The Sinclair QL Forum

It would if it HDMI and SUPER HD where you Run QDT in 4K Micro SD Card where QDT's Win File on the Card a power button 128 MB of Ram so QDT runs Better on 128 MB of Ram lot's of space on the motherboard so it is easy to upgaade it to 256 MB of RAM OK Thanks simon 629

In HD, 2 bytes per pixel, you're looking at 162MB for just the screen. Open one window over another window covering half the screen and you're at 240MB. So in this 256MB system, you can only open two windows.

Simon, it is very difficult to understand some of your writing without interpunction.
As Dave said - and try scrolling the screen :/

BTW just as a reference - the QL can address up to half a gigabyte of memory TOTAL (this includes all RAM, ROM, IO...) if it wants to stay compatible with most of the available software. Actually, it would be a good idea to provide the maximum amount to begin with since it's really not that much in modern terms.

How have you calculated that?

For me 3840 pixels × 2160 lines = 8.3 megapixels = 16 MB

16.2MB. Lost a decimal point somewhere.

Thanks for spotting that.
