The new Sharp LED Quattron TV has 4 colors? How?
 
So I think I may purchase a new flat screen to replace my plasma that is acting up. The Sharp Quattron has ridiculously funny TV ads so I figure its only fair I buy their product. They claim to take the standard RGB and add a YELLOW color. This could be amazing but what if none of my equipment have a RGBY output? I actually dont know of anything that has an RGBY output. Does HDMI have a yellow output? Will anyone be "outputting" yellow or will my TV just have the ability to do something that actually cannot be used?

RGB signals and Component video signals are not the same thing.

In RGB each channel pretty much carries the same image.

Component signal is luma channel combined with chroma channels that carry the color info.

RGB and Component are commonly confused since component cabling and input/output jacks are color coded red, green and blue.

HDMI is digital, bits.

Your computer will send RGB, your DVR, DVD etc... will send component.

Your TV has internal switching to handle the different signals.

My guess is that the TV has a processor that looks at each "pixel" (for lack of the correct term) and says, "hey, this is supposed to be yellow, why don't we throw our fancy yellow dot up!"

Just a small computer inside to determine what'll give the prettiest picture, nothing special about the inputs.

just my guess...

Most digital cameras have two green sensors per pixel

This is pure gimicky crap. The company is just trying to differentiate itself from the crowd. Those tv's look bad because there is no specific yellow channel. The "standard" signal goes through their processor and comes out how their engineers designed it to. You might like it, but this is not what the originator of the content intended.

I have seen the commercials. I have not read any reviews and I have not seen the picture. But I still have an opinion. :)

RGB color is obviously made up of Red Green & Blue. The individual RG&B LEDs have to combine to make the other colors. Yellow is made up of equal amounts of red & green, so both the red & green LEDs fire. Of course to make magenta (purplish color) you have to combine red & blue. To make cyan (blue green) you have to combine green & blue. I can only guess that the red or the green LEDs don’t really make perfect red or green so the addition of a yellow pixel make those colors pop more. I will have to see it to believe it.

RGB is an additive color scheme only works with light. Your inkjet printer put inks on paper in cyan magenta & yellow plus black. But that is a different topic.

Ok so basically, using a digital signal the tv will now know to fire a yellow pixel as necessary. I can see how this could make colors amazingly brighter and clearer. I have Pioneer Plasma from about 2003 that works fine but from time to time the top of the screen has some random green pixels. Can this be repaired?

There is no yellow source signal so it is all created onboard the television. While it makes George Tekai say "Wow!", it is not a great video device.

Early - is the edge discoloration consistent with certain source material or is it random?

About 2 inches from the top of left-ish area of my 50" Pioneer Plasma I get green pixels near the left-center of the screen. It varies based on what the background is displaying.

I don't have any real source of information, but I doubt anything but the most minor of problems can be repaired. There are few repair parts. "Just replace it" is the mantra now.

One thing is for sure, this tv has a great picture and reviews. but I went with a Samsung LED.

But what's really important is whether the volume goes to 11.

only during commercials
