DELL E193FP input lag and response time

Measured using the pi lagtester PRO.

19 inch 4:3 screen. 1280x1024 resolution, doesn't support interlaced modes. Only VGA in. 

At 60hz:

Input lag (first response at top of the screen) is always 6ms independent of resolution.

Scanout (top to bottom) takes 16ms.

Response time is awful, about 22ms. 

Thus, to see a pixel respond at the lower edge of the screen takes about 6 + 16 + 22ms = 44ms. Yuck. 

Interestingly this display supports 75hz, which improves things. The response at the bottom of the screen improves from 44ms to 38ms.

Since this is an old obscure LCD I've not bothered to add it to the database or do a full review.
