LCD Lag tester

[Jensen]

I made a simple counter in flash.... It increases the count by one every 1/100 of a second.
It will not sychronize with the refresh, of course, so it needs to be tested several times for accuracy.

Set two monitors in Clone Mode, run the flash counter, then take a picture of both screens at once. (set your camera to 1/60th of a second, and the monitors' refresh to 60hz). Take a few pictures.

When using my 2405 LCD and my CRT in clone mode, the 2405 lags a bit more than 3/100 of a second.

I'd like to see someone test this with a different LCD and a CRT, and also test it with two different LCDs (one of them being a 2405).

This lag is my biggest complaint about the 2405.... the ghosting isn't bad, and the color is great. The lag is even worse with composite input (my Gamecube).

DOH! I forgot the link! http://webpages.charter.net/shadowfax1/counter.html

Hmm.... the counter runs slower in a browser than in the Flash application....

Hi Jenson,

I did notice whilst I was doing my test last night that (in a browser) if I left it running for a bit, the counter increment would start to slow down.

I posted some comments pertaining to Flash and resolution with teh 2405 over here:

this one is much better - bigger numbers, better time resolution
