HDMI Port stopped working (X1 Carbon)

Q: HDMI Port stopped working (X1 Carbon)

Please hope you can help! About a week ago the external monitor (connected through HDMI) stopped getting signal, when reinstalling the driver it started working again. Now it happened again, and I tried reinstalling again, but nothing. I have tried the cable/monitor and they work fine, its the computer/hdmi-port. I'm pretty sure it's not a hardware problem... The Intel Driver Update Utility doesn't help either, neither does Lenovo Solution Center. What to do, I'm desperate! Help is tremendously appreciated!! /Fredrik

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

I generally use a second monitor via an HDMI cable while working. However, it stopped working today.I checked these:Windows cannot detect a second monitor when HDMI cable is connected to the second monitor.HDMI cable which I use works if another device is connected to the second monitor.My computer detects my HDMI-to-VGA converter through HDMI port.My computer runs Windows 10 Home with latest updates installed.I suspect this is due to a driver error. How can I fix this problem?

HDMI port stopped working about a year ago. It had always worked on Windows 7 64-bit.  Also it worked on Windows 10 64-bit for quite some time.  I have HP Compaq PC with 3 TB HD with 2 new flat screen monitors each able to run as VGA or the
other way.  Had both monitors working fine.  Tried switching monitors, and everything else.  Plugged in, etc....,
I would like to simply download the correct drivers for the HDMI port, at leas for the monitor and graphics, install correctly, anin compatibility mode, I assume, and all I ask is that you please not lie to me and say I have to buy something. I'd appreciate
your expert help.  Everything works...need to install correct drivers in compatibility mode.  The correct ones.  In the correct places and know what to do if there is no "HD video, audio, and game controller" section, for example,
or "Graphics" section in device manager.

Thanx, Miguel

For the first couple weeks I was able to run 3x 1080p monitors just fine using two display ports and an hdmi port. This morning when I docked my computer I could only get two to work. I can disable one then enable another and get all three working but only in sets of two.  I tested two of my coworkers laptops on my dock and all three monitors work fine. Also when I boot all three work until the Windows splash screen then one goes dark.  If I try to enable the third one: It acts like it's connected but the display remains dark and I lose my mouse cursor. I can stll move the mouse and see the hover overs but the cursor is gone.  I'm thinking this is a windows driver/firmware issue. In device manager I see all three:   But can't seem to get all three to work at once.  I've tried reinstalling both the Thunderbolt drivers and the display drivers with no luck. Any ideas? I'd like to avoid completely reinstalling Windows as I know that'll probably be a suggestion.

I have a new Carbon X1 (5th Gen), fully patched Windows 10 64 bit, trying to connect to a 1080p HDMI projector. When I connect the HDMI cable to the port, the OS recognizes that there is a second screen, but I'm usually not able to get anything to appear on the projection screen--usually just "no signal" although once or twice I've had something from the laptop display externally (no apparent cause/reproducibility). I have a similarly configured Carbon X1 (3rd Gen) that works completely fine with the HDMI output, using the same HDMI cable, projector, resolution settings, etc. So that presumably would rule out any problem with the cable or projector system. Both the 5th Gen and 3rd Gen are configured to use the native 1080p resolution of the external display, but as noted the 5th Gen almost never works. I've also tried unplugging the USB-C and any other monitors from the 5th Gen to see if that makes a difference; also trying to different modes--second screen only, duplicate displays, extend displays--and none of these help either. Any suggestions for how to further troubleshoot or narrow down why the 5th Gen Carbon isn't able to get the signal through to the projector?

Is there a way we can change the touchpad Reverse scrolling option (Scroll --> Two Finger Scrolling --> Switch Direction) on the X1 Carbon through an automated way. We see that after Windows 10 upgrade, the scroll option on the touchpad has been changed. So doing it manually it works but we want to automate it either through a registry change or some other method. Yes manual changes works perfectly.

Hi all,

I've just recently got myself a new laptop (specs at bottom of message) and took it around a friends house and plugged it into their HD TV via HDMI - all worked well, the laptop recognised the TV straight away, optimized the display and away we went.

A few days go by and I decided to upgrade my own TV from an SD to an HD TV (Bush BLED24FHDL8) yeah I know cheap as chips, but it's going alright so far ... well except this problem pmsl.

Within 5 mins of setting up the TV channels I decided to plug my HDMI cable into the laptop and then into HDMI 1 slot on the back of the TV, I changed the input of the TV to HDMI 1 and.... nothing.

Going into the display settings of my laptop didn't show a 2nd display, so I changed various settings trying to get it to recognise the tv, but nothing, still no signal showing on the TV, and nothing showing on the laptop.

So I changed over the cable to the HDMI 2 slot on the TV etc and still nothing on the laptop, I fiddled with the settings again and still couldn't get the laptop to recognise there was a 2nd display, nor get any signal on the TV.

As a last resort I unplugged the HDMI cable and tried the VGA cable I have - and this decided to work, although no sound as I didn't have those cables plugged in.

When I plugged the VGA cable in, the TV and laptop recognised each other straight away and I didn't have to do another thing.

But I've still got this HDMI problem --- I've even gone out this a... Read more

Computer - HP 8710w, Intel Centrino vPro, Nvidia Quadro

I connected my HDMI cable to TV Hdmi port and PC Hdmi port but no signal on TV at all. With Vista it was plug and play (just needed to adjust audio settings on PC).

I have tried downloading updated drivers but to no avail. While connected pressing the Fn key and F4 hey does nothing, the computer has no idea that something is in that port. I think the port is somehow inactive or physically damaged.

How may i check to see if the port is working and how do i check if its software related?

Many thanks

Are you running more then one monitor at a time? If you are then you need to right click on your desktop and select "Screen Resolution". Then find the TV on the display device drop-down menu. Then check the box "Make this my Main Display".

Let me know if that works, if not I can help troubleshoot the problem some more.

I noticed that there was no Intergrated Camera driver in the list, I then decided to install it manually. I was then met with a "Can't find the device, Abort install!"I have attempted to use FN+F6 to enable and disable the camera, even with restarts in between. I have also gone through the BIOS and enabled/disabled the camera to see if it would then detect it and nothing has worked.Has anyone else had an issue like this and been able to resolve it?

Will not display on any monitor. Tried multiple different monitors. Updated all the drivers, from Intel, NVIDIA, and HP. Nothing works. Funny thing is that NVIDIA recognizes the monitor, name, make, and resolution. But no where can I find NIVIDIA recognizing the built in display on this computer. Intel recognizes the built in monitor, but doesnt see the external monitor.In the NIVIDIA contorl panel under system topology it details the HDMI port, its connected. So I got my IT people involved. They couldnt figure it out either. They tried everything. They believe that since NVIDIA sees the external monitor, but "Multiple Display Cloning" is "Disabled" (Unable to enable it) that NVIDIA doesnt recognize the built in display, it thinks the built in display is the monitor. When the external monitor HDMI is unplugged, the NVIDIA control panel clears out as if no monitor exists at all. This is a brand new HP zBook that I have had for a couple months. Been fighting this issue ever since. Desperate to get my monitor working I recently went and purchased a VGA to DVI converter and DVI to HDMI converter. That doesnt work either. I feel defeated, crushed by an HDMI port.
