Does that work for any of you ? Or is there any way to change the video output ?
On my side, it doesn’t with two different monitors : they state that the range is too high, although their specifications go up to 75Hz vertical refresh rate. And I also tried with two different adapters I use for the same purpose on two Rpi3.
If I could get that to work, it would mean we could reuse a bunch of still working monitors and replace the aging boxes with a number of VIMs.
Many thanks in advance
EDIT : more debug details that I should have included in this initial post.
The two different monitors I tried display the following error messages :
I use a 1440*900@75hz with a HDMI to DVI adapter. Works without problem with android and libreelec. Didn’t try ubuntu though. Only thing is I don’t have sound with this adapter, but it’s OK for testing.
Thanks for letting me know. I actually wish I had taken more time to test that display configuration on Android before erasing it to replace it with Linux. In the long term that’s the platform I want to be in, but in the mean time it could have yielded some useful information.
Anyway, from your experience at least I know that the same resolution at the same frequency works with DVI ; perhaps there is less overhead for the adapter’s processor to ‘translate’ to a digital format than to VGA’s analog one ? If so, scaling down the initial output received from the VIM might make things better ?
EDIT : the Hyundai monitor actually has a DVI connector as well, I just remembered, so building on your experience, I’ve just bought online an HDMI to DVI cable and will report back my findings ; regarding the sound, as for you, its absence is not critical and may anyway be worked around using the bluetooth channel. Thanks again
How about support 800*480 resolution over HDMI in android? Is it real? I wanna use khadas vim board in my car pc project. I must compile own kernel with custom resolution and timings settings?
