At this rate we'll be to 1,000,000,000,000,000,000,000,000,000:1 Contrast Ratios by 2009!]]>Oct 24th 2007 2:52PMhttp://www.engadgethd.com/2007/10/24/lg-shows-off-g-platform-plasmas-with-30000-1-contrast-ratio/http://www.engadgethd.com/2007/10/24/lg-shows-off-g-platform-plasmas-with-30000-1-contrast-ratio/
Saying all that, I honestly don't believe the public even understands the contrast ratio problem, one of the benefits of OLED we are led to believe is its contrast ratio, but in my opinion you will have two same size sets in a retail store, one LCD and one OLED and the customer wont be able to see the contrast difference, so they will end up buying the less expensive LCD.]]>Oct 24th 2007 4:49PMhttp://www.engadgethd.com/2007/10/24/lg-shows-off-g-platform-plasmas-with-30000-1-contrast-ratio/http://www.engadgethd.com/2007/10/24/lg-shows-off-g-platform-plasmas-with-30000-1-contrast-ratio/
"untrained" eyes cant tell the difference in contrast ratio, and even if they did its hard to tell in a department store all they show are bright colorful scenes not dark dim scenes]]>Oct 24th 2007 4:54PMhttp://www.engadgethd.com/2007/10/24/lg-shows-off-g-platform-plasmas-with-30000-1-contrast-ratio/http://www.engadgethd.com/2007/10/24/lg-shows-off-g-platform-plasmas-with-30000-1-contrast-ratio/Oct 24th 2007 6:01PMhttp://www.engadgethd.com/2007/10/24/lg-shows-off-g-platform-plasmas-with-30000-1-contrast-ratio/http://www.engadgethd.com/2007/10/24/lg-shows-off-g-platform-plasmas-with-30000-1-contrast-ratio/Oct 24th 2007 7:58PMhttp://www.engadgethd.com/2007/10/24/lg-shows-off-g-platform-plasmas-with-30000-1-contrast-ratio/http://www.engadgethd.com/2007/10/24/lg-shows-off-g-platform-plasmas-with-30000-1-contrast-ratio/Oct 24th 2007 10:26PMhttp://www.engadgethd.com/2007/10/24/lg-shows-off-g-platform-plasmas-with-30000-1-contrast-ratio/http://www.engadgethd.com/2007/10/24/lg-shows-off-g-platform-plasmas-with-30000-1-contrast-ratio/Oct 25th 2007 1:04AMhttp://www.engadgethd.com/2007/10/24/lg-shows-off-g-platform-plasmas-with-30000-1-contrast-ratio/http://www.engadgethd.com/2007/10/24/lg-shows-off-g-platform-plasmas-with-30000-1-contrast-ratio/
Of course, you could have a rather high-measuring black level and a ridiculously high white peak value and get a large ratio as well. Flat-panels, like rear-project televisions and direct-view (boob-tube) televisions were designed for ambient lighting and not critical viewing of shadow-detail.

In either event, who owns equipment that can actually measure the lowest insinuated light level to prove or disprove marketing claims by the manufacturers? I'm betting that 99.99% of the shoppers don't have it, let alone understand contrast ratios.

Then again, maybe some of you are not looking for the shadow detail because the viewing environment already sets the 'black level'. Then we need to start talking perceived blacks and not real blacks. ]]>Oct 25th 2007 3:20AMhttp://www.engadgethd.com/2007/10/24/lg-shows-off-g-platform-plasmas-with-30000-1-contrast-ratio/http://www.engadgethd.com/2007/10/24/lg-shows-off-g-platform-plasmas-with-30000-1-contrast-ratio/
The sites and magazine reviews that do measure it often report lower CR figures. Lumen figures with projectors are usually off as well. The same kind of shenanigans go on when makers report response times, different makers using the same panels in the same mode often show different response times, it's just based on how they chose to measure it.

The same goes for watts on amplifiers, they might measure one channel at a time maxed out to get the watt rating and multiply that by the channels, "500W", when the system might puke at 120W output to the speakers when used in multi-channel mode. Not that that really matters that much, I measured my use and found that typical power needed was less than 1 watt per channel.

Getting back to contrast ratio, for most people, I think anything beyond 1k:1 in real contrast ratio is fine.]]>Oct 25th 2007 7:54PM
