There lies the problem. This shouldn't be about disrespecting someone or not. It should be about getting down to the truth of what is happening. We should question everything and not just take someone's opinion as fact just because they are a so called "Expert".
The whole 4:4:4 issue is that the test pattern they are currently using can cause a failure for multiple reasons(Bit depth, 1:1 pixel mapping, and 4:4:4 non-compliance). There is no way to know which one of the issues is the problem because that test pattern tests for too many things at once. Some of those things are big issues and some aren't. If a TV is truly 4:2:2 or 4:2:0 it is extremely obvious with a computer hooked up to it. You don't need a test pattern to see it.
The reviewers are incorrectly diagnosing this as a 4:4:4 issue when it isn't. The danger there is that the real reason that the Vizio M-series fails their test is only evident with that particular test pattern. You can't see any issues with anything but that particular test pattern. Do you want to make your TV work with everything you use or one particular test pattern?
The issue with 4:2:2 and 4:2:0 is that the reduced color information causes discoloration and rain-bowing around text. This discoloring is very obvious. It doesn't take a specialized test pattern to see it. Any black text will show the issue right away.
I am not asking everyone to take my word for it. I want you all to test it yourself. Hook a computer up to your TV with an Nvidia graphics card. Then try the 4:4:4, 4:2:2, and 4:2:0 options with your background, with text, with your browser. Test it with everything except for that particular test pattern. See if you see the difference between the 4:4:4, 4:2:2, and 4:2:0 options. Then compare the 4:4:4 option in the same manner to a monitor that you know is 4:4:4. See if the Vizio TV exhibits any of the issues that you saw with 4:2:2 or 4:2:0 when compared to the 4:4:4 monitor.
If the test pattern is the only thing the Vizio fails why are we so caught up with that? The biggest issue here is that no one seems willing to challenge the establishment. If someone comes out and simply says the Samsung is better people here are much more willing to run with that than someone who shows evidence to the contrary. It shouldn't be that way.
I just want everyone to question everything. Question me, question the reviewers, and question the established tests. Some of them are correct and some of them aren't. It is our duty to do our due diligence and find out what the truth really is.
