Dear Sirs,
May it be better, to adapt a smart phone and to configure the machines via Whatsapp as you like, until its battery becomes dead..
We have adapted a "professional" NEC LCD 22" monitor to a machine about two years ago. A few months ago, this display became faulty w/o reason (it was even separated mechanically of the mechanical stresses of the machine), while being absolutely irreparable by the OEM's definition ("New" technologies, or "High-Tech", "LED",.. you know and like such features), and it was rejected with its slide bracket and with the mechanical LPF.
In opposite, CRT monitors work since ~80's, are repaired and refurbished till now even in military applications. Once, our CRT monitor, improperly mounted by a machine owner, has fell down on the machine table. After a broken BNC connector replacing, the monitor was returned on its duty, although this is not a rule.
Again, we suggest to repair your old-, or purchase new/used CRT monitors for this and for other industrial applications, when possible.
We still have new CRT color and monochrome monitors (old stock) which are custom modified for specific applications. We, and other Labs still repair and re-manufacture CRT monitors, replacing even the CRT tubes. In addition, trade-in offers will save you a few money for a spare smartphone battery.

The industrial and far Cosmos will not be conquered with a "green" wind power nor with a "blue" smartphone , but with the "dirty" nuclear power and with the smart people.

Oleg T.
