VGA Splitter 4 Port 1×4 250MHz 1920×1440 Video Distribution Box with EDID

Multi-Display Analog Video Distribution

The VGA Splitter 4 Port duplicates one analog RGBHV source to four displays without a second graphics card. It accepts a 15-pin HD15 input and drives four HD15 outputs at up to 1920×1440 at 60Hz. A metal enclosure suits shelf, wall or under-desk placement in meeting rooms and control cabins.

Video bandwidth reaches 250MHz at -3dB, which passes UXGA and QXGA signals without visible smearing. Input level runs 0.5 to 1.0V p-p on the RGB lines, and the H/V sync channel accepts 0.7 to 5.0V p-p. Output gain stays at unity, so brightness and colour balance hold across all four ports.

A DC input of 5V to 12V powers the buffer amplifier, and the supplied adapter drives four outputs at once. EDID handling reads the display on output 1 and mirrors those timings to the remaining ports. The chassis measures about 130 x 75 x 28 mm and operates from 0°C to 50°C.

Key Features

• One Input to Four Outputs
  A single HD15 source feeds four monitors, projectors or capture devices with identical video timing.

• 250MHz Video Bandwidth
  The -3dB passband carries 1920×1440 at 60Hz and 2048×1536 signals without perceptible edge blur.

• Signal Level Handling

  • RGB input 0.5 to 1.0V p-p
  • H/V sync input 0.7 to 5.0V p-p
  • Unity gain on all four buffered outputs

• EDID Mirroring
  The unit samples the output 1 display and applies those timings to the other three ports.

• Metal Chassis
  A shielded steel case limits radiated interference from the amplifier stage inside crowded AV cabinets.

• External DC Supply
  A 5V to 12V DC jack powers the buffer, and the bundled adapter covers all four outputs under load.

• Bandwidth-Limited Cable Runs
  Short HD15 patch leads at each port keep total run length inside the 65-metre guidance for 250MHz hardware.
