It sounds as though Adobe Gamma isn't functional. That setting should
blank out your screen.

I'm still unsure of what you mean by "inconsistent". Do you mean that
colors on one part of the screen appear differently than the same color on
other parts, or that they're generally "off" in comparison to the CRT?

I would begin by trying to establish whether that video chip is compatible
with external gamma controls, and if so, how to enable them (It may be a
BIOS setting). It may also have an internal gamma control that could get
you closer to a useful color balance.

Yes, I noticed that on Acer's site. Even though the monitor has a wide
stated angle of viewing (170º) and high contrast ratio, it is still
described as an "office monitor". That moniker is typically used to
describe less flexible models, but that wouldn't explain the basic
difficulty that you're having getting it into the ballpark using either an
internal gamma control (if one exists for that video chip) or Adobe Gamma.

Nor do I. The salient message above is that "Mpl.dll is not a valid Win32
application". This suggests that the driver software is fundamentally
incompatible with your system, and there won't be much you can do about
that. If it were me, the Monaco would be returned without further ado.

I hope you're able to sort it all out.
