Some news about upcoming Onyx devices

Thanks for the reply. That's what I assumed; it's good to have confirmation of this. Looking forward to 4.4 on my K-Pro, and I'm very interested in the new Note!

I disagree. For an Android eReader it's important to have fast processor speed. I have the impression that the Onyx Boox Max 1 browser and other Android apps aren't that responsive. It's good to have a hot coffee on the side.

So a quad core processor is a good thing to have in an e-reader.

Interesting. I did some research and you are right, the algorithm the PaperlikePro uses is called Floyd-Warshall. The PPpro has 3 modes, A2, A5 and Floyd, the latter of which uses the FW algorithm.

Now my question to you is, when does the Floyd-Steinberg algorithm become active on the MaxPro, is there a button for it ?

Also, this is what Nate wrote a month ago on the Dasung Floyd mode : "It's a feature competitors will have to copy or duplicate should they release an E-ink monitor"

Thoughts ? It appears to me , Onyx has taken caren of this ?

I may have misunderstood what Booxtor wrote about it, but in case I did not: have you noticed how A2 works? There exists no unique implementation. Yes, you use the highest contrast per dot, but how do you distribute it? Some firmwares on some devices implement threshold (shilouette), some dithering, some other distributions of blacks and whites in between.

EDIT: maybe this could clarify, https://community.nxp.com/docs/DOC-93396

Thanks Booxtor, because the buttons to turn the pages are unusable in the bottom left part of the device. In the present situation, if you hold the device to read with your two hands, you must release one hand to change the page : SILLY !

I've been waiting for the e-note and max as I was hoping for something with front light in a larger screen. Any news on light? The rest sounds terrific (except for the SD card missing on e Note) Thanks

Anybody else notice that there is a second's delay and then the text appears all at once on the Max2 monitor? Also what if I don't want to clone the display but extend the desktop?

Yes, it was noted*, no, I do not think it is normal for HDMI. But look: to have some insight, why don't you find a video of the latest Dasung, and see if it does the same? It must be the *latest*, third generation - the former were not HDMI. I would search myself, but I currently do not enjoy "video sufficient" Internet infrastructure.
Anyway, lag may not be big problem if mouse cursor is kept local and updated quickly (the EPD screen can do 125ms).

Extend the desktop: that should not be a problem.

*There's a pretty big thread just parallel from here you may have missed.

Here a very good comparison of A16, Floyd and A2 mode in Dasung Pro (the latest)

An input lag of 1 second would be a problem. It's not possible to use a GUI with that lag.

That's great, Desk7! Unfortunately, I will not be able to check it until Sunday. Could you please reveal if the delay is there or not, in Dasung's HDMI based system? If it is there (I doubt), there is some bottleneck I do not understand with the technology. If it is not there, there is an error in Onix' presentation in Tw.

It is possible to use a GUI, if the mouse is updated almost instantly.
You can do that e.g. using remote desktop with local mouse pointer rendering. (Or you can go fully touch.)

Yes, if the mouse is updated instantly it works.

Ok, I managed to see a low resolution version of the "Full Review, Part 1".

The "Normal" mode works much, much better on the Max Carta (repeat: *on* the MaxCarta). On the Dasung it has the same "occasionality" in displaying the mouse cursor than I am seeing on the latest Icarus/Boyue. I am sure that is a bad configuration.

The "A2" mode on the Dasung is implemented badly: again, that is using threshold instead of dithering. That is not a good implementation of A2. Freescale/NXP implemented it right in 2012, and on the MaxCarta (re-implemented, apparently) it does it job amazingly.

The Floyd mode: I cannot download the high quality video - too bad as I would only need one frame -, but given how it behaves, is it possible that it is an "A2 with (Floyd?) dithering" mode? Can anybody check (maybe through `youtube-dl` or similar) if the images in the "Floyd" mode use 16 shades or dithered black and white?

EDIT: also: I loaded it in a video editor, I see that the A2/Floyd mode is still 8fps (125ms), no revolution there. On other Dasung videos it seemed much faster. Checked on the mouse cursor update at seconds 8:06 and 8:07

The video gives no possibility to verify any lag between traditional monitor and Dasung. I see that desk7 asked directly to the uploader if he could divulge.

20 frames over 25, ~800ms delay.
It looks worse, but it is not enormous (some EPD modes have a 600ms lag).
