Baird 240 line Operation

The above is a less than perfect depiction of the flicker of the 240 line display but gives some impression. (It probably works better if you set your display rate to 75Hz.)

I've put a fuller representation of the flicker simulation here

If you can set your display rate to 75Hz then it is very similar to the actual 25Hz flicker.

With the common 60Hz LCD displays the flicker is very uneven. This is more disturbing than the original 25Hz flicker. 25Hz would be incredibly horrible on a large, modern and bright CRT display. On a small and relatively dim pre-war set it was just about OK. On an LCD display it would be fine

There is no large area flicker on an LCD because of the inherent zero order hold functionality of LCD cells.

[peter scott]

Agreed. You really need to change to 75Hz display rate to get an even flicker.

Hi.
The Decca 1000 shows the flicker really bad, the reason is I think that the display on the MW6-2 is very bright and although on the 60 inch screen dull the short persistence of the tubes screen phosphor shows up how bad it was.
