Have you tried hdmi_edid_file as explained in previous posts? You also need to create the edid.dat file using tvservice.

Thanks for your info.
I have config.txt file already on my Pi. As I mentioned in my first post hdmi_force_hotplug=1 is already set in config.txt file.
But still have the same issue.
When I start my RPi with TV on all works great. Even if I later turn off Tv with RPi working I can turn on tv and all is working fine.
The only problem I have when I start my RPi with TV turn off and after that I turn my TV, TV doesn't recognize RPI.

Thanks,

Sorry, I misread your first post and thought you were looking for help editing your config.txt, a process which is not intuitive.

You definitely did it correctly with the remount command and everything (as outlined in those steps)? And the line that you added is not commented out with a "#" in front of it? I'm only asking because I encounter this exact problem every time I spin up a Raspberry Pi, and the hdmi_force_hotplug=1 setting fixes it each time.

Have you tried hdmi_edid_file as explained in previous posts? You also need to create the edid.dat file using tvservice.

should I follow those steps?

1. Delete 'hdmi_edid_file=1' from config.txt. If you have an empty edid.dat delete that as well.
2. Reboot with the tv on.
2. Run 'tvservice -m CEA' to see if it reads edid from TV correct and what is reported.
3. If everything seems ok, run 'tvservice -d'. Edid.dat will be placed in your home directory.
4. Move edid.dat from there to the correct location (not /boot on OE, probably /flash or something, cannot remember exactly).
5. After that, add 'hdmi_edid_file=1' to config.txt and reboot.

I wasn't sure if those steps are to help me with my issue?

Thanks,

@koze, yes sounds about right.

If you're using OpenELEC you'll need to move the file to /flash/edid.dat. Since /flash will be mounted read-only, you'll also need to remount the partition read-write, so step 4 should be:

Code:

mount -o remount,rw /flash
mv edid.dat /flash
sync
mount -o remount,ro /flash

I don't know if the above steps will help fix your problem, but it's probably worth a shot.

Run 'tvservice -m CEA' to see if it reads edid from TV correct and what is reported.

What should be returned to me to be sure that everthing seems to be ok?

That edit.dat file is located on my sd card. Am I right?

Thanks avp0 and MilhouseVH for your help.

Run 'tvservice -m CEA' to see if it reads edid from TV correct and what is reported.

You should get a list of modes supported by your display, with the preferred mode highlighted.

That edit.dat file is located on my sd card. Am I right?

That's where it needs to go, yes. Initially with "tvservice -d edid.dat" it will be written to your current directory, which is probably /storage.

After running following command:

tvservice -m CEA

I got following info:

Group CEA has 5 modes:
mode 1: 640x480 @ 60Hz 4:3, clock:25MHz progressive
mode 2: 720x480 @ 60Hz 4:3, clock:27MHz progressive
mode 3: 720x480 @ 60Hz 16:9, clock:27MHz progressive
(native) mode 4: 1280x720 @ 60Hz 16:9, clock:74MHz progressive
mode 5: 1920x1080 @ 60Hz 16:9, clock:74MHz interlaced

So it's look like RPi reads edid from TV correct. What above information means? Currently I am using mode 4 but I can switch to mode 5? Am I right?


After running following command:

tvservice -d

I got following info:

OpenELEC:~ # tvservice -d
tvservice: option requires an argument -- 'd'
Usage: tvservice [OPTION]...

-c, --sdtvon="MODE ASPECT" Power on SDTV with MODE (PAL or NTSC) and ASPECT (4:3 14:9 or 16:9)

I still couldn't locate edit.dat file on my RPi.


Do I need to run this commend to get edit.dat file :

tvservice -d edid.dat

?

Thank you,

Yes, sorry about that...

My guess from the above information is that your display has only a 1280x720 panel, which is its "native" resolution and what you should be using for XBMC. It appears your display may support 1920x1080 as an input resolution but the display will most likely re-scale it to 1280x720 to fit the native panel resolution, so 1920x1080 probably isn't a resolution/mode you want to use - stick with the native resolution (mode 4).

Thank you. What about edit.dat file:

[dandnsmith]

Yes, you need to do tvservice -d edid.dat, and place the file in /boot (for raspbmc).

You can analyse the result with edidparser edid.dat

[Milhouse]

Thank you. What about edit.dat file:

Yes, the command is:

Code:

tvservice -d edid.dat

[koze]

Here is what I've got:


I have checked and edit.dat was moved from my storage area to flash folder.

Analize command returned:


Can you please let me know if it was done correctly?



If everything is ok I will continue with:

5. After that, add 'hdmi_edid_file=1' to config.txt and reboot.



Thank you in advance,

koze

[Milhouse]

Can you please let me know if it was done correctly?

Looks fine to me.

Analize command returned:

As you've now moved the edid.dat file to /flash, the analyse command is:

Code:

edidparser /flash/edid.dat

Anyway try updating your config.txt and see if it has any effect.

[koze]

works great,
