Also, on a more constructive note, it occurred to me that one needn't restrict themselves to top->bottom scanning on some of the new systems. GLV for instance could be (it seems to me) arranged to scan 1080 from left->right (or right->left, whatever) and be an even smaller array.

Or even more interesting, if the scan was done this way and the array was a least common denominator of 480/720/1080 no external scaling would be needed - the projector could just gang a series of elements together.

For instance a GLV array of 4320 elements scanned from left->right would be able to directly display:

1080 - Gang 4 elements together.
720 - Gang 6 elements together.
480 - Gang 9 elements together.

Of course the same idea will work on a top->bottom scanned system, just with the need for a different sized array.

PS - Feel free to repeat this without citing the source, even though I believe it is an original idea.
