BleepingComputer.com: New Video Card?

I just recently purchased a Gateway GM5472 and hooked it up to my cable. I notices that the picture (although viewable) seems to be quite dim -- not as vivid as I expected it to be. Is this something that can be fixed with a new video card (if so, what would be the best one to get?) , or would I need to replace the tv tuner itself (If so, which one?) I don't know if it matters any, but when I first received the computer it came with Windows Vista which I did not like and replaced with Windows XP Media Center. I've listed the specs below. Thanks in advance for any assistance.

If brightness/dimness is the issue...I would suspect the monitor before thinking about the video card/drivers.

Do you have access to a second monitor?

Thanks for the speedy reply -- I neglected to mention my monitor is my television... The picture when normally watching television is much better than when I watch it through my computer -- which if different than I expected it to be. Its a 42'' Sony Grand WEGA (http://www.sonystyle.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10551&storeId=10151&langId=-1&partNumber=KDF42E2000)

OK, thanks...but you did not answer the question about a "second" monitor, since we can consider your TV as your first monitor.

The LCD device probably has some controls that you can adjust to compensate for viewing problems. According to what I just read, that seems like the resolution that you will have to attempt.

You could also try updating the drivers for your system...drivers can become damaged and damage can affect viewing quality.

Unless your video card/chipset is failing...I don't think a new video card is the way that I would suggest going.

That's why I asked if you had a second monitor, it's easier to narrow the choices by simply connecting a monitor and seeing if the problem persists. If it's a driver or video card/chip issue, it should apply to a different monitor. If it's an issue pertaining to your LCD device, it won't impact a different viewing device.

Ok -- I updated all drivers and installed NVidia PureVideo -- also hooked up the computer to another monitor (not t.v.) The picture is great until I try to watch television -- the picture still doesn't look crisp -- its like watching television on a 20 year old analog television -- sorry but thats they best way i can explain it... I also tried to play a game and the graphics look great, but wouldn't run on highest settings...
