How to get Kodi to display on waveshare 5" lcd in retropie?

TwoGuidosGaming

I installed kodi via the experimental menu, How can I enable it to display on my 5" waveshare lcd? I get a white screen after launching. Works fine if I hook it up to the hdmi tv directly. Thanks for any help.

Which model ? There are diferent 5'' ones. Did you adjusted config.txt accordingly ? If yes, post your config.txt. Waveshare screens will only work with Kodi 16.

waveshare 5" is 800x480, not in the official cea/dmt mode list so custom cvt is needed;

in /boot/config.txt try

hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0

The thing is that there are an USB connection version and a GPIO (?) version.
For the USB ones, something like you posted should be enough. For example for the 7'' USB one, this is confirmed to be working:

hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt 1024 600 60 6 0 0 0

For the GPIOs versions, I don't know, but it is very likely that you will need to install the provided drivers, or try to use a generic LCD overlay.

yeah he has the gpio/hdmi 5" version, just trying to help him get his display sorted. that's hdmi. touch screen I have no idea, that's where the drivers come in, I don't use them.

btw, waveshare 5"/7" are all hdmi screens, the touch overlays for 5" screens can be either gpio or usb, the 7" ones are all usb.

Yes, that's it. At least the image should work.
Besides your config.txt settings, I recommend confirming that he is running Kodi 16, and also that the power supply is enough for both the Pi and the LCD. If not sure try with a separete power supply for the LCD and another for the Pi.

Well I think I have everything setup correctly..I'm getting video to the LCD when I start a enumerator..plying games fine. Just when I click on kodi I lose video..how do I know what version of kodi I am running? Edit I'm at work but my config is what you posted. Using 5v 2.5amp ps

@TwoGuidosGaming I don't know what are the right overlay settings for that particular LCD, you have to experiment with it.
But the first thing I would do is to start with a clean config.txt, without overclocking, and only add the settings senkun posted. Than I would try with a PSU also for the LCD. I think that should make it work. And make sure you are using Kodi 16, check in Kodi -> System Information.
