Projecting the Right Image
own a digital projector and use it with my laptop to give
presentations. I'm almost at the point of giving up because of my
inability to get a decent image from the projector on the screen. How do I match the laptop's output to that of the projector
so what I see on one screen appears on the other? Is there an order in which I change brightness or

can be tricky customers and it is important to bear in mind their many
limitations, compared with other types of display device. Also, unless it is a
fixed installation you are always going to have to contend with variables that
you have little or no control over, such as ambient lighting conditions, screen
distance and position and so on.
not much you can do about the image coming out of your laptop, except to make
sure that the display matches the projector’s ‘native’ resolution.
making adjustments to the projector it is important to wait for at least ten
minutes after switching it on, to allow the temperature of the lamp and other
key components to stabilise. If you don’t you can easily end up chasing your
tail, trying to compensate for changes in brightness and colour temperature
that occur during the warm-up phase. You should also check the ‘age’ of your
projector lamp; as they reach the end of their working lives the light output
and colour characteristics can start to change.
best way to set up a projector is to use specialised test patterns.
Professional calibrated pattern generators are very expensive but you can get
good results using test patterns recorded on DVD or created using PC software.
The DVD of the Disney Pixar movie ‘The Incredibles’ includes a set of
test patterns called the THX
Optimizer for adjusting brightness and contrast. For a more comprehensive
set of patterns have a look at the DVD Video CD Reference Suite from IT Works (http://www.itworks.com/products/DVDref-suite.htm).
Parting is Such Sweet Sorrow
I have just bought a new computer and I would like to have
two separate partitions on the HDD, one for Windows 98 and all my old software,
and another for Windows XP or Vista. I seem to remember reading somewhere
that this can be difficult. Can you advise please?

or splitting a hard disc drive into two or more ‘virtual’ drives is best
carried out before any operating systems (OS) are installed. This is especially
true of a dual boot (or multi-boot) setup, but in any case the oldest version
of Windows (i.e. Windows 98) should always be installed first. You will also
have to use the FAT32 filing system for the Windows 98 partition, and NTFS for
XP and Vista.
can be done retrospectively on a drive that already has an operating system
installed using specialist utilities like Partition Magic but I advise against
it. It’s far better to wipe the drive and start from scratch by creating
partitions using the utility on the Windows XP installation disc.
Printing from Web Pages
am trying to print off one specific item from a web page, or even one single
page of a website, but I end up with all of the pages. If I try to highlight
the bit I want everything is highlighted so everything is printed. How can I
get it to restrict the printing to what I need and thus save time, paper and

Internet Explorer can print individual ‘frames’ on a web
page and this option is normally selected by default (File > Print >
Options tab), however, not all web sites use frames, so it’s largely academic.
You should be able to select any part of a web page using your mouse but it
needs a steady hand. I find it easiest to click the mouse at the end or bottom
right hand corner of the part I want to highlight then click, hold and slowly
drag the mouse pointer to the start of the section. Incidentally, if you are
finding it difficult to control the mouse precisely try reducing its
sensitivity by going to Start > Control Panel > Mouse and select the
Pointer Options tab.
Once you have highlighted the part you want to print right
click on it and select Copy (or press Ctrl + C). Now open a blank Word
document, right click to create an insertion point then select Paste (or press
Ctrl + V) and print the document as normal. If you want to capture an image
from a web page just right-click on it, select Save Picture As navigate to the
folder where you want it to be stored and click Save.
Emailing Video Clips
I have some video
Clips from my Nikon Coolpix camera that I want to e-mail to a friend but so far
I have failed to find a means of doing this successfully. Am I doing
something wrong or is it just not possible to do it? Just clicking on them
and then e-mail doesn't work - and yes, I'm not terribly computer literate I'm

clips have to be sent as ‘attachments’ to your emails. Compose your email then
click on the Attachment icon on the message box toolbar. In the dialogue box
that opens locate your video clip file, select it, click the Attach button then
Send the message as normal.
