Adder Technology Adder ADDERView PRO vs J-Tech Digital JTECH-DKM21-8K: which one fits your build
The Adder Technology Adder ADDERView PRO suits budget-conscious desks needing basic isolated switching between 4 DVI machines and legacy DVI workstations that haven't moved to DisplayPort/HDMI, though it is not the pick for users needing simultaneous multi-screen viewing (see the CCS-MV4224) and modern DisplayPort/HDMI-only hardware. It is the wrong buy for desks requiring formal NIAP/Common Criteria certification (see the Cybex SC800 line). Buy the J-Tech Digital JTECH-DKM21-8K for Dual-PC desks sharing one high-refresh or high-resolution monitor and users who want DisplayPort 1.4 bandwidth for 4K@240Hz or 8K@60Hz, though it is the wrong buy for setups with more than 2 source computers and HDMI-only computers or monitors (DisplayPort only). Our rating of the Adder Technology Adder ADDERView PRO (7/10): an affordable way to add isolated switching to a 4-port DVI desk without paying for certification or multiviewer features.
