Let's check device manager and see what is listed under display adapters. We need to be sure the correct video driver is installed. Also please describe your setup. HDMI cable from laptop to what? Monitor? TV? Have you tried the Windows key on the keyboad plus the p key to see if you can get it displaying on the external screen?

Hi guys this is my first post as im at a loss of what to do .
Recently my old monitor stopped working, it was using a VGA cable, but the cable is not the problem, my PC is. I bought a new monitor which requires HDMI, however the port on my PC will not respond to the cord, meaning I have no monitor :/ or anyway to troubleshoot. The only thing I can think of would be to buy a USB to HDMI adapter? But even then I would need a monitor to install the device surely. I would usually take it to the shop, but with lockdown I am lost and without a PC for the forseeable future, help would be appretiated!
 

A:Faulty HDMI Port- 'No signal'

Hi Warro, and welcome to TSG.

I don't think anyone here can give you much help without knowing:

1: Name of the manufacturer and exact model number of your computer and/or the motherboard.

2: Name of the manufacturer and exact model number of any video controller expansion card (the card itself, not the manufacturer and model number of the graphics IC) plugged into the motherboard.

3: The operating system running the PC.

I want to use 2 displays using HDMI, but the only problem is that when I plug in my HDMI to my TV through the motherboard, it does not work. I know some do not support it which is why I am coming here. My mother board and graphics card are in my account so look there for the details on my computer. Thank you

A:Can I use my motherboard HDMI port as well as my graphics card HDMI?

I've seen a number of computers where the addition of an Add-in Video card automatically disabled the onboard adapter. The only thing that worked to restore the onboard adapter was to remove that Add-in card. You may want to consider getting a different Add-in card that has 2 HDMI ports. Or if your motherboard has 2 PCIe X16 slots get a 2nd matching card.

Hello all, i recently bought a 1070 gtx but i am still using my old monitor until i can afford a new one.

The 1070 has no VGA slot so i had to buy one of those HDMI to VGA adaptors in order to connect it to my current monitor, however i get no image at all while i connect it.

This is the adaptor : https://s13.postimg.org/8iqt3l6ef/00054569abx.jpg Hama HDMI to VGA converter.

I have an HP Desktop Envy All in One. I used an HDMI cable to connect my PC and my Samsung UHD TV so I could use my TV as a 2nd Monitor. I have verified the cable is fine along with the HDMI ports on the TV. When I use the "Source" button on the remote and select HDMI port 2, it tells me there is NO signal or it's not strong enough.

Hey,

When I connect my PC to my TV Via HDMI Cable, my TV does not receive a signal. When I check in Control panel>Display>Resolution, My TV hasn't even been detected. My TV is an LG 50", Card is a GTX580, and my OS is Win7.

Also, when I connect my laptop to my TV via HDMI (Also on Win7), It is instantly recognised and automatically displays, so it has to be an issue with the PC itself.

Spent a while on google trying to find a solution, but unfortunately I couldn't find one. Thanks for any help on this.

A:PC To TV via HDMI. No signal.

Hi there
What do you get on your MAIN PC when you press the windows + P key. It should be settable to display on 2nd screen only.

It should allow you to switch monitors. The monitor probably isn't being recognized since your PC is set to display on your main screen only (by default).

Ensure the TV is switched on and the input set for HDMI. You'll probably have to change the resolution - laptops seem to work fine --desk tops seem to be different -- probably because of the difference in the graphics cards - especially built in ones.

Laptops recognize when a monitor is plugged in -- this isn't always the case with Desktop PC's so try it with the WIN +P key with the TV switched on of course and the HDMI cable plugged in.

If you DO get it to work don't forget to re-set the screen back to PC display before disconnecting or at the next boot if you don't have the TV plugged in you'll end up with a nice blank screen.

Cheers

I have a new 40" LCD Dynex TV with HDMI connections and a one year old Acer computer with Windows 7, which has an HDMI terminal. I have tried to connect the two, using all kinds of combinations of plugging in the cable before and after the computer starts or the TV is turned on etc. I have gone into the display on the computer and see that the computer recognizes the TV as a device and it also indicates that it is working properly, but I get absolutely no signal at the TV. I have tried different resolutions and different recovery rates, but to no avail. I know that the connections are good and that the TV input mode is the correct one.
I see in the "display" function of the control panel that two monitors are shown - one for the TV and one for my computer monitor.

So, I just finished building my first ever custom PC. At first I couldn?t even get it to turn on, but that?s not my current issue; after finally getting my computer to turn on, now it doesn?t even display anything on my monitor. In fact, it?s worse than displaying nothing; it shows the monitor?s blue screen with the ?HDMI No Signal? message, as if my computer isn?t even hooked up to the monitor. I use this same HDMI cable and monitor for my Xbox One, so I know that those aren?t the issue. The problem must be somewhere in the computer itself, but everything seems to be running fine.

Just to clarify; this is a fully custom built PC and this is my first time attempting to boot it up. I haven?t even had the chance to try to install my Win10 OS because I can?t get my monitor to present the Startup BIOS.

I posted this issue and a follow up on another forum; however, that forum seems to be a little on the dead side, so I decided to ask you experts. For that reason, I am splitting this into the two days I have spent trying to figure this out (to no avail).

Day 1:

So basically, I've been connected up to this 37" Emprex HDTV for a few days (nothing great... use the nice Samsung for the PS3), with no problems... well, ok, one problem. While fine at first, yesterday the computer decided to stop picking up the HDMI audio, with Windows 7 listing it as "unplugged." I tried uninstalling, reinstalling, and rolling back the drivers as well as installing new ones (Realtek... not sure if it had anything to do with anything, but it was worth a shot) to no avail. That was only the start of the problems however.

This morning, everything (except for the audio, of course) was peachy. A few hours ago, however, the TV decided to just stop reading the HDMI signal all together. No video, no picture, no nothing. All I get is a blue screen that says "No signal." I've tried numerous cables, unplugged and replugged countless times, uninstalled and reinstalled all the drivers, and nothing. VGA works though, so that's what I'm using now. By the way, the problem occured after I had moved the TV to a new spot, so it's n... Read more

I have just built a PC with the ASUS M4A88T-M motherboard which has Radeon HD 4250 on board graphics. OS is Windows 7 Pro.

I have installed all the motherboard/graphics drivers that were supplied on the CD, but I cannot get any video or audio output from the HDMI slot.

I know that there are sometimes issues getting the audio through the HDMI cable but there is no video signal either. The VGS & DVI slots are fine, and also using a DVI-HDMI cable works, but then I have to use separate audio cables.

Do you have to enable HDMI within Windows anywhere ?

However, there is no communication, the Dell doesn't see the Canon at all. On the previous desktop I used to do it through the FireWire port, but the Dell doesn't have it.
I enabled Intel multiple display in BIOS, as advised on this forum some time ago, but it didn't help.

Hi

I've just recently had to rebuild my HTPC with a newer version of Windows 7. I have been using an ATi HD5450 card in my setup for over a year now with no problems.

However, with this new build I've put on, I am now not getting any signal to my receiver from my HTPC. However, as soon as I turn on my TV, I get a signal to the receiver!! So I can get audio but always have to have the TV on, which is not how I remember it working before.

I am no nearer to finding out why all of a sudden there is no signal from my PC to receiver. I have carried out a few tests that Yamaha have advised me to as I thought the issue was with the receiver but it looks like a problem with the Windows 7 and codecs.

I've just checked and I am running the latest drivers for my card as well.

Hope someone can help! Thanks

I bought a new HDMI cable yesterday, hooked it up to my laptop and TV and it worked just as expected. I unplugged the cable went away a few hours and when I came back to use it again and the TV was receiving no signal, Black screen with no sound. The laptop recognises the TV and says the connection is working properly but the TV shows nothing. The cable works between my Ipad and TV so it definitely looks like a setting issue on the laptop which is strange as I haven't changed anything manually between it working and then not. The TV is on the correct input and I have set the laptop to duplicate on a second screen. Tried a few things like changing the resolution and refresh rate but no luck.

Hi all,

I am trying to use my Laptop with an ACER 272HUL Monitor via HDMI cable.

Situation:
Whenever I plug in the HDMI cable, the Monitor Model (Acer K272HUL) and the correct max resolution (2560x1440) is being shown on screen of the Laptop (Screen resolution window).
Also, when selectimng the HDMI port I use on the monitor, the monitor does NOT say "no cable connected" which it does at all the other ports. So, seems that the principle connection between the Laptop and the Monitor works, but no signal is sent ... ???
After a little while, the monitor also says "No signal".
Now, I found on the web that the max. resolution of that monitor on HDMI seems to be 1920 x 1080 @60 Hertz, so I changed the resolution to that values but with no luck. Also reducing the repeat rate to 50Hz (by going to "advanced" and select it from the "mode" Button) does not help - monitor stays black.

Could be hardware damage. Vacuums create static electricity. Static destroys electronics.

Test with a different monitor to verify the computer or monitor is faulty. Or test that monitor on a different computer.

I have recently hooked up two Samsung Syncmaster 2243s to my HP Compaq laptop at work (waiting on an email for the specific model for the Compaq and Nvidia Quadro video card). Unfortunately, the second monitor says "Check Signal Cable" and will not display anything. Here's how I have it set up:

The first monitor is hooked up to the laptop on the VGA port and works fine. I have used extended display with my laptop screen and Syncmaster with no trouble. I hooked up the second monitor to the HDMI port in my laptop with a DVI-HDMI cable. At no point (eg. when restarting) does the monitor show anything but "Check Signal Cable".

I have updated my drivers (windows and Nvidia) and tried removing my display adapter and restarting, forcing the computer to reinstall the drivers. I have rebooted with the second monitor attached and unatatched with no luck.

The key point is that the computer recognizes the second monitor (with the Nvidia control panel I can turn off the laptop screen and set both monitors as my extended display - second monitor still says no signal although the first monitor, which works, behaves as if it were part of an extended monitor). Further, the second monitor works normally, as it was used on a previous laptop via VGA. What could cause the "no signal cable"? I did buy a second DVI-HDMI cable with the same result. Any help would be most appreciated.
 

A:Second monitor HDMI no signal

typically, dual monitors is not done with VGA, or if so, is implemented using a 'Y' cable.

A video card built to support dual video out is usually DVI with Y or two DVI ports on the card.

Issue:
I've tried 2 TVs (Samsung HL67A750A1 and LNT2653HX) and they both give the same 'No Signal' error. For 8 months this setup has worked without an issue with both of these TVs.

The original issue started with the ATI 4650. The PC would still display without issue, but it would randomly freeze and then a few days later the motherboard started giving a diagnostic error code that the video RAM check during POST failed and the computer would no longer boot.

I installed an ATI 4870 I had and the computer booted fine and no more lockups. I was glad I finally figured out the issue. But then the next day the LNT2653HX LCD said 'No Signal' when turned on. A reboot/reconnect cable/re-seat video card, etc wouldn't help. I connected the PC to the HL67A750A1 and received the same error.

Tests:
Both TVs will work fine with another PC and XBox 360. I installed the 4870 in the other working PC and immediately received the 'No Signal' error. I placed my 5870 back in the working PC and while it wouldn't show POST, it did display once Windows 7 booted (interestingly when I connect through my Denon Receiver, the PC will show POST on the HL67A750A1 - just not when directly connected).

The bad PC with the 4870 will boot to Windows and I can even connect to it through RealVNC and gain access to the file shares. When looking at the display properties, it only detects a VGA connection (the RealVNC I assume). I installed Powerstrip and the EDID information it is pulling from the registry is... Read more

A:HDMI No Signal Error

I'm going to tell you that you may need to check your PSU, I wonder if it's putting out the proper power as this sounds likely that it is not.

I'm trying to connect my pc to tv to watch a movie but it keeps giving me the no signal. Please help this computer illiterate girl out. ughhhhhhh!!
 

A:hdmi cable no signal, help please?

Desktop computer or laptop?

Start with both powered off, connect the cable, power on the TV and then power on the computer.

If it's a laptop, you may need to change the output. This is usually done with the FN keys ( FN + F6 I believe) which will cycle through the video outputs (ie: laptop screen, video output, both)

I just bought a new asus monitor 2 weeks ago. everything was fine until yesterday. The monitor knows when you turn on a computer hooked up to it and turns on by itself. So yesterday when i tried rebooting my computer it said "dvi no signal" i tried to to change the input again to dvi and the buttons did not respond and i couldn't event turn off my monitor so i unplugged the power cable and plugged back again and this time it did recognize it. It also happens when i'm using my other computer with the HDMI cable! both cables are hooked up to the monitor but i don't use both computers at the same time! can anyone help me fix this issue? thanks!!!

Hey there @jim1200, Welcome to the HP Support Forums! It is a great place to find the help you need, from other users, HP experts and other support personnel. I understand that you are having trouble with connecting a display to your computer and you are getting no signal. I am happy to help with this. Does your computer have a discrete graphics card installed? If so and if you are trying to use the two HDMI ports on the back of the motherboard of the computer instead of an HDMI port on that video card, then that is the issue. If a video card is installed, the integrated graphics adapter is disabled. Try using the HDMI port on the back of the video card itself. If this is not the case let me know, but if it does resolve your issue, please mark this post as a solution. Kudos would also be appreciated.
