Does anyone know if Gigabyte's GV-N750OC-2GI would support 4 monitors in this configuration:
DVI-I: output to 2048 x 1152 monitor
DVI-D: output to 2048 x 1152 monitor
HDMI: passive hdmi to dvi output to 2048 x 1152 monitor
HDMI: output to 1920x1080 tv

I've tried searching the web with no luck.

That's an excellent question and one that had escaped me, I'll admit. My apologies.

I actually wasn't sure but it turns out that passive HDMI -> DVI adapters only support single link DVI (maximum resolution of 1920x1200). While it seems that a HDMI 1.4 to DL DVI adapter should exist, I can't find one and there are similar forums expressing frustration that such an adapter simply doesn't exist: http://www.tomshardware.com/answers/id-2287249/hdmi-dual-link-dvi-conversion-adaption.html

What's you actual monitor model? The strange 2048x1152 monitors that is?

If they don't have displayport, then you'll need to...

Unfortunately GTX 750 (non TI) top out at 3 displays: http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-750/specifications

The GTX 750ti supports 4 displays.

Alternatively (and assuming you're not gaming here, because that'll demand a higher end card anyway) - some motherboard BIOSes allow you to enable onboard video as well as your PCIe card. If you have onboard graphics and you can enable it, that would give your the 4th screen. Windows 7 and later work seamlessly with multiple graphics cards and monitor arrangements.

Yes, that one will drive 4 displays and is a little more capable of a gaming card. It's a decent gaming card at 1080p. There's no need to mess with any display setting either, with multiple screens attached games by default will simply load on your 'primary display', which you set in the Windows 'screen resolution' settings. Simple.

Provided your 2048x1152 monitors (with their odd resolution) support DVI (digital) signals, you're good to go with the setup you suggest above.

would the hdmi output support a passive hdmi to dvi converter and be capable of achieving the odd 2048x1152 resolution?

If they don't have displayport, then you'll need to pick you GTX 750ti model carefully.

This one should do the trick: http://www.newegg.com/Product/Product.aspx?Item=N82E16814121855&cm_re=gtx_750ti-_-14-121-855-_-Product

According to the ASUS specs page the DVI ports are dual link http://www.asus.com/au/Graphics_Cards/GTX750TIOC2GD5/specifications/
Then you can go native VGA for your 3rd screen and native HDMI to your TV.

That should work. The other option would be a model with a displayport and grab yourself an MST hub.
