In this video, GRay Defender demonstrates the Checkmate S-Video upgrade, a simple yet effective improvement for the Checkmate monitor. After long wanting this addition, he finally installs it and walks viewers through the process in detail. The upgrade kit includes the main board with S-Video, composite, and component inputs, stereo audio jacks, an HDMI output, a short HDMI cable, screws, and even its own remote control.
Glenn shows how the new board replaces the existing rear module on the monitor. While installation looks straightforward, it requires careful alignment and securing of the HDMI jumper cable to link the board internally. Once fitted, the Checkmate monitor gains a full range of video inputs, allowing for better flexibility when connecting classic hardware.
Testing with a Commodore 64
With the S-Video board installed, Glenn connects his red Kickstarter Edition Commodore 64 using a 1541 Ultimate 2 Plus cartridge. He demonstrates both composite and S-Video outputs, switching between them to showcase the difference. After some minor issues with the remote, he navigates through the input options and shows the results side by side.
Comparing Picture Quality
The Checkmate S-Video upgrade quickly proves its value. Glenn points out how the composite signal looks softer and slightly fuzzy, while the S-Video output through HDMI appears sharper and more defined. Colors show stronger contrast, and on-screen text is much clearer. When switching between the two modes, viewers can easily see how much crisper the upgraded image looks, especially during gameplay tests.
Final Thoughts
Although the Checkmate S-Video upgrade carries a higher price than expected, Glenn Defender believes it’s well worth the cost for retro enthusiasts. It enhances image quality, expands input options, and makes classic systems like the Commodore 64 shine on modern displays. His demonstration proves that even small upgrades can make a big difference in the retro setup experience.
