Review on 💻 Accell mDP-2DP Multi Monitor Splitter - Mini DisplayPort 1.2 MST Hub - 1 Mini DP to 2 DP Outputs by Rod Evans

This product works and does what it promises, but with a few limitations. It's pretty finicky and an absolute nightmare to set up and get working properly. If you're using this to run non-Displayport monitors, you're in for a long day of setup and setup. It's not just plug and play, it's plug and pray. I use it on nVidia Quadro K2200 to support 4 monitors. If the two devices you're connecting to it are native Displayport monitors, it will most likely work without too much trouble. If it's something else, like HDMI or DVI, only one of them will likely work if both have the same connection type. My current working setup consists of two identical RCA HDMI TVs and two Acer V246HL monitors. I have an Acer monitor connected directly to the Quadro card's DVI connector, an RCA TV directly to the card's Displayport via an HDMI to Displayport cable, and this Accel MST hub to the Displayport connector on another Graphics card connected. I connected an RCA TV to the MST hub using an HDMI to Displayport cable and an Accell active Displayport to DVI adapter that powers another Acer monitor. This is the ONLY configuration of these four devices that will work. I'm an experienced IT professional and I've tried every possible way to connect these four devices with every imaginable passive and active adapter. This is the only way to get 1920x1080 resolution on 4 separate monitors. Also, this hub does strange things with EDID information. The nVidia control panel somehow knows there are four monitors, but not quite as if four were plugged directly into the graphics card. If EDID is important to you in your setup, this device may not be for you. I had to export the EDID information of the RCA TVs connected directly to the card to a text file and tell the nVidia control panels to read it from there, as using this MST hub caused the card to somehow not recognize the others . RCA TV on reboot, which requires the display to be physically disconnected and reconnected on each reboot. The order in which I connected the elements to the graphics card and MST hub made a big difference in getting everything recognized correctly. Also, two HDMI TVs will not fully work on this MST hub and two DVI monitors (with an active or passive adapter or one each) on this MST hub will not work. It should also be noted that when HDMI audio is muted (!) in Windows playback devices, this MST hub may appear to put zero audio on the HDMI output, which is a big problem for me, because it leads to the assumption that it's getting sound when it's clear, it isn't and it won't mix with the analog 3.5mm signal. The problem with all this newfangled Displayport stuff is that all of these caveats and technicalities aren't properly documented anywhere, and unfortunately an unsuspecting user like you should look to reviews like this for help because you can't just read (Friendly ) manual because there is none. After lots of disconnects and reconnects, reboots and more, I finally have a working stable configuration, but for most users it's probably better if you buy a graphics card if you use it to go from 3 monitors to 4 four different monitors. . ports on it.
