Preferred Solution: my HDMI port suddenly stopped working to my extra display

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 have a duel monitor setup where one was plugged into HDMI and the other into VGA. Both were running off of my NVIDIA graphics card (i also have Intel 4000 Graphics which came with my processor but is not in use).
When playing a game - my HDMI monitor just shut off. My VGA continuing to work.
I have tried many things such as reinstalling drivers but nothing has seemed to work. My Intel 4000 Graphics are failing to work also. I am yet to look inside of my PC to see if anything has moved out of place.
I've tried googling and I've found nothing of use. If anyone has a solution that would be great! - P.S I'm new to the forums

A:HDMI suddenly stopped working.

Hi, I use HDMI output to connect to my TV a lot. One day I was using it without issue, disconnected the cable to move the laptop and when I reconnected it didn't work. I tried using (Win + P) and another dedicated keyboard shortcut (Fn + F4) to chage the display, neither would restore the TV display. I can still connect to a projector using VGA and I know the TV and HDMI cable are still good because they both work with my Windows 8 laptop and bluray player.

I'm just not sure how to start troubleshooting. I don't see display ports in the device manager and the graphics card says "This device is working properly." So where do I go from here?

Thanks in advance for any suggestions!

A:HDMI out suddenly stopped working. Don't know how to troubleshoot.

Do some quick checks on the cable. First you can think about if you have bent the cable in any weard ways. If so that could have damaged the cable. You are NEVER supposed to fold a cable as it can break the small cables inside of it.

Secoundly have a look at the pin's on each side of the cable, Are any of them bent? If so this could be the cause.

Hi Turbonis!
This article from Microsoft support page may help you understand and fix the issue through a few steps like scanning for hardware changes and resetting the USB controller:
If not, then it could be that the USB ports have just died. For that, you'll need to take your PC to a professional to determine the damage.

Suddenly my HDMI 2 connection with the LG TV has stopped working.

When I switch in Input to HDMI 2 it comes up on screen Connecting as usual but then reverts to no signal.

I?ve taken the lead out and in again but it still won?t connect.

I note when researching this problem some people are suggesting graphic driver updates and I did start with a Microsoft thing but cancelled cos I was worried in case it was not legit or virus etc.
I'm an oldie and nervous of this stuff.
I haven?t changed anything ? it was working earlier but just didn?t work when I switched as usual to HDMI 2
I do hope somebody can help me
Many thanks

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?

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

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

Greetings. I have a T480 connected to a Pro docking station (the one with the side connectors). I am triying to connect it to an HDM TV via a DP 1.4 to HDMI 2.0 active adapter. Windows detects a connected screen, and the TV detects input in that channel, but there is no image nor audio.Things I have tried already:- Updated thunderbolt firmware and drivers, and everything available from Lenovo.- Tried both intel graphics drivers from their website and the Lenovo OEM ones.- Tried a Variety of refresh rates and resolutions.- Trying the adapter In a x220 displayport: it works without problems, so the problem isn't the cable.- Testing a different, passive adapter: It works with the T480.- Numerous reboots, disconnecting the dock and everything from it, and connecting one device at a time.- Tried both displayports with each of the 4 HDMI inputs of the TV.- Thunderbolt assist mode in bios disabled. And that's all I remember from the top of my head. Any idea as to why is this happening?

I have been searching in several forums but have not been able to fully fix this problem. It was fixed temporarily and failed again.
This the system I have:

HP TouchSmart tx2 tablet pc with Windows Vista Service Pack 2 (Home Premium) x 64 bit
AMD Turion (tm) X2 Ultra Dual-Core Mobile ZM-82, 2.2 GHz
ATI Radeon HD 3200 Graphics

I have been working for over a year with an external display Dell ST2310 flat screen monitor and working fine with the "use external display only" setting . From one minute to the other both screen went black so I forced a restart and again the same problem. I decided to manually disconnect the external display by unplugging the VGA cable from the laptop which automatically switched back to the main display as it would if I disconnected the display. When I plugged the VGA cable back in again the same issue both screens were fully black. I disconnected once again the VGA cable so I could change the settings in Windows Mobility. I plugged back in the VGA cable after changing the settings from "external display only" to "mirror monitors" and after playing for a bit with the Windows Mobility Center I got the external display to work back again to my regular settings: "external display only". This solution lasted for a day and now the main display works and the external display screen is fully black.

My 3 year old Inspiron 7537 (Service tag: 56H5812) w/ Windows 8, which until this time had been 100% problem free recently would not turn on. I would press the power button and nothing would happen (even w/ AC adapter plugged in)- even the charging indicator would not turn on. This was the case even when I tried using a friend's charger. I left the system pluggged in for a few hours and it eventually began to charge and has since been turning on reliably w/ either battery or AC adapter power.
The bigger problem is that since this time the LCD does not display any image at any time- not even a very faint one. Interestingly enough, the HDMI output still works fine (currently typing this w/ the laptop plugged into my TV). Also, the touchscreen somehow continues to work flawlessly. I.e when the laptop is plugged into my TV if I touch center of the (blank/dark) laptop screen it shows up on the TV as that part of the screen being touched.
My immediate reaction to these issues was to check for updates. I performed all available Windows updates and then I logged onto the dell website and used System Detect and the "detect drivers" options to find appropriate drivers and updates for my machine. A BIOS update was identified (7537A14.exe, A14).
I have spent hours trying to update the BIOS but keep getting either an "ERROR: Unknown or invalid AC & DC power condition." This happens with the AC adapter plugged in (including when I use my friend's). It persis... Read more

I have a Dell Latitude E7440, Windows 7
The HDMI-port has been working fine for two years attaching to varius units - projectors, TV etc.Last year it stopped to work with one projector (where it uasually works) so I just used the docking station and an VGA cable instead - did not have time to look for what went wrong. After that, a few months later, the next device stopped to acknowlagde the HDMI signal, now it was my standard Samsung LED-TV. OK, so I guessed that the HDMI-cabel was the problem, but after testing several HDMI cables with no luck, I rather thought that the problem was a physical problemen in the HDMI port at the back of the laptop. To shame, hard to fix that. I now realized that there actually where another digital port on back sida of the laptop, the mini displayport -maybe that one is working? So I bought a converter "mini display port to HDMI" - and whooho - it worked. But just for a few days.. :-(
Now I am back to use the docking station and VGA and as you can understand - that is really anoying.I have been using laptops for + 20 years now so I do think I have some experience. It is not an "Fn + F8" problem or a cable problem. Any suggestions?

Hallo Community, I am using my X1 Carbon gen 4th with an external Monitor via HDMI cable. Now i would like to try to add another external Monitor on it. Without any docking station would be perfect. I notice that there is also a mini display port on my device. I suppose I can connect one monitor via HDMI and the other with mini Displayport? Will these two monitors work together at the same time? I would like to ask, if anyone has experience about that?   Thanks for the  inputs in advance!

The title says it all. I'm very frustrated with this problem since I really need to connect my laptop to an external monitor for work. I've read and tried all relative topics in this and intel forums (e. g: https://forums.lenovo.com/t5/Lenovo-Yoga-Series-Notebooks/Yoga-920-can-t-connect-to-any-external-mon...), have done all steps mentioned (including firmware, bios and windows update, windows reset, ...) but the problem still persists. Apparently, most users that had faced the same problem been able to get it worked after installing "Type C Firmware for Windows 10 (64-bit)" or the BIOS update provided by Lenovo. I installed them successfully but nothing changed. I am sure it is a software issue since there is no sign of any hardware one (all devices are fine as device manager shows and diagnostics app found no problem). It was just working fine until suddenly stopped working (probably after some recent windows update). I would greatly appreciate any help.

I'm using a Dell U3415W monitor. My video card is AMD Radeon RX480. The monitor is connected via DisplayPort to my computer. The monitor is connected via HDMI to my work laptop. When I want to switch over to HDMI, it acts as if I shut off the monitor on the Displayport shifting everything over to my secondary monitor. It causes no problem, but drives me nuts because when I switch back over to DIsplayPort, I have to move my open programs around again. Is there any simple way to make this stop? If I don't use DisplayPort, and instead use HDMI/DVI combination, the behavior described does not happen. I'm guessing that is just the way it is, but I'm hoping there is an easy way to make it stop.

I need support, I'm getting CRAZY!

I bought an screen 27" to connect via HDMI to my laptop, I tried in the store and the display worked straight ahead just connecting the HDMI.
They sent me a few days later a brand new one, and for my surprise it doesn't work.

I know that my laptop works perfectly fine, I connect it regularly to the TV, using the same cable, and the screen works with other computers.

I found in Toshiba's website an update for display drivers, Intel (R) HD Graphics.
Right after the installation of this drivers the screen works!

I can see the duplicate of the image, no issue, but then, I have to restart the computer to save the changes.

Upon the restart, the image isn't seen any more, Intel Graphics doesn't recognize any other output, the screen shows a clear message that there's not HDMI signal coming.

if I reinstall the drivers, the screen comes to life again, only delaying the restart action I get it to work for a while. In the last try I made it didn't last longer than 15' about.

I've also looked into the website of Phillips (brand of the screen), found a pack to update the screen drivers for Windows 8. But my system answers that is all up to date...

What happens if you use the FN + F4 (or only F4) key combination?
Does it switches between the internal and external display?

The FN + F4 changes the active display device. To use a simultaneous mode, you must set the resolution of the internal display panel to match the resolution of the external display device.

Hey guys, hope your all well.So recently I got an extra display to plug into my hp envy 750-129ns so I can use an extended display. The problem is that the only 2 hdmi ports avalible are the ones located at the bottom, I think where the sound things are, and they don't do anything when I plug my display hdmi into them. My video card has only one hdmi port, and the other 3 are just DisplayPorts not hdmi. The screen and cable work fine as when I plug it into this it works. The problem is I need another port to plug my other display into.Is their any reason why these 2 extra hdmi ports are not working? The has a little plastic protector cap plugged into them. Are they just optional extensions that I'd have to get installed, Or am I missing some drivers?Thanks for any help,Alex

Ok a few days ago port forwarding just stopped working, with the exception of a couple ports (the remote desktop port and a netBIOS port, and possibly a couple others).

The first thing I did was check that it was set up correctly, and it is. Then I checked both firewalls (router and windows), and both were off (as is normal for me).

After that I tried DMZ and Static NAT, both failed. The two exceptions I mentioned above would still work, but nothing else.

I updated my router's firmware - nothing.

I've tried disabling my antivirus, still nothing.

Then I turned the firewall on the router on, nothing, the windows firewall... and I got something! With the windows firewall on, ports time out. However if I add a port to the windows firewall exception list that port will say its closed...

Windows Firewall + Block port = Time out
Windows Firewall + Allow port = Closed

Now how does that make any sense???

So it seems to me the problem must be somewhere in Windows... but I can't think of anything... I have no other firewall installed, antivirus hasn't blocked ports before (and disabling it doesn't do anything anyways)... any ideas?

BTW, just before this happened, I had Apache installed and was doing some testing with it. But since then I've uninstalled it. But thats the only significant thing that happened before everything got blocked. Also my router is a Westell Versalink 327w (came free with DSL lol). Any ideas at all will be apreciated.

A:Port forwarding suddenly stopped

Is it possible that your ISP is blocking the ports on which you want to forward? Some ISPs block 80 and 21.

I have a video card and display both with HDMI and Display Port ability.
At the present time I'm using HDMI to HDMI.

1. Can I use HDMI and Display Port using 2 cables at the same time on the same screen and is it a advantage or disadvantage?
Please explain.

2. If I just use Display Port will it work better that just HDMI?

I don't have a Display Port to Display Port cable at this time.
I will buy one if it will make things better.

I'm not having a problem at this time. I'm just trying to get the most out of my hardware.

Please explain.

1 monitor 1 cable

since DP and HDMI are both digital, I guess there is no advantage either way (unlike analog vs digital).

2 outputs usually means dual monitor support, although you'd have to check the manual. Dual screens is the best upgrade I've ever made, esp for my C4D work - also good for watching TV whilst surfing !

BTW although I mainly use DVI, I had to buy a HDMI lead recently to test some gear. I was surprised to see a note in the package to the effect 'warning do not hot swap this lead - power down all equipment before connecting'. Apparently there's some kinda live detecting pin that can cause probs when hot plugging.

Just purchased a new Mobo (Asus P8Z77-V Deluxe). Haven't bought the CPU. I am waithing on the new 22nm models. After taking a close look at the display outputs on the mobo I have a choice of HDMI or Display Port. None of my existing monitors have ports for that. Soooo I guess I get a new display.

What should I be looking at as far as cables and the choice between HDMI or Display Port. I am not familiar with either one. Also I am assuming the cabling is different for the two ports.

A:Display Port or HDMI

You can find adapters to allow you to use either with DVI. If your current monitor needs replacing anyway, an HDMI-native model will be cheaper than the DP version.

It can get more complicated if you have plans for multiple monitors down the road.

A:Solved: HDMI To Display Port

Afraid adapters aren't going to work.
SVGA outputs an analog signal.
HDMI is digital.
You would need a signal converter and those aren't very cheap.

Hi all, I have an Acer S7 392 ultrabook, with a water damaged HDMI port. I have successfully used the supplied display port -> VGA adaptor to connect a monitor, but I need to be using HDMI. Is it possible to get a display port -> HDMI adaptor for this ultrabook? Thanks in advance
