I hope i can ask a simple question here....

If i have my video output set to 1024x768 and set the overscan/underscan to fill the screen, and then set the pixel ratio to 1.25....

The video files, pictures, DVD's and whatever will not look stretched.... is this true?

The Reason i ask is i have got it set that way and everything looks okay, it just means that i am missing some horizontal lines of resolution right?

I've read this whole thread, and quite a bit of the other thread, and a ton of information all over, and this is still quite greek to me.

I have noticed that since i'm going hdmi-> receiver->hdmi->tv that the edids getting passed around are different than when i do hdmi->tv. Pretty sure if i end up with a totally screwy setting the receiver will come back with unsupported tv mode and just not do it.

so yah, not too worried about twiddling; clearly this isn't the simplest thing to setup.

Never mind, I figured it out Smile

When you've set up multiple resolutions in the xorg , but they don't appear in the resolutions menu in systems/video output in XBMC , is that correct, or should they appear there?

I'm pretty sure everything is set up correct in the xorg, but somehow, I can not select the resolutions I made:

I'm a n00b to XBMC and have been trying to set up a Revo 3610 with XBMC Live. It's (mostly) working fine, but I can't get a 1080p signal. I've tried all sorts of different configurations in my xorg.conf as well as the suggestions in this thread but a lot of them result in be being asked for a username or password when XBMC boots up or I get a black screen.

I tried running the instructions for all the EDID stuff, but am getting messages like this under many of the results:

Code:

(WW) Jan 08 12:46:24 NVIDIA(0):     EDID are not allowed.

I have the Revo hooked up to a Sony AV amp via HDMI which then passes through the signal to the screen. This resulted in the same error as above so I tried wiring it straight to the TV but this didn't make a difference.

I have a 50" Panasonic plasma (TH-50PZ70) that supports 1920x1080 at 50 and 60hz and in theory can handle 24fps as well as it complies with the pulldown specs for this.

Can anyone help at all? I know nothing about Ubuntu at all apart from what I have learned from reading this forum and other sources on the internet, although the last few days have been a very steep learning curve for me! Confused

- idlehands - 2010-01-11

I think I sorted out picking the correct modes. I was about to really dig in and work on fixing overscan with the modline, however I noticed that i could fix overscan in xbmc 9.11 with the video calibration screen.
Is there some benefit to fixing overscan with those options vs manually brute forcing it with the modelines?

Since my television manual only lists 1080i @60hz and 720p@60hz as supported having settings to handle 720p and 1080p@60, 50 and 24 don't seem like something I have to bother swizzling with.

I added modelines because even though I run a minimal system I do things other than XBMC. I use Chromium and some games. All run really nice on a minimal system. Smile

Hi there, i'm trying to get 1360x768 using HDMI cable but i can't get it working; using VGA cable it works nicely. With previous computer and using the same TV i was using 1360x768 using DVI to HDMI cable and it worked fine, but now, with this nVidia ION chip i can't get that res... any advice or tip to solve this issue??

many thanks in advance, regards,

Before I mess things up changing my xorg I thought I'd ask here first.

I have a Panasonic P46G10 plasma (european model) and with the default XBMC Live install (9.11) it does not do 1080p (1080i works fine). Am I correct in thinking I have to edit xorg in order to achieve 1080p?

I have XBMC connected like this:
XBMC (GF GT220) -> HDMI -> Receiver -> HDMI -> TV.

Would it be best if I connected my XBMC directly to the TV via HDMI (bypassing the receiver) before performing the actions in the OP?

Thanks & best regards!

- SubSense - 2010-01-24

Okay, read the thread. I'm using a Panasonic Plasma TH-42PV70FA HD ready. Max 1080i.
In my live installation also the xorg.conf was missing. Editing the XF86Config instead doesn't work. After a reboot the wil is reset. Downloading a fresh CD now.

I'm trying to achieve 720p @ 24Hz but I don't know if that's even possible.
From the panasonic site I've learned that only 50 Hz and 60 Hz are supported. But when I look up the specs of a 1080p model it states also these two resolutions.

So is 720p @ 24 Hz possible on a HD ready TV?

- Khakzoy - 2010-01-25

Ok, I used this guide to get 1080P @ 24Hz on my Asrock ION 330.

It works great with HD content but now I run into trouble playing DVD content.

From what I understand I can add "Modes" under the subsection "Display". For now I only added one with the name "1920x1080". The name I use for the modeline has to match the name I specified under "modes"

Am I free to use whatever name I want or does it have to match with the name from the EDID info?

I want to add "1920x1080@60hz" to see if I can fix the judder on DVD playback.

Guys,
In general, read this thread as well : http://forum.xbmc.org/showthread.php?tid=64412

Apples, I have a 50V10.. Your G should be basically the same. That means the first post's settings in the above thread should work for you. But remember the "modes" fix in http://forum.xbmc.org/showpost.php?p=482375&postcount=52 otherwise some "p" content will be "i".
.. And you should really generate G10-specific modelines to be safe. Good luck with that, I kept getting conflicting results.

This post http://forum.xbmc.org/showpost.php?p=464287&postcount=2 has xorg settings that will use edid to set refresh rate. It should work if your TV obeys the standards.

- luthan - 2010-01-28

when i add these two lines into xorg.conf and reboot the pc i get nothing:
Option "ExactModeTimingsDVI" "TRUE"
Option "ModeValidation" "NoEdidModes"

should these be removed after doing the test?

also, my tv is 720p panasonic and it seems that all the modes that seem like they should be fine are rejected, i dont see one mode 1280x720 that is accepted

what am i doing wrong?

- SteveGo - 2010-01-29

Alright, I need some help. So apparently my TV doesn't support EDID, at least over HDMI. It's a Pioneer 1366x768 plasma, model PDP-5080HD.

What can I do to get modelines and then force them to be an option under resolution?

I'm pretty sure this tv accepts 1920x1080 input (24, 50, and 60 Hz), and I've tried putting those in my xorg.conf file, but they never show available. The only one that ever shows up is 1920x1080@50, as the fullscreen option. Along with a bunch of lower res "default" options.

- finite3 - 2010-01-30

a) read the first post in this thread, it tells you what to do
b) google is your friend. try searching for "modeline" and your tv model
c) check the mythtv modeline database
d) here is an xorg.conf that may work. it has every res in it. or there is a slight chance it will break your tv - which is why you should try the above steps first.

Are you responding to me? If so, I already tried the instructions in the first post and like I said, my TV doesn't support EDID, so it doesn't report back the valid resolutions.

Believe me, I've googled and there are no modelines for my tv in the database or otherwise.
