The HP screen is for brightness fanatics.
One of the main benefits is that I can run the RS55 @ -13 or -11 iris and the contrast looks very good on the my dark sci-fi flicks.
kraine published these #'s in his review of the X70 (RS55) and the VW95. Obviously there is sample variance between models, so another VW95 and RS55 could have different results. Keep in mind the lamps will dim over time, so it's at good as it gets out of the box.
X70 (RS55) Contrast / Brightness:
High lamp mode calibrated iris opened: 1051 lumens
Low lamp mode calibrated iris open: 666 lumens
Value of the calibrated lamp black high iris open: 0.01 lux
Value of the calibrated lamp black bass open iris: Unable to measure in the field of the screen, our light meter has reached its limits, we get closer to the goal to obtain a measure of contrast.
We contrast: off low lamp calibrated: 40100:1
We contrast: off lamp calibrated high: 21000:1
Brightness behind 3D glasses: 299 lumens
VW95 Contrast / Brightness:
Calibrated high lamp mode: 770 lumens
Calibrated low lamp mode: 495 lumens
Value of the calibrated lamp black high: 0.02 lux
We contrast: off lamp calibrated high: 14150:1
Value of the calibrated lamp black low: 0.01 lux
We contrast: off low lamp calibrated: 18250:1
Brightness behind 3D glasses: 283 lumens
Dynamic iris turned on in auto mode we measured a 28300:1 contrast is: off
