What if our universe were a simulation?

The resolution of human vision is something like a maximum of 1000 megapixels (probably less) accounting for integration over several milliseconds in the brain's visual centre of the input from two eyes. Assume colour and intensity can be represented by 48 bits per pixel -- 24 bits for colour and 24 bits for intensity. That means that the maximum number of different images that human vision can potentially ever perceive is (2^48)^(10^9) or approximately 10^(1.4 x 10^10), which is still vastly less than the maximum number of possible brain states 10^(7.8 x 10^41). The images would include every possible thing that any base-level human could ever possibly see -- real or imagined.
 
I wouldn't say worst. Drugs and alcohol exist.

It *could* be worse...that whole sitting around on clouds playing harps holodeck sounds AWFUL.

That said, the planet of the nymphomaniac bacon & whisky addict sex slaves would make a MUCH better simulation.

Is that more then 4k....... All the corporations want me to get 4k because that's the best and they are trying to con me to adapt

"4k" is 3840 by 2160 = 8,294,400 pixels or about 8 megapixels. I think the 1000 megapixel estimate* I quoted is an overestimate as there are only about 6 million cone cells and 90 million rod cells per eye. The cone cells are divided between L, M, and S types for seeing red, green, and blue wavelengths so the effective number for seeing detail could be arguably be divided by three. Personally, I find it very difficult to distinguish between the enhanced resolution of a 4k screen over a 2k screen at a distance of more than two metres. The colour depth of 4k is supposedly greater (10 or 12 bits per RGB channel according to the standard adopted) than 2k (8 bits per RGB channel) and even 4k supposedly doesn't reach the limit of human colour perception. Some TVs have additional colour pixels (cyan, magenta, and/or yellow) to enhance the colour gamut of the screen. The increase in colour depth might be worth the investment for some people and the difference is noticeable to my ageing eyesight but it's not enough to make me want to replace my 2k equipment and media anytime soon.

* The visual cortex does a substantial amount of processing to stitch together a higher resolution 3D picture but I don't really see 1,000 megapixels being a realistic upper limit. Rod cells are used in peripheral and night night vision and are monochromatic. Cone cells are most concentrated in the region of the macula and fovea for seeing fine detail in colour. Some people have four types of cone cell (tetrochromacy) in their eyes and they can probably see many more colours than people with the standard three types.

Thank you for the technical explanation...... But I was being a bit sarcastic regarding 4k and the way tech companies are pushing people to adapt when there is no need
 
Modern capitalism requires consumers to keep consuming so money keeps circulating. The problem is that the technology is approaching a limit where no-one can really tell the difference between upgrades. Between VHS and DVD, certainly. Between DVD and Blu-ray, not so much. Between Blu-ray and 4k Blu-ray, hardly at all. And no-one is really that keen on buying into other enhancements such as 3D, 7.1 surround sound, and 12-bit colour if the stories suck donkey balls.
