Having display problems and not sure whats wrong, pls advise (kinda lengthy)

Okay approx 3 wks ago My monitor started doing some freaky things with no
known changes having been made to the system & no new drivers or anything.
Nothing new hardware wise, no magnetics in the area etc. Powering off the
monitor for a min or 2 and pwring back up image is perfect...for a few
minutes then starts flaking out again.

Things my system is doing:
a) Developed a bow in the image on the right hand side tht sometimes
increases in pitch then eases back (window edges are curved not straight)
b) Actually entire Desktop has a bow now, the black edge on the left is even
curved
c) Desktop image would slowly shift left about 1/4-1/2 " then do the same to
the right
e) Occationally the image actually squezes in a bit so that you have 1/4-1/2
" black edge to one side while the image is still alligned on the other.
f) certain of the OSD settings like Pin Ballence and such only seem to work
intermittantly
g) Then it decided a few times yesterday that after it got too bowed the
monitor went into standby mode and would only come back by repushing the
pwr button.

At the same time this all started I noticed the fan for my GF3 was
apparently dieing, removed it and replaced with another fan in case that was
the issue. I sent the monitor in to be checked as it was still under
warrenty and they ran it for 4 days and only prob they saw was the pin
ballence thing not working which a reset of the monitors memory seemed to
fix for them . While it was gone I used the Tvout on my card and never had
any image problems at all so since they couldn't get it to act up they sent
it back to me. Almost as soon as I hooked it up some of the very same things
came back to plauge me, including the issue of some of the OSD options
working intermittantly.

Things I've tried:
I've tried 2 other outlets for the monitors pwr in case it was a buggy
outlet but didnt seem to help.
I rechecked that there was nothing near the monitor that could cause mag
interferance
I have tried other pwr cables as well as using the same ones that worked at
hitachi
I made sure no other cables or wires are near the monitors cables
I have also pulled out fists full of hair trying to figure out whats wrong.
Ive removed and reseated the GRaphics card several times and its set a
factory default for mem and core clocks as it is an OCZ tweaked card I never
did oc it as its default is 215/515 to start with

Is it possible that BOTH have a problem that combined is makeing things
worse. Its odd that Hitachi said it never once did the image thing, that he
saw anyway, but the fact that the OSD's features are only working
intermittantly, which he did see once, and a reset of mem causes em to work
again for a bit would seem to me to imply that there is something wrong with
the monitor. As far as I understand things the OSD features are in the mon
hardware and wouldnt be affected by graphics card or drivers. Since hitachi
didnt seem to see the drift/image prob running at exact same Refersh rate
and Rez Im wondering if that is being caused by the graphics card and its a
combo problem.

Good news is that Hitachi will replace the monitor with a very similar
refurb since they discontinued my model if I wish and the ppl that supplied
my card seem willing to send a replacement to see if that helps but would
really appreciate some advise from a few Guru's especially if any of this
sounds familiar.

Any help or advise will be appreciated as Ive done a bunch of web searches
and I did find one fairly good mon troubleshooting page that described some
of the probs I have as being monitor low pwr supply issues but since Hitachi
didn't see it Im at a loss. I couldnt find any good descritions of graphic
card failure issues to compare mine to tho to see if it is just the card.

Should I bite the bullet and replace em both or does this problem sound
familar to someone out there.

Sincer Thanks
