VGA DVI Dual output

[rocknrollstar]

Hi, we have several Acer M464 desktop pcs, and use a vga splitter to send the output to both a monitor and projector (IWB). Sometimes I notice shadowing/poor quality on the monitor.

 

The graphics card has a VGA and a DVi output. My question is, can I use both at the same time? I.e. put the VGA to the projector, and at the same time have the DVI to the monitor?

 

Or is a powererd VGA splitter better?

 

Thanks in advance!

Dont quote me on this but i think you can use both yes. Give it a go and see what happens

Yep, we've just run up a PC connected to a projector and tft using this method.

Yeah this is possible. On one of our dual headed cards we can run two monitors as a direct copy of the other. Can be quite useful, actually.

A couple of things worth noting mind, if your projector's a distance off a powered splitter will give better results (signal degredation and all that). Also, I noticed once that a powered splitter without the power applied can cause the ghosting you mention on the screen - some muppet had unplugged the splitter and it took ages to figure out!

Great, thanks for the replies. Just to check, the vga and dvi ports are direct from the motherboard (onboard), not a seperate graphics card. Does this make a difference?

 

Thanks.

Shouldn't do, you should get the same output on each one as mentioned before.

 

Unless there is a bios setting or something else to disable it.

 

Give it a go and report back.
