My PC has a Radeon HD5770 graphics card which is capable of 2560 x 1600.

Its got multiple outputs (HDMI, 2x DVI and 1x displayport) and is curently driving 2x 27inch monitors but these have to go.

Ive looked at some 34inch screens but these have a display of 3440x1440. Will my graphics card drive these screens and if so what resolution will be shown?

I appreciate there is a mis-match between graphics card output and monitor resolution but i dont understand what would be displayed if i connect one of these 3440x1440 monitors upto my graphics card. Do i just set my graphics card to output a resolution that the monitor happily shows which i guess will either be scaled or i'll have black bars at the edges?

Ultimately im probably better off buying 2x screen instead of trying to be clever with a single large screen?

Depending on how much memory the card has, you might be in luck:

Based on this post, it looks like you should be able to drive 3440x1440 ultrawide at native resolution, 60Hz as well.

If it doesn't work the monitor itself should offer the option of scaled or match resolution.

The card appears to have DP 1.1 and HDMI 1.3a.

A quick calculation suggests 3440 x 1440 x 60Hz requires 7.57 Gbit/sec of bandwidth between the card and the screen.

DP 1.1 has 8.64 .

HDMI 1.3a has 8.16 - all numbers pulled from Wikipedia.

I'm moderately optimistic. it will work, and you've got slightly better odds over DP than over HDMI.

If you do go down this path, consider a moderately curved monitor - I've found them more comfortable (my eyes have to do less refocussing as I move across the display) than a flat one.

I've used separate screens and a curved ultrawide. The ultrawide is less flexible (for example if a screen fails, or if you end up needing to loan a screen for some reason) but rather nicer to use.

No chance anyone you know has one you could take your PC to in order to know for sure?

Looks like there is a hack if you will accept 30hz.

4K is about 70% more demanding than 3440 * 1440, hence the lower refresh rate.
