10 reviews for HP Thunderbolt Dock 120W G2 (2UK37AAABA) Docking Station Port Replicator

    Does not work with Macbook & Dual MonitorsThis is probably superb for a Windows PC, but the description is deceitful. It claims to work with Dual monitors for a Mac, but in reality, it is just a mirrored (the same) image on each monitor. It’s hard to comprehend anyone would want mirrored monitors for their docking station in the office. I returned because of this reasion and indeed was charged a 15% restocking fee on top of the disappointment.

    Buggy – but with a TB3 cable does dual-display + 100WPros:Works over ThunderBolt3 with HP Spectre 15″ & MacBook Pro 2016+. Dual display worked with U3011 2K@60Hz DP-DP, LG 27GL850-B 2K USBC-DP, and VGA, using left-sided DisplayPort is plugged in, and rear-right-side USBC port.Cons:- Buggy: HP’s dock firmware upgrade causes BSOD on Win10 1909. HP Support is unreachable.- Buggy: I tried 7 cables compatible on the CalDigit TS3+, 5 failed on the G2; full DP cable in left slot + right USBC worked. TB3 port failed to daisy-chain to the TS3+ TB3 dock and fails with most cables too.- Bad design: Top panel (1/6th of the unit!) is a power button that cannot be disabled, you will shut down often, accidentally. The dock has its own fan and low CPU activity activates the laptop fan even when not charging.- Bad on MacOS: TS3+ @ 85W works immediately, G2 @ 100W only has no ethernet, no audio, no dual-display on Catalina; yet both work in Bootcamp Win 10 1809 on MBP 2016+.- Vendor lockin: TS3+ is more reliable and versatile in all but one case: HP 15″ charges on HP G2, but HP’s Windows Notifications ask for power cable with TS3+ under moderate CPU load.Conclusion:For an HP 15″, or if for $50 you’re willing to live with bugs, buy the G2.For anything else get a CalDigit TS3+ (refurbished, on holidays for 15% less).

    Used with HP Spectre x360 15tSo far I’ve tried this product only briefly. I have been able power the laptop while driving two 1440p displays. My sense is that the powering might be a little weak, but it is enough to add charge to the laptop battery while playing a full screen 720p YouTube video on the native 4k display and doing not much on the two external displays.My main wish at this point is that the price would not be so high. Otherwise I’d buy more of these.I intend to post more here once I’ve tried these out longer.

    Does NOT work with dual monitors on HP laptopI purchased this dock thinking that it would work with my dual monitor setup. It did not. I spent some time reading the description and reviews on this item before making this purchase. I don’t know what the other reviewer did to get it to work with dual monitors but the product that I was sent definitely did not function as expected. Overall, I am very disappointed with this item and will be replacing it immediately.

    Doesn’t save you from connecting important cablesI have a Zbook G5 15. It draws more than 100 Watts power and that exceeds USB-C standards. So that would need an additional (and obviously expensive) cable to be connected with the Zbook power input. Dock does not manage HDMI, so another cable connected directly to the Laptop. Ethernet is much slower using the dock, so another cable directly connected to the Laptop……Are you kidding me, a docking station just to connect the mouse ?

    Infuriatingly complicatedI have dealt with many Thunderbolt 3 docking stations (Tier 2 EndPoint Support) and this is one of the worst! I have all of the drivers on my HP Spectre laptop (BIOS, Graphics, Chipset, Thunderbolt Control, etc.). I have updated the firmware for the docking station as well. I have a 27″ HP monitor that connects through a DisplayPort cable – never gets a signal. I would NOT RECOMMEND this to anyone.

    Maybe it will work someday, but not for Razer/Apple laptopsBeautiful design, terrible product. Connecting this to a razer blade stealth never worked, and I tried a 15 Macbook Retina with the same problems, even after installing all the drivers. If this product worked then it would be an amazing product, but for now I cant recommend it due to the lack of compatibility.

    Good Dock – But Was I Sold a “Return”?This dock works as advertised (thus far). No issues there. But I seem to have been sold a previously used & returned unit.My company has purchased a dozen of these docks directly from HP. I decided to personally buy one through Amazon to set up a remote workstation at home. When my shipment arrived it was in the same HP packaging as the docks my company purchased from HP. But when I opened the box I discovered the dock & power supply were not wrapped in plastic and there was no installation guide or other documentation included. The cords were loosely wadded in the box — not neatly wrapped with twist-ties as they always are with a new purchase.I set-up the dock and it works, which is the bottom line I suppose. But disappointing that an Amazon vendor is shipping previously returned products and with sloppy packaging. I certainly hope I won’t have issues with this dock — in case a previous buyer returned it due to problems.

    Besser als ich aufgrund von Rezensionen erwartet habe!Meine Voraussetzungen und mein Ziel sind: HP Spectre 360 Notebook von Ende 2019 und problemloses Umschalten zwischen diesem (Firmen)Notebook und meinem Standrechner in meinem Homeoffice.Ich habe zuerst Abstand genommen von dieser Docking Station, da einige geschrieben haben, dass darin ein lauter Lüfter laufen würde und dass es Probleme gäbe mehr als einen Monitor anzuschließen. Also habe ich zuerst das G5 Dock von HP gekauft um dann festzustellen, dass man damit keinen 4k Monitor mit 60 Hz betreiben kann. Danach habe ich noch eines von Dell und eines von Wavlink getestet. Mit keinem ist es mir gelungen mein Setup zufriedenstellend zu betreiben.Mit dem G2 Dock (120 Watt) funktioniert das Wichtigste und meine Erwartungen waren eh schon sehr zurückhaltend.1. Es gibt gar keinen lauten Lüfter! Ich vermute, dass dies nur die 230 Watt Version betrifft und dass die Rezensionen einfach vermischt wurden unter den unterschiedlichen Versionen was leider immer wieder der Fall ist bei diversen Produkten. Aber das ist wie gesagt nur eine Vermutung. Ich habe jedenfalls noch absolut kein Geräusch vernommen von dem Dock.2. Das wichtigste war für mich, dass mein 4k Monitor mit 60Hz einwandfrei und ohne irgendwelche Verzögerungen oder Ruckler funktioniert und das tut er! Angeschlossen habe ich ihn mit einem USB-C Thunderbolt auf HDMI 2.0 Kabel und am Display Port Eingang des Monitors ist mein Standrechner angeschlossen.3. Weiters ist ein Full-HD Monitor via Display Port auf HDMI Adapter angeschlossen und auch das funktioniert einwandfrei. Das heißt ich habe den 4k Laptop Monitor, meinen 4k Hauptbildschirm und einen Full HD Monitor problemlos in Betrieb und damit kann ich ganz gut arbeiten.4. Beim Versuch einen weiteren Monitor via VGA anzuschließen, verlor ich den Ausgang zum 4k Hauptbildschirm. Also alle Ausgänge kann man offensichtlich nicht zugleich verwenden. Ob es funktioniert hätte, wenn ich den zweiten Display Port Ausgang verwendet hätte, konnte ich mangels Adapter nicht testen.EDIT: Man kann sämtliche Kombinationen der Ausgänge nutzen, allerdings kann die Grafikkarte im Notebook nicht mehr als drei Displays ansteuern. Da heißt das interne Display plus zwei externe Displays, oder nur drei externe Displays (nicht ausprobiert).5. Alle USB-Geräte funktionieren einwandfrei und ohne Aussetzer (leider nicht selbstverständlich wie ich bei anderen Docks feststellen musste). Das heißt ich kann mein externes Audio-Interface, meine mechanische, beleuchtete Tastatur, usw. problemlos mittels USB-Switch mit Standrechner und Dock (Notebook) verbinden. Das Umschalten am Switch funktioniert einwandfrei.6. Das Laden des Notebooks funktioniert ebenso einwandfrei.Fazit: Ich habe in meinem kleinen Homeoffice, welches zugleich so eine Art Studio ist, ca. 60-70 Kabel verlegt und bin froh nun endlich eine Lösung gefunden zu haben um mein Firmen-Notebook mit nur einem Kabel an die wichtigsten Geräte anzuschließen und zugleich laden zu können. Insofern ist es verglichen mit anderen Geräten nicht nur das einzige, dass alle meine Erwartungen erfüllt hat, sondern auch preislich noch einigermaßen im Rahmen. Einen Stern ziehe ich ab, weil es wie bei den meisten Artikeln leider schwierig war im Voraus anhand exakter Spezifikationen heraus zu finden was das Teil nun wirklich kann und ob es irgendwelche Geräusche macht oder nicht.

    Does not wake external screen after the laptop has been sleepingI’m using the latest gen HP Spectre X360, I was already unimpressed with HP docks after buying the USB-C dock G5 and having to return it as it would not work at all with my USB-C monitor. I then purchased this more expensive Thunderbolt Dock G2. I was happy at first as my USB-C monitor worked out of the box. That happiness lasted until I went and made a coffee, then came back to discover once my laptop screen goes to sleep the external monitor will not wake up again unless I disconnect and re-connect the entire dock!I have read countless solutions to this problem online and the one thing apparent in all of them is that there is no solution! I am not returning the dock as I use my laptop and monitor side by side so I can live with disconnecting and reconnecting every time I step away and will hope that HP come up with a solution soon but I wont hold my breath. Expensive laptop and expensive dock yet the fundamentals don’t work – come on HP!Edited to add that the dock has a built in fan which seems to turn on or speed up randomly even when the laptop is switched off. Since I have this in a bedroom it’s slightly annoying but it’s not loud enough to stop sleep.Edited again as I have changed from a USB-C 4k monitor to a DisplayPort 2k monitor and the issue with the monitor not waking up with the laptop persists, therefore this definitely seems to be a problem with the dock.
