knobs each have a specific purpose. Two of them are used for
focusing, one for vertical focus, and one for horizontal focus.
third, voltage, regulates how much power is fed to the monitor.
This can adjust how bright or dim the monitor is. Though it
may help very dim monitors, in most cases it gives the whole
display a more washed out look. Gamma control is a better idea
for lightening up your monitor. In dire situations, this can
be adjusted slightly to get a more visible picture.
your monitor on, and let it boot into your OS. Find a resolution
that you would like to use, find some small text that appears
blurry. (Note: this will not fix haziness caused by low refresh
rates. If that is the case, a new monitor or video card would
be needed to fix the situation). Carefully, make sure not to
touch any of the electronic cables or inside of the monitor,
adjust each of the focus knobs until the text becomes crisp.
Start with one focus knob until you see the vertical lines come
into focus, before you continue with the second knob. After
the monitor is focused to your liking, power it down and make
sure it is unplugged from the wall. As long as the monitor is
plugged into the wall, power runs from the socket up to the
monitor's power-supply. Potentially giving the monitor power,
even though it is turned off. Using super-glue, or modeling
cement, carefully place a little bit around each knob to ensure
the settings are not disrupted. Give the glue adequate time
to dry before continuing.
a precautionary measure, you may want to blow the dust off of
the monitor components before you close it up. This will prevent
any electronic failures due to dust build-up. This can be done
with compressed air cans, found easily at any office supply
store. Do not use any household fans or hair dryers, as it could
be possible for them to cause internal damage to the monitor.
Finally, replace the monitor casing and secure it tightly with
its original screws. Plug it back into the wall, and power it
back on. That once old, hazy monitor, once again has a nice
note that even when the monitor is off, as well as unplugged
there is still enormous amounts of voltage in the power supply.
Depending on the monitor, it can get up to 25000 voltes. Which
is more than enough to deliver a lethal shock.
