This is a battery operated signal generator / tester for VGA monitors. It intended to be taken on the road to test old VGA monitors, whether it’s for touchscreen countertop games, or old PCs.
It supports the 15.7kHz video mode (320×240 non-vga standard) to help you find those elusive LCD panels that can be used for console and arcade gaming natively, as well as the more common 31kHz (640x480), 38kHz (800x600) vga modes. 

Outputs

Video and sync signals:
- RGB and SYNC at 1V-pp into 75ohm.
Sync Types:
- Negative HSYNC
- Negative VSYNC

Video Generation

15kHz – 320x240 CGA/EGA resolution
31kHz – 640x480 VGA resolution
38kHz – 800x600 SVGA resolution

VGA Video Tester Features and Additional Information

Generates the following tests in each mode:
  • Text – for raster direction / yoke polarity
  • Color Grids Primary Colors – for color check and adjustment
  • Color Grids Primary and Secondary Colors – for color check and adjustment
  • Checkerboard – for geometry and convergence checks, white / black level / saturation
  • Grid - for geometry checks
  • Convergence Grid -  for convergence checks
  • Pong - streaking test
  • Hollow / Filled Box – for bloom artifact check
  • Moving Crosshairs - geometry distortion check
  • Vertical Primary Color Bars – for color check and adjustment
  • Vertical Secondary Color Bars – for color check and adjustment
  • Vertical Tertiary Color Bars – for color check and adjustment
  • Scrolling Horizontal Color Bars – bloom and color uniformity
  • Solid Full Screen White – for burn in and degaussing
  • Solid Full Screen Red – for burn in and degaussing
  • Solid Full Screen Green – for burn in and degaussing
  • Solid Full Screen Blue – for burn in and degaussing
  • Alternating Color Grid - color transitions / color saturation test
  • Alternating Full Screen Color – burn in, degaussing, color transitions
  • Random Color Grid - stability testing, demo mode, etc...
Battery life indicator shows battery status through MODE LED.
  • LED always on – full battery
  • Duration of on/off cycle indicates battery depletion level
  • 50% off/on blink – nearly dead

To operate the dongle, plug it directly into the monitor side VGA port and turn in on. Press the MODE button to cycle through the available video modes, and TEST to cycle through the tests.

The tester itself will only plug into the female DB-15 jack on the back of your monitor. In order to use a typical VGA cable (male ends), you will need the optional gender changer which you can order with the tester.
