2005FPW better thru VGA than DVI?

[Guest]

Archived from groups: alt.sys.pc-clone.dell (More info?)

My setup: Precision M70 laptop with 1680x1050 native screen; D-Port dock;
2005FPW monitor connected to the D-Port.

Thinking it should give the best quality, I connected the 2005FPW to the
D-Port using the DVI cable, since the monitor's native resolution is
1680x1050, the same as the laptop.

I found the annoying effect that single columns of white pixels between
black would have a pronounced red tinge. This was expecially noticable
with small bold text like in Outlook or Outlook Express message lists,
with words like "fill" in the bold subject of an unread message.

Looking at the laptop screen when undocked, the effect is less so, but
still detectable.

I have a 1704FP on another computer, and single columns of white pixels
are nice and crisp. This is on a Dell Dimension about 6 years old, and
is connected using the VGA interface.

So I then tried connecting the 2005FPW monitor to the D-Port using the
VGA instead of the DVI, and was amazed to find the effect vastly reduced,
possibly even gone. The display had little if any colour fringing.

I'm not familiar with the techniclities of DVI, so I'd be grateful for
any comments on the above, or suggestions. Does it suggest any part of
the system might be faulty?

Cheers

Some people attribute this red tinge to having ClearType enabled. There is
a free utility out there called ClearTweak that is supposed to help get rid
of that.

I used to have this problem on one of my LCD monitors. My problem seemed to
be with the automatic adjustment feature of the LCD. The solution was to
temporarily change my desktop bitmap to a calibration bitmap for my screen
resolution that I found online so it has nice edges to work with, then do
the automatic adjustment.

Bill,

Thanks for the reply....

Ah, so I'm not the only one who has experienced this effect then!

I saw something about ClearType and ClearTweak on the Microsoft site the
other day. I'll visit there again and try it out.

When running in DVI mode, there doesn't appear to be the facility or the
need for Auto Adjust, as I believe the pixels are addressed directly.
I assume that is how ClearType works, by using sub-pixel addressing.
Auto adjustment seems to be more to do with the monitor synchronising
its pixel boundaries with the analogue video input via VGA.

The ClearTweak angle sounds worth pursuing - thanks for the pointer!

Cheers
