1) I prioritized LCD over Plasma simply because the plasmas were real hot and the LCDs were cooler.
2) LCD screens, when the backlight go kaput in about 60K hours, all you'd have to do would be to change the backlight CCFL tubes, a much cheaper process than changing the entire screen as you'd have to do in plasmas
3) Plasmas were more susceptible to burn-ins of continuously shown logos etc.
As if that were not enough, now I realise that HD broadcasts cannot be shown in their full 1920x1080 glory using today's plasma technology. So here's consideration 4:
4) Plasmas of today, have limited resolutions relative to similar sized LCDs, and cannot show full sized 1080i HD broadcasts without downscaling the image to fit the limited pixel arrays which plasmas typically have.
In a fit of interest, I started to buy some UK magazines like WhatHIFI and Sound & Vision, and I was shocked to see Plasma displays as a viable alternative to LCD TV screens in the HD arena. And it's incredible that some of the weird panel pixel counts like 1024x1024 or 1024x1080 screens can actually get a HD-Ready logo.
I can't stand this. Not only is there misinformation, there is actually some such `poorly designed' websites like this: http://www.hitachiconsumer.com/sg/products/proddetails.aspx?pid=1731&cid=107&tid=71 It does not list the pixel specification, only here does it list: http://www.hitachiconsumer.com/sg/products/download.aspx?file=42PD8900TA.pdf Whether this is on purpose or as an oversight, is a matter of debate, but clearly, the buyer MUST do a whole lot of research before committing to their HDTV investment and see through these little bits of misinformation or malinformation!
Worst of all, many buyers now base their decisions on the display when looking at DVD content, and that's just plain wrong. What a 576P DVD output can be rendered on a plasma is totally not the same as rendering a 720p or 1080i video on the same screen. Where DVD is upscaled, HD content is downscaled. Most of the time, visually speaking, Downscaling is much more horrible than upscaling. Where plasmas worked great in the final stand of SD - namely DVD - they suck in HD. Don't take my word for it, check it out for yourself. As before, let me voice some clear messages across:
1) If you're buying a HDTV today, in today's HD-centric world, just KNOW that you can't just compare your screens using the Standard Definition DVD feeds which most of the shops give you. Go download some HD content from the Microsoft WMV-HD site, put it into your notebook and pump the WMVHD full screen into the VGA port of the HDTV you're evaluating. Bring your VGA cable along when you're shopping. From the Display Settings in control panel, make sure your LCD is output in the correct pixel resolution, and check `extend desktop' like this:
2) With LCD TVs so much reduced in price, and quality, a 1366x768 LCD screen should perform much better than plasma display using your test. With the test above, you can also take a look on how your DESKTOP TEXT appears. Text gives away any shortcoming of the display in the most dramatic fashion.
3) In fact, now that Singapore's HD broadcasters have more or less settled on 1080i as a broadcasting standard, with the World Cup broadcasting on 1080i full HD, go for a full LCD TV supporting full 1080i HD instead! Previously I mentioned that these screens are ungodly expensive, I was wrong. I bought one yesterday for under S$3000 and it was .... wow. If I was impressed with the LG L3200TF playing 1080i rescaled to 768 pixels, I was STUNNED by the Amoi 37" LC37AF1S playing the World Cup at 1920x1088 pixels. So it's now possible. Why even bother with the 1366x768 panels? This here is `for the taking!'
4) Don't be misled by the HD Ready label. I realised that if a plasma display can get this label, they must be dishing out those labels like slop in a soup kitchen. In the past I thought that the minimum requirement was that you needed at least to be 1280x720 to get that label, but if a 1024x1024 ALIS Plasma screen can get the label, it's even more irrelevant as I previously thought.
5) Most displays can `take in' 1920x1080 signals - so if any sales guy tell you that a certain TV can take those HD signals, it's almost meaningless. If a screen has a 1024x1024 pixel arrays, when it takes in the 1920x1080 signal, it's going to rescale the 1920x1080 to 1024x1024, which is a 50% horizontal downscale and a 6% vertical downscales. That's shocking. Too much rescale here to be any good. What you REALLY should ask, is ... what's the pixel array of a certain TV. Just to simplify matters, at this time, you should just look for 1368x768 or 1920x1080 pixel arrays - everything else compromises too much on the pixel count.
Looking through many of the `LCD vs Plasma' websites all over the world, I realised that they're outdated. They're looking at all the old considerations, but HD has dealt the finishing blow and put the final nail in the coffin of plasmas - unless of course they release 1920x1080 plasma displays at an affordable price. Until then, bye-bye, Plasmas.
Just an afterword - I'm not a subjective picture quality type of guy. There no method in my madness - I just cannot bear a 1920x1088 signal being shown on anything less than that. HOWEVER, you must note that sometimes, the maxim `what you don't know won't hurt you' might apply. OK, under certain circumstances, if the stream is not encoded well, a high-resolution video with artifacts such as motion smearing, incorrect white balance or color points, and grayscale rendering problems may not look as realistic as a lower-resolution image without any of these problems. Take THAT into consideration, and I apologise in advance for adding such headaches to your already-difficult decision. Read this, it's not wasting time. Sorta it debunks whatever I've written here: http://www.hdtvexpert.com/pages/x1080.htm and he's a HDTV expert, while I'm just a bum.
Let's face it - this is a tough choice. But in view of a sub S$3000 1920x1080 display, it may `relatively speaking' be termed as `disposable' nowadays. It's much of a no-brainer.
Tomorrow I'll post some high resolution camera shots of the World Cup matches.
