My screen is all messed up

[Rekindled]

Hello Internet,

I recently upgraded from vista x32 to Windows 7x64. After the instilation i noticed that my HDTV a 40' Soniq would no longer display at 1920x1080 and was stuck at 1680x1050 as the maximum resolution. However it was displaying the 1080p resolution fine when i was using it on windows vista. After further proding and some help from flyinfinni I have discovered that my screen is only displaying 16:10 resolutions and not 16:9 (it is a 16:9 tv). If anyone knows how to change the resolution back via windows that would be super

I am running an
i5 2.8
4gb ddr3 1600
2x4850s

And using the catalyst contro;l centre.

Thanks

Have you updated your video drivers and are you sure your TV can handle 1080p?
