What card did you get, what screen are you using and what is the natural res of the screen? And what are you using to connect to the screen? VGA, DVI, HDMI?
Here is a link to the card: http://www.newegg.com/Product/Product.aspx?Item=N82E16814121852
Im using a samsung smart tv for the display and it says the recommended resolution is 1080 and i am using hdmi to connect.
Since it is a TV, there is a good chance that the real resolution on the TV is 1600x900 and not true 1920x1080.
* What is the exact model number on the TV?
Anyways, if the resolution is 1600x900, then you should always run the computer at that resolution. Don't use any kind of stretching or positioning features in the video card control panel to make up for the fact that it is not true 1080p. This only makes the picture quality worse.
Also, if you want a TV to actually look as good as a computer monitor, then there are LOT of settings that you will need to change on the TV. I have actually posted about this in multiple threads to help out other people who were having problems getting their TV to look decent on a computer. If you would like me to give you a full list of settings to change on your TV, let me know.http://www.tomshardware.com/answers/id-1988910/hdtv-quality-monitor.html#12490011http://www.tomshardware.com/answers/id-1988910/hdtv-quality-monitor.html#12490590
