Compact 4K HDMI Test Tool

The Monoprice 148143 combines an HDMI signal generator and display analyser in one pocket sized unit. It is built for AV installers and technicians who need to verify sink capabilities or source output on site. The device also works as a display emulator for EDID capture and HDCP handshake testing.

Resolutions up to 4K at 60 with 4:4:4 chroma

A 4 pin DIP switch selects output formats including 4K at 60 4:4:4, 4K at 60 4:2:0, 4K at 30 4:4:4 and 1080 at 60. HDCP modes cover OFF, 1.4 and 2.2 with four test patterns for version verification. LED indicators show 5 V presence and TMDS lock status. The analyser does not generate HDR metadata or test bandwidth beyond the listed formats.

USB 2.0 and 1.1 backwards compatibility

Firmware updates and power draw rely on the legacy USB interface rather than a modern Type C or 3.0 connection. Buyers who need bus powered operation from a current laptop port or automated scripting via a newer protocol should look elsewhere.

Questions about this item

Will the 148143 work with my older 1080p displays that only handle HDCP 1.4?

Yes, the 4-pin DIP switch lets you select 1080p@60 with HDCP 1.4 output so the generator matches the capabilities of legacy screens.

How do I confirm the 148143 is sending a valid 4K@60 4:4:4 signal after I connect it?

Watch the on-board LEDs; they show 5 V presence, TMDS clock activity and the active HDCP mode (OFF, 1.4 or 2.2) so you can verify the signal at a glance.

Does the 148143 ship with a USB cable for power, or do I need to supply my own?

The unit draws power from any USB 2.0 or 1.1 port; a standard USB-A to micro-B cable is required but not included in the box.
