Distribute two VGA sources to up to four displays in any combination using this 2x4 VGA Matrix Amplifier from Monoprice! This matrix features two VGA inputs and four VGA outputs. Either input can be distributed to any or all outputs. The outputs are boosted using an amplifier with a 250 MHz pixel frequency, allowing it to send signals to distances up to 213 feet (65 meters). It supports DDC, DDC2, DDC2B, and VGA resolutions up to 1920 x 1440 @ 60Hz. Multiple matrices can be cascaded, allowing for both greater flexibility and greater overall cable lengths.
