External Monitor WITHOUT Using Thunderbolt Port (Yoga 720)

Q: External Monitor WITHOUT Using Thunderbolt Port (Yoga 720)

Hello - I wish to connect my 24" Dell monitor (it has every port imaginable) to my Lenovo Yoga 720 WITHOUT using the Thunderbolt port. Is this possible? I am a Jazz musician and I with to use the external display for (1) reading complicatedf [e.g., classical piano] sheet music and (2) for use with DAWs (digital audio workstations, such as Abelton, Pro Tools, etc., where there is LOTS of info crammed in tight and a large monitor is needed). My Yoga's TB port is used for a 500 gig Samsung external hard drive. The Samsung houses my music programs (e.g., the DAWs, Ivory piano, Easy Drummer, etc.), and I placed them there for the fast speed (this really helps eliminate the latency on the pianos). I don't need fast speed with the monitor; my prior Lenovo G780 worked just fine with my 24" Dell monitor; the G780 had an HDMI port. I don't find a "TB dock" that has (1) HDMI, display port, etc. AND (2) another TB port. Does such a thing exist? I've tried the crappy "USB montitors." They (1) suck and (2) are not 24". Am I screwed here? Thanks, - Jeff Newton (Jazz saxophonist and pianist)

I recently purchased an XPS 15 9550 with i7, 16 GB RAM, 256 GB SSD, and GTX 960m dGPU that I have connected to a 27-inch QNIX qx2710 2560x1440p external monitor. I have this connected through a Cable Matters USB-C/Thunderbolt 3 to DVI-D adapter and cable.
The monitor and everything seem to work fine at 60hz, except for every time I unplug, turn on, or restart the monitor/computer the first five or ten minutes of use is plagued with constant screen flickering and flashing. After ~five minutes the monitor seems to stabilize and will only rarely have a single screen flicker. 
I have read other forum threads describing similar issues with different monitors/cable setups and that there is likely an issue between the wifi card and thunderbolt port. The common recommendation is to turn down the wifi output percent to 75%, however the Killer wifi card on this computer does not have an option under advanced settings to turn down the power output. Has anyone had any luck doing this on a recently purchased XPS 15 with the Killer wifi card?
The cables and adapters are new and the BIOS and all drivers are up to date. Other than the wifi issue, does anyone have suggestions or solutions to this screen flickering problem?

I bought a Dell XPS 13 9350 in December and I wanted to connect it to an external monitor via the thunderbolt port. I bought an type c to hdmi adapter off amazon and it connects. (Actually bought 2 and the problem persists). But occasionally both my screen and laptop will turn black then back on again. This causes my video that i'm playing to either freeze/crash (netflix/youtube) which is SUPER annoying. It goes from occasional to quite often. It's really random.

My drivers are up to date, cable is new and the monitor is new from boxing day. 

Any help is appreciated :)

hi, I have setup one of my faculty with a Yoga 920131KB plus Thunderbolt 3 Dock. He has an existing monitor (Samsung Syncmaster P2450) that should support 1920x1080. Seems to be current on all drivers and patches under Win10 EDU version. (Including the CCG4 Firmware Update to v55). We are using the HDMI output from the dock. If we try to configure extended desktop to the Samsung monitor at 1920x1080, the screen extends off both sides about half an inch. Maybe also a quarter inch over at the top.  As a work-around, set at 1680x1050, video generally works as expected, but the display starts about 2" in from either side. Generally I don't like using add-on utilities (prefer to just use standard windows built-in options), but somewhere along the line this has the Intel Graphics HD Utility.  I was using that to switch resolution, the Windows settings seemed to track along with changes in the Intel utility, but still overscanned the display.  I played with some other settings in the utility about Display Scale (other than 100%), didn't seem to change anything. A second problem occurs with this setup: when the laptop is used at home, put to sleep, then plugged into the dock, the screen is displayed on the external monitor at maybe 200% (?).  That is, you only see the central portion of the image.  No fiddling with settings seems to correct it, but rebooting usually fixes it. The second problem also occurs with a similar Yoga 920 + Dock (d...

Also wanted to mention something I noticed while working on this: I saved a log from the Intel Utility. There is a section in there about "Maximum Image Size". This seemed to be correct for the laptop display (12.2"x6.69") but the Samsung was listed at 6.3" x 3.54"    It is a 24" diagonal display, so that is obviously wrong, but I don't know that it is important. Intel(R) UHD Graphics 620 Report Date: Monday, February 5, 2018Report Time [hh:mm:ss]: 1:21:19 PMDriver Version: 23.20.16.4849Operating System: Windows* 10 Education (10.0.16299)Physical Memory: 16225 MBVendor ID: 8086Device ID: 5917Device Revision: 07Graphics Output Protocol (GOP) Version: 9.0.1066Current Resolution: 1680 x 1050 Display Type: DigitalDDC2 Protocol: SupportedGamma: 2.2Connector Type: DisplayPortDevice Type: DisplayPortMaximum Image SizeHorizontal Size: 6.3 inchesVertical Size: 3.54 inches

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...

Have read others with similar problems and different types/models of Yoga laptop and none the wiser. Also finding the screen attached to my laptop very diffficult to read . Often text is truncated and I have to adjust zoom to 50% to see whole window. External monitor will also solve this problem. Have downloaded new drivers but discovered they're for different Yoga models so unsurprisingly they don't work. Any suggestions gratefullly accepted.

Hi, I think I'm having some problem with my Yoga 920's thunderbolt port. I bought a StarTech thunderbolt 3 dock. When I first time plug in the dock, everything works fine the thunderbolt software pops up and ask me the authorized the new dock. And I click always trust this device. Then the windows crushed with a blue screen and a QR code on it. After 920 restarted, and I tried the dock again, it was identified as USB 3.1 hub but no USB connection. And when I tried to open the thunderbolt software, it shows me the following warning.I tried to update the driver, but the installer said it was all ready. And then I downloaded HWINFO64 to check, I could not find the thunderbolt 3 controller under the PCI-Express X4 BUS. Is that means my thunderbolt 3 port is broken? What should I do with this? Btw, when I plug in the thunderbolt 3 dock, the powersupply is also connected, and the dock also provide the power, two power supply input at the same time, will that be a reason of the crash which also burn the thunderbolt 3 controller? Thank you.

I'm using the thunderbolt port for a single connection to a Dell usb-c dock (power in, KVM out, speakers, network, etc.).  The 720 charges real slow and the battery status message (in Lenovo Settings app) states that the "AC adapter cannot provide enough power for normal operation of your computer".  The Dell usb-c docks are powered with a 180w power supply that provides 60w of power to the computer, which is more than the 45w power supply that comes with the 720.  I have tried 3 different Dell docks, including a Dell thunderbolt 3 dock with a 240w power supply. I have to believe this is an issue with the Thunderbolt 3 driver on the 720 or something BIOS related.  BTW, the 720 has Windows 10 pro loaded (updated from the home version loaded by default) and Bitlocker enabled.  Don't think these changes have anything to do with the issue. I purchased Lenovo's thinkpad usb-c dock (which states that it's universal) and hope it charges the 720.

I've had my x1 yoga 3rd gen for about a year now, and love it. I've been using a thunderbolt 3 eGPU dock (aorus 1070 gaming box) as a dock for about the same amount of time now, since it gives me the convenience power and portability. Other than the occasional visual glitches and restarts, I haven't had any issues when I unplug my laptop from the eGPU dock, or plugging it in. However, yesterday after I unplugged my laptop from the eGPU dock, my laptop kept making a "connected USB" and "disconnected USB" sound. It looked like my Thunderbolt 3 software app kept crashing and rebooting. I also noticed that none of my usb c/thunderbolt 3 ports were working; the laptop says it's charging with nothing plugged in, and when I tried plugging in a charger, it wouldn't charge. The only solution I found was to disable Thunderbolt 3 in the BIOS, but I'm not sure if this is a software issue, or if there's a part of my motherboard that's fried. Does anyone have any ideas or suggestions for troubleshooting?

Hello there, I recently bought the Yoga 920 and tried to connect the HP Omen Accelerator for use as an eGPU. However, something seems to be wrong with the thunderbolt connection. When I connect the accelerator, the device connects for a split second (typical USB connection sound) and then immediately disconnects again (typical USB disconnecting sound). I tried different setups for the eGPU, I tried every possible driver I could find, I tried a different Thunderbolt cable and I followed every step on the Omen Website, nothing changed. Now, after looking at the Thunderbolt Controller Driver it tells me that the Controller-Driver-Version as well as the Networking-Driver-Version are unknown. I suspect, that there is something wrong with the thunderbolt driver/frmware. Could it be that somehow the drivers aren't recognized? Any ideas as to where I could continue from here? Any advice is appreciated! RegardsMrKnowNothing Edit: To anyone who has the same problem. Sometimes the easiest solutions are the best. Two things could'Ve been the problem: 1. My antivirus blocking something. I uninstalled it and installed a different one, while I was working on the Omen problem, can't verify if that was the reason though. 2. I had the Thunderbolt Programm Window open when I connected the device. Not sure if I had tried that before, but it worked. So, it was probably either the antivirus or the thunderbolt software not being open before connecting.... Read more

I have a P1 GEN2 OLED. While the internet is flooded with complaints of the OLED screen itself, the thunderbolt 3 port of my P1 GEN2 magically stopped working for no reason.  I have been using the laptop with an external display ever since I got the laptop. All went well. Suddenly from yesterday, the external display starts turning into a blue sreen with "NO SIGNAL" shown on it.  I had a windows cumulcative update (KB4532693) and windows security update (KB4524244) yesterday and I suspected that the update might be the culprit. I rolled back the OS. No change. Still NO SIGNAL.  I searched this Forum. Played with Thunderbold 3 menu in the Bios. Everything was enabled and every single option of "security level" was tried. Still NO SIGNAL.  I checked Intel Mangaement Engine software. It is already the latest version. Reinstalled it. Still NO SIGNAL.  I checked Nvidia driver. Latest version already.  In sum, the problem is: the thunderbolt port is still able to power the extenal display but just simply does not pass signal to the external display. HDMI port, however, still passes signal if use an HDMI cable.  I want to give it a shot here to see if anyone has experienced similar issues and how they sovled the problem before I call Lenovo technical support, the staff of which does not seem to know more than some people here on this Forum.

In the white area of the dialog box, right click and make sure both "show disabled devices" and "show disconnected devices" are both checked.

For my X1 Carbon 5th Gen I got myself a Thunderbolt 3 Dock (Gen 1) - (40AC). But right now the dock doesn't work as expected.I have connected a 1440p-Dell monitor via DisplayPort. Also I conntected a 1080p-Panasonic-TV via HDMI. The manual of the dock suggested to use a certain DisplayPort-Connector, which I did.I'd like to switch on my ThinkPad via the power button on the dock and then wake up my Dell monitor from sleep. Right now the Dell is set as primary display. If needed I'd like to switch on the TV as a secondary display. The ThinkPad should remain closed and only the external displays should be used. In the BIOS of the ThinkPad I alread configured, the an external display should be used prior to the internal one.Right now the following happens: I switch on the ThinkPad via the button on the dock. The Dell monitor doesn't wake up. Only when I switch on the TV (Panasonic 1080p via HDMI) also the Dell monitor wakes up and shows the content. I'm rather lost how to solve this behaviour. I already checked the BIOS version of my ThinkPad and updated it - nothing changed  Has anyone any idea?

I recently got a Dell XPS with Thunderbolt 3 technology for work, but also have a 2011 iMac with Thunderbolt.  I am wanting to use the iMac as an external monitor for the Dell, so I found a Thunderbolt 3 to Thunderbolt adapter to utilize TDM.  However, I have not had any luck making it work when pressing command-F2.  Through my research, I've found that using a pre-2011 iMac with a mini display port and a PC with a mini display port has worked no problem.  I've also found that using a post-2011 iMac as an external monitor with a PC should also work no problem if both computers have Thunderbolt technology.  In addition, I contacted Apple Support and they told me my connections should work since I have stepped the Dell's Thunderbolt 3 down to Thunderbolt, and connected the two machines via a Thunderbolt cable.  I am able to tell that my Dell recognizes the iMac, but have no way of knowing if the iMac recognizes the Dell.  Is there something that I'm missing?  Is there software that would make this work?  Has anyone had success getting this to work?  Any input would be greatly appreciated.  Thanks.

Ok.. I'll try to keep this breif. I bought this laptop SPECIFICALLY for the capability to run 2 external monitors via Thunderbolt 3. I have spent thousands of dollars on the laptop, monitors, and cables and put hours of research into making sure everything was compatible and it won't work.  My setup is as follows: Thinkpad T580 with TB3 portTB3 to Dual DisplayPort Adapter(x2)Monitors are both 32" Samsung 1080P monitors at 60hz (NOT 4k) Here's what I have done: Updated display drivers directly from Intel(newer than Lenovo provides)Updated BIOSUpdated FirmwareBought MULTIPLE adapters thinking it was possible an adapter problem.Bought MULTIPLE cables thinking it could be a cable problemI called Lenovo tech support and, after 10 minutes of convincing the tech that my laptop even has a TB3 port he obviously was unable to resolve it so I was mailed a new motherboard and a tech came to my house and swapped the board out. Same issue.  The laptop detects only ONE monitor at a time. If I plug them both in to the displayport adapter, one of them will work, the other will say it's not connected. If I unplug the monitor that is on, the previously undetected monitor will immediately be detected and turn on.  If I plug the undetected monitor into the HDMI slot it will detect and output. But this is NOT the functionality that I have spent thousands of dollars for.   I am out of ideas and now quite sure that, even though the marketin... Read more

Dear All: i have the X1C7 with the UHD screen and a 10th gen processor connected to the "AN" Thunderbolt 3 Gen 2 dock. the dock initially also had external speakers connected to the dock via the miniplug in the front of the dock. when i removed the miniplug and external speakers after around a 2 1/2 week usage period with the external speakers, the external screen started to flash a brief blank moment (< 1 second, maybe 0.5 second).  these blank screen flashes are black screens, and may happen every few minutes or much longer. may i ask if anyone has experienced these flashes of black screens? fyi:  i did make sure that the DisplayPort output was securely plugged in. thanks in advance.

Hi,
I myself own an XPS 15 9550 and noticed that I was not getting the full Thunderbolt 3 speedover it's Thunderbolt 3 port. I expected speeds around 2700MB/s, because of the overhead withthe theoretical gross speed of 3870MB/s, but I only ever got 1400MB/s out of it.
I did some digging and found out that none of the XPS notebooks with Thunderbolt 3 are evenable to achieve the full TB3 speeds, because they are only connected with two PCI Express lanes (x2.3).You can read more about this on the following links:Dell Subreddit PostChipset Digging on Forum

Thunderbolt 3 and the promised speeds were the MAIN REASON I even bought this notebook.I feel very cheated here.

After the Thunderbolt firmware update, I'm now getting terrible white level clipping on my external monitor. I'm a photographer using a 100% Adobe RGB monitor calibrated with DisplayCal and a Spyder 4. Until updating the firmware, I had 0 problems. Now, compared to before - and compared to other computer attached to the same monitor - the contrast is completely wrong. All RGB values including and above 244 are clipped to 255. This is obviously a huge problem. I've uninstalled all of my calibration software, and removed all my color profiles from Windows Color Management, so Windows should revert to the default profile. Still, the same problem! What is going on? I never had this problem, until the update!

I have a Thinkpad X1 Extreme (20MF000CUS) connected to two external 4K monitors via Lenovo Thunderbolt Workstation Dock (40AN0230US). Windows 10 desktop extends to all 3 displays.Everything works really well except for a major annoyance: normally I have a bunch of apps/windows I leave open on all 3 monitors. Whenever I put the laptop to sleep and I then resume it later on, all app/windows I left open are automatically resized, moved and stacked up on the primary (laptop) display. Is this by design? Anyway to prevent this behaviour?I noticed that the laptop display is handled by the Intel graphic card while the two external displays are handled by the nVidia graphic card. Could this be the reason?
