Question on multiple displays

post #1 of 7
Thread Starter 
Im having a hard time finding an answer.

When using multiple displays IE: Clone, dualview, span..does it use additional GPU resources? Like would it reduce benchmark scores for instance =o

Google can be very chaotic with key words sometimes =\\

clone doesnt, dualview does. the amount of resources used is really small, unless playing SupCom on 2 screens.

having two supreme comander would bog it down so much that any thing estra from the dual view would be un-noticed.

My 3Dmark06 score didn't change with dual view...At least I don't think it did. I thik I'll run it again quick and see.

I used two monitors for a while, if you clone then all your system does is send the same data two different places; thus minimal extra work on your gfx. But if you extend your desktop so that you can use both monitors independently (which as far as I can tell would be the only reason to use two monitors except to show stuff to an audiance) then the nu,ber of pixels to be rendered goes up accordingly; so it uses a great deal more GPU time and gfx memory.
good luck

I don't understand why anyone would clone their display for a normal desktop PC. I work in the Audio visual industry and we use the clone option all the time. We use it to send the same information from the laptop to a LCD projector so that we can show a power point on a huge screen for major conferences. I don't understand why you would use it on a desktop though. Why would you want two exact images on two different monitors?

Clone still will hinder your performance slightly. I tested and saw about roughly 10fps drop in game from clone. Hard to test with span or anything since a lot of games will shut down one monitor if they don't support dual monitor
