What does resolution mean?
Resolution refers to the number of dots (consisting of 1 or more pixels)
displayed on the screen. The greater number of pixels displayed translates
into more information displayed on screen.
Why is the vertical refresh rate important?
The vertical refresh rate determines flicker - anything above 85Hz (Vesa
Standard) is considered flicker-free. The higher the vertical refresh
rates, the better. Please note that vertical refresh rates vary at different
resolutions, so check each manufacturers maximum refresh rates at
various resolutions when making a purchasing decision. LCD monitors do
not suffer from flicker we recommend you run them at the manufactuers
recommended refresh rate, this is typically 60Hz.
What is dot pitch and why is it important?
Dot pitch is the distance of one phosphor dot to the nearest dot of the
same color, on the adjacent line. The dot pitch determines the graininess
of the image on the screen - the lower (smaller) the dot pitch, the crisper
the image.
What is the difference between Aperture Grill and Invar
Shadow Mask technology?
Aperture Grill tubes use tiny vertical stripes of color the create the
images while Invar Shadow Mask technology uses tiny dots of light in a
heat resistant metal to create images. Hitachi monitors feature Invar
Shadow Mask technology because it provides a brighter, better picture
without the visible damper wire "shadow" lines across the screen
that Aperture Grill tubes frequently present. So, Hitachi monitors provide
crisper details for both text and graphics. See our section on how
monitors work.
My monitor does not display the resolution I want and
my monitor nominal says it supports this resolution. What's wrong?
First, check to ensure your computer video card supports these resolutions,
some cards have very specific frequency ranges and will not support lower
or higher resolution from what they consider the "normal" or
"optimal" range. While the monitor may support the resolution,
it is an output device and will run from the resolutions your computer
video card will allow. Second, ensure that you have used the correct resolution
on your video card and either the Hitachi or Microsoft standard drivers.

Are Hitachi monitors 110/220 volt switchable?
Yes, all current Hitachi monitors are 110/220 switchable and auto adjusting.
How should I clean my Hitachi monitor?
We suggest dampening a lint-free cloth with warm water and wiping the
monitor screen. Alternatively, special CRT screen cleaning solutions can
be purchased at most computer stores. Caution: do not use alcohol or ammonia
based products to clean your monitor screen, as this will damage the monitors
anti-glare coating.
Do your monitors ship with Mac adapters?
No. Most Mac systems no longer require adapters.
