T470 and two 4k external monitors via Thunderbolt

Q: T470 and two 4k external monitors via Thunderbolt

I tried to ask on Reddit but it looks like nobody knows the answer. trying it here where could I find a confirmation that the T470 with onboard HD 620 graphics can drive two 4K Dell P2415Q at 60Hz monitors when connected via Thunderbolt? PSREFs just say it can support up to 3 displays (which is cool, but at what resolution and what will be the refresh rate) and max resolution supported is 4K at 60Hz (again, great, but how many of them?)I was planning to use either the Startech's Thunderbolt 3 to Dual DisplayPort Adapter or Dell TB16 dock to connect the monitors, as Lenovo is not providing ways to connect two 4K monitors over the DisplayPortIdeally, I'd love to have a dock which can connect both monitors but as I understand current generation of mechanical docks does not allow to use two 4k monitors, I guess it has something to do with bandwidth of chips used for DP ports in the docks.

Hi there,I've got a new T470 and Ultra Dock and try to connect my 2 external monitors via DisplayPort but nothing happens.I tried to update the firmware of the Ultra Dock but it won't work because I got the following error message in den update.log: "Error description: Can't connect to Synaptics VMMxxxx DP hub IC"The 2 monitors were still connected to the Ultra Dock. So I connected one of those monitors vie HDMI and installed the Firmware again. Now I got the current version 2.33.000 installed. But as soon as I remove the HDMI cable nothing happens again. What else can I do? Do I have an issue with my Ultra Dock?

Hello, I'm trying to connect two external monitors (1920x1200) to my X1 Carbon 6th and only one of them actually works. The other one is displayed as a small square in Windows display settings. When I checked "Advanced display settings", I see all display adapters (3 total), but one of them shows up as "Display 3 isn't active.". I'm using a Thunderbolt 3 to dual displayport adapter (this one). Can anyone help me with this issue? Thanks!

After the time spent with Dell Support doing diagnostics and updating video drivers to those official Dell drivers on the support page, my new XPS 15 9550 with 4K touch display continues to struggle when using external monitors. I have two (2) Dell U2515H monitors.
I have updated ALL of the drivers and BIOS to the very latest files available on the Dell support page, including the newest Thunderbolt 3 driver.
When the laptop is NOT connected to any external monitors, I am NOT experiencing any trouble.
When the laptop is connected to ONE external monitor via the onboard HDMI port, I am NOT experiencing any trouble.
Trouble begins with the addition of ANY external monitor via the USB-C/Thunderbolt 3 port.
I have experimented with the following three adapters, all producing the same result:

Dell USB-C to HDMI (2.0), part number 047KD7
Dell USB-C Port DA200, part number 5KMR3 REVA00
Cable Matters USB-C to DisplayPort
First, regardless of which adapter. my laptop ramps up the fan for as long as the adapter is present.

Second, although the monitor works with any of the adapters at the proper resolution, all of the screens will go black about every 10-20 minutes and the displays will seem to resize and reset. In this process, about half of the time, the windows open on the monitor connected to the USB-C/Thunderbolt 3 port will either minimize or relocate to the primary display (the laptop screen). However, the laptop itself doesn't freeze. I tried running a YouTube video t... Read more

A:Trouble with XPS 15 9550, USB-C/Thunderbolt 3, and external monitors

This is apparently a problem with the Thunderbolt 3 driver/firmware and/or the Intel 530 graphics drivers. I see very similar issues using Dells new TB15 Thunderbolt 3 Dock. Normally when I'm in my home office I use my 9550 with the lid closed using an external monitor connected to the HDMI port. All works perfectly. When I try to use the Dell Thunderbolt 3 Dock and connect my external display to its HDMI port it is unstable. Sometimes the external screen goes blank for a few seconds. When the system wakes up from sleep or I reboot it it does not come up on the external display but I have to open the laptop and switch back to the external monitor. Basically it is unusable. Still waiting for Dell to fix the issues.

Hello,      I have been using a Lenovo T480 with a thunderbolt 3 graphics dock that includes a graphics card. The setup had been working great for about three months until all of a sudden my two external monitors shut off in the middle of some work, and the laptop display turn on. During this time no drivers were being updated and I was using excel. Currently typing of my keyboard and using my mouse hooked up to the dock, so the pass-through for USB ports on it is still working. I also check all the cables but they all seem good and the graphics dock is displaying a green light. I hopped on the Lenovo support page, for the T480 and downloaded all the auto drivers, then proceeded to download: Lenovo Thunderbolt 3 Graphic Dockhttps://support.lenovo.com/us/en/downloads/ds500314 Intel HD Graphics Driver for Windows 10 (Version 1703)https://support.lenovo.com/us/en/downloads/ds502213 Critical Intel Thunderbolt Software and Firmware Updates - ThinkPadhttps://pcsupport.lenovo.com/sk/en/solutions/ht508988 Any ideas? Thanks,Eric

Both the operating system and all Lenovo updates have been applied. Attached to thos is a Plugable-brand USB3 dual HDMI docking station that's been driving a pair of Dell SE2417HG(HDMI2) screens. Or did, until I did the Integrated Firmware of Thunderbolt Function 1.0.12.0-N1QTF16W update, at which point it now only drives a single screen. Windows sees both displays but now can't use one.

Today, I noticed that my USB-C docking station was no longer passing video from my T470 to my monitor. The monitor's HDMI cable is plugged into a docking station that is connected to my T470 via USB-C. It's been working fine for more than a year. All other connectivity via the docking station works (e.g., keyboard, mouse, ethernet, power). The docking station, including video, works just fine with another (non-Lenovo) PC. My first thought was to check Lenovo Vantage or the support website for Thunderbolt software and/or firmware updates. The most recent software is several months old and already installed on my machine. I can see that there's a relatively recent firmware update on the website, but it's specifically for Windows 10 1809 or older. I am running 1903. When trying to install that firmware update, I receive an error message (can't find suitable bin file). Vantage does not find any updates for me to install. I did see this post, which mentions HDMI output not working as a symptom (among others). However, it recommends the Thunderbolt software that has been installed for several months as well as the firmware that I cannot install. I have two questions:Is anyone else having problems with HDMI output via their T470 USB-C/Thunderbolt port?Is there any news on when there will be a new T470 Thunderbolt firmware update for Windows 10 versions newer than 1809?

Hi, I have a T470 laptop with the USB-C charger. I'd like to connect a DisplayPort LCD screen to use as a second display while simultaneously being connected to A/C power and charging my batteries. I am having a bit of trouble figuring out what my options are. 1. I could buy a Thunderbolt 3 hub/dock with a DisplayPort connector on it. I would then connect the charger to one of the USB-C ports on the hub/dock, and the screen to the DP connector. From what I can see, these hubs are fairly expensive, so given that I currently don't need to connect any other TB3 devices I'd like to avoid it if possible.2. I could buy a USB-C - DP adapter or cable, but I have not seen anything with some kind of pass-through function which would allow me to connect my charger. I thought daisy chaining was something TB3 can do, but unfortunately the charger does not have the ability to do this (I know a DP connection has to be at the end of the chain).3. The T470 has a slim tip charge port, in addition to the ability to be charged via the TB3 port. Perhaps a USB-C - slim tip adapter exists which would allow me to connect my charger to the slim tip port, and not worry about the lack of daisy chaining in point 2. I've found a different adapter (wrong interface and wrong direction), but nothing that can do this. Thanks for any info/advice!

My office just upgrated to the the Zbooks with thunderbolt docking stations. Most of us have 2 monitors. Those of us with LG monitors can not connect both monitors using the Display ports or it locks up the docking station or notebook. If we connect one in the display port and one with VGA it will work. But the one in the display port drops from 1680X1050 to 1600 X 900. The one connected with VGA will have 1680 X 1050. Notebook will not let us put the display port any higher than 1600 X 900. This are the same monitors. On the old notebooks we had this was not a problem. Both were being run at 1680 X 1050. Please someone tell me what I need to do to get this to work. On the filp side some people have Bell monitors and this is not a problem with them. It is only with the LG monitors that we have this problem. The LGs are 2 years old.  The dells are over 5 years old.

No Security: Allow Thunderbolt devices to be connected automatically.
User Authorization: Allow Thunderbolt devices to be connected after user authorization.
Secure Connect: Allow Thunderbolt devices to be connected with a saved key that has been approved by the user.
Display Port and USB: Allow only DisplayPort-compatible devices and USB devices to be connected.

I have a P52 and a Lenovo Thunderbolt 3 Dock Workstation Gen2 On the dock I have 2 Dell U2415 connected via a DisplayPort cable and a microsoft wired keyboard. When I lock the computer, the monitors turn off after a few seconds. Usually any key press or mouse move wakes up the monitors so I can login to Windows 10. The problem I have is that since the last firmware update 3.1.64, the screens don't always wake up when I press a key. A workaround to nudge the screens to wake up is to switch off one monitor, then switch it back on when the other screen wakes up. Another workaround is to press the dock button which puts the computer to sleep, then wake it up after a few seconds. Clearly both workarounds are not ideal and I would like this problem fixed. Note that I had the same problem when I bought the dock with the original dock firmware 3.1.53 and the problem was solved when I upgraded to version 3.1.61.  I have tried installing firmware 3.1.61 as I had the files around but the installer will not let me downgrade. Is there a way to force a downgrade to version 3.1.61 or is there another way to fix this problem? Thanks

Not able to get two monitors (Samsung S27E450) plugged into a ThinkPad Thunderbolt 3 docking unit to work with my X1 Yoga (Gen 2).   Montiors connected to docking via DisplayPort cables.   Windows 10 shows the monitors showing up as "Generic PnP" so something is being recognized.  Tried deleting the device in Device Manager, reboot.  Not finding the drivers on the Samsung site.   Any help appreciated.

I have a Thinkpad T470 and a Thinkpad USB 3.0 Pro dock. I have Win 7 on it with Bitlocker enabled. What I would like to do is setup the laptop to boot to one of the external displays so I get the bitlocker screen on my main monitors. I went into the bios and it seems to have an option to do that but that doesn't seem to work. Is there something I can do to make that work?

Have one 4K 6Hz monitor connected to my T25 which is the same mashine as the T470. The mashine just gets so slow, and GPU/CPU running hot and slow with fan on often just from browsing and youtube. When using the 1080p screen in the laptop with same tasks no problems. Should it not be able to handle 4K screen? If not what resolution is the sweetspot for external display? Have connected the monitor with display port from my ultra dock.
