T480 usb-c > miniDP > DVI External monitor not working

Q: T480 usb-c > miniDP > DVI External monitor not working

Hello,I have ThinkPad T480 and want to connect Lenovo L2250p external display (it has only DVI and VGA inputs) The display is currently equiped with miniDisplayPort to DVI cable (I used it with older T450)I borrowed USB-C to MiniDP(female) adapter, and try to connect USB-C Thuderbolt 3 port, but the signal didn't went through. iThe adapter must be working because in office I tried to connect the same way also Projector beamer (equipped with MiniDP>HDMI adapter) and signal went through. I thought the USB-C Thunderbolt 3 port is capable of sending DVI signal, or is there too many conversions/adapters connected? Does anyone know what can be the problem? Thanks a lot.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

I recently received an XPS 12 9250 and a WD15 dock. I have followed the driver installation and troubleshooting steps as outlined in the 2 sticky posts. I have gone back and updated ALL the available drivers that are labeled "urgent" and "recommended". Everything seems to be working EXCEPT external monitors. I have 2 Dell U2414Hb monitors that are DP daisy-chained. I am using a miniDP to DP cable from the dock to the DP input on the first monitor, then a DP to DP cable from the DP output on monitor #1 to DP input on monitor #2.
Currently I have a Dell mouse and keyboard, a 1TB Western Digital external HDD, a charge/sync cable for my mobile phone, Creative Labs speakers, and a CAT5e/RJ45 ethernet cable attached and all appear to be working normally.
I would appreciate some insight.

EDIT: I should note that I have a Microsoft Surface Pro 3 that was working using the same monitor setup.

Hi, I'm a bit confused after checking out the spec sheets of the T480 and T480s. Sometimes I read it has 1 USB-C port and sometimes it seems to have 2...  What I would like to do is to:- Charge the T480(s) via USB-C adapter- Connect a USB-C external monitor via USB-C and power the external Monitor via that USB-C "cable" Both at the same time. Is this possible with the T480/T480s without using a dock?

Hi, I have a new t480s with the intel uhd 620 driver, windoze 10.  Most of the time it is docked and an external monitor on displayport. Whenever the monitor powers off the windows all resize to what looks like the size of the 480 screen, so I have to rearrange everything each time.  Anyone find a fix or workaround?

I have a T480 with Windows 10 Pro connected to a Dell U3415W monitor via a DisplayPort to HDMI cable via a 40AJ0135US Ultra Dock (DisplayPort side connected to the docking station, HDMI connected to the monitor).  While using this setup, I will occasionally (sometimes quite frequently) get black-outs in the monitor for a few seconds and then the display returns without issue.  Its extremely annoying and interrupts my work.  Often, restarting the laptop will help resolve it for a while but it always returns in some fashion. I have run the ThinkPad Docking Station FW updater and it said everything is up to date.  Additionally, Lenovo System Update is 100% updated.  Any suggestions would be greatly appreciated.

This model is with Xeon CPU, Quadro P2000 graphics card and 1080 screen. The model of the monitor is Dell U2713HM.  When I connect my P52 to this dell monitor via a miniDP to Displayport cable, the monitor model is recognized in "Nvidia control panel" and "Display settings" of Windows, but in Display setting it shows "second display is not active". The screen remains black with a floating window: "no signal received".  Attempts so far: - In BIOS, I tried switching the graphics option from "hybrid" to "discrete", and set the start-up delay to 10 seconds. When I restart, the start-up Lenovo logo and the BIOS interface is displayed on the external Dell monitor. However, as the machine enters windows, the external display goes black (and so does the laptop display, until I unplug the cable).  - Also, I tried the miniDP to DP cable on other machines and the same screen. Works fine.  - When the laptop is connected to the same screen via a miniDP to DVI-D connector and a DVI-D cable, the Dell display works, regardless of whether I am in "discrete" or "hybrid status".

Could it be that the port died, or is it a software error?

Surely it's possible to manipulate it somehow? Surely windows can run both audio services, so my Realtek HD audio and AMD GPU audio would run at the same time! :/

It would be ideal as sometimes my lass likes to watch me play the odd game but she prefers to stay in the living room as im based in my passage lol. But i would prefer to still use my pc SPEAKERS * and not just getting audio through the graphics card. I know i can switch it over to what has sound, but i would find it convenient for both.

Audio is set up that you can only have one "default" playback device - thus either the "Speakers" (sound card) or the HDMI.

Hello. What might be happening is after you connect to the external display, the audio switches to HDMI audio. To get the audio to emit from the laptop's speakers again, go to the Windows Sounds dialog and make Speakers the default playback device (right click). You might have to do this every time you connect an HDMI cable.

I bought a T480 with an HDD, but I've since bought a Samsung 960 Evo and installed it into the laptop bay, and I want to clone the HDD to the SSD by booting from the HDD externally, but that doesn't work. I'm using a Sabrent USB 3.0 hard drive adapter kit to power and connect the HDD externally. I looked around for solutions just can't boot the HDD externally, even after going to BIOS and disabling secure boot and changing UEFI/legacy boot option to both.

A:T480 can't boot from external HDD?

Usually one must format the SSD before use, then connect it with a USB adapter to clone the existing HDD to it.
 
Steps that I employ...
 

Purchase SSD
Read SSD user guide, download manufacture software
Format SSD using manufacture software
hookup SSD to target computer via USB (notebook) or SATA (desktop)
Clone HDD to SSD via manufacture software / thrid party software
Verify information on SSD matches HDD
Remove HDD, replace with SSD
Boot the computer (notebook) verify installation / cloning works
Store HDD in safe location (as back up device)

This procedure works 99% of the time, but there is always the 1% that I have to work around otherwise.
 
Good luck.

Hi, first post!

I have an ASUS VW246H, 24 inch external monitor connected to my two laptops, one via HDMI, and another via DVI (viewing one at a time ofcourse).
My new laptop (Dell xps 17) has had the dual display running smoothly until right now (it was running just few hours ago!) and now it doesn't work!!
I plug in the HDMI cable, the monitor detects that something is plugged in, turns black for a sec, and then just displays "HDMI No Signal".

p.s. in the past hour I did boot into my second partition (Ubuntu, Linux) which doesn't have a dual monitor setup but I by accident left the HDMI plugged in. I 'think' I have done that several times before without anything going wrong. Dont know what happened this time!

p.s.s. I have tried to go in monitor settings on windows 7, look at the NVIDIA control panel and it cant find any external monitors. I have also tried toggling Fn + F1 which is the external display switch.

I have a Lenovo G50 running Win8 32bit. I have two external monitors both Asus with VGA ports. I successfully configured one of the monitors to the VGA port. However I have not been able to successfully get my 2nd external monitor connected using the HDMI port. I have a VGA to HDMI adapter for the monitor but it's not working. To rule out any issue with the 2nd monitor, I was able to get it to work by disconnecting the VGA cable from the first monitor and connecting it to the 2nd monitor. But again, no luck using the HDMI port with a VGA to HDMI adapter. So I'm fresh out of ideas. Had anyone been able to resolve this successfully with this setup? And if so, how?

Hello,

Yesterday my new laptop arrived, Windows 7 (64-Bit) pre-installed, I've downloaded all the updates; there are no other issues with this computer.

The only problem I'm having has to do with the external monitor; it's a IBM (6332) E74 monitor. Windows 7 detects and correctly names the external monitor E74, but the monitor just flashes no signal. I also located and downloaded the the IBM E74 drivers .zip file, but Windows 7 , says it is already using the latest drivers and ignores them.

Any suggestions would be great, thanks.

Ever since updating to Windows 10, my Yoga 2 Pro (model name 20266, Mfg Date 14/08/2014) is unable to connect to an external monitor. Tried a few TVs and a projector using the micro HDMI port. I've connected other computers to each of the monitors so I know they work. I understand how to use WIndows intimately (35 year old software engineer at Google, been using WIndows 20+ years), trust me, this is not a case of me forgetting to use Windows key + P or anything like that. The mirco HDMI port itself (physically) is fine and was working great until the day I downloaded Windows 10. So unless it happened to spontaneously stop working on the exact same day i upgraded to WIndows 10, it's not a hardware issue either. The issue is that the external monitor is simply not detected, no matter my attempts to play with the display options.I have also run the Intel driver update utilty, but it refuses to update the driver because it says it's detected manufacturer drivers and tells me I should get the manufacturer drivers. Ok, so I went to the Lenovo Yoga 2 support website, the latest driver they offer on that site is 10.18.15.4240. The driver update doesn'tmake a difference. Now, if you go to Device Manager > Display Adapters > Intel(R) HD Graphics Family, right click and selected "Update driver software..." it will download an even newer version (10.18.15.4279).

I have a Windows 10 laptop and an external monitor. The monitor was working perfectly for a few weeks, until one day I switched on the laptop to find that the monitor was no longer working. Going to 'Display Settings' only showed one monitor, and pressing 'Detect' said 'Didn't detect another display'.

After updating all drivers, then purchasing new leads and adapters for the monitor, I still couldn't get it to work. Then I stumbled upon the 'Hardware and devices' troubleshooter which, after restarting my computer, made it work.

Less than a week later, I just restarted my machine and suddenly it's not working again. This time, the troubleshooter isn't fixing it. Every time, it just says to restart my computer to finish applying updates/drivers but restarting doesn't help.

I've been running this Z580 for a year or so, and updated to Windows 10 a couple of months ago. Both the laptop display and an external monitor (HPw1907 vga) have been working fine. The other day, the external monitor just stopped working.   I check the device manager and the Intel HD Graphics 4000 display adapter is disabled, due to a Code 43. I have tried rolling back to an earlier restore point, I've uninstalled and reinstalled several versions of the Intel graphics adapter, up through the current compatible one. The most recent display adapter driver from Intel is apparently not hardware compatible with this adapter. The funny thing, is that the driver wants to work! On booting, while the black and white Lenovo splash screen is displayed, with the little circular Windows logo circling around, I can move the cursor back and forth between monitors. As soon as the screen turns blue (I assume with Windows drivers loading) the external monitor blanks out and I'm back to one screen.  Based on that behavior, I'm wondering if it's not a display driver that is specfically the problem, since I've loaded up the latest drivers several times, but if maybe a recent Windows update has sneaked in a driver or component for something else that is causing the Intel driver to crash.

Hello, I recently bought the Ultra Dock 90 for my T450s.  I have one external monitor currently connected through the dock.  When I push the power button on the docking station (laptop lid closed) to turn on the computer, the computer turns on, but the external monitor does not engage.  When I lift the laptop lid, there is no image on the laptop screen either.  The laptop is on, but does not respond to any key stokes on the actual laptop.  I then have to do a hard reboot using the power button on the laptop. If I initially power the laptop by lifting the lid and hitting the laptop power button, the compter boots and my external screen works.  I can then close the laptop lid and everything is fine. I know the power button on the dock should power the computer and external monitor on.  I am guessing there is a simple solution to resolve this, but I am not a computer person and need help. One thing to note - when I lift the lid after trying to power the laptop through the dock, I see that the Function Green Light is illuminated.  Not sure if this information is helpful in determining the problem. Please help! Peterrabbit33

I have tried updating the drivers and the hdmi port does work while I am connecting to my LG tv using the hdmi port. I have used various cables including the one that connects it to the tv however so far without success.

I am a bit clueless as to why it would work with the tv and not the monitor also my brothers laptop (which has Ubuntu) does successfully connect to the monitor.

Any help would be much appreciated and Thanks in Advanced

I upgraded to Windows 10 last week and everything was smooth.  Today when rebooting my system, the unit no longer can see my external display.  I have tried multiple other displays and none seem to work.  I have the latest video drivers for Win10 from the support site installed but it still doesn't work.  Any thoughts?

A:Yoga 2 Pro + Windows 10 = External Monitor not working via micro HDMI

I experienced the same - and also inconsistently that the system is going sluggish/lagging heavily. To fix problem with HDMI downgrade to drivers for Win8.1 - it works but hopefully Lenovo will fix this issue with Win10 drivers!? Overall upgrading to Win10 has been a bad experience (regarding the lagging of the system which usually occurs after 20-30 min after logging on). I've tried removing all third-party startup programs (including Lenovos) - but to no help. The frustration is increasing - any tips will be appreciated :-)

Dear all,
Wonder if you can help me solve a problem. I have just received an XPS13-9350 from the Outlet last week. It was certified refurbished.
I've tried to connect a VGA monitor to it via a USB-C to HDMI, then HDMI to VGA cable. The HDMI to VGA cable works perfectly on my Inspiron 15. The setup also works if I full power down the XPS13, attach USB-C to HDMI to VGA to monitor, and then boot up. The external monitor then works almost perfectly (with the exception of Netflix's video player which makes it flicker blue - Youtube and local video are completely fine).
What I cannot do is plug in this monitor whilst the XPS13 is on already - which is inconvenient as I move on and off desk a lot, and powering down the computer every time is unhelpful. Oddly, the monitor will also not be recognised if I simply Restart from Windows. I have to fully power down and plug everything in before switching the computer on again.
I have updated BIOS, video card and Thunderbolt drivers since and none of these has solved the problem. My system info is:
DELL XPS13-9350
Windows 10
Core i7-6560U, Intel Iris 540 graphics
8GB RAM, 256GB SSD.

I unplugged the cable to move my ultrabook, plugged it back in and now the connection with the external monitor is completely dead and won't come back, any chance its something other than the USB C port being broken? It worked fine for 48 hours.

I'm trying to connect my T480 to an external display using the left side USB-C ports. When I plug in the external monitor using a (USB-C to DVI cable), Windows 10 displays an error message like: "USB not recognized. The last USB device you connected to this computer malfunctioned, and Windows does not recognize it". According to T480 user guide those ports should work with an external monitor, so is this a hardware issue? All drivers are up to date.

I currently using a T460 and connect to two external monitors using the onboard hdmi & mini display ports.  I am not using the display on the T460 however. Which cable/adaptor I should buy to do the same on the T480?  Thanks.

Hi,my laptop monitor starts flickering an a regular basis as soon as I start Visual Studio. Not always and not only with VS but very consistently. I know that there were some unresolved flickering issues last year, so I wanted to check if there are any updates. This is a deal breaker for me. It seems to related to the software (e.g. visual studio) and somehow to the scale setting of windows. With the recommended "200%" I get it very consistently in VS. With "175%" it seems to be better for now.At two occasions my display flickered very heafily in VS and then shut down. Had to close and open lid to get it running again. I have updated my BIOS to the newest version (BIOS Version/Date LENOVO N24ET44W (1.19 ), 07.11.2018)Display drivers too. Intel: 24.20.100.6344, Nvidea: 24.21.13.9836Resolution is 2560 x 1440 x 59 hertz with 200% scale. Both the "recommended" settings.System Model 20L5000BGE BR Matthias

Hello I have been fighting issues with my external monitor not turning back on after sleep. I have it set to hybrid mode, I understand the other fix is to set it to discrete mode but my other laptop of the same type does wake up after moving the mouse in hybrid mode. I tried multiple things. 1.) Updated Intel Management Drivers and Software 2.) Updated Thunderbolt Software 3.) Used Graphic Driver Uninstaller and to no avail.  I also installed every update for Windows 10 on their web site. The other fix is to enable and disable the NVIDIA driver in the and that wakes up the HDMI port it seems, but that should not be the case, I would like it to just turn on with the flick of the mouse or button like my other laptop. Is it a failing graphic card of Nvidia or Intels end? I do notice after the monitor sleeps the NVIDIA drivers control panel settings go missing. I already uninstalled completely and reinstalled the drivers but my computer is still having this problem. Are their any suggestions on Lenovo's end or fixes? I bought this laptop from Amazon and I also joined a 3 year support service from them.

A:Lenovo P50 - HDMI External Monitor Not Working After Sleep (My Other Laptop of the Same Kind does)

Have you compared the Power Option settings on the two laptops to see if they match as well?Do the two systems share the same monitor, and if not, how is your monitor configured, does it have an option to set the input source to HDMI vs. automatically detecting the source?When in the mode where the screen does not turn back on, what happens if you press the following key combination Windows Key + Shift + Ctrl + B  (forces a reset of graphics cards) do you hear a beep and your screen wake up?     That key combination sometimes works to wake the monitors, and while not a solution, it may be a work around until you find a permanent one. Best of luck,
