Resolution output incorrect - Smiggel - 15th Feb, 2013 07:29 AM

Hi,

I have Xbian installed since yesterday and am having issues with the output resolution.

On my Philips (don't know the model by head) tv Xbian looks good with the resolution 1280 x 768. So far so good. However, as soon as I reboot the Pi, the resolution is screwed. Somehow I get an output that looks like 4:3.

I have to go to the settings then where I can see my resolution is set to 1280 x 768. There I have to switch to for example to 1280 x 720. As soon as I get the message if I want to keep this resolution I say no and then the screen pops back to 1280 x 768 and works fine again.

This also happens in 1.0 #5

Anyone else having this problem? This issue is not happening when I use RaspBMC.

Best regards.

You could try to set the resolution in the config.txt of your raspberry via the "hdmi_mode" parameter:
/boot/config.txt
http://elinux.org/RPiconfig

There is a list of available resolutions about in the middle of the site.

Thanks, will look into that.

No luck at all. Go's all fine during boot, but as soon as XBMC is being displayed, it go's wrong. Always the wrong resolution, even if I set it in the config.txt.

I guess that the preferred resolution for the tv is: 1280x768p. It's not a normal resolution and somehow XBMC can not display that on boot? If i set it by had in the settings menu, it works fine. But as soon as I reboot, it go's wrong again.

Found this when I executed the commants that look for the specs in the tv:

HDMI:EDID found preferred DMT detail timing format: 1280x768p @ 60 Hz (22)

Even if I set hdmi_group=2 and hdmi_mode=22 I get a screen looking like 4:3. :-s It's just not displaying correctly.

what TV or screen you using ?

RE: Resolution output incorrect - Smiggel - 16th Feb, 2013 01:21 AM

It's a Philips 32PF5331/12 Widescreen tv. Not to new anymore. ;-)

The strange thing is, that I can see that XBMC has the preferred resolution of 1280x768p in it's list. When I boot the pi, XBMC is set on that value as I can see in the system settings. However, it's just not show that way on the tv. :-s When I switch resolution to something else and then back to 1280x768 it looks fine. :-)

Can it have something to do with drivers? When I whipe my SD card and install RaspBMC, I don't seem to have this issue. However, I rather use Xbian.

RE: Resolution output incorrect - rikardo1979 - 16th Feb, 2013 02:19 AM

did u try add

Code:

hdmi_ignore_edid=0xa5000080

also try to remove

Code:

disable_overscan=1

Hmmm. I can try that later with the other settings together. Maybe that will help.

I did try it with hdmi_edid_file=1 enabled, but that did not help either.

I will later you know later if it helped or not. Put my daughter in front of the tv for a moment now. :-)

Code:

disable_overscan=1

is not in my config.

No luck either. Going out of my mind here. :-) Really have no clue of what is going on here. Really strange.

Got it now with help from rikardo1979. This is my config:

arm_freq=840
core_freq=375
gpu_mem_256=100
gpu_mem_512=100
sdram_freq=400
over_voltage=0
overscan=1

Seems like the problem was the overscan=1 that was not in my config. :-)
