new windows. The result is windows which are inaccessable. As window managers become Xinerama aware and this problem will go away quickly.
