4K screens RGB vs RGBW
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? -- Alfred Molon Olympus E-series DSLRs and micro 4/3 forum at http://tech.groups.yahoo.com/group/MyOlympus/ http://myolympus.org/ photo sharing site |

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. http://www.hdtvtest.co.uk/news/rgbw-201510084189.htm -- "My Twitter has become so powerful that I can actually make my enemies tell the truth." ...Donald Trump |

Savageduck says... A quick Google search reveals several sites offering explainations, most along these lines: http://visualchillout.co.uk/rgbw-strips-vs-rgb/ I don't think the 15.6" LCD screen of a notebook PC has LEDs for each individual pixel. The R, G, B and W things should be (LCD) colour filters in front of individual pixels. -- Alfred Molon Olympus E-series DSLRs and micro 4/3 forum at http://tech.groups.yahoo.com/group/MyOlympus/ http://myolympus.org/ photo sharing site |

We've got some 4k ones at work used by UX/UI designers and we've had a Spyder calibrator on them and they are extremely good right out of the box. Not sure what the latest line of Dell laptops is like for the panels...
