yes but that's an intel paper saying that. Like I said, i think it's the same as sandy and ivy - technically, yes, they can support 3 displays, and intel goes around bragging how their chip can do 3 displays (and a certain competitor 'can't'). In reality, 2 of those displays have to be on displayport, and since not a single motherboard exists with dual displayport outputs, you can't do triple monitor off the iGPU. The only work-around is thunderport, which is like displayport, but it's mad expensive and no z87 boards have thunderport, only a couple z77 boards.

Now I'm not sure haswell is like that, but I'm guessing it is. You know, since I couldn't get 3 displays to work and all.

did you run out of DVI cables? the U2312 uses a DVI cable (which you should be using anyway), i'd recommend finding or buying a DVI cable and trying that out, GPU's don't always do well with adapters and converters.

I posted earlier about this, but microcenter forgot the DVI cable (it's a 3 hour drive away, they gave me $20 back as refund for the issue). I'm actually using an HDMI cable with an HDMI to DVI adaptor to fit to my monitor, at the moment.

I'm not going to order a bunch of cables for guesswork though. That's not worth it. I'm pretty sure you can't do triple monitor off haswell...

I ordered a displayport cable. This isn't really relevant to the thread, but I'm going to plug my monitor into my mobo via displayport, and then into my gpu via dvi to hdmi to gpu. That way, when I game, I don't have to manually swap cables on the back of my pc, i just hit a button on my monitor, and in screen resolutions, I just disable one input or another based on what I am doing (gaming, or GPGPU work).

holy crap I can run 3 monitors off the igpu!

I have no idea why suddenly it worked. Maybe it was just the mess of adaptors and connectors I was using (i mean it was always hdmi, dvi, vga, nothing changed). I think I used vga to dvi last time so that's why maybe it didn't work. I wasn't even messing around to do 3 monitors, I just took out my GPU temporarily for some work and plugged the cable into whatever, figuring I'd have to run 2x monitor.

so.... awesome! oh my god i LOVE haswell! this chip is freaking AWESOME. I know for most people they dont care about igpu, but this is a HUGE deal for me. It was the whole reason I sold my ivy in the first place, to have a triple monitor iGPU. then i eventually 'realized' it could only do 2.

im SO glad to be wrong and full of crap! oohhh my god this is too awesome for words. Im hoping the iGPU is strong enough on haswell that I can even run SC2 on medium or better graphics 1080p, now that would be really beast (and then keep my GPU making money for me while I game). awesome awesome awesome awesome AWESOME!!!!
