HDMI xsever settings are wrong for my 720P Vizo TV.

This looks to be how to set that up, you will have to try different values to see what works.


I have an idea and I wanted to see if you guys think its worth trying. I saw a viewport switch in xrandr man. I thought maybe make a viewport a little larger than the desktop. I am thinking when I scroll to the edge of the desktop then the desktop would extend to the edge of the screen.
What do you guys think and if so then how do I set this up?

This looks to be how to set that up, you will have to try different values to see what works.

Also, one option that might also be worth looking at is underscan/overscan. I wonder if this might be useful to adjust things by just that little bit that would be over/under the size of the monitor?
No clue if this would actually be helpful or not, to be honest.

I just found this: Version 1.4 adds an optional Border property.

• An optional Border property. This property allows a client to
specify that the viewport of the CRTC is smaller than the active
display region described its mode. This is useful, for example,
for compensating for the overscan behavior of certain
televisions.

Now to figure out how to use this.

Doesn’t seem to work.

I found this web page: http://filthypants.blogspot.com/2013...el-hd4000.html

I found this on that page:The name of the person that made the following post was not available on the above listed web page.

The option that worked for me is --transform, which performs some crazy matrix math that I don't understand (I'll update this post if someone tells me wtf is going on) on each pixel, apparently kinda like the pixel shader stuff I've written about elsewhere, I think...? Anyway (replace HDMI3 with whatever your device is called)

I tried that:

steve7233@steve7233-HP-Pavilion-dv6-Notebook-PC:~$ xrandr --output HMI1 --transform 1.05,-35,0,1.05,-19,-0,0,1
xrandr: failed to parse '1.05,-35,0,1.05,-19,-0,0,1' as a transformation

xrandr --output H[COLOR=#ff0000][B]D[/B][/COLOR]MI1 --transform 1.05,-35,0,1.05,-19,-0,0,1

Looks like you left out the 'D' in HDMI1

Looks like I will be stuck using the tv's VGA port until I can buy a 1080p since this 720p seems unable to work right with Ubuntu. I guess Ubuntu isn't as good as the devs would like us to think since other distro's apparently can handle VIZO 720p tv's better. O well there still seems to be more good things in Ubuntu than bad. I figure so long as I can get KDE with Ubuntu then I can handle a few incompatibility’s. I thought Saucy might do it finally since Percise and the others couldn't. Maybe the next version will in a few months or when ever it gets done.

I wanted to use a frustrated emote so you would understand my meaning but there doesn’t seem to be one. I wonder if bang head would work.

[oshunluvr]

I would agree with you there. I spent months trying to get Kubuntu to work with my plasma TV correctly - even writing my own custom modelines. Then I booted up Sabayon and it worked right out of the box. A while later, Ubuntu worked (10.10 I think) but Kubuntu did not.

At this point, I had given up so I never figured out why Ubuntu worked but Kubuntu did not. You might boot Ubuntu and see if it works. You can always add KDE to Ubuntu.

[claydoh]

head-desk is definitely appropriate.

However, if there is a distro out there that has an xorg that works well with a 1366x768 TV, by all means give it a try
I would have hoped that this would have been improved since I was in your exact shoes back in 2011. Ubuntu was the only one I could get to even come close once I used the correct radeon/radeonHD/fglrx driver and using a modeline I had found almost accidentally during one of many search trawlings.

When I had to move in early 2012, I made to decision to sell my Vizio and replace it with a 23 inch monitor partly for this problem, even though I had solved it, as I had to leave my PC behind.

[steve7233]

How do I get /usr/bin/gnome-display-properties? I want to see if using gnome will set the display properly. Maybe KDE doesn’t
understand. If this theory is true then maybe the KDE devs should be told so they can check into it.

[claydoh]

It is part of gnome-control-center so you would have to install that package to get it.

I am going to give my best guess that this is using the same under-the-hood tools to get its information from that Kubuntu does, ie xorg, the intel driver, xrandr, etc. If xorg and/or the video driver can't output this properly, the desktop environment tools used likely won't make a difference.

[steve7233]

Now I have a Samsung 1080 that I got from my sister. No manual. Saucy selected 1080i. I have the same problem as the other tv. Desktop larger than screen.

[steve7233]

Never mind. I had to reboot and now it displays correctly. Weird because I plugged in the HDMI before I booted the first time. Must have been a strange glitch. Now I can play my Civilization 5 games at 1920 x 1080 resolution! To bad the sound stills comes out of my laptop speakers. I wish it came out of the TV speakers like KDE does. That seems to Fireaxis fault not saucy's.

So 720p TVs don't display right in Kubuntu but 1080p tvs do

[steve7233]

I think its because I switched to the HDMI2/DVI port on the TV and renamed it to PC. I probably just forgot to reboot. Now when I go into the TV menu it says HDMI2 is set to wide PC. HDMI one doesn’t seem to have a wide PC setting.
