How do I get underscan with radeonhd ???

[batesman]

@ Kano

Sure, you're right. Usually it's best to use native Res.. But I wanted to use as few cabling as possible to Connet the HTPC with TV AND A/V-Reciever. And I don't believe it makes any difference in quality for watching TV if use VGA/native Res. or HDMI/720p. But to use HDMI cabling makes it much easier.
But if I don't get it running this way I'll fall back to "your" solution.


PS: nix f?r ungut ;-)

@batesman

DDC will report display size - so dpi is correct for X already ->

xdpyinfo|grep dots

also every video player can setup the aspect ratio, for mplayer it is

-monitoraspect 16:9

which could be put in .mplayer/config too as

monitoraspect=16:9

Your way is definitely not the best one - always best is it use native res.

@Kano

First of all. I don't know how your A/V-Reciever works, but mine has only connectors with HDMI (and Komponent) for Video.
Second is, you asked about the Monitor description. I told you that it has native 1024x768 but it's a 16:9 TV. So I think it's easier to tell my Mediacanter it's connected to 16:9 TV and let the inernal scaler of the TV do his, insteaad of trying to tell vdr/MMS that 1024x768 Pixel is like 16:9

@agd5f

Seems Xorg is still taking data from EDID (even though I inserted the "IgnoreEdid" Option. But I'll do some further searching to fix that too.

Hello again,

I raelly tried guys. But I can't force xserver to take my modified Modelines. But I even get very few Info from both (card and TV).
So here's what I found out.

But when I restartet Xorg there was no change at all.

[Kano]

Then use vga port and native res, thats the most stupid thing to do when you use a higher res than native. It is impossible to get a good picture.

But when I restartet Xorg there was no change at all.

@Kano

If you watch my first post You'll see it's a Panasonic TH-42PV60E
Native Res. is 1024x768 .
At DVI or HDMI Inpput it only takes HD-Res. and scales them to 1024x768.

[Kano]

@batesman

basically no tv exists with a 1280x720 screen res, thats 720p, but the screen is more likely 1366x768, as you can not divide that res by 8 you have to use 1360x768 with a small black border. What's the name of your tv?

[batesman]

Ok, now it's getting clearer.
I hope I'll get some proper info's via "startx -logverbose 6".
I don't remember that I saw there much.
My failure was to think I should take a smaller resolution.
But the "movement" is done "within" the modeline.
I'll report later

[agd5f]

Google for "underscan modelines"

[batesman]

@ Kano

I did this already but the Tearing wasn't good at all (better but not good). I'g going to stay with the OSS drivers. There's no Tearing at all. Why is AMD/ATI not able to fix this ? I read in many forums about this.

@ agd5f

I tried to force a different res. but afterwards I got a black screen and had to reboot. For me it seems theat the TV needs a HD res.
I need a solution similar to what I made with fglrx

aticonfig --set-dispattrib=tdms2i,positionX:30 
aticonfig --set-dispattrib=tdms2i,positionY:15 
aticonfig --set-dispattrib=tdms2i,sizeX:1220 
aticonfig --set-dispattrib=tdms2i,sizeY:690

For me it looks like I sent 1280x780 res. but within the Desktop is 1220x690. On a "normal" TV it would like a 1280x720 screen with black borders.

After work I'll post some Xorg.logs
