Hitachi's 42 1080HD Plasma - Don't buy first
I have been seeing the ad campaign by Hitachi on its new 42 inch plasma which it calls the world's first 1080HD Plasma TV (model number 42PD8900TA). I am very very concerned. My recommendation is not to buy this until there is more research has been done about this product. Why?
Because the resolution is 1,024 x 1080. The number 1080i or 1080p refers to the second number in the resolution description. Now, normally, with a 16:9 aspect ration, the correct resolution should be 1,920 x 1,080 and this is what you find in high end LCD TVs. 1,024 x 1,080 is weired because it seems that although there are enough pixels to cover the width of the TV, there aren't enouhg to cover the length. This could mean that the picture quality will be downscaled with likely degradation by almost 2 times. (1920 vs 1024). My other concern is that 1,024 x 1,080 is like a 1:1 aspect ratio which does not fit the 16:9 ratio that content are created for. This can only mean more rescaling.
I reserve my verdict since I have not tested the screen, but I am very concerned right now. Here's the brochure.

While caution is always good - have you actually seen the Plasma you are commenting on? Further, have you connected a high quality source such as the latest XBox to see what the picture looks like?
I have and in my opinion your alarmist comments are unwarranted.
For Standard Definition material, Full Digital Signal Processing and Scaling ensures that the signal remains pure and clean, while High Quality Digital Image Pixel Processing Technology analyses every pixel in each image signal. Two hi-tech chips work together to handle the process.
First, the new 1080 Progressive Processing system up-scales incoming signals, adding extra pixels to create unparalleled sharpness and detail to our HD ready panels. Then the Super Dynamic Contrast function analyses pictures to enhance picture quality in dark scenes and provide even richer blacks. For HD 1080 broadcasts the new Picture Master HD processor can display all 1080 lines without scaling ensuring the highest possible quality pictures.
In addition, Hitachi Plasma TVs boast 68.6 billion colours thanks to the 12-bit Advanced Digital Colour Management which reproduces 4093 colour graduations. Finally, there’s the High Quality Video Motion processing system, with a High Speed Calculation process which controls every on-screen pixel to avoid any blurring.
While the Singapore 42HD8900TA is not 1080p, that is it can't accept progressive 1920 x 1080, it does a excellent interlace job.
When viewed in context of its price, SGD 5,000 [special at Best, even cheaper at Mega] the set represents excellent value, being cheaper than many quality 720p models.
Evaluate before you comment.
