MBP Retina scaling

[odonnelly99]

When you change the rMBP resolution from best "for retina" to either the 1680 res, or the 1920, does it still maintain the same pixel density (2880-1800)?

My apologies if this question has been answered before. I just can't seem to find it

The screen will adjust everything to try to match 1680x1050. It'll look funny though.

This isn't true. It looks good still but performance isn't as smooth. It will still use the full 2800x1800 pixels.

You missed the point. All pixels will be used, but each pixel will be grouped to scale down to 1680...

Yeah, it maintains the same pixel density.

And no, it doesn't look funny. It still looks sharper than a screen with the same native resolution (1680 x 1050).

When setting to to 1680x1050 resolution, the OS X will render the desktop to a 3360x2100 offscreen buffer and then copy/downscale it to the 2880x1800 display buffer. All this is done to prevent visual artefacts due to scaling. The final image is much crisper than a native 1680x1050 panel.

This is wrong. Ore, more accurately - you are right, but the image is rendered at a sub-pixel level so the quality is dramatically improved.
