So I am having an issue with connection my Pi4 to my Samsung TV. The TV is a Samsung QN55Q6DTAFXZA. On the Pi I have connected the Micro HDMI port 0 (closest to the USB C) to the TV however I am unable to get it to display on the TV. When I check the log on the TV it says "CEC Command, Source enabled" but I still get no video. I have confirmed both the port on the Pi and the cable are good by plugging it into an HP monitor that I have. I was able able to get video working to the TV via HDMI port 1 however it was running at a fairly low resolution with a bit of lag and no audio (which is expected on the second HDMI port as I understand it).
I've played with the setting in the config.txt to no avail (safe mode, hdmi boost set to 7, hotplug 1) . At this point I have reverted back to the default setting in config.txt and decided to see if folks on here have any idea.
Try adding this to
config.txtwhen using the first HDMI port:
hdmi_ignore_cec=1 hdmi_group=1 hdmi_mode=16

Disable safe mode and try tweaking these values, it will be trail and error till you find the right combo:
hdmi_force_hotplug=1 ..... HDMI output mode will be used, even if no monitor is detected
hdmi_ignore_edid=0xa5000080 ...... enables the ignoring of EDID/display data
config_hdmi_boost=7 ...... signal strength of the HDMI interface, possible values are 0 to 11
hdmi_group=2 ..... '2' is DMT
hdmi_mode=16 ....... '16' is 1024x768___60Hz___4:3
disable_overscan=0 ...... use default value of overscans
overscan_left=0 ...... the number of pixels to add left / right / etc ...

@mitu Thanks, that appears to have worked! Now the fun of getting SM64 to run smoothly.
