Hi All,

I am running a home built PC with an Intel Motherboard using the 82865G
on board graphics controller. I have recently acquired a Goodmans
GTV27W3LCD TV/Monitor which is attached via the 15 Pin VGA port to the

The PC is running Windows XP Pro (SP2) with current updates (at time of

May problem is with the resolution. I cannot set it any higher than
800x600. Under Display Properties > Settings I have three Screen
Resolution options:


If I use anything other than 800x600 any text is pretty much illegible.
Also, when changing the resolution the monitor still displays 800x600
in green text at the bottom right of the screen.

Does anyone have one of these displays and have it working at the
higher resolutions?

Any help appreciated.

A review I found, lists native resolution as 1280x720. This is a one
page review for your monitor.


There is a page with resolution options for 865G. And 1280x720
is one of the modes.


So the question would be, why is the monitor not happy with that
resolution ? Have you set the refresh rate to 60Hz (the LCD should
like that) ? It sounds like the monitor is not autodetecting the
signal coming from the PC properly. Illegible text could be a
sign of downsampling, and downsampling is used at non-native
resolutions. If your computer successfully achieves 1280x720
res, the text should be sharp, as no downsampling is used inside
the LCD monitor.


Re: Widescreen Monitor with Windows XP Pro

Thanks for the reply. Actually, if I set the PC higher than 800x600 I
can only select 60Hz. Now, only just noticed this but if I set the PC
to 1280x720 then the Monitor displays 960x720. Cable issue maybe?

Interesting. So both resolutions as seen at the monitor, are 4:3
ones. It seems to be refusing to do any 16:9 ones.

Is the image fully displayed in both 960x720 and 800x600 ?
Not clipped or anything.

Some built-in graphics chips have a pan mode, where the
full screen might be X*Y, and only a smaller x*y portion
is visible. Moving the mouse causes the screen to pan to
the appropriate section. It is like a permanent zoom function.
Yours probably isn't doing that.

I see mention in one posting in Google, that increasing the
video RAM setting in the BIOS, helps with the higher resolutions.
Again, seems unlikely, but go into your BIOS and bump it to
the max.

You would think the driver/control panel would only display
the resolutions that could be supported under the existing
conditions. So you select 1280x720 and 960x720 is displayed
on the monitor ?

I'm trying to think through, whether there is any way to
figure out whether the monitor or the computer are not telling
the truth. The monitor uses a hardware function to measure
the input signal. I suppose the firmware and controller in
the monitor can mess up the result. But I'm thinking right
now, that the problem is with the 865G. And it is always
possible for a driver to do one thing, and report something
else to the OS or to any third party tools or utilities.

Any possibility to test the monitor on another computer ?

This is a pretty expensive experiment, but I wonder if booting
a Knoppix CD would shine any light on the problem. Knoppix
(knopper.net) is a read-only OS that needs no hard drive. You
insert the CD and boot the machine, and viola, you are running
Linux. Knoppix can be downloaded from knopper.net (from a mirror
listed on the download page), and it is 700MB, a huge download.
Not a candidate for dialup.

With a Knoppix CD, the CD boots quickly to a command prompt.

You type: knoppix screen=1280x1024

to force the resolution at boot time for the Xwindows display system.
At the final stages of booting, one of the last steps is changing
from some lower resolution, to the user specified value.

If you have ADSL or cable, and have a CD burner, this will take
you about an hour to prepare. I had to get a better burner, to
make a 700MB CD.

Your phone company would probably hang up your phone line, if you
tried to download 700MB at 5KB/sec via dialup :-)


Re: Widescreen Monitor with Windows XP Pro

I had a similar problem to you, and i had to change my graphics
card and use a dvi cable I would say the problem is your on board
graphics controller

How old is you motherboard?

Re: Widescreen Monitor with Windows XP Pro

I was beginning to wonder if I needed to change the graphics card. The
LCD TV/Monitor doesn't have a DVI input though,only 15 pin VGA.

This is the motherboard I am using:

Out of interest, are you using the same Monitor and what graphics card
did you get?

While I could not find an online version of the manual to download,
it seems another product from goodmans.co.uk has the option to
switch between 4:3 and 16:9. Have you checked the onscreen
menu for such a setting ? It could be that the monitor is messing
this up! Check the menu. See if there is a way to change the monitor
to 16:9 mode. Then maybe you'll get native mode 1280 x 720.


Re: Widescreen Monitor with Windows XP Pro

There isn't an option per se that I can find. There is an Image Size
option which, when using PC Input allows:

1) Fill All
2) Fill 1:1
3) Fill Aspect

When using the Tuner (using the set as a TV) you get:

1) Fill All
2) Zoom
3) Letterbox
4) Subtitles
5) Normal
6) 14:9
7) Auto

I have tried all three options on the PC Input.

Thanks for keeping up with this though. I'm going to try the Live CD
you mentioned probably tomorrow now.

Actually, the reason I headed over to the Goodmans site, is I was
looking for the Monitor INF and ICM. I remember having a problem here,
getting resolutions like 1280x1024. My memory is fuzzy, but I think things
finally worked properly after the INF for my LCD monitor was installed.
(ICM is something to do with color calibration or color profiles,
something like that.)

Of course Goodmans has no downloads as such, so you'd need to figure
out who made the monitor for them.


Here is another weird one:

("Monitor driver", AFAIK, refers to the ICM file...)

Here is an example of what Goodmans should provide for your PC. For
my LCD, these files didn't come on a floppy or anything. I had to
download them, but they weren't that hard to find (10 minutes work).
You can open the INF with Notepad, as the INF is a text file.


For your 865G, you could also go to downloadfinder.intel.com and see
if there is a more recent driver for the build-in graphics.

Re: Widescreen Monitor with Windows XP Pro

I just tried the Knoppix CD.

During initial boot the display reads 640x480
If I type in: Knoppix Screen=1280x1024 (as instructed) the monitor will
display "Out of range"
If I type in: Knoppix Screen=1280x720 the monitor displays 1024x768
during the startup sequence.
Once X-Windows loads the monitor displays 800x600.

At this point I can Pan horizontally and vertically with the mouse.

I have the most current Intel graphics drivers installed.

I found an interesting article here. Basically it claims there
can be some difficulties expressing 16:9 formats in the monitor EDID
information. But 1280 x 720 should not be causing a problem though,
as 1280 is divisible by 8.


Some geeky crap follows, which you can ignore if you want.
Skip to after this section if you want...

You can use Knoppix to get the raw 128 byte EDID from the monitor.
This is the recipe I just tried.

1) load this in the web browser that appears on the Knoppix desktop.
   There may be a more recent version than this, and this is
   the first one I could find.


   Select Save To Disk when prompted. The file will go into your home

2) Open a terminal session. That is the icon on the bar at the bottom, with
   a monitor icon and the ">" in one corner. You will already be pointed to
   your home directory. The web browser will dump the file in that home

3) Type these commands in the terminal session:

   gzip -c -d read-edid.tar.gz | tar xf -
   cd read-edid-1.3.2
   sudo ./get-edid | ./parse-edid
   sudo ./get-edid > my_edid

   The first command unzips the files and puts them in a directory.
   The second command places you in the new directory.
   The third command compiles the programs.
   The fourth command executes them. Two programs are used, and one
   program is "piped" to the other. The sudo option in front of the
   command, gives the get-edid program "root" permissions, so the
   hardware in the computer can be accessed. Parse-Edid should show
   the maximum resolution.
   The fifth command places the 128 bytes of info from the monitor,
   into the file "my_edid".

4) You can insert a floppy into your floppy drive. There should be
   a floppy icon in the upper right of the Knoppix desktop. _Only_
   click the icon when a floppy is placed in the drive, not before.
   Clicking the floppy icon does a Unix mount command. Knoppix will
   read a goodly portion of the floppy, before drawing a graphical
   picture of what files are on the floppy.

   There is a file icon on the lower desktop bar as well. Clicking one of
   those (don't remember which one, and I'm back in Windows right now)
   will open a picture of your home directory. (Could be the "home"
   icon.) Drag and drop the "my_edid" file from your home directory
   to the floppy. A popup menu will immediately appear, so do this
   slowly and carefully. Don't move the mouse until you see the menu.
   Then select "copy" from the menu. Now your edid info is on the floppy.

   To be useful, the floppy should be in an MSDOS format, such as
   you get by formatting the floppy in Windows. Knoppix should be
   able to deal with the floppy in that state. Don't try formatting
   the floppy in Knoppix (just a PITA).

   Once copied, "close" the floppy window. _Wait_ up to 30 seconds
   for any Knoppix file system accesses to the floppy to stop. Then
   pop out the floppy. Now you can shut down Knoppix if you want.

5) Back in Windows, you can open the 128 byte file using a hex editor.
   There is a free hex editor here. I use version 2.3 and I cannot
   tell what version is currently being offered.


   You can wipe over the Hex Editor screen display and copy the
   hexidecimal representation of the data. Paste into your news
   reader and edit as appropriate.

   An alternative to this, would be to use the Unix "strings" command,
   and get a hex dump of the file that way. "man strings" would give
   the options, and you'd want whatever option dumps hex. It could
   be something like "strings -x my_edid > my_edid.txt" or
   "strings -x my_edid" to see the hex dump on the terminal session

This is my EDID. NEC 1765 monitor (4:3 aspect ratio, native 1280x1024)

Grabbing bytes 38 thru 53, gives 8 pairs of bytes.
Only the first two pairs contain intelligence.
Even though my monitor supports other resolutions,
these are the ones listed.

71 4f (7*16+1=113, *8=904, +248=1152), 4:3 aspect, lower bits 0f=15, +60=75Hz
81 80 (8*16+1=129, *8=1032, +248=1280), 5:4 aspect, lower bits 00=0, +60=60Hz
01 01 (six times) - likely meaning these bytes are unused.

The "71 4f" pair says 1152x864 at 75Hz. The "81 80" pair says 1280x1024 60Hz.

I found this on the Microsoft page. If the EDID is
bad, then Windows will likely not be paying any
attention. The EDID could also be incorrect in some
way (such as not specifying 16:9 in byte 39).
One way to fix this, is to get the "monitor driver"
file, but since Goodmans offers no downloads, you're
screwed on that possibility. The monitor driver file
tells Windows the max res, which you hope would be
1280x7820 60Hz or whatever.

"Unable to Select a Higher Screen Area in Display Properties"

While Powerstrip is mentioned as a way to fix it (in the
Wikipedia article), Powerstrip works best with ATI and Nvidia
video cards. The author of Powerstrip has not programmed it for
chips like 865G. I expect Nvidia and ATI may have adhered to
some standard for the necessary registers, making it easier to
write Powerstrip for those standalone video cards.

Thanks for all this. I have made a little bit of progress.

I installed Powerstrip and configured it to read data directly from the
monitor. I then created a custom driver using this data. Once I loaded
the driver I can now successfully select 1024x768. However, I still get
the same problem when I select anything higher than that.

Re: Widescreen Monitor with Windows XP Pro

Update on this. It looks like the monitor is actually faulty. All of a
sudden it started cycling between all of the inputs; Tuner, Scart1,
Scart2, PC etc. I've tried leaving it powered off for a couple of hours
but after switching it back on it starts cycling the ports again.

Going to try and get it exchanged tomorrow.

Thanks for your help though Paul.
