whois shows an admin contact at wintergroup.net. wintergroup.net (on http) is the home to a marketing agency, their client links below include "Epson" and "3LCD"; clicking 3LCD brings up a still image showing this page. Searching for 3LCD finds this Epson page: < http://global.epson.com/innovation/projection_technology/3LCD_technology/>. <http://3lcd.com/> has a very familiar 'feel' as well... and has an admin contact at Seiko Epson Corporation

I won't get into display theory on this list (feel free to contact me if you want to discuss such)

The only thing I can think relevant regarding projector/monitors in a NOC situation would be general eye strain issues, which should be taken in to account in the same way as keyboard/chair positioning etc by whoever is responsible for health and safety. Anything beyond eye strain is probably just getting in to colour reproduction discussions which are largely irrelivant in a NOC. I for example have all my monitors set to a lower colour temperature and dimmed as much as feasable, colour reproduction is terrible but great for avoiding eye strain. I switch back to reasonably normal settings for watching videos and films etc, but during normal NOC operation I doubt the colour accuracy needs to be able to distinguish more than than green/yellow/red (with maybe some shades between). - Mike

You might recognize my name.it's the one on the four page document highlighted above and available at www.colorlightoutput.com I'm a product manager for 3LCD. I'm a little surprised by the comments suggesting we were trying to hide the identity of 3LCD behind the site. Clearly the site doesn't scream3LCD.it wasn't supposed to. The "Hero" of the site is Color Light Output. The purpose is to provide information about this new measurement methodology.not present the technical details of 3LCD. I thought the 'feedback' page fairly well spells out who was behind it. That said, I will take these comments and make adjustment so that's it's clearer who is supporting the site. Regarding the projectors selected for testing in table 2 of the document. It is true that all of these projectors are single chip models with color wheels. Why is that? As Scott points out above, an RGB 3-path projector will always have equal parts of WLO and CLO. I know already how an NEC LCD projectors is going to perform. Only single chip projectors were tested in order to better understand how each Color Wheel design impacted CLO. I do admit that the list is heavily leaning towards the biz/ed side of the projection market.that's due to the makeup of sales volumes; only about 10% of projectors are sold into home theater. I hope, regardless of the company on my business card, that you'll agree with me that providing the customer this additional data is a good thing. My aim here is to get all manufacturers to list CLO as a supported metric."
