Like with many things, the size of screen you choose will be at least
somewhat influenced by your personal taste. Having said that, using a
screen that is simply too large for the viewing room is one of the most
common and easy-to-make mistakes made in home theatre design.
We'd like to sell you the largest screen you need but we also want you
to be happy with it so please read on to see if we can help you choose
a screen size that will suit you best.
A very good starting point for screen size is a screen with a width
roughly one half of the viewing distance.
Although this flies in the face of the "if some is good, more is
better" philosophy - here are a number of reasons why it might be a
idea to buy less from us!
Your picture can look better
Sitting too close to an
enlarged digital image is going to make visual artefacts look very
obvious. e.g. the "screen door" effect on low resolution
projectors, compression artefacts from poorly authored DVDs, "stair
stepping" on strong diagonal lines etc... Putting a little
distance between you and the image can put these minor blemishes back
into perspective and keep you watching the show instead of
concentrating on the visual distortions.
It’s easier to watch
Too big a picture will simply be
uncomfortable to watch over time. It might seem ok, even
impressive for short periods but after a couple of hours of moving your
eyes back and forth it can become very tiring. An
appropriately-sized picture will still be visually impressive and yet
you’ll be able to watch the whole show in comfort.
It will help your projector
As image size increases, image
brightness decreases rapidly. By controlling your screen size
to an appropriate level, you can be assured that you’re not trading off
too much of your projector’s brightness to achieve a good
picture. Reducing your screen size to an appropriate level
can let you use a lower lamp power setting (if your projector supports
such a mode) and save you money.
Whilst we're on the subject of positioning screens, try to have their
viewing height such that your viewers eyes have to look no more than 15
degrees from horizontal to gaze upon the centre
of the screen. Forcing viewers to look upwards or downwards to focus on
the centre of your screen
will become tiresome over time and degrade the viewing experience.
It (possibly) goes without saying your screen should also be positioned
to minimise ambient light falling upon
it. This light will 'wash out' your picture rapidly as the supposedly
'dark' areas of the displayed image
become inadvertently illuminated by your window/door/fishtank etc.
Darker is better with projected images.
