My current fridge has some 25 years. Odds are that it'll last another 10 or 20. This is bad from the manufacturers point of view, since I have no motivation to buy a new one. The solution is to either make shitty products that break after some time or to create a product so good with features or parameters better enough to warrant a purchase of a new device whilst the old one is still good.

Improving upon core features is difficult and for many cases is available only to the top names in the established trades. But adding features that sound nice...

The problem is that things like TVs have become way too cheap. We used to be just fine with TVs having a ~20 year life cycle, but that was when a decent TV cost several weeks wages or more. As an example, when I was sorting through my grandmother's stuff after she died I found the receipt for the 25" console TV my grandpa bought in I think 1984, IIRC it was $699 and that was with $100 off since it was a floor model. $699 was a lot of money in 1984, around $2k. Now average TVs are a few hundred bucks for a 50-60" screen.

People are INSANE with the amount they spend on A TELEVISION, every 3-5 years. Need their heads testing :LOL:

It's less about the resolution and more about the DPI.

As TVs get bigger and bigger you need to up the resolution to keep them looking sharp.

There's zero point having a 32" TV that's 8k IMHO.

But if you have a projector making a 3 meter image then 8K is going to look much better than 1080p and probably noticeably better than 4k. (Though i cant say i have seen one yet).


It seems probably we will get to the point where an entire wall of your house is a display. And you can do conference calls that simulate your wall joined to other peoples walls. So its like you are both standing in the same room because the DPI & HDR are so high

My 970 (that's now approaching 8 years old) only has about 30% utilization upscaling 1080p to 4K, about 1 TFLOPS. If we assume the GPU performance required scales linearly with pixel count, upscaling 4K to 8K would require 4 TFLOPS, which an entry level RTX 3050 should have no problems with. (That's also ignoring the DLSS hardware in the RTX GPUs which would accelerate upscaling and make things even easier.)

Photo editing can certainly use more than 4K. Maybe 5K or 6K would be a more reasonable next step, but what's the cost difference between 6K and 8K nowadays?

strawberry:
cant see difference between 1280x720 and 2560x1440 on cellphone only battery usage is different
cameras have to much pixels and it reduces light sensitivity and increase noise and compression efforts
10y ago had Sony Ericsson with same quality camera as new top tech developed recently
