I was checking a new notebook (the ASUS VivoBook Pro 15 N580VD). Looks
interesting, especially because the price is not so high compared to
other notebook PCs in the same class (core i7 7700HQ, 512GB SSD+1TB HDD,
16GB RAM, 15" UHD screen, fast graphics card etc).

But the 4K screen seems to be only RGBW and not RGB, which according to
a review degrades a bit the image shown on the screen. Does anybody know
more about this RGB vs RGBW issue?


From a cursory review it does indeed seem such displays (RGBW) are not
as good as pure RGB in terms of colour reproduction. They may be a bit
better in brightness. They are cheaper to make.

This does not seem like a machine a photographer w/should use. OTOH, if
you go look at one in appropriate lighting conditions and find it
acceptable, then that may be sufficient for you.

This notebook was ticking all the boxes, until I read about the RGBW
issue with the screen.

Which other 15" notebook has a decent 4K screen for image editing?

I would need a machine as fast as possible (which in practice means an
i7 7700HQ or similar processor and a fast graphics card), 16GB RAM or
more, M.2 SSD and HDD for space.
