5” HDMI Backpack display (w/ touch) doesn’t detect video signal

[noahc]

Hi,
I recently purchased the HDMI 5” touch display and found it doesn’t seem to display video or even detect a video output. I’ve tried it on both Windows and Mac with multiple HDMI cables. When plugged into power, the green power light lights up as expected and the touch capabilities work just fine. However i noticed the “video - good” light does nothing at all. Any help is appreciated

Have you been setting your resolution manually to 800x480? This screen requires that resolution be used.

Initially i thought it would auto-detect the resolution but upon not getting that to work, i went into my display adapter settings (on windows) and manually set it to 800x480 and still got no signal. I’m also concerned because I can’t seem to see any evidence that the backlight is running at all. When initially connected to power, the screen flashes white then seemingly the backlight turns off.

Does the same USB cable and port combo work for other devices and the HDMI cable works with other monitors?

Does 640x480 resolution partially work (eg. fills most of the screen width, but not entirely)?

Which version of Windows?

If non of the above helps lets swap it out (return / refund).
