I just finished testing a TV and discovered that it actually starts drawing the frame from the bottom of the screen, and finishes drawing about 15ms latter at the top. This seems super crazy - why in the world would you do that, since video signals are always sent in the reverse order (top to bottom)?
Has anybody else ever seen this?
I found this design so perplexing that I did some digging and found about 15 other TVs which seem to use the same motherboard. If they all work the same way then this very odd design choice might not be so rare after all. I'd be curious if anybody else has one of these budget models (see https://alantechreview.blogspot.com/202 ... g-and.html) and can check if they too draw in reverse (you don't need proper lag testing hardware to tell, just a high(ish) speed camera).

Measure display input lag the cheap way or the best way (IMHO, but I'm biased).

I found a 2nd one that does this; this time from a mainstream manufacturer. Any idea why they would choose to do this?!?

All I can say to that one is: "Hm. Weird."

Yeah. When it was just one no-name manufacturer I figured it was pure incompetence, but toshiba should know better, even if they aren't the pinnacle of display manufactures. Unless there's some reason to do it that way I can't guess...
