ThisMST hubsolves both of these problems by letting you connect three additional displays to your computer, which makes multitasking much easier.Connect to any displayWith the MST hub, you can use DisplayPort video adapters and cable adapters that enable you to connect HDMI, VGA or DVI displays. This ensures your MST hub will be compatible with virtually any television, monitor or projector. This MST hub is VESA and DisplayPort certified to support DP 1.2 enabled systems, for seamless integration with your existing video equipment.Configure your displays for any environmentUsing the MST hub, you can extend your desktop onto additional monitors and stream independent content to each display giving you the freedom to multitask and increase your productivity. You can also mirror the same image onto multiple displaysfor remote viewing applications such as digital signage.Enjoy amazing video quality, without draining system resourcesMST technology uses your existing video card to minimize the use of system resources while delivering Ultra HD 4K resolutions. This unprecedented performance makes MST perfect for high-resolution applications such as graphic design, gaming and medical imaging.Note: When using a DisplayPort 1.1 video card the MSTDP123DP will act as splitter, automatically mirroring your video source across all displays. Resolution limitations apply.The MSTDP123DP supports plug-and-play installation for a hassle-free setup, and is backed by a StarTech.com 3-year warranty and free lifetime technical support.Note: MST shares 21.6Gbps across all attached displays. Higher resolutions can restrict the available bandwidth with the remaining ports, please see our guideline below for determining an ideal resolution for your setup.Certain graphics adapters have limited MST support and will only output to three displays in total. If more than three monitors are attached the fourth will be disabled.Average Resolution Bandwidth Allocation1920x1080 (High-definition 1080p) @60hz - 22% 1920x1200 @60hz - 30% 2560x1440 @60hz - 35% 2560x1600 @60hz - 38% 3840 x 2160 (Ultra HD 4K) @30hz - 38%Note: Exceeding 100% will reduce functionality.Examples of Supported Resolution Configurations Screen 1 Resolution Screen 2 Resolution Screen 3 Resolution Total % of Bandwidth 1920x1200 @60hz (30%) 1920x1200 @60hz (30%) 1920x1200 @60hz (30%) 90% 2560x1440 @60hz (35%) 2560x1440 @60hz (35%) 1920x1200 @60hz (30%) 100% 2560x1600 @60hz (38%) 2560x1600 @60hz (38%) 1920x1080 @60hz (22%) 98% 3840x2160 @30hz (38%) 2560x1600 @60hz (38%) 1920x1080 @60hz (22%) 98% 3840x2160 @30hz (38%) 3840x2160 @30hz (38%) 1920x1080 @60hz (22%) 98%Examples of Unsupported Resolution Configurations Screen 1 Resolution Screen 2 Resolution Screen 3 Resolution Total % of Bandwidth 2560x1600 @60hz (38%) 2560x1600 @60hz (38%) 1920x1200 @60hz (30%) 106% 3840x2160 @30hz (38%) 2560x1600 @60hz (38%) 1920x1200 @60hz (30%) 106% 3840x2160 @30hz (38%) 2560x1600 @60hz (38%) 2560x1440 @60hz (35%) 111% 3840x2160 @30hz (38%) 3840x2160 @30hz (38%) 3840x2160 @30hz (38%) 114%More from the Manufacturer Legal Disclaimer Product is sourced and shipped from the European Economic Area (EEA).

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. 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. ### ⭐⭐⭐⭐⭐ Works as advertised *by T***D on 9 May 2017* Worked straight out of the box with no issues with my HP Book G2 ultrabook supporting 2 26" Asus full HD monitors - resolution is great and I don't have any screen problems. I only wanted two monitors when I purchased it but now I have the capability I'm considering adding another.Used daily in my home office for 2D autocad, office, email and occasional 3D modelling.I'm powering it from the supplied power brick and not USB as some users seem to be doing ### ⭐ Good service, problems with product design *by G***T on 16 February 2016* Firstly, I have just been on an online webchat with David from customer service and he was superb. Unfortunately couldn't resolve the issues but tried everything. Noteworthy good customer service.I have had this a week now and had a few issues I would like to share to help others.1. When my PC resumes from sleep, all the monitors do not always fire up. They are all manually set to the correct input, not auto. The workaround is to press the scan button on the hub, then everything works fine within a second or two. The issue is the location of the hub behind my desktop under the table as many other peoples will be. Not convenient. If you are happy doing this then I found the hub worked fine with my three 1080p monitors.2. So I tried a 3rd party 2m DP male-female extension lead between the PC and the hub, so that I could have the hub on the desk with the scan button accessible. In no configuration does this work; 3 monitors, 2 monitors or 1 monitor. Since it doesn't work with one I don't think it is an attenuation/bandwidth issue with the extension lead. Using the extension lead between the monitor and the hub, however, works fine!TLDR; You have to press the scan button every time the PC wakes from sleep and you can't use a DP extension cable between the PC and the hub. ## 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.pl/products/50844662-startech-com-3-port-displayport-1-2-splitter-displayport-to](https://www.desertcart.pl/products/50844662-startech-com-3-port-displayport-1-2-splitter-displayport-to) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-07*
