So, 8K TVs are a big energy-suck! There's a reason why European regulations banned 100% of 8K TVs until the manufacturers undoubtedly paid for a loophole, and now 8K TVs in Europe are shipped in a super-power-saver mode where they consume just barely below the maximum standard amount of power (90w) ... but nobody leaves them in this mode because they look horrible and dim!
If everybody were to upgrade to an 8K TV tomorrow, then I think it would throw away all the progress we've made on Global Warming for the past 20 years ...
