DisplayLink chip and external TV tuner

AlbanRampon · 04-23-2017, 04:51 PM

Hello GTM,

Thank you for the logs.
Windows indicates that there is one ACER P221 monitor connected at 1680x1050.
The following article I found online claims the max resolution of the Box 9 is 1280x1024.

Do you use two monitors simultaneously on this machine?
Can you check which resolution the box expects and which resolution is in the Display settings menu?

I don't see the EDID file from the monitor in the logs and USB errors are filling the logs so I don't see what resolution the dock is actually sending.
Seeing a partial display would fit with having the tuner video mixer not being to able to cope with the resolution.

Kind regards,
Alban

I'm only using one monitor - the Acer P221W.

If I set the resolution from the Windows desktop (right-click --> Display settings --> Advanced display settings --> Resolution) to 1280 x 1024, and then set the TV tuner box resolution to the same 1280 x 1024 resolution (using its on-screen configuration menu), I get essentially the same results that I've been getting: in 'full-screen TV' mode the entire TV video signal is perfectly visible (as it should be), but in 'window TV' mode I see almost the entire PC video signal (a bit of the bottom is truncated) - more than when the resolution of the TV tuner and the resolution set in Windows matched - but NO TV SIGNAL AT ALL, and after a few seconds in 'window TV' mode the TV tuner box reverts back to 'full-screen TV' mode on its own.

Should I be concerned about USB errors filling the logs? What are these errors? It seems important that you can't see what resolution the UD-3900 is sending.

What about the lack of the EDID file from the monitor: is that a concern? Why is it missing? I'm using a 3rd-party DVI-to-VGA adapter that I purchased, instead of the DVI-to-VGA adapter that was shipped with the UD-3900. I believe I've tried both, but I can retry the one that was shipped with the UD-3900 if you think that could matter.

What about the driver for the UD-3900: am I using the most recent version? Could that matter in this case?
