Mixed resolution w/Catleap (1440p) and 2x 1920x1200 trying eyefinity/surround ?

Hi all,

For those who have a catleap or other 1440p 27" monitor, have you tried connecting mixed resolution and/or aspect ratios to see if you can get eyefinity or surround gaming to work? Does the catleap's lack of a scaler hurt it's ability to be used at lower eyefinity resolutions that would be needed when mixing with 16:10 or 16:9 monitors (e.g., side monitors of 1920x1200 resolution being run in 16:9 mode at 1920x1080 or lower resolutions)?

For example, how would eyefinity or surround work with the catleap in the middle, and two side monitors being 1920x1200? That's mixed aspect ratio of 16:9 in the middle, and 16:10 on the right and left (unless I'm mistaken on the aspect ratio conversions). Note that the 16:10 aspect 1920x1200 monitors I believe will support a 16:9 1920x1080 resolution.

So my guess is the eyefinity setup would drive all three monitors at the commonly supported 1920x1080 resolution, or other lower 16:9 resolutions, right? But, I'm really not sure because the Catleap doesn't have a scaler? Would I need to get the Microcenter version or other version that has a scaler? Ideally, I want to purchase the 1440p monitor around $300 and avoid spending more for the multi-input scaler.

Also, if anyone with Nvidia could provide advice, as I've never tried Nvidia triple monitor but I'm happy to use it if I can make this happen with Nvidia instead of AMD, it's just that I currently have an AMD card that I'm using for eyefinity with three other monitors @ 1600x1200 x3. I'm interested in eyefinity/surround gaming specifically, not just the multiple monitors for windowed desktop/browsing etc.

As far as I know surround gaming doesnt work with mixed resolutions. I have not tried it however.

Catleap has no scaler but your gpu can do the scaling.

That's too bad about surround gaming. However, maybe I should also ask the specific question: when eyefinity encounters mixed monitors, it somehow obtains the various supported resolutions of each monitor, including non-native resolutions. Then, eyefinity will pick the common resolution that all monitors support.

In the case of the catleap, does it identify itself as being capable of supporting other resolutions (e.g., 1920x1200, 1920x1080) to where eyefinity will pick up on that and therefore enable eyefinity as the lower resolutions?

Or, does the catleap's lack of a scaler prevent it from identifying itself as being compatible with any lower resolutions? how does eyefinity see it, would eyefinity say it's OK to select something like 5760x1200 or 5760x1080 even when a catleap (or other 1440p monitor) is connected? or does eyefinity just puke on itself if you connect one catleap with other monitors that aren't 1440p?

That's an interesting question and I'd be curious myself for reference. I will say this, I can select 1920x1080 as a screen resolution but I cannot confirm whether or not it's just my video card knowing that 2560x1440 = 16:9 and will allow you to select other 16:9 resolutions.

AMD's internal scaler will compensate for a lack of a scaler in the monitor. A buddy of mine has a Samsung 305T (a scaler-less 30" monitor) next to his 1920x1200 monitors. For hoots and hollers he can turn on Eyefinity on his 7970 without an issue. The 305T is simply treated as another 1920x1200 monitor, with AMD's internal scaler taking care of upscaling it to 2560x1600.

Good to hear. However, I'm a bit curious if anyone at all is using their new catleaps for eyefinity or surround - did anyone pick up three catleaps to flex the strength of their new SLI or crossfire rigs?
