Try the other DVI port to see if that enables 2560x1440. If it does not, then 1920x1080 is the maximum supported resolution and you will need to upgrade your graphics card.
I am happy to provide you with some suggestions on an upgrade if you can provide the following.
What will you be using the graphics card for? Gaming etc?
What budget have you got?
What are your current PC specs?
What Power Supply are you using?

It's currently connected with HDMI. This monitor does not have a DVI port.
Windows 7, AMD Athlon II X2 255 Processor 3.10 GHz, 4 GB RAM, Antec EA-380D (380W) power supply.
The most demanding graphics use on the PC is large pdf plan viewing / CAD files. PC is quite a few years old now so not looking to spend a lot if a new graphics card is needed.
Thanks for your recommendations.
That will be the maximum resolution for HDMI on the 3000 series.
Due to the low wattage of your power supply, a Radeon R7 240 2GB GDDR5 or a Radeon R7 250 2GB GDDR5 would be my recommendation, depending on your available budget.
