The EU is banning 8K TV's!!!

Shouldn't the screen resolution affect current? If you have more pixels then even if they use zero power to be static, they use power to change. Four times more changes surely means four times more power necessary to change them.

I realise that the power used to change a pixel is very different to the power needed to light those pixels up, but it's still more. Or do the pixels change for free?

When the "more", including the power consumption of the processor needed to crunch all those numbers to convert a digital data stream into an image, is a few percent of the overall, and individual units' power consumption varies more than that because of environmental differences and possibly even differences in the main supply voltage, the "more" is just not significant enough to consider.

In essence, we're talking about approximated, noisy numbers across individual units and use cases here, so a few watts here or there is within the noise, insignificant.

If you compare China to the EU you'll see that China has tripled CO2 emissions between 1990 and 2020 while the EU has reduced the emissions by about 30% in the same period. The real challenge is going to make sure the upcoming countries are going to skip fossil fuels.

Those two things are not unconnected. A lot of the reduction in Europe is simply heavy industry moving to China. Same CO2 emission, different place.

I disagree. A) heavy industry moved to China / Asia during the 70's and 80's. B) If it is due to moving heavy industry, then China's CO2 emissions would have increased by only 30%. The latter isn't the case. What is the primary cause is the increased living standard in China.

Industry didn't start moving to China until the very end of the 1970s, and initially it most mostly light assembly work, especially toys and clothes. That began after Dung Xiao Ping took power in 1976. The really serious moves in heavy industry didn't build up until the 1990s. Europe still did most of its own heavy industrial work until then. I assume you very badly failed maths if you think a 30% reduction in Europe should in any way relate to the percentage increase in China. Not only was their starting point quite different and their population much higher, but they have also developed from a rather poor country, to one with a middle class bigger than the whole of Europe's population. Those people use a LOT more energy per capita than they did when poor.

That is exactly my point!

I am not concerned with whether it's significant or not, just whether it is. When arguments discussions of this sort break out it's important to be correct. It is one thing to say "there's a bit more current due to blah but it's not significant" and quite another to say "there is no extra current used".
