Hi there people,
I recently bought a VGA splitter for my computer, I am trying to set up dual
monitors: one to a standard LCD monitor and another to a LCD projector.
I manage to get it working but win xp doesn't seem to pick it up as dual
monitors instead it mirrors what I have on the LCD monitor.
Any idea how to force a detection so that win xp actually picks it up as 2
independent monitors?
TQ
Yes, you need a video card with dual outputs or 2 cards. On cards with
dual outputs, there will either be 2 VGA ports, 2 DVI ports, or one of
each. Another way to check if your video card supports a dual monitor
setup is: Right click the desktop >> Properties >> Settings tab. If
your card supports dual monitors, it will say "Drag the icons to match
the physical arrangement of your monitors" and there will be a picture
of 2 boxes labeled 1 and 2 to represent dual monitors. Also, in the
Display drop down menu, if your card supports 2 monitors, there will
be two options, likely formatted like this:
<monitor name> on <video card chipset> AND
(Default Monitor) on <video card chipset> Secondary
All a VGA splitter does is that it splits a single VGA signal into 2.
The computer doesn't recognize the setup to be a dual monitor setup,
but a single monitor setup. So, in other words, you will just get
mirror images. A VGA splitter is pretty much useless unless you are in
conferences or something and you need to split a laptop VGA signal
into 2 to project a mirror image onto a projector screen. Almost all
new video cards have dual-monitor support. If you really need dual
monitors, then you could buy a new video card for under $100.
