Is 4k a meme?

4K footage on a 2K screen already looks a lot better, thanks to Bayer filter and chroma subsampling.

With a 4K source the difference between a 2K screen and a 4K screen is minimal.
With an 8K source however.....

4k is good for one thing, you can go bigger. That's it that's all

It's a meme in the sense at this point it doesn't really matter that much and if you play games trying to run them at 4k is going to hit your fps hard

Not that much is really in 4k either

At this point it's a whatever I wouldn't waste my money on it thing.

>tfw 65" 4k tv in my living room
>play 720p video games and movies and shit on it anyway and it looks fine

Fuck you for making it so that my dick forces me to make shit decisions on tech.

Garbage. You have to scale up your UI to see anything on small monitors, so you might as well get a lower res. Large monitors are a pain in the neck, the future is x1440, either ultra-wide or multiple monitors.

that green looks twice the light than red and blue.

what am I missing here?

It's how you tell that a panel is energy efficient.

50% of the pixels are indeed green.
25% are red and 25% are blue.

>3840x2160
>4k
lol ok

I still don't get it, shouldn't a white image look green-ish then?

is the brightness on those green subpixels lowered down 50%

are our eyes not capable of seeing green light as much as red and blue light?

>shouldn't a white image look green-ish then?

It does, but for a different reason: sensors are more sensitive to green.
The interpolation takes care of the simple math of averaging out 2 or 4 neighboring pixels.
This is what a raw picture looks like without any processing.

But even if the sensor were equally sensitive to all 3 primary colors, you'd still need to correct for color temperature anyways.
Else all pictures taken in the evening would look red-ish and all pictures taken in the shade would look blue-ish.

do a youtube search for ghost towns 8k. do it, 4kfags

The human eye has less spatial sensitivity to blue/yellow than to red/green. See: color subsampling.

I said no processing, but that image was demosaiced, just not color corrected.

This is a better illustration of how images are converted from raw sensor data to something humans can enjoy.

Anyways, my point is "4K" footage only contains enough RGB data for 2K images. - rest is interpolated and thus will always look a bit blurry.

>Anyways, my point is "4K" footage only contains enough RGB data for 2K images.

Not if the source is 4:4:4

>You sit too far to notice.
Gotta sit closer man. A lot of people still have their TVs at 240i distance or whatever resolution analog had.

no, but you are

Even if the source is 4:4:4
Because of the Bayer filter. (which is what I was trying to illustrate).

A 4K screen has about 8 million red, 8 million green and 8 million blue sub-pixels.
A 4K sensor has about 8 million pixels in total: 2 million red, 4 million green and 2 million blue.

2nd from left is the hottest

Rule of thumb: if you notice ANY improvement in image quality when you turn anti-aliasing on at lower resolutions - for either fonts or gaming - then YES you will see improvement by increasing your resolution you dumb fucking shits.

We're focused on 8k now.

And most video cameras also have an anti-aliasing filter.
Causing even more blur.

UHD is great for porn. You can see the father issues reflect off their eyes in glorious HD.

yes dont fall for it
returning my 4k monitor tomorrow

That's a man (Kaoru Oshima)
But fully agree

I have a 4k 15" laptop screen and it looks fucking awesome. really its badass as hell. some software still doesn't dpi scale and its a bit annoying but the vast majority works fine, 4k on a computer is a lot better than it was 2-3 years ago. I find it especially handy when splitting the screen between 2 or more windows, you can really zoom way out and still read everything

I also have a 4k 39" tv and its also really badass. I can sit very close to the screen, maybe 2-3 feet away and it still looks really sharp. I use it for video watching exclusively because its cheap and only does 30hz at 4k, but it looks great for 4k youtube videos and any other hi-res media. (i tend to play stuff in native res windowed mode if it doesn't go full screen in native res) so the 4k tv really allows me all possible native display resolutions)

That should mean a 4k bayer sensor has more luma information than a 4k monitor can display and slightly less chroma res.

Same amount of luma data.
But it's all fucked up so even B&W looks less sharp. - which is why monochrome digital cameras are still a thing.

Far less chroma information.

Nice kerning, fgt

I really like it. It's not as big of a jump as there was from SD to HD, but I think it's pretty nice.

Even with 50% upscaling there's still a significantly large viewspace. Pic related is a 1080p screenshot on my 3840x2160 desktop. Windows UI has 150% scaling on, but really 125% is totally useable as well.

yes
cause my movie library is 1080p at best and 270p at worst
and if 4k weren´t a meme there wouldn´t be a magical upscaler to make my movies watchable on a 4k tv

DVD's were upscaled before 1080p blu-rays were mainstream
