Hello, same problem installation v7.0.1 in RPI4 and no video signal. I have a signal if I start by disconnecting HDMI cable and then connecting it.

With rpi3 v7.1.1 it works fine with my TV, kodi has no problem, but with rpi4 there seems to be no solution to black screen in kodi.

Hello everyone. I think the problem is with the resolution of my monitor 1366x768, with version 7.0.1 it did not start or Recalbox (black screen)
With version 7.1 and 7.1.1 Recalbox starts in 1080p but when switching to kodi black screen
I already tried adding with config.txt:
hdmi_group = 2
hdmi_mode = 39
and Recalbox boots at 1360x768, but kodi doesn't get it
Thanks to who can help

@zamalek89 Try to enter kodi:

• While in Recalbox, disconnect the HDMI cable.
• Press X to enter kodi.
• Wait a moment for it to enter kodi.
• Connect the HDMI cable
  Not a solution, but it works

@zamalek89 I have been able to start Recalbox on a 1366x768 monitor in the following way:
You put the microSD into the PC, open the "recalbox" unit, you will find several files, edit "config.txt" (notepad works).
You change the lines:
#hdmi_group = 1
#hdmi_mode = 1
by:
hdmi_group = 2
hdmi_mode = 39
and save modifications. With these changes, it will start in 1360x768 resolution and recalbox will work without a problem, the bad thing is that you will not be able to switch to kodi, you will get a black screen.
I have tried modifying kodi.videomode in the "recalbox.conf" file but have not succeeded in getting it into kodi.
** important ** that configuration only works for that monitor, if you start with that configuration on any TV it will not work

@Pitch64 It seems that way, my problem is that I give it two uses: in a room with a 22 "monitor for me and in the living room with the TV to play the children ..., I won't be able to use the pi4 for me. Thank you for your support

@Laban Thanks for your answer
I have tried winSCP and PuTTy over SSH and it throws the same error

I can't find the directory you mention to me

@Zing thanks for your answer, but i still have the same problem.
On a new Pi 3 Mod. B + installation with v7.0.1 (for pi3) no problem. Boots without modifying config.txt in DMT 81 (preferred resolution).
In a new Pi 4 installation with v7.0.1 (for pi4) the intro videos are seen, then black screen.

I can't get it to boot into DMT by modifying config.txt
hdmi_group = 2
hdmi_mode = 81
I only get it to boot by forcing VGA with hdmi_safe = 1 or with hdmi_group = 1
hdmi_group = x
I've tried different HDMI cables in case it was a cable problem.

I have not tried to criticize the work of Recalbox, in any case it is always appreciated its great effort and dedication.
The problem is that an error like this in the update means the total loss of the same and a total lack of knowledge if there may be more problems for subsequent updates.

@oyyodams thanks for the reply, but it would be better if a stable update did not come out if it is not
