Panasonic TC-P50G20 June 2010 Home Theater magazine review
** Flicker and a decreased brightness with 48HZ mode (No 96HZ flicker free mode)**
According to the Home Theater magazine review
the G20 series uses a 48HZ refresh rate that causes a flicker and reduced brightness on the screen (Issue occurs when the 48HZ mode is turned on in the G20 while watching a 1080p/24 Blu-ray disc). Most likely one of the reasons why the Panasonic reduces its brightness when in the 48HZ mode is to reduce the flicker to a minimum. The brighter the screen the more noticeable the flicker is. In the movie theater and on most Front Projectors 48HZ appears flicker free since the brightness is a lot less compared to plasma and LCD flat screens. Panasonic does make true 96HZ flicker free displays that bypass the 3:2 pulldown process when watching 1080p/24 Blu-ray discs but it costs more money for those models.
One has to use the 60HZ mode with 3:2 pulldown to get rid of the flicker and keep the brightness normal for the G20 series. The black levels on the Panasonic TC-P50G20 display is also disappointing when compared to the discontinued 2008 model Pioneer plasmas.
Here are a select few quotes from the Home Theater magazine review
"For 1080p/24 sources, a 24p Direct in setting gives you the choice of either 48 hertz (frames per second) playback (each 24-fps frame flashes twice, with no 3:2 pulldown) or 60 Hz (the set converts the 24-fps source to 60 fps with 3:2 pulldown). With earlier Panasonic sets, the 24-fps setting decreased brightness and added visible flicker on scenes with large expanses of white or a uniform color (a bright blue or clouded sky, for example). The flicker was relatively subtle here, but I noticed the reduced brightness. Because of this, I did much of my viewing in the 60-Hz mode. The increased judder that the 3:2 pulldown caused didn’t bother me."
"Rather, my disappointment came from excessive expectations. Rumors arose in the past year (now unofficially confirmed) that many of Pioneer’s KURO engineers had moved over to Panasonic when Pioneer got out of the video business. Based on that, we—and other video enthusiasts—were hopeful that Panasonic’s Infinite Black technology meant that KURO was back, with only the name changed. But for this year at least, that is definitely not the case—at least not in the G20 line."
"It was probably wishful thinking on my part to expect a $1,500 set to offer the sort of performance that once commanded a $5,000 price. Set makers this year, including Panasonic, are putting most of their engineering resources into 3D. But for the future, we can hope that Panasonic will give us the true black-level break-through we know it’s capable of."
