Prevention of Blue Screen
Hi Folks, I have purchased a 12V video monitor (Wilmaxit) which works really well but keeps going to blue screen when the input signal gets too poor. Is there a simple inexpensive way of stopping this ? Thanks in anticipation.

Re: Prevention of Blue Screen
There some simple circuits which simply add a small pulse to the video input in the absence of syncs that trick the monitor into thinking there are syncs present.
I haven't looked but i'm guessing they will be in the Wiki somewhere.
Or you might have a poke about with a scope to see if it can be disabled inside the monitor.

I bought one of these recently, although it worked, the through video quality seem bandwidth reduced. The device's OSG were sharp but the through video wasn't. I tried to update the firmware, which resulted in bricking the deviceg8vpg wrote: ↑Sat Feb 16, 2019 10:59 amIts all in the Wiki here;

Are there any dedicated circuits that will do the job? The Syncsmurf 5 is too expensive for such a simple purpose IMO, it's cheaper to just buy a new monitor...
