Black bars around HDTV?

[bassballboy]

I haven't used my HTPC on my upstairs TV in a while, so this came out of nowhere for me. There are black bars around the picture, and I can't find a way to fix it. I updated the drivers on my video card (ATI3850). The TV is a Samsung 50" 1080p plasma. I have the TV set to "just" fit" but 16:9 is little better. The GPU is set to 1080p.


How do I fix this? It's driving me nuts!

A full shot of your tv would help more, but from what you are describing it sounds like overscan/underscan settings in ati control panel. Have a look here-->http://superuser.com/questions/57239/overscan-in-catalyst-control-center

Hope this helps....

Also- Leave your tv size set at 16x9 so it can output natively to 1080p....later

Excellent.

I had this same problem with my little HTPC, tried to fix it, pulling out my hair to th epoint where I decided to use it as a server instead.

I have a new server box in the works, figuring this out will allow me to return it to HTPC service

Indeed, set it to no over/underscan and then set the TV to use 1:1 mapping would do the trick. Looks like you have it all set.

I have seen TVs that cannot do 1 to 1 pixel to pixel mapping, which seems totally odd to me...

Sometimes with those fussy TV's you have to set a custom 59.xx hz refresh rate, or drop a couple of pixels with a custom resolution (1360x768 vs 1366x768, creates super thin black bars on each side), or just drop hdmi and go VGA instead as a last resort.

Using one of those three tricks often fixes the fussiest of TV's.

Well, even tho your problem is fixed, I figure I'll post a few more suggestions.

• If you're gaming, make sure your TV has the input labeled as "PC", and your PC is connected to either HDMI 1 or HDMI 2 (one will be labeled HDMI/DVI).
• When you have "Just Scan" selected, you need to change the videocard's HDTV output to use 0% overscan (Nvidia and ATI default to 5% overscan).
• Make sure that any additional picture options, especially anything related to motion correction (like that "120Hz" junk) is turned off, and that your sharpness is either set to 10 for film, or 50 for PC output.
