For a monitors projectors setup, the core decision is whether you need to send one 4K HDMI signal to several screens at once or carry that signal from one source to one display. The onn. 4-Port High Speed 4K HDMI Splitter and the Monoprice 4K High Speed HDMI Cable sit on opposite sides of that question, with listed prices of USD 19.50 and USD 85.54 respectively.
Quick verdict
If you want one HDMI source mirrored across multiple HDTVs, monitors, or projectors, the onn. 4-Port HDMI Splitter is the route to choose: it accepts one input and sends it to four outputs. If your need is a straightforward point-to-point connection between a 4K source and one display, the Monoprice 4K High Speed HDMI Cable is the single-cable choice. The splitter is the lower-priced item, but it cannot replace the cable's role in linking two specific devices at a distance, and the cable cannot duplicate a signal across four screens.
Comparison at a glance
| Product | Listed Price | Price Bar | Core Role |
|---|---|---|---|
| onn. 4-Port High Speed 4K HDMI Splitter | USD 19.50 | One HDMI input to four outputs for HDTVs, monitors, and projectors | |

Where each product wins
The onn. splitter wins when the job is distribution. Its 1:4 split means one source can feed four displays simultaneously, and its universal brand compatibility fits well into mixed monitors projectors setups. The Monoprice cable wins when the job is a clean, direct link. It is designed for one HDMI source going to one display and supports 4K@60Hz HDR video. The right choice depends on whether your video needs to fan out to multiple screens or travel to one.
Product notes
onn. 4-Port High Speed 4K HDMI Splitter For HDTVs Monitors and Projectors - NEW
This splitter is the distribution hub in the comparison. It accepts one HDMI source and duplicates it to four outputs, so you can send the same 4K picture to a row of monitors, a projector, and an HDTV at the same time. It is new and compatible with universal brands, making it a flexible pick for mixed equipment. The practical limit is that it is a 1:4 splitter, not a matrix or switcher: every screen receives the same signal, and it does not route different sources to different displays. You also need to pair its outputs with HDMI cables to reach each screen, so the splitter is not a standalone all-in-one wiring solution.
Monoprice 4K High Speed HDMI Cable 15m Black PS4 PS3 UHD TV Monitors Projectors
The Monoprice cable is the point-to-point performer here. It is one 4K High Speed HDMI cable in black, designed to connect a source such as a PS4, PS3, or UHD TV to a monitor, projector, or TV. It is an active optical cable for 4K@60Hz HDR video, and the title specifies a 15-meter length, which suits setups where the source and display are far apart. The limit is that it does not split signals: one source, one display. If you plan to mirror a signal to multiple projectors, you need a separate splitter or more than one cable, so match the cable to the job it is actually built for.
Final choice by use case
Choose the onn. 4-Port High Speed 4K HDMI Splitter if your monitors projectors setup centers on showing one 4K source on multiple screens. Its four-way duplication path makes it the better fit for multi-display mirroring. Choose the Monoprice 4K High Speed HDMI Cable if you need one dedicated link between a 4K source and a single monitor or projector. It covers a direct point-to-point connection rather than multi-display distribution. Decide based on whether your bottleneck is too many screens or too much distance.
