JVC RS440U vs RS400U?

What real world improvements are there in the 440 vs the 400?
Also is there a list of the various JVC models showing the benefits/upgrades in each (looking to cross check vs. current used prices to find the "sweet spot"

If I recall correctly.

440 has much lower input lag (only matters for gaming), slightly sharper e-Shift, no banding when using CMD (frame interpolation mode).

Get either a 420 or 440. They are nearly identical. Both are much more user friendly than the dreaded gamma d on the 400. My son had the 400 then went to the 420 . They all throw a similar picture.

Also dynamic iris works with HDR and has much better implementation of HDR.

I forgot about the iris.

But if you install Javs/Manni curves on 400, 420, and 440 wont they all look the same for HDR?

Just talking differences in the projectors themselves.
