Strip Down Guide for BenQ 28" VA Monitor GC2870H
-
Thanks for your help. I use the same model :BenQGC2870H. I would like to combine a solution where i have a minimum power consumption and fast without osd message boot.

@adrien Hi Adrien, that was my initial plan but I use the two relays now for my speakers to avoid the initial crack sound when powering on the amplifier und I use one relay for the monitor power supply and one for the amplifier.
-
@yep_dd Hello, and thanks for your guide :) Did you try to do it ? do you confirm that could work ? Thanks
-
@Adrien No problem, I am pretty sure it should work but I have not tried it. I might in the future. I am working on a few other bugifxes as well (amplifier only turns on when sound is played and stuff like that). I also suggest to use the microwave / radar sensor instead of the PIR. it is much cleaner and can go behind the mirror.
Regarding the OSD, instead of cutting wires to the backlight this seems like a valuable option. At the moment I can’t try this (I need a friend to help me take down the mirror as it is too heavy), but I will tomorrow: https://www.youtube.com/watch?v=y86AXOZwlgU (TL;DW: press menu button while turning monitor on and disable logo)

Interesting solution this is the hidden menu of the display. The problem is the boot time i feel like it takes a long time to boot no ? well i will also try to cut the wire if it doesn’t work properly i will solder them. About the microwave sensor i have a rcwl0516 to test but the problem is the range of detection it detect people from a very large range
-
@Adrien ah, okay I see… yes that might be a problem in my case it works just fine. I will see about the boot time tomorrow.
-
@adrien Okay, so it is about 3 seconds boot time I am estimating. No logo anymore. Just the annoying “HDMI1” screen on the lower right. Let’s see if that satisfies me or I will cut the wires as well. Have you tried yet?
-
@yep_dd You could use relay with a small delay to power your backlight. So the screen will only be visible after the “HDMI1” box disappeared. Personally I wouldn’t bother with it, though.
-
@yep_dd I have not yet try, i will do my test as soon as i receive my mirror, but 3 secs look not too long
-
@madscientist okay, so after a couple of days I am absolutely satisfied. I turn on my monitor with a small httpserver python script whenever someone is at home and -if it is night- any HUE light is on. I am now thinking of changing this to different energy saving modes in my magicmirror:
- Always On
- On when someone is home
- On when someone is home and any light is on (turns off at night)
- Only on when activated by PIR / Radar Sensor
