But Pete (the OP), also stated on the 23rd that he booted up with :
"TuffTest Pro (http://www.tufftest.com/ttp01.htm) that is self-booting,
operating system independent and never goes anywhere near Windows". So
how can it be a Windows driver issue if the problem still exists without
Windows?

And it is converted to digital, to analog, and back partially into
digital (a mix of the two). Same thing happens when you plug into an
external LCD monitor as well. As the pixels live in a digital matrix,
while the contrast is controlled by analog means.

Ok the way to tell if its hardware or software causing the problem is when
the machine starts to boot drop into the BIOS whatever it is for your
laptop, F2 for Dells , Del for some others but anyway whatever it is for
your machine. If the problem is there in when you look in the BIOS its the
LCD panel or Cable or Motherboard port. IF it's not there then it's a
driver/application, error. Of course you could also connect it to an
external monitor and again if its there then its the grapghics card or
motherboard port or software/drivers and if its not there then it's the LCD
or cable

Actually the laptop belongs to my niece (or it did until recently when she
decided to get a new one and gave this one to me :o)) so I don't know what
it was declared as when new. When I look in Control Panel, there's a choice
of only two resolutions, 800x600 and 1024x768. There's a tick-box with the
words "Hide resolutions that this panel cannot display" (or something to
that effect) and there is currently a tick in that box. When I deselect that
choice, other resolutions become available, but selecting any of them makes
no change to the width of the display - that 65mm strip of "darkness" is
still there.

I tried a Linux LiveCD as you suggested Paul and there's no change, the
problem is still there - so it's hardware then. Oh dear :o(

Cheers mate,

Pete

Problem is though Barry, I've tried it outside of Windows as I explain above
(delineated with &&&&&). I also get the same result if I just go into the
BIOS at bootup or run a Linux LiveCD as suggested by Paul, so I'm
unfortunately resigned to it being an expensive hardware problem now. Thanks
anyway mate.

Pete

Thanks Fixer. The problem is still there when looking in the BIOS and even
when running a Linux LiveCD so it's not a Windows driver issue. The problem
is *NOT* there when viewing on an external monitor, so thanks to your
suggestions I'll try a new screen cable first as that's the cheapest :o)

Thanks mate,

Pete

Re: Acer Aspire 5630 Laptop screen/display problem

Can you post a screen shot of what the BIOS looks like?

Is there any chance that at some point someone replaced the LCD panel
with a different model?

You need to uninstall (if one is installed) the video driver
then reinstall it again. It may be found on Acer's site or
Intels. I'd go with Intel's since it is probably newer.
Appears to be Intel 950 video.

Because the driver is not working if present at all, you
won't have the 1280x800 resolution needed. It appears then
that what you see on the right side is simply 1280-1024=256
unused columns of pixels.

This is not proof it is hardware, the LiveCD may simply lack
support for the Intel GMA video it appears to use. The bios
is the wild-card, it should fill the whole screen but
because it doesn't offer the native resolution in windows
there does seem to be a driver problem.

One last thought, is it possible the screen on this laptop
has been replaced (presumably due to damage) with the wrong
one?

Becaues the display adapter isn't stretching non-native
resolutions to fill the entirety of the screen, instead it
is keeping the correct aspect ratio and upsampling.

It is not converted to analog and then back to digital. It
starts digital and stays digital to output to the LCD panel
built in, or is converted to analog for the output to an
external monitor.

PS, just flashed BIOS from V2.90 to 3.60 and VGA BIOS from Intel V1264 to
V1377 - but no different.

Re: Acer Aspire 5630 Laptop screen/display problem

Well, I take back what I said about it being a driver issue. It's
clearly a hardware issue. Any chance that it was flashed with the wrong
bios or that someone changed the LCD panel?

If you run the monitor info program here, without the external monitor
connected, and with just the internal LCD panel, does it say the
panel is 1280 x 800 ? An EDID might be a way for the laptop
manufacturer, to provide plug and play info about the panel,
its native size and resolutions. Not having an EDID on some
I2C bus, is not the end of the world, and is not a defect.

This article mentions that the BIOS can declare some info
about the panel, using an ACPI entry. The BIOS passes ACPI tables
to the operating system. You can look in Device Manager, or
alternately, use Everest Free Edition, to dump a text file
with a lot of that stuff.

I also noticed, when looking at the Intel driver on the
Acer 5630 download page (acer.co.uk), that it has an option
to define the resolution and refresh rate during installation.
Which is a pretty strange option to see. You'd think that
info would be fixed in some other way. Maybe it is for
development purposes or something, or used to override
some default ?

Are you saying the brightness and contrast (also gray scales) are
adjusted digitally? How can that be? As it is an analog voltage that
controls this on every pixel on a LCD screen.

Right Paul, we're getting into major stuff that I know nothing about here
mate :o)

Having run the moninfo program you mention above, there seems to be varying

they?) so I'll apologise now for making this post so long but I thought

Everest says that it doesn't fully support my chipset (Intel Calistoga
i945GM/PM) but it's probably just as well or there would be much more info
