Hi all,

I have a DELL Precision 670 that came with 2001FP
later I upgraded the Video Card to EVGA 7800GTX KO.

Now I ordered an additional monitor 2005FPW but suddenly :)
I wonder if my new monitor arrives I can setup the resolution for
both monitors separately ... I hope so!

Thanks in advance,
Best Regards,
Giovanni
 
Yes, but the native resolution for both panels is 1600x1200 isn't it? They
will only operate well using their native resolution.

I'm sorry but the 2005FPW doesn't even support 1600x1200, where did you
get that info?

You are forgiven,
mine works great @ 1024x768@75Hz ...
you only get 60Hz @ 1680x1050

Hz is meaningless on an LCD panel. You could set it for 12 and it would
look and work the same.

not really, while it doesn't effect the flicker on the
screen, there is still the issue of what the LCD actually
supports. Often that's 60 or 75, maybe a littl more, and
nothing else.

True. I was using exaggeration to make the point that any supported value
works the same.
 
I've tried it both ways and it seems to make little difference. I leave
it on digital but have an old flat screen on the analog connection as
well...

The reason I ask is because you said it runs fine at 1024x768@75Hz,
and I've seen some people say that they are unable to configure the
refresh rate to 75Hz over DVI at lower resolutions, and others say that
they are able to force 75Hz over DVI at lower resolutions. I'd be
interested to know what video card you are using and what you did to
achieve 75Hz.

But why? On a FP, 60 and 75 will make no difference
 
The lower refresh rates are at the higher resolutions. I believe it
drops down to 60Hz only at the second higher resolution above the one I
selected...

I'm using the standard ATI RADEON X300 that comes with the base X400

Hope this helps,
Vinnie

I haven't convinced myself that that applies to fast paced gaming and all FPs.
A FP doesn't have phosphors that need refreshing, so there is no need to
maintain some minimum refresh rate for purposes of reducing flicker. But
AFAIK, with both analog and DVI connections, the selected refresh rate
corresponds to the rate at which the contents of the frame buffer is sent to the
display; at 60Hz you are sending 60 updates/sec, at 75Hz you are sending 75,
etc. I suspect that faster rates might have some benefits... reduced tearing in
some situations, higher frame rates with vsync enabled, lower latencies and
smoother performance which is perceptible to some people, that sort of thing.
Assuming there is some truth to this, there would still be the question of what
the user's panel supports. Externally supporting 75Hz frame rates is one thing,
internally supporting it is another. There is the question of pixel response times
and resolution (bandwidth) and possibly other things I'm not aware of.

I'm not a hardcore gamer and I don't have the gear to research the subject
for myself, but I have stumbled across various discussions in gaming forums
where people have stated that they achieved better performance with 75Hz
vs 60Hz on FPs. Maybe it is a placebo effect, maybe not.
 
All I know is @ 60Hz my ATI TV Wonder Card flickers and @ 75Hz it doesn't...

Just to clarify, I take it you mean that when watching TV on your LCD monitor
via your ATI TV Wonder you perceive flickering in the rendered video if the
monitor refresh rate is @ 60Hz but you don't if it is @ 75Hz? I take it you
see this behavior on both of your LCDs?

In any case, I knew I should have said "no need to maintain some minimum
refresh rate for purposes of reducing THAT KIND OF flicker". There are
different types/causes of flicker. I don't know what is causing what you
describe, but back when I first read about it, I was surprised to learn that
LCD displays have their own types of flickering problems. One of the LCD
test pages I bookmarked:

http://www.techmind.org/lcd/

talks a bit about it and has some static(!) test screens. Oddly enough, the
only test which appears to produce what I'd call flicker on my 2001FP is
the first row-inversion test, and it sounds as though that shouldn't produce
a positive on desktop LCDs. A desktop replacement with 20.1" and a
traditional keyboard would be sweet :-)
