HDMI Output from PC


#1

I know several other threads have gone over this but I haven’t gotten any of them to fix it.

I always see LVDS connected but HDMI disconnected:

Lakka:~ # for p in /sys/class/drm/*/status; do con=${p%/status}; echo -n "${con#
*/card?-}: "; cat $p; done
DVI-D-1: disconnected
HDMI-A-1: disconnected
LVDS-1: connected
VGA-1: disconnected

Is this the right place to put the video= line? I tried only either of the two line I have there in addition to both.

savefile_directory = "~/savefiles"
savestate_directory = "~/savestates"
input_remapping_directory = "~/remappings"
playlist_directory = "~/playlists"
libretro_directory = "/tmp/cores"
libretro_info_path = "/tmp/cores"
system_directory = "~/system"
rgui_browser_directory = "~/roms"
assets_directory = "/tmp/assets"
thumbnails_directory = "~/thumbnails"
rgui_show_start_screen = "false"
**video = "LVDS-1:d"**
**    video = "HDMI-A-1:e"**
video_fullscreen = "true"
video_windowed_fullscreen = "false"
video_threaded = "true"
video_smooth = "false"
video_aspect_ratio_auto = "true"
video_shader_dir = "/tmp/shaders"

Here is video card log I can get the verbose if it is really needed:

Lakka:~ # lspci -nnk | grep -A 3 VGA

Any thoughts on this or anything I should try to give you guys more information as to what the problem is? When I go to change the Video Index from the UI I only am able to change between 0 and 1 (I saw some people mentionding 4-5 options). Let me know if there is anything I can do to help you help me!


#3

It looks like it’s not seeing anything connected to the HDMI port. I don’t really know what to tell you there. That’s a pretty fundamental issue.


#4

Is there a way I can troubleshoot the HDMI port more?

I used the cable to connect a windows computer to my TV and that worked so it isn’t the cable.


#5

Hi, I read your post trying to find out why I couldn’t get my HDMI port to work. I am using a laptop with two grapichs cards. I had to disable hybrid mode and the integrated graphics card and that did the trick.


#6

some hdmi “cables” are not bi-directional (PASSIVE VS ACTIVE HDMI CABLES), so try to insert the end connected to the monitor/tv in the cOmputer and vice versa.


#7

@jdaming can you try to boot with

live video=LVDS-1:d video=HDMI-A-1:e

You should not have this setting in RetroArch configuration file.

Also please provide some Lakka system logs.

Thank you.

@jcam79 I tried switching the cable and got nothing. I tried using it with another windows computer and it displayed fine on the tv. I don’t think it is the cable.

@KimFant The computer is a HP Compaq 8710W it does have a NVID IA graphics card but it doesn’t appear as if it has onboard graphic or anything that might be getting in the way. I checked BIOS for settings like this and couldn’t find any either.

@gouchi Not sure exactly what you mean by “boot with”. I tried placing the line in the config file (I know you said not to but it was about all I knew how to do) and it was removed every time I rebooted the system. How do I boot with that command? Is the log below enough? Is there a different log you need?

@jdaming sorry I meant in the boot prompt to make a test if you are using live usb, try to enter

live video=LVDS-1:d video=HDMI-A-1:e

It will boot in live mode, disable the PC screen and enable HDMI.

If you still have HDMI display try to edit RetroArch configuration file and change the option to video_monitor_index = "1"

Thank you.


#10

I have never used live usb before. My laptop boots straight into retroarch. I can access the command line (via putty/ssh) and edit the config but I have never gotten to a command prompt where I could start retroarch like that. I didn’t find a whole lot of into on Live USB sounds like a totally different install method than I have used.

Is that the same as switching the index in the video tab of the configuration settings? I did it anyway through the config file and still no change.


#11

Try to boot with usb stick and enter in the boot prompt live video=LVDS-1:d video=HDMI-A-1:e

You can use etcher to burn the image to usb stick.
