) produces a wider color gamut than alternative backlights. I have not seen mention of a WCG-CCFL backlight in Sony's LCD TV specs since the V2500 was introduced. These links: http://www.reviews-lcd-tv.com/Sony-B...cd-review.aspxhttp://www.reviews-lcd-tv.com/Sony-B...cd-review.aspx
indicate that only the Z4100 series will have a WCG-CCFL backlight. Is the color gamut on my V2500 better than newer models like the W3000 and W4100, because it has a WCG-CCFL backlight? What are the real color gamut differences between Sony models? Is this information available anywhere? Maybe all new Sony LCD TVs have WCG-CCFL backlight, but they just don't state it anymore?
The XBR4, Z4100, and WL135 series have a WCG backlight. The V4100 and W4100 don't. Models that have a WCG backlight have a Color Space option in the menus. You can select either Wide or Standard. Based on my experience with the WL135, that option actually makes a visible difference, but not always for the better. TV usually looks more natural with the standard color space (at least to me). However, Blu-Ray and games definitely benefit from the wide color space (if you have a PS3, set RGB Full Range to Full in the display settings).
There's a lot of talk about 10-bit vs. 8-bit, but the backlight is probably the most significant difference between the Z4100 and the W4100.
I don't have hard info on the gamuts, but I suspect it's 72% NTSC with a standard backlight and 92% or higher with a WCG backlight.
