HDMI port not working - 'not plugged in'

Q: HDMI port not working - 'not plugged in'

Hello,I've been trying for hours to connect my external monitor via HDMI cable, but neither the laptop nor the Monitor sees eachother.I updated monitor's firmware to the latest and no result. Still, my computer displays that there is nothing plugged in the HDMI port when I insert HDMI cable. The monitor sees that I have plugged in something in the HDMI port, but doesn't receive any signal from my laptop.Would you please advise if there is any solution to this specific situation?Also, be advised that even with the latest video driver downloaded from your website, I am still unable to play on OpenGL video mode. I am looking forward to your reply. Many thanks in advance,

Purchased a new M715Q mini and upon connecting using the display port and HDMI for video was not being recognized. I then looked at the the USB mouse and found that it was not being recognized either. Tried all USB ports and none of them recognized the mouse. I have a 3 other lenovo products M900 series and 2 laptops and they all work with monitors and mice. I also found the unit getting extremely hot where the fan kicked on 3 times and turned off. Has anyone else had this issue?

I plugged my laptop into an integra 30.4 receiver via HDMI port (multiple ports) and with the receiver on the right device port and connected to a tv or a projector and I get no audio out of the HDMI port only Video. Video works great!

The laptop is an alienware laptop on Windows 10 (upgraded from windows 7 purchased November of 2011). The HDMI would transfer audio and video in windows 7 intermittently for a year or two. However, I had to turn the tv, receiver, and computer on in a specific order and eventually, approximately 1 hour of doing this each time I wanted audio I'd get the audio over the HDMI cable until I shut down....

I've been on windows 10 now for a while and never have gotten the HDMI audio to work. I kinda gave up but would like to use my laptop now to play movies to my new epson 4k projector and am unable to get audio to work at all. Video is phenomenal.

The HDMI port shows up in the device manager under sound devices. However, constantly shows "Cable not plugged in" whether the cable is or is not plugged in.

It's an older Geforce card - wanna say it's a Geforce 555. Also has an intel graphics adapter as well. I've done all the nvidia updates, windows updates, I've gone so far as removing the sound adapters and rebooting, removing the graphics adapters and letting them reinstall. The HDMI audio port always comes back with "Cable Not plugged in." It's staring me in the face constantly.

Hi everyone, the wifi connection on my Ideapad 500S-14ISK stops working when I connect to any external monitor via HDMI.

It works very briefly if I disconnect the wifi and connect again. Starting the computer while the monitor is already plugged in does not help.

When I plug in the HDMI port the computer doesn't say or even recognize that there is a cord plugged into it. The tv also shows no signal.

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.

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?

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.

Every time i need to do the ipconfig release and renew then it starts to work again.
I also heard that my coworker experienced the problem too when using windows 7, but the older computers running on xp never had an issue.

Does someone know is this some kind of problem that only windows 7 have?

Hi Gang,

The cord shows up as being listed on the TV as HDMI 2 but when I look for it on the PC I see nothing. I used to see LG TV. Not it is no longer listed.

I have tried rebooting, turning PC off, updating drivers, reinstalling the drivers and taking the card out and and putting it back in. Nothing works. What do I do?

I ordered a new cable but it keeps telling me to check power supply, cable connection, and the make sure it's on the right setting. I have 2 hdmi ports on the back of my TV but still come up with the same error condition when I switch them. It appears the port in the computer is not working anymore. I have tried everything but nothing works. I am running an ATI 4200 which is on the motherboard. Can this be fixed or would I have to buy a new graphics card to get it working again. I did swap the cables but still get the same results. Does anyone have any ideas because I have run out of them???

A:HDMI Port not working anymore

The only way to fix it is to buy a new motherboard, do yourself a favor and buy a new video card instead, Dells are not worth fixing. But if it`s under warranty well then that is a different story.

If that`s a laptop then your ONLY option is to replace the motherboard, very simple to do.

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.

Hi
I don?t know what Windows system you use on this notebook but the HDMI driver isn?t available since the HDMI port driver is part of the system and should be recognized automatically.

For HDMI sound capability you should install the right sound driver and should enable this in control panel -> sound -> playback device

In order the HDMI (digital out) would not be listed there, right click and choose:
show disabled devices, show hidden devices.

Usually the HDMI connection isn?t very tricky. Everything should run automatically.
Connect both devices using HDMI cable.
Power up the TV, then computer.
Now use the function key (FN key) video output combination in order to switch to video out (HDMI).

Note: the right HDMI channel should be chosen on your TV

That?s all

I have a T470 (Win10) connected directly to a ViewSonic VG2030wm via HDMI - no docking station. The cable is known to be good, as I used it with the same monitor with a T460 without the following problem: Intermittently and sporadically the screen goes blank. It does not matter what order I turn on the devices or connect the cables. Randomly the screen will go black - sometimes the image comes back within a few seconds; sometimes the image blinks on and off for up to a minute; sometimes the image is steady and the monitor is usable for an hour or two; sometimes the image stays off for so long (about 30 seconds) that I get a "No Signal Detected" message from the monitor, only to have the image return (sometimes within seconds, sometimes within minutes, sometimes within hours). ViewSonic does not offer any updates to the driver. All other drivers on the laptop are up to date. It does not have anything to do with what I'm doing, such as a loose connection. I use an external keyboard, and the laptop itself is on a box that improves airflow, so the only vibration to the laptop is what little is communicated thru the desk, and somewhat insulated box the box. Nothing I do can 'encourage' the image to reappear on the laptop, such as disconnecting/reconnecting the cable, turning the monitor on/off, etc. Any questions/suggestions will be greatly appreciated.
