kkjj made his source code available for inspection here.

Why scaling is necessary

Some software is only capable of running at higher resolutions than the eee's 7” LCD supports. This is especially true of games though it also includes software that contains large non resizeable windows.

How scaling works

Scaling forces the eee to render the screen at a higher resolution, say 800×600, and then squishes the image down to 800×480 to fit on the eee's internal display.

Problems and limitations

This results in some distortion of the image and some degradation of image quality. The degradation in image quality is most noticeable in text though users have reported being satisfied with the appearance of text at 800×600. In exchange you can now run software that can only be run at higher resolutions. Turning ClearType off will improve appearance.

Current solution only supports 800×600 and 1024×768. It is possible further support will be added later.

How to add this feature

Before you Begin

You will need to install Windows XP on your eee to attempt this modification. There are many options for doing this. Please see the main wiki page for instructions on how to install alternate OS on the eee.

Step 1: download files

  1. you will need either the video driver for the R2H or the modified Intel or Asus drivers from LazerTag
  2. you will need the kkjj's EEEPC_Utility.

Step 2: Read any included "Readme" files

  • Read any files containing readable text that might be supplied with drivers or software

Step 3: Install driver

  1. uninstall old display driver.
  2. Install modified driver using either kkjj's or LazerTag's
  3. In advanced display properties uncheck “hide unsupported resolutions”

Step 4: Run kkjj's program

  1. Set output to Notebook only.
  2. run the EEEPC_Utility program and follow directions to pick resolution.

Step 5: Make improvements to this article

  • add screen shots of steps
  • add better directions
  • fix typos
  • Turn ClearType off.
  • If in 1024×768 font, a DPI of 144 looks much nicer.
