[...] to be designed for a TV. There are lots of solutions to the problem, starting with messing with NVida’s driver settings, just using the VGA cable (or a DVI one, for that matter). The cleanest solution to this is, of [...]

Thanks. The modeline-trick didn’t work, but got me going to a working solution:
1. Added

Option “UseEDID” “False”
Option “ExactModeTimingsDVI” “True”

to the “Monitor” section.
2. Restarted Xorg/gdm.
3. Ran the nvidia-settings program as root.
4. Saw that even more resolutions now was detected, strangely enough.
5. Changed to my preferred resolution, and it worked without overscan!
6. Saved the X configuration from nvidia-settings (check for merge with existing file, so you keep the two beforementioned lines).
7. Enjoy.

I can, ofcourse, not guarantee that this works for anyone else, but it’s worth a try.

Wow, thanks! With the open source ATI drivers and HDMI out, my Sony 32″ LCD was cutting things off (the proprietary Catalyst has overscan correction, but I wanted to try the free drivers), and this worked great. I used the findcoords program and used new modelines and set them with xrandr, and it seems to work just fine, cool. Now, if only sound will start outputting out of HDMI like it was earlier, don’t know why it stopped working….

I also had this problem, and your page was the very first to appear when doing a google search, thank you for the suggestion to look on the TV itself. I found that my Samsung 40″ Series 6 TV had a display mode of “Just scan” to fix the problem. Without it, all four sides of the picture were indeed cut off.

Thanks for the info!

My setup is an NVidia graphics card with HDMI output going to an Panasonic Viera 1080p TV – solved by turning off the Overscan option in the TV settings menu.

Dudes,
I just wasted two days playing with modelines and my Toshiba Regza TV via DVI-HDMI. I guess it doesnt matter what are the modelines settings if connected via HDMI. Finally, I found a setting in the TV menu to use “native” screen size (used to be “natural”) and it works perfect with ANY modelines.

cheers

@Chris On my Toshiba XV365DB I can solve the problem by selecting 'game mode' in the setup menus of the TV itself. Maybe not an elegant solution, but it works for me (and is very easy). Hope this helps someone.

Thanks so much for your help. After reading this post, I knew to look for the 1:1 mode on my TV, which I found. It was MUCH easier than all the messing with xorg.conf I tried.

Great post.

My resolution ended up being at the TV. My Philips had a setting called “Unscaled” that did the 1:1 pixel mapping that you mentioned. For others reading this, I am not terribly happy with the Philips. It is a FullHD, 1080p 1920×1080 TV and the quality from the PC is still isn’t that great.
