Re: I want a really high resolution display for reading
I'll give you an experiment:
Render an image at 10Kx10K.
Render the same image at 100x100.
Now scale the 10Kx10K image down to 100x100.
In most cases, the scaled image will look nicer.
You know how FSAA works right? A simple version of 8x FSAA basically goes "render the image 8x larger than it should be, then use intelligent sampling/scaling algorithms to fit it to the screen".
It's why FSAA eats the shit out of your GPU, but it's worth turning on if you can render at a good frame rate. As to whether you'll be buying 2K or 4K movies, well it depends on whether there is anything else. Especially if it's the same price and doesn't come with extra-odious DRM, you'd be a fool not to.
