RIITOP HDSP1T4-4K 1x4 HDMI Splitter 4K@30Hz

1x4 HDMI Splitter for Multi-Display Setups

The RIITOP HDSP1T4-4K takes a single HDMI 1.4 source and duplicates it across four HDMI outputs simultaneously. It supports resolutions up to 4K x 2K at 30 Hz as well as Full HD 1080p and 3D content. Digital audio formats including DTS-HD, Dolby TrueHD and LPCM 7.1 are passed through without loss. The unit is intended for installations such as retail displays, conference rooms or classroom projectors where identical output is required on multiple screens.

Source and Display Compatibility Check

Verify that your source device has an HDMI 1.4 output capable of driving the desired resolution. All four connected displays must share a common supported resolution and refresh rate for stable operation; the splitter cannot downscale independently for each output. The package includes a 5 V DC power adapter with a US plug, so confirm mains compatibility or use a suitable travel adapter. Ensure you have four HDMI cables rated for the target resolution and cable length.

Thermal and Power Characteristics

The splitter draws power from the supplied 5 V DC adapter and consumes minimal energy during normal operation. Its compact enclosure measuring 3.7 x 2.4 x 0.9 inch and weighing 180 g relies on passive cooling with no internal fan, so it runs silently. Place the unit in a ventilated area away from direct heat sources; no active airflow or special mounting is required. The HDCP 1.0/1.1/1.2/1.3 handshake is handled transparently for protected content.
