How many (lowres, non-interlaced) pixels can the Amiga actually display?
There is an interesting thread about it here
, but it could be interesting to hear if people here have any further experiences, particularly for OCS.
One thing that is immediately clear when delving into this is that it depends on the display device. And in these days of scandoublers and whatnot, there is a lot of variation to be seen here. I have tested an external (Mikronik) scandoubler on my BenQ monitor, a composite signal on my BenQ monitor, an RGB-scart cable on my (modern) TV, and WinUAE. All give different results. :)
It seems pretty consistent that the earliest display window start that can be displayed is $1A. WinUAE can display up to a display window stop of $139 (full PAL long frame height), but the highest I could get other displays to show is $138 (with one extra line of background color displayed below it). So we have 286 or 287 lines.
I saw several displays which could go to $1D4 on the right (normal non-overscanned + 19 pixels, i.e. data fetch stop $D8 and shift value 3, last word wholly visible) but none further than that.
On the left, WinUAE can start as early as 376 pixels before this (i.e. data fetch start $20 and shift value 11, first word wholly visible), but none of the other displays would show more than 368. This seems to be the place where there is most variation.
From the right and bottom limits it seems that the maximum symmetric overscan is 358x280.
Anyone here with a CRT monitor or CRT TV who wants to test this further? :)
