HDMI out screen size problem

[hatalar205]

Hi. I bought a new Toshiba Portege M800-107 with vista preinstalled. After a week I installed Ubuntu 8.10 and later 9.04 Jauntry. Everything works perfect. But I have a problem with HDMI out. When I tried to connect 42' LCDTV unfortunately I have a resolution problem. The output of the computer doesn't fit properly to the TV. It is a bit larger than TV's screen.I mean I can hardly see the half of the top and button panels.I have looked everywhere for solution but I couldn't find anything.

So I installed Sabayon but the problem is same.
Just because this annoying problem I have to use vista (which I hate more than anything in the world). Even this message is being written in vista. I write three times in ubuntu forums unfortunately nobody answered. So I see that there are a lot of people who have same problem and who haven't been answered yet like me.

I think the problem is TV's perfect resolution is 1280 X 720 and 60 refresh rate. But computer's is 1680 x 800. The same problem solved under Vista with a screen cropper tool. Is there any solution in Sabayon?
My Video Card is Intel® GMA 4500MHD.

Thanks in advance.

Okay it should be simple enough even though I have not tried it for similar screen it worked for other screens and config's.

Edit /etc/X11/xorg.conf and add the 1280x720 to it as highest resolution should look like this below , note below replaced 1024x768 as default and would be too big for your screen.
"1280x720" " 1024x600" "800x600"

1216x684 might end up being the closest to 1280x720 just check in windows for the resized size that fits properly.

Can also search for 720i and 1080i that translates into numbering like this and use that as it is a format / size range in it's own not really pc standard sizes.

1 Tv of mine is 1080i 1920x1080 but because of reading that small letters I have to have 1260x704 and the other typing on now is 1216x664 for perfect fit or there about's.

You would have to play around with this even edit grub.conf to have vga=791 this should work and say " res=1216x664 " and if all goes well it should default to this and be limited to this as max size.
So have both grub.conf and xorg.conf to have these sizes applicable to your screen and you should have success.

Almost did not answer when I saw Ubuntu.

You could use the gtf command to find a Modeline:

Code: Select all

acertm8215 fitzcarraldo # gtf 1280 720 60

  # 1280x720 @ 60.00 Hz (GTF) hsync: 44.76 kHz; pclk: 74.48 MHz
  Modeline "1280x720_60.00"  74.48  1280 1336 1472 1664  720 721 724 746  -HSync +Vsync

acertm8215 fitzcarraldo #

and then edit /etc/X11/xorg.conf to add the Modeline. The following thread gives a good explanation of what to do, and would be worth trying: how to get widescreen (1280x768) working on linux?

Here's another thread that might be of help: [mythtv-users] xorg.conf for 1280x720 HDTV

There's also a utility in Portage and Entropy called xvidtune:

so you could install that and try it out:

Code: Select all

acertm8215 fitzcarraldo # equo install xvidtune

or, if you're a Portage user:

Code: Select all

acertm8215 fitzcarraldo # emerge xvidtune

I did but nothing changed unfortunately.

Sorry for that. I just want to show I looked for and tried several possible solutions but couldn't find anything.

I did but nothing changed. I read that link but something strange with my xorg.conf file. There is only one "monitor" and "screen" part nothimg more. I mean at least there must be two (hdmi+laptop's screen)

so you could install that and try it out:
Code: Select all
acertm8215 fitzcarraldo # equo install xvidtune
or, if you're a Portage user:
Code: Select all
acertm8215 fitzcarraldo # emerge xvidtune

I also installed that program. It has lots of Wanings about its danger. So I didn't do much with it.

Here is my xorg.conf file. Maybe you can look at this. And if possible someone can post his or her xorg.conf file.

Thanks in advance. I want to solve this new laptop's problem before its becoming an old one.

you said you tried changing the resolution in the xorg.conf to whatever and nothing happened.
Did you restart X? or the computer?
If you did and still nothing happened I noticed that the Mode line is commented out with the "#" in front.
you could try removing that.

Also, did you try changing your resolution via the nvidia settings manager?

Code: Select all

nvidia-settings

Yes, I did. I mean I restarted my computer again. But, nothing happened.

And as I have said earlier above, my video card is not nvidia but intel

You can have a look at this link as they also had HDTV issues and looks like they figured it out.

http://www.nvnews.net/vbulletin/archive ... 71175.html

Option "TVStandard" "HD720p" #or NTSC etc

http://ubuntuforums.org/showthread.php?p=7139018

Just check what yours can do as you have to keep in mind both i and p versions and even with p you have (1080p24, 1080p25, 1080p30, 1080p50, 1080p60) and likely it is not compatible with the screen you have or have to tweak them to get best results wiht the video card you have.
Nvidia only implemented close to the 7800 or later HDTV compatible hardware / drivers but the card if different might still be able to drive the resolutions to 1920x1080 or beyond , have to check up on this before trying to over-extend it.

If the screen / tv works with directv they have ippi 480i 480p 720p 1080i 1080p depending on the receiver so check on it what works and then try the same in xorg.conf .

If you have success post it as I am still trying to get the best config for the ones I have as well. "panasonic" "sansui"
MMMhhh I might be able to get the config from a mythboontu and post here think it was working correctly in there.
