How are you connecting this TV to your computer?
What resolution are you running? You setting your resolution to the tv's naitive resolution? What is the max resolution you can send through the connector that you are using? Some tv's are 720p but can't accept that resolution if you use S-video or the Yellow composite input.
FALCONWING may have not done everything correctly so I urge you to do more research. For all we know, falconwing could be a mental patient who gets internet access once a week.
As for the brand, I'm a Samsung Fan.
