tsammyc Posted December 11, 2007 Posted December 11, 2007 Was down in Adelphi auditional HDMI 1.3 receivers and wandered into the Pioneer outlet on the 1st floor to listen to the VSX-LX70 (amazing how many Pioneer devices are all called LX70) which was OK, but didn't blow my socks off. However in the same room was C722's LX608. Now that blew my socks off. I had just been blown away watching ICE AGE blu ray on my HD80 through the Samsung 1400, but I was blown further away by the LX608. The blacks are so black that the two wolly mamoths look very different on the Pioneer, almost shimmering with depth to their furry coats and I'm sure its not Pioneer's new Blu Ray player. So after coming home, I popped ICE AGE Blu Ray into my PS3 connected to my 60" SXRD. I adjusted for maximum contrast (Auto Iris 1, Picture control to Max) This setting has been measured by ultimateavmag at 13,102:1 peak contrast, but ANSI checkerboard contrast of just 200:1. In comparison, ultimateavmag measured the Kuro 60" at a lower 4,795:1 peak contrast, but an astonishing 3542:1 ANSI checkboard contrast. This is a full 18 times the SXRD. By my observation, the picture on the SXRD does not come anywhere close to the LX608 in ICE AGE. The black in the wooly mamoths' coats was no where as contrasty and was relatively flat. Perhaps the SXRD might do better in dark movies like Batman Begins or Underworld because peak contrast on the Kuro isn't very high. According to ultimatavmag, Plasma's reduce light output when the Picture control is increased, and therefore dim their image, to remain within the capabilities of their power supplies. However these are just synthetic tests and I doubt there would be any way the SXRD would compare with the LX608 in any real world material, dark or not given the demo that I saw today.
c7221624705751 Posted December 12, 2007 Posted December 12, 2007 the picture on the SXRD does not come anywhere close to the LX608 count down to the date when u buy the pio... ;) "all I want for Christmas, is youuu...." ;D this is a very gd example of how ANSI contrast is so much more important than On/Off.... (hmm hint hint JVC HD# has only a tiny ANSI CR)
wind30 Posted December 12, 2007 Posted December 12, 2007 just curious which projectors has the best ansi contrast currently? Usually the numbers in the specs are on/off.
tsammyc Posted December 12, 2007 Author Posted December 12, 2007 BTW, there was a clear difference as welll between the LX608 and the 508XG outside. The 508XG does not have anything like the contrast of the LX608. I would guess that the ANSI contrast isn't close between the two panels...
tsammyc Posted December 12, 2007 Author Posted December 12, 2007 count down to the date when u buy the pio... ;) If a 70" is available at a reasonable price... but I'm thinking more about oled...
Doggie Howser Posted December 12, 2007 Posted December 12, 2007 count down to the date when u buy the pio... ;) "all I want for Christmas, is youuu...." ;D this is a very gd example of how ANSI contrast is so much more important than On/Off.... (hmm hint hint JVC HD# has only a tiny ANSI CR) Not trying to belabour the point :) but I still feel that while ANSI contrast may be lower (this is due to the pattern used) on the JVC HDx, in darker scenes, there is more shadow detail in the darker areas of the HDx vs DLP.
imbest Posted December 12, 2007 Posted December 12, 2007 If a 70" is available at a reasonable price... but I'm thinking more about oled... beware, I had bad experience on OLED, but that's on mobile phone......burnt mark burnt mark burnt mark!!!!!

There are infinite combinations of "intra scene" images. say 30% white at a corner, then some 20% at the border etc. In order to "measure" this, i.e. to have a common reference, ANSI comes out with that checker box pattern. So every display device can have a reference pattern to measure against. The ANSI pattern is quite fair. 50% white and 50% black intervened. If a display performs well in this pattern, we can be reasonably sure it performs generally well in "intra-scene" CR. But then there are this predominantly dark scenes. that's where On/Off CR comes in. So both are important. For Underworld, to be honest, watching it on the 608 is a joy. It probably does not have the best shadow details, but the contrast from the shining of the moon, reflection of the fires, sparks in the sword, is simply breathtaking.
