You seem very determined to ignore what I've said I want and insist I have to buy something I can't possibly afford.

Look at the GIF images on my flute music pages. That will do. A lot of what I'm actually playing from is higher resolution than that, but I can key it in as ABC and use a cruder and clearer image.

Speed of access is much more of a problem than resolution. Since I've never used a digital picture frame I've no idea what their user interfaces can be like.

Two hundred sheets of A4 would be a bit much for most music stands

Wobbly but it works, and my stand is pretty basic. Hasn't fallen over for months.

I carry a lot of instruments and accessory clutter around anyway, I can't take on a solution that involves even more weight and complexity.
