Adder AV4PRO-DVI-TRI Review
The Adder AV4PRO-DVI-TRI is a triple-head DVI KVM switch for 4 computers and 3 monitors, currently.
This is the three-monitor variant of Adder's modular AV4PRO family, aimed squarely at trading desks and analyst stations running triple-monitor spreads across four different machines. It sits between the AV4PRO-DVI-QUAD (four heads) and a plain dual-head config in price and capability, so buyers should count their exact monitor count before ordering since Adder sells each head configuration as its own SKU.
Purpose-Built for Triple-Monitor Desks
All three monitors switch together as a matched set between the four connected computers, preserving a consistent triple-wide layout no matter which machine is active.
RS232 Remote Control
Like the rest of the AV4PRO family, this model supports RS232 automation for control-room integration alongside standard button and hotkey switching.
Comparison to Alternatives
Versus the Adder AV4PRO-DVI-QUAD, that adds a fourth monitor head, worth the extra cost for full quad-monitor spreads. Versus the Adder AV4PRO-VGA-Triple, that's the analog VGA equivalent, worth it only if your monitors lack DVI inputs.
