matrix display?

I am interested in trying to link several cell phones displays in a video wall like display
basically i want to take an image of a car dash board and display it across the 4 or 5 cellphones and then actively update information on each display from real time data. things like the speedodmeter and tachometer may actually span across 2 of the displays.
what do you think is the best way to proceed
any hints would be greatly welcomed
ps new at javascript but i’m ok with html

@NogDogNov 13.2020 — My first thought is: why? ;)

Assuming you have a reason, my second thought is that each gets the same, full image, but has CSS that displays that image within a container such that (a) only a portion of the image is visible, the rest being outside of that container and hidden, and (b) each has a different margins for the image (using negative values as applicable) to control which part of the image is displayed on each containing div.

@jrweikleauthorNov 13.2020 — The reason is i need a display that is approximately 7 by 20 the space for it is set and can not be changed

i cannot afford to purchase a custom lcd display so my thought is to use 5 cell phones which will fit in the required area and split the data across each phone. i will have to look at what you pointed me to

thanks

Or a tablet? Seems like one of either of those would be less than any 5 cell phones?

@jrweikleauthorNov 13.2020 — the physical size of the area is 7 inches by 20 inches i cannot modify the area.

there are no 7 inch by 20 inch lcd laptops that i am aware of

the best i can com up with would be 2 7 inch tablets but i would still have to span the two with the single page

I already have the 5 cell phones (used and they cost me only 20 dollars) they will physically work in the area allotted
