right... I think I dont understand you fully.
The DX I run manages pictures no problem. of many different sizes. As 16 shades of grey is all it can physically manage I generally end up applying a monochrome-dither of some kind to get the best results.
I havenīt ever managed to get it to do a restart based on showing the images so far.
Thatīs really all I can report.
Posts arenīt moderator approved. They are very rarely removed. And never to my knowledge based on simple complaints about under-performant devices.
The DX is a slow, now old, device. Use it for what it can do and it works great.
It will never be able to perform like the newer devices.
