RTINGS reviewed the Samsung QN800A as consuming 139W typical, with a 429W maximum: https://www.rtings.com/tv/reviews/samsung/qn800a-8k-qled#tes...

The parent comment is completely wrong on nearly every point it makes. I don't know why it's so upvoted right now.

It doesn't even pass the common sense test. Does anyone really think TVs have 200W CPUs inside just to move pixels around? That's into the territory of a high-end GPU or server CPU. You don't need that much power to move some pixels to a display.

Surely they'd be using image processing ASICs instead of CPUs anyway, hence why they don't draw that kind of power!

I didn't smell anything. A 200W PSU isn't terribly expensive and being cheaper than more efficient processors seems reasonable. I also only run a single 4k monitor so haven't thought about driving 4x the pixels recently.

200W is the realm of powerful GPUs and enthusiast/server CPUs.

Common sense would rule out an 8K TV requiring as much power as an entire gaming GPU just to move pixels from the HDMI port to the panel.

Maybe these TVs are using salvaged Pentium4 CPUs...

And certainly it would require active cooling. TV with audible fans could be a hard sell!
