iirc, ang mga 50in plasma few years ago, resolution nila is 1366x768. Ngayon kahit mga 50in, if not full hd, 1024x768 na din. I wonder why, cost cutting?
Looks like Panny wanted to limit it to 2 resolutions.
They used to have 2 resolutions: 852 x 480 (EDTV or "Extended Resolution TV") for 42"; and 1366 x 768 (WXGA or "Wide Extended Graphics Array") for 50". Both of them are 16:9 pixel ratios.
Next, they phased out the 852 x 480 for the 42" and replaced it with 1024 x 768 (XGA or "Extended Graphics Array"). This time, they had 3 resolutions: XGA 1024 x 768 (42" only); WXGA 1366 x 768 (50" only); and Full HD 1920 x 1080 (for all panel sizes).
I think it was in 2010 that they phased out the 1366 x768 resolution and also replaced it with the 1024 x 768 resolution. So now, Panny plasma resolutions are cut down from 3 types to the 2 that we have now: XGA 1024 x 768 and Full HD 1920 x 1080. Both resolutions are available in 42" and 50" sizes. But any panel size larger than 50" always comes with a Full HD resolution.
=============================
For panel sizes larger than 50", you'd think that resolutions have nowhere to go but up. ... Not.
Surpisingly, in 2012 Samsung came up with two 60 inch plasmas that are not Full HD --- the 60 inch PenTile panels of the 60E550 and 60E530. It's more power-efficient, but expectedly produces an inferior picture. What's more puzzling is that Samsung won't even tell us what the resolution is. All they're saying is that it "reproduces FHD-like experience."
http://ramsaysmarthomes.ca/info/Samsung%202012%20Panel%20Chart.pdfThe footnote reads:
*Samsung’s Pentile Panel reproduces FHD-like experience utilizing sub-pixel rendering technology, making it 40% energy efficient over last year’s 59” comparable model.http://en.wikipedia.org/wiki/PenTile_matrix_familyI've searched all over the net but I can't find any info as to why the pixel structure on the Panny X50 is different from their older 720p plasmas. Maybe it's because no enthusiast seems to be interested in those low-end models.
I don't know if the Panny X50 is using PenTile displays. It's a theory I have, but so far, I haven't found anything to back that up.
