I think for TVs most people are pretty sensible in using their eyes and not buying into a lot of mysticism and BS.
I disagree. Most people will believe what they see in stores...that's where the problem lies.
Let me explain...
If I go into my local electronics store (Visions, BestBuy, etc.) and look at their TV's, they're ALL doing this:
1. Playing HDR demo videos from thumb-drives, instead of normal content.
For OLED TVs, like LG, they play lots of dark scenes, where there is an item with colour, but the background is black. This emphasizes how good OLED can display black colours. You'll notice that these aren't very bright either. They never play any scenes with light background, since OLEDs can't render colours with very high brightness.
For non-OLED TVs, like Samsung, they play lots of light scenes, where the background is never black, and always bright. This emphasizes the total brightness that non-OLED TVs have over limited-brightness of OLEDs. Of course, this completely ignores all dark background scenes, which non-OLEDs struggle to produce.
2. They enable modes such as "Vivid Picture Mode", which increases the contrast, brightness, and sharpness to absurd levels.
It makes all colours completely fake, but gives it that impressive image....at least to anyone who doesn't understand what's going on.
Another example, walk into your electronics store and then look at the top performing models such as (LG Oled C1), you'll see how awesome they look. Then compare to the next step down model (say LG Oled B1), and you'll see how horrible it appears.
Why?
Because the salesperson probably set "Vivid" mode for C1 and "Normal" mode for B1.
One setting makes one TV look awesome, and another horrible.
They emphasize the higher model, which of course costs more money.
Now, you buy the TV and you bring it home. First, you turn it on and the default picture is the "Standard picture mode", which has a normal contrast, brightness and sharpness. Then you think to yourself...."Man this TV sucks. The store demo was so much better."
Congratulations, you've just been fooled.
The state of TV sales these days is so fake.
Our only choice is to educate ourselves before going shopping for which TV looks the best in store...because TVs in stores are optimized to trick you.
Every time I go shopping for a TV, I bring multiple flash-drives (with 4K HDR mixed content) of the scenes that I know.
Then I tell the sales people to turn off "Vivid Picture Mode" and set it to something I know is more accurate (like the "Filmmaker Mode").
Is anyone else doing this besides me?
I haven't seen anyone else.
The funny part is that the sales people all know what I'm doing when I ask them to do this, and even agree with me, saying this is the best approach.
