Q: Lenovo Yoga S740-14IIL Thunderbolt HDMI isnt working

Hello to everyone, maybe someone can help me with my problem or has some advice: I bought a new Lenovo Yoga S740-14IIL and wanted to use an external display via the USB Typ C Thunderbolt port, which should be capable off it and is marked by a little Thunderbolt-logo.But nothing is working: There is no signal and it just shows "Billboard USB Device" in the Hardware manager of Windows 10. I used a "Hommie USB C to HDMI Adapter ([email protected])" device to connect. I tried different things:- Using different monitors- Using another OS (Ubuntu) for testing- Installing the automatical Lenovo Updater on WIndows but it hadnt found new Updates Ive read in the forum that other Notebooks have similiar problems with HDMI output via Thunderbolt, but nothing about the Lenovo Yoga S740-14IIL yet. Best regards and thanks for your adviceMSPD

Go to start, type in "Display", and go to the display settings. How many monitors does it show? Try the "detect" button - does it see it then? Is the adapter and wire functional?Press the Windows Button and 'P', and choose duplicate. Does it do anything?Let me know.

Hi, I would like to buy a docking station.I basically did some research and found out that this one should fit best: https://support.lenovo.com/de/de/solutions/pd500265There is no dedicated docking station for the Yoga series, right? What do you think about the Thunderbolt 3 dock Gen 2? Best regards,Reiner

HelloI have purchased Yoga S740-14IIL  and first thing I have found that camera is so norrow vertically. When you sat down on front of it and set the lid to your perfect position camera misses your head. And half of your head is displaying. These are the two different images that show the camera having same lid angle with my yoga and macbook.   This is huge different. Is it same for you guys for all win notebooks or just macbooks have this capability?

Hello,I am a litte bit confused with the available information about the type of the 2 USB-A connectors on left and right side of the chassis of Yoga S740, 14inch. The Lenovo web shop for Germany says its USB 3.1 (Generation 2 = 10 Gbps) (see https://www.lenovo.com/de/de/laptops/yoga/yoga-s-series/Lenovo-Yoga-S740-14IIL/p/81RS0016GE) whereas, the manual says it is USB 3.1 (Generation 1 = 5 Gbps). The logo close to the connectors on my Yoga S740 says "SS" - if I remember correctly Gen 2 should have a "SS+" logo, so probably it is a Gen 1 only.Unfortunately, I don't have any devices with Gen 2 interface, so I cannot validate my assumption. Anyone here has an idea? Thank you,Thomas

I couldn't get the audio output with 5.1 channel audio on that HDMI and Dislay Port. Is there something wrong with my setup or this is a limitation of Thunderbolt 3 Dock to provide multichannel audio. I can use only 2 channel stereo audio only.

All of a sudden, my hdmi and the thunderbolt3 ports stopped working. I've tried multiple fixes: 1) Setting Thunderbolt Assist Mode -> Disabled, Reinstalled drivers, Updated Bios 2) Using the pin trick to reset the battery Issues: Cannot see the Thunderbolt 3 under System Devices. I ran the thunderbolt firmware detect tool and got this error message instead: 0x20B SDK_NO_CONTROLLERS Cannot flash/update the Thunderbolt 3 Firmware. All I get is this error:   And if I go and check About in the Thunderbolt Software:   I am pretty much at my wit's end here. I pretty much use an external monitor and it just stops working.

Hi all, In the past few days my laptop slowly degraded, starting with docking station connectivity not working (but does work with other laptops), then HDMI port not working (HDMI screen and cable works with other laptops), and now system no longer charges. Current status is that all USB-C ports (including charge) and HDMI port and not functioning. Computer doesn't charge when it is off, too.  I've looked at multiple solutions and threads on this website without any real solution. I've already tried - - run Lenovo Vantage a few times to check updates. Did the same on the Lenovo product website (using auto-discovery of serial #), everything is fully updated- Turned on/off Thunderbolt Service (on the Windows 10 control panel) - I turned it on and automatic but it always returns to Manual- Searched in the Device Manager for Thunderbolt (anything) - it's not there- Uninstalled and re-installed Thunderbolt software from the Lenovo website (both controller driver and FW, file names n1nta05w.exe and n1nth08w.exe)- Went to the BIOS/Configuration - enabled and disabled again all Thunderbolt related options - Used Paperclip to do hard reset using the emergency reset button Any ideas what left to be done?  Thanks!

Hello Community-  I recently purchased a Lenovo X1 Carbon along with a Lenovo Thunderbolt 3 and two monitors. I have tested out the monitors individually with another computer, and they work fine.  Currently, I have one monitor connected via VGA to the Thunderbolt dock, and I have 1 monitor connected via HDMI to the Thunderbolt dock, which is connected to my Carbon x1. I only have connectivity with the VGA connected monitor, and do not have connectivity with the HDMI connected monitor, although I hear the system "connection sound" when I plug in the HDMI cord.  What is the issue here?  My goal is to have two monitors connected via Lenovo Thunderbolt 3 docking station to my X1 Carbon laptop. Thank you

Hi,Background on Issue I've had the Thinkpad X1 Yoga 2nd gen (product # 20JDCTO1WW; BIOS version N1NET46W 1.33) since it came out. It's running the latest build (non-targeted channel) of Windows 10 Pro with all Windows updates and all Lenovo System updates installed (through Lenovo Vantage app), as of this writing.The laptop has only professional/scientific software installed and it's strictly used in a work setting in a climate-controlled office (i.e. no exposure to extreme heat/cold, humidity, dust, etc.) (scientific/professional software like statistic analysis software, Office, browsing company websites and other non-entertainment professional sites, etc.) and there have been no system registry modifications, no 3rd party driver installation, or anything outside of the normal functioning of the system. Windows has never been re-installed/reset from the factory-shipped condition, and I haven't even accessed the BIOS for the first time since it was purchased. There's > 250GB free from the 1 TB SSD, and RAM utilization never reaches > 50% even on the heaviest of workloads. IssueUp to Win 10 OS build 1607 back in 2016-2017, everything was running well. After installing builds 1703 and then 1709, and still now after the 1809 update (updated a couple of months ago, but nothing changed with that update), when I connect the laptop to external monitors (either to one or two 27-inch, 60-Hz 2K monitors [AOC Q2781PQ] outputting at 2K resolution), either...

I'm trying to use the Dell XPS 15 9550 with Windows 10, and I connected two external monitors, one to HDMI, one to Thunderbolt.
Only the one connected to Thunderbolt works, the other doesn't, it simply says no signal.
The cables and the port itself definitely work, if I switch to Ubuntu, both screens work.
On Windows, only the Thunderbolt works, even if I connect only one screen, the HDMI output doesn't work. I tried all combination of screens and cables, and in all combinations it is always the Thunderbolt output that works.
I'm on the latest updates with Windows 10. Latest NVidia drivers. Tried the latest Intel graphics drivers from the Dell site, also the latest ones from the Intel site.
One extra information: some forums suggested checking the NVidia Control Panel, but there I only have the "3D Settings" node in the tree, nothing else.
(I've googled a lot and read all the forum threads I could find, but nothing worked.)

I have a P50 with the Intel 530 video and the HDMI and Thunderbolt ports have stopped working.  Lenovo has replaced the motherboard and they work on the tech's flash Ubuntu OS so it's not the hardware. On 10/24, during the Lenovo or Windows scheduled updates, I see some changes to the video driver.  That's when they stopped working.  I tried roll back but it doesn't work.  I have read previous posts on P50 HDMI issues and have updated the BIOS, Firmware and Thunderbolt software.  I've run all Windows and Lenovo updates.  Of particular importance, Lenvovo keeps trying to push a large "Thinkpad Video Features" update on me but it won't install.  It says it is for Nvidia N16S and Quadro 16P so that makes sense to me, I just don't know why it keeps trying to push it down to me. Anyone experience this issue?  The screen shots show the Lenovo update they are trying to push on me and the updates to the display adapter driver that occurred on 10/24.  Since then it just hasn't worked.

Hello. Yesterday Iīve received my new Yoga S740 laptop and I was really looking forward to this laptop, but after using it for a day I am a bit disappointed with 2 things: - Battery life - I have the UHD version so I expected it not to be so great but it is even worse than I thought. Only about 3-4 hours. But this is something I can probably live with, not like the second problem. - FAN NOISE - even when doing simple tasks such as watching youtube videos or netflix, the fans start spinning and they are just loud. Sometimes itīs such loud that I am just waiting until the laptop starts flying around my room like a drone, because the fans sound like an airplane before taking off... When connected to a charger, the fans are almost constantly on. Also, the CPU is always working on high %, and the dedicated graphics is constantly at 0%. I have the 14 inch version, UHD 4K display, 16GB Ram, i7-1065G7, GeForce MX250. If these things can be somehow solved, I would really be glad to know how. Thanks!

I discovered this weird issue yesterday.For some reason, whenever I am plugged into AC and when Bluetooth is on (I've tried with two different mice), whenever I shut down my PC soon after booting it up, the computer shuts down, and then proceeds to turn itself on again a second later. I have disabled all the wake to boot settings I can think of, disabled fast startup and even resetted the BIOS but same issue. The problem doesn't manifest if:- I am using the battery- I turn off Bluetooth or- I wait a minute or two before shutting down It somehow seems that before the Bluetooth driver is loaded fully, something is causing the computer to restart instead of shutting down. Does anyone else ever experience this issue?
