Catalyst thinks my LCD is a projector, rez/scan problems

I have a Radeon HD 7770 connected to a Philips 19PFL3504d/f7 LCD screen, rated at 720p.
When I set the resolution in Catalyst (or MCC) to 1280x720, the display is unusably small. It looks like 480 or so. It also doesn't give me any options for refresh rate besides 30Hz (supposed to be 60Hz.) In some places, the display is identified as PROJECTOR(1) and in other places, PHILIPS RADEON HD 7700 SERIES. There's a little projector icon in the setup page. The display information shows a maximum resolution of 1920x1080 and refresh rate of 60Hz, neither of which I can change. It looks like something autodetected my LCD screen as a projector and isn't displaying the correct resolution.
The workaround I've been using has been to set it to a much higher resolution. This way, I have enough screen to use but it looks grainy and text and window sizes are off. Sort of like 800x600 displays from long ago, but wide. Besides the monitor damage and eye strain I'm sure this is causing, I cannot do this anymore because I've run into an application that requires the proper resolution.
In terminal mode, about a character and a half (20ish pixels?) get cut off from each side. Not sure if this problem is related.
Sorry about the poor writing. It's late and I'm pretty frustrated. If it's unclear, I'll edit tomorrow.
