Hey all.

Looking for some assistance here since I cant fix this issue on my own.

I have two 2560 x 1440 monitors plugged into my R9 280x on my desktop.

However the main display shows full res. But the second monitor (the Dell) only stays at 1920 x 1080. Im using the same DUAL-DVI cable for both monitors yet the Dell wont show full res.

Ive tried uninstalling the display drivers and reintalling the latest ATI Catalyst Control Center.

What other options do I have?

Exactly which R9-280X do you have?
They may have different output options.
If one of yours is SL-DVI-D it may only support a lower resolution.
If you have a HDMI connection available, you might want to try that.

If you connect the Dell to the main output, does it show full resolution?

It is a confusing area that I also do not completely understand.
But, I think you need dual link port and cable both to show full resolution.
