I am connecting monitor via 2 adapters VGA-to-DVI and then DVI-to-HDMI to my RPI v3. I've been using it in such manner on and off for a couple of years now and it always worked. After several months of pause I tried to power it up again and now I get no HDMI output. The power adapter is 2.5Amp. The card is obviously works, because I can connect via RealVNC. All other functions (WiFi, etc.) seems to be working.
Naturally I thought there might be a problem with my monitor, so I connected it to a working computer and I can see it's OK. Also I tried another monitor connecting to PI and same - no output.
Interestingly enough, apparently PI can properly detect which monitor is currently connected to HDMI port, as you can see on the screenshots of RealVNC Connection Property using 2 different monitors. The field "size" showing the correct maximum resolution supporting by each monitor, so at least some communication via HDMI port is functioning properly.
What can I do?
