CHRISTIE NEW HIGH CONTRAST 4K HDR RGB LASER PROJECTOR REVIEW
Not only is this without a shadow of a doubt the best video projector in the world, this is quite literally the best video image performance that I have ever seen in my life to date. Period. End of story. Goodbye. The End.
It significantly outperforms not only all other projectors, but also all other video display devices that I can think of with respect to overall video performance, across all formats, from televisions (whether OLED, LED LCD, MicroLED or otherwise) to modular emissive video walls.
In my opinion, this is the new video reference gold standard against which all other video displays should now be compared. It is quite literally the ultimate video display and with it Christie has set a benchmark of near insurmountable Everest proportions.
ON/OFF contrast and ANSI contrast by no means tell you the whole picture as far as contrast performance of video content is concerned. Why? Because neither ON/OFF nor ANSI are in fact directly applicable with respect to actual video content.
ON/OFF contrast and ANSI contrast are the two extremes of the contrast range that relates to video content. The ON/OFF Contrast only gives you the black level on a completely black picture. Similarly, the ANSI Contrast only gives you the black level at the extreme upper limit of video content brightness. Hence, typically over 99% of video content falls within these.
Consequently, in order to gain a proper understanding and to be able to properly assess and evaluate what is the comparative contrast and associated black levels performances regarding different display devices we really need to be taking measurements with respect to the contrast performance in-between the ON/OFF and ANSI contrast; namely the full range of ADL (Average Display Level) contrast.
Where ADL is defined as being the average on-screen brightness after gamma correction; and the ON/OFF contrast corresponds to an ADL of 0%, and the ANSI contrast corresponds to an ADL of 50%.
The following contrast measurements were taken at actual usage light output levels:
NATIVE ON/OFF CONTRAST (0% ADL) = 21,150,500:1
1% ADL = 83,649:1
2% ADL = 44,545:1
3% ADL = 34,730:1
4% ADL = 19,461:1
5% ADL = 15,452:1
10% ADL = 8,228:1
20% ADL = 3,771:1
ANSI CONTRAST (50% ADL) = 1,035:1
