Quoth and his wisdom again I'm sorry, but you're kind of particular guy who sounds very convincing but ...

The 90tish % of "matte" screen protectors are only diffusing the light inside but have a high gloss finish. You can easily see it looking at an angle.

Sure, the amount of reflected light is a sum of light reflected from the surface of the screen + light reflected from the bottom reflective layer of the screen. However, the approach taken by the majority of the "matte" screen foils is dumb, they only aim to reduce the deep reflected light which makes the image dull but still expose light reflection from the surface

Then that's a diffuser, not a matt cover. Matt ONLY applies to a surface and can be measured.

Describing anything at all of any nature as a "matt" when it has a high gloss finish is simply either a lie, or the marketing department doesn't understand English.

No doubt someone makes a matt screen protector, because you could retrofit matt filters on CRTs 40 years ago. But I have not yet seen a matt screen protector for a phone or tablet. Some are tinted, but that isn't the same thing. A polarising filter can reduce reflections from a screen, but unless its surface is matt it's nearly useless on a phone or tablet as the surface will reflect.

Plenty of screen protectors are advertised as matt, but they aren't. Obvious even from photos on web pages.

I see your way of thinking. We were talking here about "matte screen protector" as a product name on the market. 90% of them are not technically matte.

Well, I only read all of this thread AFTER bying my NXT Paper 11 a few days ago. And this is my first post after a long time being away here.

First of all I am amazed by the reading experience this tablet is giving me. I have been looking a long time for an Android tablet with a good reading experience and a big battery.

I don't understand why this tablet is only mentioned in a few threads here since it came in the market a couple of years ago.

But now I have taken the backup of my Android phone. Saying that I am not interested in games i.m.h.o. it performs ok in all the other things i use with my phone.

For not even 200 Euro's this is an absolute bargain and I don't see myself picking up my Kobo again.

Set colour mode to sRGB and custom White Balance, nearly centre the control in the colour wheel because the colour temperature setting tints bright greys but doesn't affect white.

If the brightness is just enough then it looks very like eink. Except eink is reflecting so the white balance always is identical to ambient. Unfortunately the white balance software is flawed on the Nxtpaper 11, so neutral is best. That will look warm in some ambient conditions and by tungsten ambient or very warm colour temperature LED it will look cool.

Finding Dark mode better suggest the brightness is too high. Also black text on white paper (or dirty colour of PDF scan) is sharper on a colour display than white text on black.

Also "Dark" mode is only going to work properly with pure text. No use for scanned PDFs or Video etc.

Hey, I've finally decided to give Nxtpaper 11 a try(and still have few days left to return if I won't like it). So far Nxtpaper screen is pretty good and device itself is interesting albeit as you said before, there are obvious flaws like dimensions and aspect ratio.


Anyway, reading your post above I'd like to ask about optimal settings for reading, my current ones are:
- NXTVision enchacements(Image, Video Game) on. No idea what they do, should those be off?
- Reading mode off. This one seems to be just basic BW monochromancy mode available on almost any recent android device in developer options.
- Eye comfort mode off. This one is probably just software color tint commonly available on most devices.
- Sunlight display mode off. (Do you know what does it do? It says it "Increases readability under sunlight" but after tests I can't tell the difference.)
- Color mode & temperature set to advanced and default sRGB(dot directly in center of color wheel).
- Gamma 2.0(Sharpness).


I found that NXTPaper is not good in direct sunlight but given it's mobile device, it's possible to just move around to find darker spot and with maxed brightness visibility gets bit better(just using own body to cover the sun is making huge difference - black screen vs poor but visible text).

Also found that lowest brightness(2%) is probably bit too bright for completely dark environment but software light dimmers are good workaround.


I still don't know does TCL NXTPaper 11(NXTPAPER 2.0 screen) use PWM or not. According to data from TCL website DC Dimming was introduced with NXTPAPER 3.0 but I've done some testing with camera and couldn't find any PWM, even at lowest brightness. But then I've found some online people claiming they tested NXTPAPER 2.0 with professional tools and it does have PWM which is especially visible at 50% brightness or lower. Confused here...

Also wondering does NXTPaper 11 use Temporal Dithering and if so, is there any way of disabling it. Perhaps there's some relation to NXTVision enchancements?
