Which means: forget about browsing the web with the Max3 (Android side). Touch scrolling (swipe) does not work as well on EPD (you will miss the PgUp and PgDown buttons) and to add a keyboard just to control web browsing would be "stupid".

EDIT: are you sure it does not at least have a VolumeUp + VolumeDown bar? With that users needing scrolling may be set.

I don't know what you would do with it, but the most important thing in the past history was to overcome the SoloLite, with something fast /and normally featureful/ (do not forget that plenty of software does not work on the "Lite" CPU, e.g. in the context of "Monitor", standard proprietary Desktop Remote software) - which was done - and, achieved that, where would be the advantage of an Intel Core i9-9900K on an EPD based tablet?

Marketing speak should be within quotes. What are those "four refresh modes"? The details there are important.

Now, the problem of the HDMI connection on the Max2 was with the implementation, not really with the lack of good modes, which are extra benefit - once you have GU, which is the requirement (which Onyx excluded and I poked back in).
And those problems in the HDMI implementation were:
-- lack of in-production use features (quick full-screen refresh, quick mode change etc.): you want to have them (and I put those in);
-- wrong resolution: this is not crippling for some applications like text editing, but it is for normal desktop operation and probably most other applications, because the screen becomes blurry while EPD is crisp, which again makes the use "stupid". This was very important, was this solved?
-- battery consumption: that is a heavy problem: what was the source of this, was this tackled? This is akin to another problem, which is using the Floyd-Steinberg algorithm for A2, because it is a non state-conservative dithering algorithm, a heavily randomic algorithm in the visual effect, impacting eyes and battery, while a state-conservative dithering algorithm is needed - was this done?
-- touchscreen: you use a touchscreen device as a monitor, you want to use its touchscreen. The solution found in these pages conflicts with the need of a USB connection (to bring touch data) that, as that USB connection also recharges the tablet battery, drains the power source and stresses the tablet battery - more clearly, on the tablet you want to be able to move data without recharging the battery. The solution must be as battery efficient as possible, in all terms, of stress and consumption. Was this solved?

False. OTG was enbaled in past Onyx products and disabled later (to protect the users against themselves with regards to special battery drain etc.).
