Can my r7870 run two 2560x1440 monitors?

ftlepore · Jul 24, 2013

I'm trying to figure out if I can run two monitors at 2560x1440 resolution. The video card (MSI R7870) has one HDMI 1.4a port and one DVI port. I can't seem to get a straight answer as to whether the HDMI 1.4a port can support 1440p. The monitors in question are the X-Star DP2710.

The video card also has two Mini DisplayPorts, but to be honest I've never used them. Are these an option? And if so, what adapter might I need?

If I can run the monitors at 1440p, will a regular HDMI-to-DVI cable work (I'm using one currently), will I need a specific cable, a specific adapter, or otherwise?

Thanks in advance for any help you can provide!

HDMI 1.4a CAN support that high of a res, but only at a 30Hz refresh rate, after creating a custom resolution (it defaults to 1080p). I hope you won't be gaming with that 7870 accross two 1440p monitors.

2560x1440 requires Dual link DVI. A regular cable won't work. So, be sure your adapter and/or cable does dual link.

HDMI 1.4a will handle 2560x1440.

I would only game on a single monitor, so presumably the one connected to the Dual Link DVI cable. The monitor itself comes with one Dual Link DVI cable. I'm just curious what I would specifically need to connect the second monitor once my single DVI port on the video card is in use.

Thanks for the quick replies!

So would this cable work for the HDMI port on an MSI R7970 video card? It seems significantly cheaper than what has previously been recommended to me.

ftlepore :

It should, if it is actually wired for dual link. Sometimes the cheaper/noname manufacturers only wire single link.
