Arrow LG releases "fake" 4K UHD TV

Quote:
A new entry level 4K Ultra HD LCD TV line LG Electronics dropped in the U.S. market two weeks ago has started to create a stir over how to define 4K UHD resolution.

LG’s new UF6800 LED LCD TV series, which includes 55- and 65-inch screen sizes, features a controversial new LCD panel that uses a white sub-pixel, along with the standard Red, Green and Blue (RGB) sub-pixels that make up each pixel, in order to produce a lower-cost 4K Ultra HD LCD TV.

Critics, who contacted HD Guru about the new sets, say the additional white pixel reduces the number of RGB sub-pixels in the 3840 pixel count across the screen, and the set therefore fails to comply with the Consumer Electronics Association’s (CEA’s) terminology for 4K Ultra HD minimum performance attributes...

Same BS started when HDTVs first went on sale. The CEA said there were three definitions for HDTV:

1920x1080P
1920x1080i
1280x720P

If your pixel count was less, then you couldn't call it an HDTV. This was prompted by the introduction of 1024x768P displays.

They shouldn't release incomplete standards, as it only confuses the consumer, and delays adoption.

Professional reviews of displays are an excellent tool, but the final decision should come from using your own eyes.

The standard for UHD had already been set. It's pretty simple:

3840x2160P

16x9 aspect ratio.


Those are the minimum specs you have to reach to call your TV a UHD TV.

All LG is trying to do is to come up with a cheaper to manufacturer panel so they can undercut their competition. But by adding the white pixel, it reduces the hortizontial resolution to below minimum UHD specs.

Where the real confusion is, but doesn't seem to affect anything, is the use of the "4K" moniker when it comes to UHD products. For consumers, there are no specs that reach 4K. 4K (4096x2160) was adopted by the Digital Cinema Initiative as the format to replace 2K (20481080). The reason why DCI resolutions are higher than consumer versions is because DCI uses an aspect ratio of 1.85 vs 1.78 for consumers.

One of the features that can be added in the future as provided by HDMI 2.0 is changing the aspect ratio of UHD from 16x9 to 21x9. This would result in a resolution of 5160x2160 (5K). So far, 21x9 TVs have not done well in the marketplace and there is no reason to think they will when going from HD to UHD. All the problems and issues are still there that made them fail in the first place.
