Contrast ratio is a huge determinant of overall image quality, but it can be a confusing specification...

Linus, your description is incorrect. The 3000:1 or 1000:1 numbers you're quoting are called on/off or full field contrast numbers. The scene in which you discuss how the bright city lights compare to the dark background would be quantified by an ANSI contrast or intrascene contrast ratio, not on/off contrast. This is because, most of the time, you'll never actually reach the level of on/off contrast the screen is capable of when you have mixed content on screen. On/off contrast numbers are used by manufacturers because, more often than not, they're much larger than ANSI and intrascene contrast numbers. Bigger is better for marketing and is the same reason they quote screen sizes in diagonal measurements instead of width and response time in grey to grey instead of black to black. The numbers you quote in your video (3000:1 and 1000:1) are full field contrast numbers which are measured when the entire screen is at it's peak white output (white level) versus it's lowest output (black level). For dynamic contrast people should also know that in these dynamic contrast modes there is also something called dynamic gamma which occurs to compensate for brightness compression. If we simply lower the brightness of the light source the image will look dull and flat so manufacturers use some gamma adjustment to make the lighter highlights in the image brighter to compensate for the brightness loss.

This video was really really amazing and informative, and the editing in the background for clarification was awesome, i mean all of your videos are high quality, but this one is special, good job team (y) .

I like the editing in these videos, keep it up! Makes it a lot easier to explain than just having a white screen with someone talking and adds value to the video

I'm glad that you explained Dynamic Contrast Ratio and its different forms, because I had been told in the past that these contrast ratio measurements have been just purely arbitrary from brand to brand, but this makes a ton more sense.

So... i have an old plasma screen TV. I'd assume that it has a pretty decent contrast ratio? It looks pretty good to me.
