Samsung TabPRO 12.2, 10.1 and NotePRO all have PenTile displays, but not TabPRO 8.4
It looks like the only new Samsung tablet in the PRO series without an alternative PenTile pixel matrix screen would be the smallest one, TabPRO 8.4. We already saw that the TabPRO 10.1 carries a PenTile RGBW arrangement of its panel, and our own macro lens shots of the NotePRO screen that you can see in the slideshow below, indicate the same RGBW PenTile arrangement is in store. Press the 100% zoom button, and you will clearly see the RGBW arrangement.
Given that the Galaxy TabPRO 12.2, the NotePRO, the TabPRO 10.1 and TabPRO 8.4 all sport 2560x1600 pixels screen, it is all the more impressive that the the smallest of the bunch turns out to be the only with a standard "stripe" RGB matrix, perhaps on account of a new technology Samsung had to use for cramming four million pixels in such a small size. That would indicate true "2K" sharpness of the tiniest display in the lineup, and a sight to behold, considering it also flaunts the highest pixel denisty on a tablet - 360ppi.
With the larger tabs, on the other hand, that crazy resolution is achieved with an alternative pixel matrix arrangement that looks like a checkered pattern when you examine solid colors up close and personal. Not that this changes the viewing experience at such high pixel densities, but if you get the TabPRO 8.4 it should warm your heart to know you are getting a real sharp 2K screen, and in an 8" form factor, too.
