Turned a single displayport connector on the back of the PC into three separate monitors. In my case two of the monitors are Full HD and a third is only 1280x720, and it all works fine. Windows immediately recognises three separate displays just as if the PC had three outputs directly on the back. I use a cheap Displayport->HDMI adaptor on one of the outputs and that works fine too. Worth mentioning that the device needs power, and it comes with a multi-country adaptor in the box for that, but you will need a spare mains socket near the PC for it - without the power none of the extra outputs work. Review: Phenomenal device - One of the first in-depth comments I've written about anything on desertcart because I'm that impressed. I've recently completed a house build and have been WFH using my 13" laptop in various improvised settings like the wife's make-up table, our dining table and couch. Finally, with an office to call my own I go on a spending spree and buy some LG 27" 1440p 144Hz Ultragear monitors... Both monitors have 2 * HDMI and DP. It wasn't my intention to use 144Hz for work - I knew that was a none-starter. But I wanted 60Hz minimum and I'd have 144Hz for my personal rig. Anyway, the fun then begins. I have an HP Elitebook 840 G3. It's getting on a bit, only has one DP, a VGA which I never use, and the ability to use DisplayLink using an appropriate dock on the USB A SS to drive 2 * 1080p displays - which I did when I was based in the office, however the market is littered with docks which range from random Chinese poor quality 30Hz 1440p if you're lucky all the way through to £200 powered docks which *may or may not do 60Hz 1440p*. Minefield widens - the USB C is standard, not Thunderbolt so that rules out all those docks dependent on it. Likewise, I didn't really want to drop a couple of hundred on an aging work laptop. The 840 G3 manual mentions, very briefly, and not with any sort of confidence that it supports MST over DP - the ability to drive two displays using DP 1.2. Some monitors include a second DP to act as a 'daisy-chain' over to the next monitor, however the ones I bought don't so I couldn't attempt it. There were question marks about the laptop's graphics ability to drive 2 * 1440p displays at 60Hz anyway. I was about to give up - I didn't fancy starting buying 10 different products on the off-chance one worked, so was kind of resigned to one monitor and laptop by the side. It'd be a country mile better than what I had. But, I stumbled across this. Gave it a shot. Glad I did. Out of the box, with no drivers to worry about (if like me your work laptop is limited installing stuff), instantly driving 2 * 1440p 60Hz displays. So there you go, even on relatively old hardware, if your graphics setup has a DP 1.2, you'll more than likely be able to drive 2 * 1440p @ 60Hz using this. And with no separate power source to worry about, even better. P.S. I have a daughter who insists on her coloured drawings as backgrounds. My work laptop may be neutered, but at least they let me choose a custom desktop background! ## Features - MULTI MONITOR ADAPTER FOR WINDOWS: Triple DisplayPort MST hub drives up to 3x DisplayPort monitors in extended or duplicate mode using a DP port on Windows desktop PCs or laptops | Not compatible with macOS - DISPLAY RESOLUTION: Triple monitor DP MST hub supports resolutions up to 2x 4K 30Hz + 1x 1080p 60Hz on three monitors or three ultrawide displays up to 2560x1080 60Hz - COMPATIBILITY: 3-Port DisplayPort MST video splitter works with laptops, computers or desktop graphics cards |Requires host system with DP 1.2/HBR2/MST or later from HP, Dell & Lenovo and AMD, Nvidia & Intel video cards - INCREASE PRODUCTIVITY: Increase productivity by extending your desktop at your workstation in the office/home office | MST technology uses your GPU/video card performance to deliver uncompressed video and use minimal system resources - EASY TO USE: Triple monitor adapter natively supports 3x DP monitors; Works w/Windows only and provides an easy driverless setup | Latching DisplayPort connector ensures a reliable connection and prevents accidental disconnection - CONVENIENCE: MST (multi-stream transport) hub is equipped with a built-in 5.5" (14cm) cable for video (DisplayPort) and an AC power adapter | Supports LPCM digital audio - GPU CAPABILITIES: Please verify maximum number of displays supported by your GPU; Some GPU chips (such as Intel HD Graphics) are only capable of supporting a maximum of three displays (laptop screen may be disabled when connected to three monitors) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00JLRBB8I | | Best Sellers Rank | 39,278 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 7,876 in Cables (Computers & Accessories) | | Brand | StarTech | | Brand Name | StarTech | | Colour | Black | | Compatible Devices | Monitor, Personal Computer | | Compatible devices | Monitor, Personal Computer | | Connector Type | DisplayPort | | Connector type | DisplayPort | | Customer Reviews | 4.0 out of 5 stars 1,233 Reviews | | External Testing Certification | RoHS, CE, FCC | | Global Trade Identification Number | 00065030851886 | | Item Dimensions | 38.6 x 7.9 x 2 centimetres | | Item Type Name | Signal Splitter | | Item Weight | 100 g | | Item dimensions L x W x H | 38.6 x 7.9 x 2 centimetres | | Manufacturer | StarTech.com | | Manufacturer Part Number | MSTDP123DP | | Model Number | MSTDP123DP | | Number of Items | 1 | | Number of Ports | 3 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Product Finish Type | Matte | | Smart Home Compatibility | Not Smart Home Compatible | | Specific Uses For Product | PC, Monitor | | Specific uses for product | PC, Monitor | | UPC | 065030851886 | | Unit Count | 1.00 count | | Warranty Type | Limited | ## Product Details - **Compatible devices:** Monitor, Personal Computer - **Specific uses for product:** PC, Monitor - **Connector type:** DisplayPort - **Colour:** Black - **Item dimensions L x W x H:** 38.6 x 7.9 x 2 centimetres ## Images ![StarTech.com 3-Port Multi Monitor Adapter - DisplayPort 1.2 MST Hub - Dual 4K 30Hz & 1x 1080p - Video Splitter for Extended Desktop Mode on Windows PCs Only - DP to 3x DP Monitors (MSTDP123DP) - Image 1](https://m.media-amazon.com/images/I/61YJE5ZIhGL.jpg) ![StarTech.com 3-Port Multi Monitor Adapter - DisplayPort 1.2 MST Hub - Dual 4K 30Hz & 1x 1080p - Video Splitter for Extended Desktop Mode on Windows PCs Only - DP to 3x DP Monitors (MSTDP123DP) - Image 2](https://m.media-amazon.com/images/I/613CLNFkVIL.jpg) ![StarTech.com 3-Port Multi Monitor Adapter - DisplayPort 1.2 MST Hub - Dual 4K 30Hz & 1x 1080p - Video Splitter for Extended Desktop Mode on Windows PCs Only - DP to 3x DP Monitors (MSTDP123DP) - Image 3](https://m.media-amazon.com/images/I/61llMQruznL.jpg) ![StarTech.com 3-Port Multi Monitor Adapter - DisplayPort 1.2 MST Hub - Dual 4K 30Hz & 1x 1080p - Video Splitter for Extended Desktop Mode on Windows PCs Only - DP to 3x DP Monitors (MSTDP123DP) - Image 4](https://m.media-amazon.com/images/I/81IjMlGmmoL.jpg) ![StarTech.com 3-Port Multi Monitor Adapter - DisplayPort 1.2 MST Hub - Dual 4K 30Hz & 1x 1080p - Video Splitter for Extended Desktop Mode on Windows PCs Only - DP to 3x DP Monitors (MSTDP123DP) - Image 5](https://m.media-amazon.com/images/I/71Iy6hWjs+L.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Does it work in reverse, to connect multiple computers to one monitor, one at a time, rather than having to switch the cable from PC to PC?** A: No. You'd want a KVM switch for that. **Q: Is this MST usable with displayPort output and hdmi input? Will I benefit of extended desktop?** A: No it will not. Some more expensive Display port monitors have the electronics to daisy chain more monitors from one port. If your monitors do not have this facility then this is when you need this unit.It allows the connection of three Display Port monitors to one Display Port Graphics card output.HDMI is really DVI with Audio and, each port only supports one monitor. DP is completely different in operation and, can transmit other information as well as display.Hope this clears it up for you. **Q: I want to be able to use two monitors independently, ie. move the picture from one to another, will this work? also, any reported issues with sli?** A: It is a good question, which I wrestled with last year, and it is hard to get good information from manufacturers. By experiment (and having to return a couple of products) I found that the answer - at least for a Mac is, sadly, NO. I gather the story may be different for a PC, but I have not tried one. On the Mac, these multi-port products only give you mirroring. To implement desktop expansion as you want (which was my requirement as well) you have to buy a SEPARATE adapter for EACH SCREEN, then connect them (as many as you like) using a (good quality) USB hub. There are videos on YouTube about how to do this. As this is a bit expensive you should remember that many Apple computers - a Mini Mac for example - already give you two ports: one mini port and one HDMI. I my case, I just bought adapters for these for the first two screens and I use the StarTech adapter for the third screen. The third screen is a beat slower than the others and the colour is not a perfect match, but if you are not running videos this is not a problem. I hope that helps. Good luck! **Q: Can this be used for gaming consistently on 3 monitors at 75Hz plus?** A: We've used it for 3 HD projectors running a graphics intensive programme with no problems. ## Customer Reviews ### ⭐⭐⭐⭐⭐ instantly drive three monitors from one displayport socket *by I***N on 16 December 2017* Brilliant device.

I picked this one as I'd read mixed reviews on all the others. So far my experience is that it's very good but with 1 annoyingly flaw. Occasionally (maybe once every 2 weeks) it stops recognising the 3rd monitor and the only fix is to turn everything off from the mains and then turn it back on. I've tried different sockets and even at a friends house but the problem persists. Googling the problem indicated that this is one of those problems that no one reliably solved. ## Frequently Bought Together - StarTech.com 3-Port DisplayPort 1.2 Splitter, DisplayPort to 3x DP Multi-Monitor Adapter, Dual 4K 30Hz and 1080p 60Hz Computer MST Hub, Windows Only (MSTDP123DP) - BENFEI 8K DisplayPort to DisplayPort 6 Feet Cable [VESA Certified], DP to DP Male to Male Cable Gold-Plated Cord, Supports 8K@60Hz, 4K@144Hz 120Hz, 2K@240Hz Compatible for Lenovo, Dell, HP, ASUS More - BENFEI 4K DisplayPort to HDMI Adapter, Uni-Directional DP 1.2 Computer to HDMI 1.4 Screen Gold-Plated DP Display Port to HDMI Adapter (Male to Female) Compatible with Lenovo Dell HP and Other Passive --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/50844662-startech-com-3-port-multi-monitor-adapter-displayport-1-2](https://www.desertcart.jp/products/50844662-startech-com-3-port-multi-monitor-adapter-displayport-1-2) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-21*
