(DIrty Screen Effect, all over!)
Now I'm asking if it is advisable to move into PLASMA? What are the common issues here?
I'm very particular with screen uniformity, and I know that PLASMA will produce deeper blacks than LED could ever do. Question is, are there common issues with PLASMAs that I should look out for?
I'm eyeing the D7000 series mainly because of its good reviews on CNET, Television Info, and the likes. It's cheaper too over here in the Philippines than my Sony EX720 so I figured I'll place it on our Living Room and will mainly use it for gaming, movies. (Seldom 3D use)
How's the set? How's PLASMA in general this year? Thank you in advance guys!
I hope this helps and doesn't necessarily discourage you, but here are my experiences...(disclaimer - I'm in Australia so a couple of the following points may not be applicable to North American models)
I recently purchased the Panasonic GT30 (46" plasma), coming from a 68cm Loewe CRT.
There was an atrocious green blob on the first one and a much better but still noticeable green shadows on the second. As such they were returned. However, I learnt something more important than the severity of the Panny green blob issue (at least for my eyes anyway). Here are the long list of things that ended up bothering me - some specific to Panasonic and some inherent to plasma technology. Some I already knew of, and others I had not noticed (or had chosen to ignore) while researching my 'dream' TV. I hope this helps others.
Firstly, yes the picture quality of the plasmas is very impressive but if you have sensitive eyes...
*Phosphor decay / lag issues mean that if you are sensitive to this you will often see red and green 'shadows' either side of the leading edge of high contrast images. It drove me crazy! My partner couldn't see it and I started to think I was imagining things until I discovered a few long running threads on AVS on the plasma 'rainbow' effect (the 'it's official thread' is the best of these). I am unfortunately in a small club of people who see this. Sin city is a good test disc - high contrast and black and white. You should not be seeing colour in this movie.
*The Panny plasma's suffer a '50Hz bug' which (as best as I can determine) exacerbates the above effect (mentioned in very few reviews - but check the gt30 review on AVforums for more info. Not relevant for you if you're in North America)
*Plasma TVs do flicker and if you are sensitive to this this may be annoying. Particularly noticeable in your peripheral vision.
*Panning is quite jerky - more so than on LCDs I've seen. Not sure of the correct term for this. It is fixed by engaging the soap opera effect which I can't stand
*All plasmas buzz (don't let people tell you otherwise). It is faint but the tone/intensity of the buzz definitely changes as an image increases in brightness. Not a deal breaker for normal listening but annoying late at night with the sound low. Some sets buzz more than others so there's a bit of pot luck involved. It doesn't bother most people for the most part but still...
*The GT30 has a disturbing green push across all image modes, particularly the THX mode (there are more reports for this with the Australian/European models - not so bad in the North American models so I'm led to believe. My observations were confirmed by a local ISF cert calibrator). Can't believe how bad the colours are in this mode. This is mentioned in reviews but hard to accurately fix yourself. As an aside this is something that annoys me about TV reviews - yes a TV may well be capable of extremely accurate colour reproduction (as is the GT30) but unless you are prepared to fork out the $400 or so for an ISF calibration you are going to struggle to get it right yourself. I would have needed to have the GT30 calibrated despite not originally planning to do so. Turns out I'm fussier than I thought. Either that or my old Loewe TV was more accurate than I thought. Why don't all reviews assess the out of the box modes more thoroughly? Perhaps people's ultimate purchase might be different otherwise
*I forget the correct term for this (posterisation? dithering?) but if you are sensitive to this shades of the same colour will not smoothly be displayed. ie a blue sky won't have the blues smoothly blending but will have distinct bands.
Anyway, the green blob and phophsor decay issue / 50 Hz bug were the deal breakers. The rest I would gladly live with given the otherwise excellent quality of the image in a dim room. However I'm going to have to go LCD due to the phosphor lag in plasmas (unless they speed up the decay, or at least get the colours to decay at the same rate in future models - keeping fingers crossed for 2012 models). I'll have to spend twice as much too and suffer the LCD probs you have described (uniformity, blooming etc etc and the rest). Pick your poison... A note to those considering a plasma. You need to assess a plasma in a darkened home theatre room. Torch mode amongst all the other TVs under bright lights reduces the overall contrast and makes detecting flicker, phosphor lag etc extremely difficult in store. If you don't see these and other issues then you are lucky and I'm jealous.
Hope this helps you Calicool. Cheers
