Prevent Display scalling

Apple Macbook aluminum
March 29, 2010 at 16:59:55
Specs: Windows 98SE, 604 120MHz/40MB
I got this laptop and installed the correct display drivers, just I have an application that runs 640x480, but the laptop scales it to 800x600, and distorts the image, another laptop I have centers the 640x480 image on a 800x600 blank screen, is it possible to make this laptop do the same thing?

You're running Win 98 on a Macbook ?
You're running only Win 98, or are you running Win 98 in a virtual box on the Mac operating system?

Both 640X480 and 800X600 are 4:3 display resolution ratios.
If the physical display is 4:3, there should be be no distortion of the image at 800X600.

On the other hand, if the physical display is wide screen, e.g. a 16:9 ratio, if a 4:3 resolution is stretched to fit the screen, yes, it would be stretched horizontally.

I don't have any widescreen display, but I would presume if the physical display is widescreen there should be some way in the settings for the video that you could have it NOT stretch a 4:3 ratio resolution horizontally - you would have black bars left and right where nothing is displayed.

If you're running Win 98 in a virtual box on the Mac operating system, you may a find a setting that applies in universal access settings.

Go into the system preferences (under the apple menu), and click on 'universal access.

It's a compaq armada 3500, the forum won't let me change it from my old laptop. The problem is that have scaling is done to make 640x480 to 800x600 so only some pixels are stretched, making the image distorted,

"compaq armada 3500"

A search on the web finds it's physical display size is a 4:3 ratio - it's native or optimal resolution is 1024X768.

All of 640X480 and 800X600 and 1024X768 are 4:3 display resolution ratios.
The physical display is a 4:3 ratio - there should be be no stretching of the image at 800X600.

If the image is stretched, you probably have the resolution set to a widescreen resolution ratio.

RIGHT click on a blank part of the screen - Properties- Settings - set the resolution to 640X480, or if you can't do that, to 800X600.

"...the forum won't let me change it from my old laptop."

What forum?

The display's native resolution is 800x600. I am attempting to run an old DOS application with a resolution of 640x480 (Standard VGA) the image is scaled (maybe a better term to use than stretched) to 800x600. I was hoping someone has the same Chips and Tech 69000 graphics card or the same laptop and knows of a way to turn off display scaling.

As Tubesandwires stated, 640x480 and 800x600 are both 4:3 aspect ratio, so that difference should not cause your problem. Check your laptop manual for a display setting that might cause the stretching.

I'm assuming you're using the built in LCD display on this computer.
If you are NOT and you are using an external monitor, there are other possibilities for your stretched display.

"The display's native resolution is 800x600."

You may have the resolution set to 800X600, but this model's native resolution is 1024X768 !!!

All LCD displays have a native or optimal resolution that looks the best - usually that resolution is also the maximum resolution of the display. You can choose other resolutions in Windows (or whatever operating system), but they will not look as good as the native or optimal resolution.
The most noticeable thing is text is not as clear in other than the native or optimal resolution - you can't do anything about that in Win ME and below, but Microsoft has Clear Type for 2000 and above.

More info native resolution:

In the case of this display, any resolution that has a 4:3 ratio will be proportioned correctly, if other things are right. .

If the display is truly stretched at 800X600, it's also stretched at 640X480 and 1024X768.

This system was probably made in 1999. It's extremely unlikely anything to do with the Chips and Tech video drivers are the case of your problem.

You probably have the wrong Monitor drivers loaded.

When brand name systems have their original brand name supplied software installation on them, the Monitor type is set to suit the model.
When you merely load Windows on the hard drive, the default Monitor type is probably not right, for a laptop.

I'm guessing that these are probably the right drivers:

RIGHT click on a blank area of the desktop screen - Properties - Settings
Advanced button - Monitor tab - Change - Next - Display a list....., Next - click on the circle beside Show all hardware
In the list on the left -
Standard Monitor Types - Laptop Display Panel (1024X768), Next - Next - Finish

If anyone else has my problem, the answer can be found in the users manual, display scaling is disabled with Fn+T

Okay, good to know, but the laptop would not be set to that by default - you must have pressed the keys by mistake.
