Hi All, I hope these justify a new thread, I think they do as I couldn't find the answers elsewhere!...Joe Fernand are you out there? I have owned an NEC 42MP2 for the last 18 months, (& an NEC 4210W before that ) and I've been very happy with both of them. Two things now make me think it might be the right time for a change: The superior 3000:1 contrast ratio & resultant "Blacker" blacks that have been generated by all the Panasonic models since their 3rd generaton, and now, the introduction of a Higher Resolution 42" model in their 5th generation screens. I'll direct these questions to Joe as I know he is well placed to have been able to perform "side by side" comparisons, but I would welcome input from everyone! OPTIMUM PLASMA RESOLUTIONS What do you believe will be the optimum resolution for HD DVD? I'm thinking about "native resolutions" and the requirement or otherwise, of the screen to "up convert" an incoming signal. I assume the current VGA 852 x 480 resolution of my NEC 42MP2 and the TH-42PWD5BX would be insufficent to get the best from a HD DVD signal? So, do you think that the XGA 1024 x 768 resolution of the TH-42PHD5BX or the XGA 1366 x 768 resolution of the 50" TH-50PHD5BX will be the closest fit? Are both of these "True" XGA resolutions? What will be the effect on picture quality for the less accurate fit? I'm also looking for an answer to this question when it's applied to the use of "PROGRESSIVE" & "INTERLACED" signals from our current DVD players? Is 852 x 480 still the optimum resolution for both of these? I do not currently own a DVD player that outputs a Progressive signal, but I may invest in one in the future if I give up waiting for HD DVD, so what is the best resolution for these? Are the Higher resolution XGA models less suitable for our current DVD players? I believe I'm right in saying that that they are effectively "over specified" and would need to "up convert" the resolution of a normal Component signal? What do they do to a Progressive signal? Does their internal scaling take over? ps: I think I read somewhere that the Progressive output from Sony's DVP-S9000ES was not suitable for my NEC 42MP2? Is this true? Why? Would I have to use the Interlaced Component signal from this player? Does this apply to all Progressive players when linked to the NEC 42MP2?...Anyone know? SINGLE SCAN v DUEL SCAN ( Thanks go to aRCaM for highlighting this issue! I certainly wasn't aware of it prior to his post. Though I'd like us all to try to keep the emotion out of the discussion this time! ) The old thread on this subject closed prior to Joe coming back with his findings on any possible "visible" impact of this change in the way that the image is produced on the Plasma screen. What's the story Joe?....does it make a visible difference?...are there consequences such as "flicker" as some people have reported? Does this make the 4th generation standard resolution TH-42PWD4BX ( duel scan ) a better purchase than the 5th generation standard resolution TH-42PWD5BX ( single scan )? If yes, is this to the extent that it makes the new higher resolution TH-42PHD5BX ( which I believe is still duel scan ) the better bet from the current 5th generation 42" models? Is this change a result of attempted cost savings at Panasonic or a supposed improvement? Could it even be an attempt to resolve the noise problems that appear to plague so many owners? BRIGHTNESS One specific question. The old 50" TH-50PHD30BX model had a 500 cd/m brightness right? So, Why has the new 50" TH-50PHD5BX model now got a quoted 300 cd/m brightness? This seems like a substantial reduction in the new model, Is this "visible" in a side by side comparison? I believe both models are duel scan, and that the resolution of the new model is the same as the old one, so whats the reason for this reduction in brightness? Does this make the newer model inferior? Joe, on your Media Factory site, the older model currently retails at £6,330.50 while the newer model is for sale @ £6,243.28, ie: LESS! Whats the story here? Also, generally speaking, do the differences in brightness across the 42" range, ie: 4th v 5th generation, & standard 5th gen v HD 5th gen, actualy amount to a "hill of beans" when watching in a darkened room as is always the case when I use my screen? THE NOISE / BUZZ / HUM ISSUE What's your stance on this Joe? Have you experienced it? If yes, is it present on the 5th generation models too? Is it across the range on all sizes including the 50" models? Does the Single Scanning of the new TH-42PWD5BX model have any effect on the noise? So, lots of questions! Any answers? ( ps: Joe, fyi, it would appear that on the Media Factory web site, you've "cut & pasted" some of the older 50" models specs into the newer 50" models details as there is still a reference to the 30BX at the end of the 5BX's information, I think you might want to remove this? ) Best Regards, KBDVD.
