Hi,

I'm not very well up on graphics cards and need some advice.

I currently have a ati radeon HD 6450 512mb ddr3 card in my system.

ATM money is tight but I want to add another monitor, what I wanted to know is would it work if I bought another radeon HD 6450 but this has 1024mb ddr3 memory.

would this work if i used the dvi connections on both cards to use 2 monitors?

sorry if it is a stupid question but I'm not knowledgeable on GPU's.

Thanks.
Rob
 
Yes, having two cards and using each for display will work, so long as Crossfire isn't turned on. Just hook up the monitors as you want them. If you crossfire them then the ports on card 2 will be inactive and only those on card 1 will work (but with the processing power of both cards going to them).

Don't forget you can connect two outputs to any card, so you could just connect up your other screen to your existing 6450 and wouldn't need to buy another one. For work, normal desktop, and even Blu-ray playback a single 6450 will happily run 2 screens without issue, but gaming is always going to be stretch for the little bugger. :)
 
thank you for that advice,

on my card there is only a dvi and display port, can I connect a second monitor to that extending the desktop?

thanks,
Rob
 
Yes. You can get display port to hdmi (and dvi) adapters I believe, if 2nd monitor doesn't have display port. You can extend, duplicate or switch between the displays by pressing windows key + p (assuming Windows 7).
 
Also if you are extending desktop you can switch which display is primary and secondary display. On laptop at minute so can't open CCC, but I believe you just go in to display properties, click 2nd mouse button and select 'swap'.

Click to expand...

You can do this within Windows as well.

Which 6450 do you have OP and what connections do both monitors have?
 
sorry if the info is not what your looking for, on gpuid: ati radeon hd 6450, GPU: Caicos, 40nm, release date: aprl 19 2011, device id:1002-6779, 512mbgddr3 @ 800mhz, gpu clock:625mhz,
connections on back of gpu: dvi x1, displayport x1.

both connections on screens are vga connectors(there only 19" lcd) but i have 2 dvi-vga connectors.
 
Well I was talking about if it was Asus, Gigabyte, etc since they're the ones that decide what display outputs the card has.

But if it does have Displayport then get a Displayport to VGA, Displayport to DVI then DVI to VGA will not work.
 
subvender is HP, which would make sense as I got a hp cd with the card.

so do I run two screens off the DP or one from the dvi and other from DP?
