1920x1200 via component out?

hondaman · 03-23-07, 09:02 AM

I have tried several things and cant seem to get it right. Do the drivers always consider using the dongle as tv-out? Can someone please share their xorg.conf for running component out to a DFP via the dongle?/component I am currently using a 6600gt agp and ubuntu 6.10

What is the problem that you're trying to solve?

I would like to get 1920x1200 resolution via dongle/component out to a DFP. My previous attempts so far result in 1280x720 resolution (i think that what it was) and the desktop hangs off the edges. I can barely see the top and bottom bars on the desktop.

Should I file a bug report on that? I'm not sure its a bug, or if I'm just doing it wrong.

If you're using component out cables, then its not a DFP, its a TV, and you'd need to select one of the TVStandard parameters documented in the driver README.

The 'hangs off the edges' behavior that you described is expected with TV-out, and is known as Overscan. See the driver README for more details.

Yes, I did read about overscan. But I couldnt find a way to underscan (shrink) the picture to fit the screen. Is this possible?

There is no guarantee that you can reduce overscan to fit the exact dimensions of your TV. You can use nvidia-settings to adjust the overscan (or the TVOverscan option, as documented in the driver README).

Ok, I have put this line under "Screen"

Option "TVOverScan" "0.0"

To the best of my knowledge from the readme, thats how it works, correct? I still have overscan problems. I do not see anything in nvidia-settings that talks about overscan.

Here is the bug report

Have you tried setting it to 1.0 as well (or any intermediate values)?

What is the output from running 'nvidia-settings -q all' ?

K, I tried .5, 1.0, and 2.5 and all made any noticeable difference. The output of nvidia-settings -q all is attached

Based on the information here, it looks like your graphics card's TV encoder might not support overscan adjustment. It works for me with a 6600GT card.

hondaman · 03-23-07, 11:53 AM

oh reeeeeeeeealy. BFG doesnt do overscan adjustments (least in the 6600gt)? Thats disappointing. Is there a way to tell if a manufacturers card does or doesnt before making a purchase? Is there a bios update for the card that I can apply?

netllama · 03-23-07, 11:59 AM

I didn't state that BFG doesn't do overscan adjustments. I honestly don't know whether or not BFG's cards provide this functionality. However the card that you're using doesn't appear to be capable of making them if the TVOverscan option has no impact, and you do not have a slider for overscan in nvidia-settings.

Its possible that a VBIOS update would change this behavior, however only BFG (if they manufactured your graphics card) could provide one.

Overscan functionality isn't typically something that is advertised on the outside of a box.
