== Quality ==
On a modern flat screen LCD television the image quality from the Videomaster is worse than the SCART cables you can buy and worse than a native green screen or colour monitor. (This is using a composite to SCART cable).
Mode 0 is fine, mode 1 is useable, but mode 2 is hard to read. This is down to ghosting in the image. With the yellow on blue the ghosting is black. I (arnoldemu) have seen similar when using the SCART output from a KC Compact on a television so it may be that the signals are not acceptable to the modern TV.
The colour reproduction is good although bright white is a little dull for me. My television also has trouble with bright green in that there is visible moving dot crawl around the edges. There is also some noticeable banding between main display and border when the border colour is different from the main area.
Like the SCART, register 3 scrolling can be used (use values 5/6 for hsync length - any lower and the picture loses sync), and like the SCART if you try to use lower hsync lengths and if the border is not black then the main display will become darker.
It has also happened that when the television looses sync and when you then re-sync the picture is black and white with noticeable dot crawl all over it. I don't see this with a SCART cable.
I believe the problems I am seeing are down to the higher R,G,B voltage output from the Videomaster and using a composite to SCART.
Unfortunately I am unable to compare this with Amstrad's modulator. I will try the Videomaster with a composite cable (if I can find one) and on an older Sony Trinitron CRT television.
