VESA Local Bus video cards on LCD monitor - video signal quality tests

Note that these signal and noise problems are much less or not visiabe on CRT monitors,
also note thas some of these visual problems visiable only on frame grabber device.
Even the worst one is fully acceptable on a CRT monitor!
