Must have accessories for improved system performance

@soix  You hit the nail on the head. The system should allow one to forget about the objective qualities and instead get "lost" or immersed in the sensory experience itself. That is what it's all about, right?

Back in the day I remember my Pioneer plasma at 768P resolution being vastly preferable to any of the newer LCD displays doing 1080P. The rich, deep black levels, uniform backlighting, and superior motion handling far outweighed any issue with pixel density.

I feel the same way now with 4K OLED being by far preferable to any 8K LED out there. Although LED has certainly come a long way since the old LCD days, particularly with the microLED technology, I think pretty much anyone would prefer the inky blacks of OLED over anything else. 

I'm not sure what this thread was really supposed to be about or if this post is in the right context. If not, sorry.

'@v-fi  I was inquiring into system performance. 

I appreciate your comments:  "rich, deep black levels, uniform backlighting, and superior motion handling far outweighed any issue with pixel density."

If a new technology was available to improve performance and enhance the experience would it be of interest? In other words, can the video image of any available technology (plasma, LCD, OLED) be improved?  Aside from power supply improvements.

I'd highly recommend getting your display professionally calibrated and then add a good power and HDMI cables.  As with audio it makes a difference.

There are about forty adjustments to the color, contrast, and other parameters of a TV. I used to work for Sharp. So, I had a professional product design guy... give me the "perfect settings"... it was like +1, -8, +31, -8, 1, 5, -8.... on and on. 

It is virtually impossible to actually evaluate the picture quality unless you can compare carefully calibrated monitors. We had a whole room of every brand you can think of, and our Aquos... these guys analyzed the picture of our competitors. 

Typically in the showroom they are set to DEMO. Because, showrooms are bright. and people react to intense colors... so, in this mode they look horrible at home. Then when home they have movie, and sports, and a couple other high level settings. But under advanced... there are dozens of adjustments... so the only way to get the most out of your TV is to get it professionally adjusted. Meaning... you probably need to choose a brand from professionally compared TVs or you are going to be comparing apples and oranges because of the settings.
