Monitor's can be DANGEROUS!
We do not recommend that you open up the monitor yourself
as they contain extremely high voltages even when
turned off. Where appropriate take it to a qualified
monitor repair person.

Check to see that all the cables are connected and the
monitor is switched on. Check to see if any lights are active
on the monitor. If there are no lights on your monitor but
your computer is on then you could have a problem with your
If you have lights active on your monitor, then you may

B. The monitor's connection to the computer is damaged.
C. The monitor is faulty.
Best advice is to check the monitor, if possible on another
My monitor has a red, blue or green tinge
to the screen, Why?
Check the monitor's video lead plug which will have about
15 pins in it. If one of these pins is bent or broken, this
will cause the tinge on the screen. You can try and straighten
a bent pin but if it is physically broken then you wil have
to take it to a repair person.
Why is all the colour distorted on my monitor?
Open the Display Properties window by right clicking on your
desktop and then click properties. When the Display properties
box comes up, click settings. In the lower-left area of the
window, you can adjust your color settings. The High Color
or True Color option will give the most realistic images.
Remember, though, that color settings and resolution settings
go together, and some monitor/video card combinations cant
handle high settings in both areas.
My Monitor makes a clicking noise or flashes
sometimes when entering windows.
If the monitor only clicks or flashes when entering windows
or specific programs, the monitor is simply synchronizing
itself with the video, and there is nothing wrong with the
How do I change the resolution for my monitor?
If you right click on an empty area of your Desktop and
select properties. When the Display properties box comes up,
select settings. Go down to the slider in the screen area
and adjust your resolution accordingly. Select Apply and windows
will come up with a message asking you if you want to keep
this setting. Select yes, your screen may flicker while windows
adjusts settings. You will find that if you alter your resolution,
you may have to adjust your monitor picture using the horizontal/vertical
buttons on your screen.
How do I Connect Two Computers to One Monitor?
First of all you need to buy a switch box and a pair
of SVGA cables if they arent included with the switch
box you buy.
Shut down both computers
Connect the monitor to the switch box
Connect both computers to the switch box
Make sure all monitor plugs are screwed in properly and securely.
Turn on your monitor.
Reboot both computers
Turning the switch box control from A to B to make your different
computers appear on the monitor.
What resolution should I run my monitor at?
Although there are not really any definate rules what
resolution you should run your monitor at, the general guidelines
for easy readability are usually followed. See the
Most monitors will tend to run a resolution higher than mentioned
above, but bear in mind the size of the text.
eg: the higher the resolution the smaller the text.
What is the difference between an interlaced
and non-interlaced monitor ?
Interlaced CRTs are used for standard television displays.
In such a CRT, the electron gun first draws the odd numbered
lines from the top to the bottom of the screen, then comes
back to the top and draws the even numbered lines. While doing
so, the non-refreshed lines often fade before they are redrawn
resulting in flickering. In the non-interlaced mode, the screen
is drawn from top to bottom, line-by-line, which produces
less flicker and less eye strain for the user.
What should I consider when buying a
There are a number of factors to consider when buying
a new monitor. Your monitor may be the most expensive option
of a new computer system, and is the part that you will be
looking at most of the time, so it pays to get the right one
for your purposes.
Firstly and most importantly, you need to decide on how much
money you want to spend. Consider the size because once you've
got this great big monitor sat on your desk, how much room
is it going to take up? If desk space is limited, consider
buying a flat-screen monitor -remember that flat screen monitors
are more expensive than the average CRT monitors. Go to plenty
of outlets and view as many as you can before making a final
decision. You may also consider getting a cheaper deal by
buying online, especially if its the same model you have already
seen in the shop. (Don't forget that postage/shipping of monitors
can be expensive). Compare features such as antiglare coating,
digital controls, built-in microphone, built-in speakers or
somewhere to mount speakers, USB ports and ease of adjustment.
Compare warranties, as different monitors come with different
warranties. Some have been known to come with the standard
1 year warranty and others with as much as 5 years warranty.
(The general warranty being 3, with the manufacturer).
For typical home/small business use, specifications
are generally not of a great importance. Any name-brand
monitor sold by a reputable dealer will feature at
least the minimum specifications you need: .28 dot
pitch, SVGA, non-interlaced and capable of 1024x768
resolution. For gaming or working with graphics, look
for a monitor with a refresh rate of at least 75hz
at 1024x768 resolution. Also remember that actual
viewable size, which is measured diagonally, may compare
quite differently on monitors made by different manufacturers,
some might be slightly more generous with their viewable
area than others and give you a few more extra millimetres.
For example One monitor may have a viewable area of
15.1-inches and the other 16 inches. Not a great deal
you might think, but those extra couple of mm's can
make all the difference.
Can I use my television as a monitor?
There are plenty of video cards available nowadays
which will convert a VGA signal to one that is compatible
with your television set. Generally they have a TV
out socket on the videocard which enables you to plug
a composite out lead from your videocard into your
If your TV doesn't display more than 640x480 then
it's not really worth connecting if your intention
is to work at it, otherwise you might use it for games
or watching DVD's/Movies. Some of the more modern
TV's will actually display at 1024x768.
