thanks for the videos. Touch function in VNC looks handy.

I’m still seeing the errors I reported earlier with the HDMI function though. If no one else is, then perhaps my unit is faulty.

Or. I suggest you post details about the Mac you are using, so other people with that model can confirm.
(I would also suggest that you try with other devices if they are available.)

It’s a 2017 MacBook Pro. I did try other things, including other devices (as described in https://www.mobileread.com/forums/sh...8&postcount=53)

I tried two different HDMI cables (I happen to have a spare micro HDMI cable for a graphics card), with essentially anything I could find with an HDMI output:

Raspberry Pi 3, Mac Mini (both with macOS and Windows), PS3, and the aforementioned MacBook Pro.

EDIT Oh, and an Apple TV 4th gen

Here it is:
EDIT: I am having a problem with the forum engine video function... Here is the link:

https://www.youtube.com/watch?v=RCoN5kehPqs

«[...] the beginning of Machinarium from Amanita Design, as viewed from HDMI.»
On the previous videos, Onyx had a huge time delay of 300 milliseconds, which is much more than that of Dasung Pro. Playing games with a delay of 300 milliseconds is simply impossible. It's not about the frame rate. I mean the delay that is felt when moving the mouse, moving windows, etc. If the time between pressing the button and the corresponding action on the screen is too large, it will be agony.
You can show simultaneously Onyx Boox Pro and LCD display (in mirror-mode), so we can estimate the time delay? I want to see how much Onyx lags behind the LCD display.

Where did you get the data for the Dasung? We searched and found nothing.

Not really, it depends on the type. And I picked games, after the joke from Fgdas, to create an empirical scale, like "diamond to talc". So, as you have read in the other thread, "Cuphead: impossible; Braid: doable; Machinarium: no problem".

Of course, who supposed that? But actually, that's not entirely true, in some situations you may miss a two or four extra frames to be wedged in the period (a brief check on New Vegas ).

If you want proof, no problem, and I can post a zipped mp4 here - but why don't you just ask directly for the data.
For what VNC and TV are concerned, I counted and I can tell you that the lags are sometimes around 0.33s, or 0.5s, or 0.67 s (~10f, ~15f, ~20f on 30f/s), depending - and this using the VNC embedded in VMWare, since as you know x11vnc has a structural delay on its own because it is not integrated to the system to know that some parts of the screen have changed - it has to check.
Oddly enough, the delay is inconsistent - sometimes the shorter, sometimes the longer (move a window, move it again, close the window etc.).
For what HDMI is concerned, I did not even try. And one of the reasons is, it will give you a theoretical value that you cannot fully match with practice. Really, you already know that the delay is not negligible. At that point, to determine that 200ms is good and 400ms is not would be arbitrary. You have to try.
To what I experienced, the HDMI speed would be good for normal desktop use, not to test reflexes. To my experience, it seemed speedier than remote desktop. But do not forget that the shipped HDMI solution, the 'Monitor' software, currently forces you to A2 and has massively unoptimized dot state conservation - it is at least one revision far from competing with remote desktop alternatives.


EDIT: maybe the SDK has the access to the HDMI port, are you in to try developing a custom solution ; ) ?
('Cause I am not sure we can contribute code for the original 'Monitor' application.)

I am sorry, but in this phase I cannot test mine with a good amount of devices to give you data on the reliability.
It would be helpful if other users posted here their rate of success in connecting the Max2 to an HDMI source.

Me, as I said, I experienced it mostly working immediately at first attempt but for a few times, failures which I expect. But with a single graphics board source.

So, I just shot a video and checked. On retrospect, I should have shot at 50fps, but anyway.
I can tell you that the average delay I get is 250ms, with little deviation (owing to the gross discretion).

So tried shooting high speed video, and then realized there were caveats...
So I got this idea: this is (close to) the video you want.
Again, measuring here is not perfect, but I checked a few points of the video and got an average of ~300ms. Sometimes less: see below the screenshot...

@mdp do you think that a software update from Onyx would/could bring down these 250 ms delay?

I don't know, find official information for the minimum refresh time for EPD in general, and maybe ES133TT3 in particular, then we go on talking.

Surely, you do not get anything better than HDMI to carry the data.

The Monitor application has to add features (or maybe reconsider its workings - with reference to the problem of the unneeded re-rendering of static parts), not necessary become slimmer.

@mdp did you manage to train a neural network on Max2?

I don't know what tools are you using but could you check how Termux app works on Max2?

I would love to use Max2 for some simple coding with Python and Numpy without remote control or hdmi..

Wrong thread ; )
Anyway, I mentioned that after receiving the product because I know that Octave runs on Android. And of course it does on the Max2, see screenshot.

But I remember that Fabrizio asked about using python on Onyx tablets, and I believe that the request remained unfulfilled. The mention of termux, and possibly of Gnuroot, should go there. Also considering that maybe he now solved the issue and has pointers.
Let us keep this thread related to general monitor functions.

Hi. first post on this forum.
I'm the maker of that youtube video with macro-lens.
I made such video for experimental purpose Without the information that the people in Europe had been possible to get Max2.
I got Max2 in 6 Dec 2017, that time there was a little information about Max2 in this forum. I was busy that time and forgot to follow this forum.

I have 2 questions.

1: In my case, windows 10 give me the resolution 2104x1560 through HDMI connection. who can get the resoluthin 2200x1650 through HDMI connection?
I guess this is windows 10 driver problem or Max2 chipset problem.
( I used Max2 as HDMI Monitor in last Decenber, Max2 kept My eyes well :-)

2: I have searched RemoteDesktop applcations (include VNC) which is possible to transmit pen puressue, some information suggest Windows RDP is possible. But I have tested and failed. ( Android application is not possible? ) do you know such protocol?

I want to use Max2 like Wacom Cintiq Companion Hybrid.

I get all standard resolutions from NVidia Control Panel. But I cannot test on the OS you indicate.

Have you tried both Iordanov's aRDP and MS' own solution (com.microsoft.rdc)?

Googling for "remote desktop pressure sensitivity" returns too many results, but you have to spend time on the search - it is not immediate. Anyway, I will open a GitHub "Issue ticket" with Iordan to note the interest about delivering pressure sensitivity through the client.
EDIT: the ticket is now open.

EDIT2: a less quick check seems to reveal that many searched for pressure sensitivity in VNC products, that MS in even recent stages did not implement it in RDP and that TV did not support it either not long ago.
So, your best strike of luck could probably be that Mr. Iordanov gets intrigued ; )

It is not clear what you mean as you mention the "Android application".
