Hello, I have a laptop without hdmi. Currently, I use lubuntu 16.04 and, I have installed KODI. My laptop doesnt have hdmi but, it has DVI and then, I connect the laptop to the HDMI of the television through an adapter, DVI to HDMI. It works very well, i can see lubuntu and kodi in the TV and, I can disable lapto's screen and, I only use the tv like primary screen. Everything works.
The problem is when I try use libreelec.
When I try use libreelec, I cant disable the primary screen, which is laptop's screen and I cant use chromium for libreelec, for example. because chromium open in laptop. Another problem is, when I choose video through DVI and I choose resolution ( I choose 1080p) There is no signal in my TV 4k but, If I use another monitor whose maximum resolution is 1080p, there is signal. In lubuntu, in resolution 1080p, i have signal in mi tv 4k. I dont know why, with libreelec, i have no signal.
I think if I am able to choose TV like primary screen and disable laptop's screen, it could work, but i dont know how to disable.
Anyone have any idea? Sorry for my bad english. And thank you for everything.
