Hi all.
I've had this Viewsonic P95f+b since February. I'm very pleased with the
quality of it (It just takes a bit of tweaking of the convergence and
brightness/contrast to get it just right). However, here's the problem. When
I run at 1024x768 @ 75hz, I start getting jitter every now and again. I've
eliminated possible sources of EMI in the room it's in, but i've noticed
something. I believe my kitchen is on the same circuit as my bedroom (where
my computer is). Now, whenever the tea kettle or some other high power using
device is turned on, I start to get jitter. Sometimes it's less predictable
(I think the furnace may be causing it sometimes). Upping the refresh rate
to 85hz causes it to go away 99.9% of the time.. only on the rare occassion,
when a lot of things are using power in my house, will that jitter a bit. So
to you electronic types out there, does this sound like it could be solved
with a voltage regulator/line conditoner? or should I just keep it at 85hz
refresh and ignore 75hz. I kinda like 75hz because the text seems to be a
bit clearer on this model. Also, is it a possible problem with the monitor?
It's still under warranty, but i'm sorta thinking its not. I took it to the
shop where I bought it, and where I know the technicians quite well. They
left it plugged in for 8 hours in the store and didn't experience any jitter
at 75hz. Any suggestions or possible solutions would be appreciated!
