Illustrator interface displays darker

Not sure why this happens, but it appears that Adobe Illustrator is darker than other Adobe software, and what it displays doesn't reflect what it exports. Here's an example of what Illustrator looks like:

This is what the exported image looks like as a PNG:

This started happening after I replaced my monitor's DVI cable with an HDMI one. However, it only seems like Illustrator was effected by the change. 

Any advice would be appreciated.
