Doesn’t seem possible to me. I think the record keeping of the move is only by move input on a diagram on all three of the approved electronic scorekeeping devices.
Neither have I, nor have I ever announced it. I have always assumed that the rule is in effect. I believe that you are misreading Mr. Langland’s post. I read it to say that it is only a minor variation. He has certainly never offered anything to support your point. We need to know many rules before we register for a tournament, and all of them before we begin to play. TDs can’t apply different rules willy-nilly throughout a tournament.

The normal entry method is on the diagram. It is done after the move is made on the board. There might be a way to do the entry in scoresheet mode, but I don’t use such devices and don’t know if such a method actually exists.
Having the device go dim (for energy conservation) was seen as having the bonus effect of eliminating a 2-D diagram. The existence of the 2-D diagram of the current position was NOT seen as a violation as then all spectator display boards (which many organizers consider a bonus and which are considered necessary for the top boards at tournaments like the US Open, National Open and US Closed) would be illegal.
I actually tried the Monroi today, and found no way to enter moves on the scoresheet. Perhaps I’m just not very astute. I’ve also used the other two devices, and have never seen a way to enter moves there - in fact to correct a move one goes to the scoresheet, selects the move to be corrected - and then goes back to the diagram to enter it.
So the moves are entered on a blank chessboard diagram; that is, the current position isn’t shown on the MonRoi device?
Or, is it, as below, but isn’t considered a violation?
There never was an assertion that having a 2-D diagram of the position on the device is a violation of rule 20D. Entering a move using the 2-D diagram (and seeing the position that was on the chessboard prior to the player executing the move) is not a case of using a second board for analysis. (How could it be? The player has already physically made the move on the board. And, as Mr. Wiewel has already pointed out, 2-D demo boards are already used at some tournaments to show the games in progress on the top boards.)
In other words, the MonRoi and other electronic scoresheets are designed to work that way. That’s why it was necessary to modify rule rule 15A to require the player to move before recording in the first place.
Writing a move on the score sheet, covering it, & then making the move is one thing. But you are telling me you have never seen a player write a move on the score sheet, cover it, look at the board, erase the written move, make a different move? This would qualify as taking notes, just as writing down candidate moves on separate pieces of paper that were also considered but not played to review for after the game.

A player wouldn’t be able to analyze on the screen unless the device allowed pieces to be moved around on the screen without committing the move.

OK 
OK then
I never suggested anything of the sort. What I meant was that in actual practice this “variation” is always in use. It might as well be the rule instead of a variation. What I also said is that many players using an electronic device also record their move first before playing it. That is a violation, but I have yet to see it addressed.
Generally such players get one warning. The next step is often a two-minute time add to the opponent (this may be the first step). I haven’t yet had to worry about going beyond that.
