educate me - is there a description of the shift technology optima use - mechanical(dlp) or 'electronic'(e-shift) there are only a few ways to skin a cat, so to speak,
otherwise why is the differences not down to image processing to prepare the input to those two basic technologies.
The difference is related to the independent single pixel structures that allow 2 pixels per mirror and the discrete pixels. The e-shift projectors mentioned before do not display the full 4k discrete pixels and they have large overlapping pixels. The Optima doesn’t have large overlapping pixels but displays the full discrete pixels at the correct size. Discrete being the key word as that is what is allowing the Optima to do 1:1 pixel mapping and pass.
The funny thing is after I describe how some sites are being deceitful Vila goes straight to one of those sites and does the same deceitful thing himself. That says a lot about him.
I bring this up as it’s related directly to the difference in the methods. In that link Vila posted this morning they said eshift projector do not count as 4k due to large overlapping pixels and not being able to display perfect vertical or horizontal line, that’s 1/3840 of the screen width. They then mention how 1:1 pixel mapped test patterns failed to display correctly which is all true. Even though Vila lied its clear none of that applies to the optima which has the correct sized none overlapping full 4k discrete pixels and passes the 1:1 test pattern and displays the perfect vertical or horizontal line.
While Vila likes to say he has posted lots of reviews & tests they are not valid if you read and understand them. He keeps posting evidence from projectors based on the eshift method with large overlapping pixels. For example he said
“they even test one and say it didn’t pass a one pixel wide colour change test”
That’s just Vila being deceitful as when you look at the difference in methods you see the evidence Vila posts only applies to the eshift projectors with large overlapping pixels and not the Optima. Those failed test patterns and failed perfect vertical or horizontal lines where not run on the Optima but the already established e-shift projectors which use a clearly different method.
The key difference in methods is.
Optima display the full discrete pixels and pass’s the main 1:1 mapped test patterns.
Overlapping large pixel E-shift projectors do not display the full discrete pixels and do not pass 1:1 mapped test patterns.
Optima has no large overlapping pixels and can display each individual pixel in a perfect vertical or horizontal line, that’s 1/3840 of the screen width.
Overlapping large pixel E-shift projectors have large overlapping pixels and cannot display perfect vertical or horizontal line, that’s 1/3840 of the screen width.
Optima has the full 8.3 million individual pixels on screen for true 4k.
Overlapping large pixel E-shift projectors have around 6 million individual pixels on screen vastly short of true 4k.
Clearly they are very different methods and vila so called evidence based on Overlapping E-shift projectors doesn't apply to the Optima.
Like Vila a few websites out there do not understand the difference between Optimas method and the Overlapping large pixel E-shift method. Some of the websites wrongly assumed the Optima runs in the same way as the Overlapping E-shift method and wrongly assume the Optima has the same problems as the Overlapping E-shift method. Which is why when Vila lied and said some things are impossible on the Optima it was really very possible.
Posting links to those websites proves nothing apart from those websites do not know what they are talking about.
