Hello, I have the same monitor! It may be for
"Factory Testing"! My unit is pinkish, but works
fine otherwise! Anyone know what's common?
VP 463 video drive ic? Rono.

I have a Viesonic PS790 monitor On the base of the mainboard in the
rear is a 4 pin plug like the audio plug used to connect CD-ROM audio
to motherboard. It is hidden behind a small breakout in the shell. I am
curious as to what it is.
Is it a serial link for uploading firmware? If anyone knows please let
me know.
