RGBA sucks

There are (assuming 8 bits per colour) 2^24 combinations with full transparency. This is even worse than https://dis.tinychan.org/read/prog/1457531769

I agree
HSV is better

Oh noes, they wasted almost a half percent of the colorspace!

Don't assume my anime color depth. Its 10bit

They create different edge/scaling/motion effects, depending on color of "fully transparent pixels"

How does it work?

In Farbfeld, pattern resolution is not done while converting, but while compressing the image. For example, farbfeld always stores the alpha-channel, even if the image doesn’t have alpha-variation. This may sound like a big waste at first, but as soon as you compress an image of this kind, the compression-algorithm (e.g. bz2) recognizes the pattern that every 48 bits the 16 bits store the same information. And the compression-algorithms get better and better at this.

Fartfield is a joke.

https://en.wikipedia.org/wiki/Rec._2020
http://www.dell.com/learn/ai/en/aicorp1/secure/2017-04-20-dell-announces-new-hdr10-monitor-with-uhd

Displays with 80-85% of Rec.2020 this year, but they cost $1800-$2200 for 27"-32".

10-bit and 12-bits per color channel depending on the technology (image buffers have 16-bits per color channel, either 16-bit unorm or 16-bit floating point for HDR rendering).

So granted that money is not a barrier, what would you prefer of the following?

1440p 100% Rec.709/sRGB 144Hz TN/VA gayming?
4k 85% Rec.2020 8ms GTG 60Hz IPS professional?
Both?

I choose a $200 Sony WEGA CRT.

What's the monitor size though?

I'm using two $400 dell U2415's right now, but wondering if this modality is becoming outdated and a single 4K 30+" monitor would be better.

>>13
If it's 4K, you probably want to go no smaller than 30"

Sounds a bit large.
I rather get more horizontal space than both

Don't change these.
