MARCH 2020 MACWORLD 31that about most every piece of non-Apple
equipment, though. Samsung includes a
VESA mount adapter with the CJ791, but the
display ships with a round stand.
The external 24-volt power supply
supplies 85 watts to the various ports, and
indeed, the 2017 MacBook Pro used for
some of the testing said it was charging
while plugged in. My phone charged on
the USB port and there were also no
issues with any of the input or storage
peripherals I attached.
There are two speakers on board, which

connecting peripherals are also included.
You can also leverage more than one

by-Picture (PbP, 1720 by 1440) and Picture-
in-Picture (PiP, 720 by 480 up to 1720 by

display between two sources, or with PiP
devote one quadrant to a second source.
The plastic bezel and stand are silver,

The overall appearance, comparatively, is
just a tad, shall I say, less expensive than
Apple with its metal casing. You can also say
