Struggling to configure about display-switch HOT 7 CLOSED

And just like that, setting Monitor 2 to "Hdmi1" has done the trick - which is odd, since there isn't a single mention of Hdmi1 in the logs!

Thanks for your help @haimgel - from my side the issue is closed; let me know if my updated configs, logs, etc. would be of help in any way.

Hmm... I don't have a good suggestion here, other than the following:

1. Please update to 1.0 (I just merged it) from 0.3.0. There are some improvements in there w.r.t. retrying failed DDC/CI transactions, which might help.

2. You did not specify the OS on both machines: is it Windows, Mac, or Linux? This could be important, especially if we get more reports like yours.

Thanks for the reply - it's been a while since I've submitted any kind of bug report, so I've left out the most basic thing! I'm running Windows 10 20H2, build 19042.985, and the 0.3.0 build was compiled from source.

I've upgraded to the pre-built binaries on my desktop and I'm getting the following output:

I've also ordered a USB-C to DisplayPort cable I plan to test once it arrives.

Thanks.

OK, so I think the issue is that your monitor_id values are empty, so these match anything, and could be the reason monitors "alternate" as you say. The app detects 4 monitors, and with these empty monitor_id values, it switches all four, to both values, one after another (in your first log). Also, since you only have 2 monitors connected, I'd say the error about Svideo input is not important. I'd suggest trying with this config:

[monitor1]
monitor_id = "#1"
on_usb_connect = 0xf

[monitor2]
monitor_id = "#2"
on_usb_connect = 0x110f

See if Generic PnP Monitor #1 and ... #2 are indeed the two you need to switch, and if not, adjust monitor_id values to match other monitors as reported by the app. It matches by a substring.

P.S.: Configuration parser in the app should ideally balk on such a config, and not do a stupid confusing thing above... So this is something I'd try to fix.

Thanks for the reply. I've updated my config and will give it a whirl in the morning once my work laptop goes on - thanks for the help! It might be a really simple tool, but if I get this working as it's intended, then it's a massive productivity aid. Thank you!

Right, some progress. Monitor 1 (my 32") seems to be switching fine - monitor 2 (the 24") seems to want to stay on my laptop at all times. It turns off each time I press the switch, but very shortly after loads up my laptop (which one a DP input). I've also swapped my DisplayPort lead to a USB-C -> DisplayPort lead, since I didn't have enough bandwidth to run 2 high resolution monitors on a single USB-C link.

I've tried cycling through #2, #3# and #4 with no success... not quite sure where to go from here.

I'd say, if ithe second monitor does not switch, then probably the on_usb_connect = 0xf0f setting is incorrect (but you can confirm in the logs what exactly does it say). I'd start by using some known-good values, e.g. DP, HDMI1, etc., and see if that works.

Another avenue to explore would be to try some other DDC/CI controlling software and try switching with that (sorry I cannot recommend anything on windows specifically). This way you'd know if this is some kind of misconfiguration or an issue with your hardware specifically... Some monitors have a buggy or incomplete DDC/CI implementations.
