LED LCD = more input lag: old wives' tale?

I'm looking at the:

ASUS VH238H

and the ASUS VH236H
http://www.newegg.com/Product/Product.aspx?Item=N82E16824236059&Tpk=ASUS%20VH236H

From some posts I've seen, the VH238H is basically just the LED version of the VH236H. IF that's true, will the input lag be higher on the LED screen? I have heard completely conflicting thoughts on this. But I'm trying to figure out what's real, and what's B.S. I'll be using the monitor as my all around PC monitor and for PC gaming. Are there any other pros/cons for LED versus traditional LCD's other than power savings?

Could be different monitors since the viewing angles on both monitors are different.

The backlight has no effect on input lag whether it is LED or CCFL backlight.

LCD monitors with LED backlight pros:
- Reduced power consumption
- Thinner because of edge backlighting instead of full array rear backlighting
- Lighter because of edge backlighting

LCD monitors with LED backlight cons:
- Edge backlighting generally means the backlight itself can be less consistent than a full array rear CCFL backlight
- Backlight bleeding along the edges are more prone to occur
- Some people have reported that colors are slightly bluish. This is because the LED backlight (a.k.a. W-LED) is not actually pure white light, but blue LEDs with a yellow phosphorous coating to imitate white

This seems to coincide with a lot of what I've heard. Thanks. I've heard that the LED lighting itself can cause lag, but that didn't make any sense to me. So this clears that up.

Applecinema is a good example of LED LCD but I learnt less negative response.
May I know Applecinema is an edge blacklight or dynamic blacklight?
Also, LEDs using by it is white or RGB?

I believe Apple Cinema Displays use edge backlighting. They use W-LED backlight.

The only RGB-LED backlit monitors I know of are relegated to the high end professional LCD monitors. You know... the ones that costs in excess of $2,500+.
