Received & installed my 4810.
Thanks to Mike and AVS for the great service, pricing and attention to you're customers.
Previous projector: RS40. Screen: Da-Lite JKP .9 gain( no interest in 3D)
When my 4810 had already been shipped I considered returning it factory sealed to AVS and exchanging it for a 46.
Why? Due to the impression given by a few on this and other forums that 4k technology was basically some very expensive form of terrible looking digital sharpening.
With the 4k set on Film and controls on factory 50 50 50 my image quality is fabulous. Incredibly natural detail.Nothing even close to a cheap video look. The high resolution setting is just too detailed and noisy for my taste. Film setting is perfect. And at least with my dark(.9) screen the factory settings are just right. Impressive amount of detail w/o noise. My calibrated RS40 can't come even close.
If I switch off the Eshift 2 the image is a bit softer than my RS40 but this is because the factory sharpness & detail settings when off are too low(0 0 0). But even if I raise the sharpness to the level of my RS40 it can't match the 4810 w/ Eshift on (50 50 50).
Some have expressed that 4k Eshift 2 can only be enjoyed if you own at least a big 120" screen and you watch at a close .5 to 1.3w distance.
Well the fantastic image quality that I described is on a Da-Lite JKP screen 92" diagonal and 80" w. Seating distance 1.5w
I'am positive that even smaller screens can benefit from Eshift 2 technology.
As Mike G. mentioned pixel structure can only be clearly seen at 12" from the screen(eshift off) but makes a huge difference at normal seating distances(eshift on).
I can't remember having seen any display that looked so good basically out of the box. No calibration until at least 50 hrs. on the lamp.
Colors and specially flesh tones are spot on. The new RS46 according to many owners also enjoys from having some really good factory set colors.
An RS40,45 or the new 46 by themselves look really good. And probably fantastic with the very affordable Darblet.
But if you can afford the 4810 go for it. It's fantastic and for the AVS pre-order price a great bargain considering it's performance and features.
