Please help with Monitor refresh rate..

Please help, i just bought a samsung 40" LED tv i use for a monitor, and its a 120hz tv... but when i try to change the refresh rate of my computer, the last option to choose is only 60hz... the text on my screen is kind of blurry, not as sharp as it was through VGA..

can anyone tell me how come i cant get my computer to output in 120hz..

running Win 7 ultimate 64bit, HD Radeon 4850, AMD phenom II quad core processor black edition... not sure why i would be having trouble..

using DVI to HDMI cable for connection... any help would be greatly appreciated, waiting by patiently for your inputs

also there is a 1 inch border along the entire screen in black i cant get rid of... display shows 1920x1080


OK ... so i updated my cards drivers... and restarted, now the border is 1 inch over the display, but settings still show 1920x1080..

ok i found it for whoever needs to know.

Even though you can force a 120hz refresh through the Nvidia control panel, I think the TV only takes 60hz refresh rates listed in the manual (pretty sure no TVs accept 120hz inputs but that would be nice). Check the manual for PC compatible timings.
As far as the overscan, make sure the PC is plugged into HDMI-1 on the TV. With the remote, re-name HDMI-1 to "PC" and set picture size to "just scan".

If you already did all that, downloading the latest Nvida driver should fix it (as it did for me). These sets are very PC freindly so you should not have any overscan.

I've experienced exactly the same thing (on a Samsung 52" lcd). It isn't the refresh rate, it's the overscan/underscan settings.

Open Catalyst Control Center and find DTV in the list on the left. Click on this and you should get a list of options and settings. The one you want is "Scaling Options." Click on it and you should now see a slider labeled Underscan at one end and Overscan on the other end. Slide the pointer all the to Overscan (0%).

The desktop should now fill your screen (no borders) and the text should be sharp.

Hope this helps.
