1440p/1080p Mixed Eyefinity?

jkteddy77 · Sep 3, 2014

Could I run a 1440p monitor in the center with 24" 1080p monitors on the sides, so I have the option of 1440p on single, or 1080p on all 3?
This "Mixed resolution Eyefinity" was added in driver 14.6 beta:
http://www.nag.co.za/2014/05/27/amd-reveals-eyefinity-3-0-and-new-multi-resolution-support/

Can anyone confirm if this would work well with 1440p and 1080p monitors?
Should I get 24" 1080p - 27" 1440p - 24"1080p or would this not even work?
or spend the extra $200 for 27"1080p - 27" 1440p - 27" 1080p

I want the best of both 1080p eyefinity and single 1440p since my rig has some horsepower to spare.

No reason this would have issues with the setup you're describing. Just use the expand or fill mode as desired and off you go. Of course, expand would be pushing even more pixels than a 4k display.

Yeah, I was planning on playing in fill/fit, so that the center monitor black-boxes the top of it until it matches the pixel height of the 24"... would that work? Then it would be like 5760x1080p native right? Only running the same number of pixels, as if it actually were 3x 24" 1080p's so the game isn't too demanding. Would it be more demanding this way than 3 actual 1080p monitors or... would it run the same with the center monitor fitted to 1080p to match the 24" monitors?

Also, could I connect the center monitor DVI to the Display Port in the back of my 290... I will also have my 39" 1080p above the 3 I will game on, meaning I have to use all 4 ports of my card... Will I still need an active display port adaptor for it to work?

For what you want, that sounds like the fit option, which I think adds up to around 6400x1080 if I did my math right. Fill would drive all 3 monitors at max resolution, but scale things so that if you set the 1440p further back it all looks good, which sounds really finicky.

Unfortunately, not an expert on outputs, so can't offer much help there.

Hmm.... would the virtual 6400x1080p play games correctly? Like would it run games in 5760x1080p with the virtual fit mode or would it only work on a few games?... I don't want any incompatibilities with games.
