Ext monitor connected to hdmi port on laptop stopped working...

Q: Ext monitor connected to hdmi port on laptop stopped working...

I have been using an HP Z display as an ext monitor, connected to my Pavilion 15 notebook using the hdmi port. Following an update 2 days ago, the monitor no longer receives a signal from the hdmi port. (I know the monitor and cable are ok as they work on another laptop). Any help or suggestions how to resolve this issue will be great!

Hi,

I've recently purchased a Samsung T23A750 monitor and to my disappointment when I try to watch a movie the built in speakers are not functioning. I have a Sony Vaio Z216GX connected via HDMI to the monitor (HDMI-DVI) port. I can definitely see the video, but no audio is playing from the speakers. The built in speakers are not at fault- I did a self-diagnosis of the monitor and the speakers seem to work fine. I also set the monitor as the default for the audio and even when Win 7 says its functioning properly, the speakers still don't work. Conversely, setting the default to my PC speakers work fine. I'm sure its not the HDMI cable- I used the same one to hook my pc to my tv with everything working fine. Any ideas??

I have a Dell Latitude 7280 Laptop with two Dell SE2417HG monitors.
The contrast on the monitor connected via VGA through an adaptor to the USB-C port is fine. The colour  on the Monitor connected via HDMI looks grey instead of black. 
I tried swapping the connections, the result is that the monitor connected via HDMI the colour seems "washed out" while the monitor connected tot he USB-C is fine. It is therefore NOT the cables or the monitor. I did a further test with an USB-C to VGA & HDMI adaptor. Connected both monitors via the USB-C port one via HDMI cable and one via VGA. Contrast on both were the same and sharp!
This would therefore seem to be the solution, however, this configuration (having both monitors connected via USB-C) only allows one monitor to extend the desktop and not both and I need all three screens to work individually.
Id there a way to set the contrast on the HDMI port? - Changing the settings on the monitor does not work!
Thanks

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.

Is there anything blocking the HDMI ports on the computer and the monitor? you may want to clean them with compressed air.

If that doesn't help try connecting the laptop to another monitor or TV via HDMI so you can determine if it is the HDMI on the computer or the monitor.

Hi,

I'm sorry, I'm somewhat technologically impaired. I've been connecting my tv to my laptop via HDMI cable for several years and it's always worked fine. Today when I tried, the screens just turned back. My TV stopped saying no signal as if it recognized the computer, and the computer screen went black as if it were switching to the TV, but neither of them actually worked. I tried to go into my display settings to connect to a projector which I have had to select in the past, but it says no additional display was detected. When I tried to tell it to do it anyway, the laptop screen started turning on and off every few seconds so it was black, then back to my desktop, then black again.

The really wonky part is that when I tried starting up the computer with the HDMI cable already attached, it showed the windows startup and password screens on the TV as if it were working properly--but as soon as it loaded up the desktop it started turning the screen on and off again until I disconnected the HDMI.

I haven't changed any settings on my computer recently--the only new thing I've installed are some games off Steam. Something crazy's going on with my computer that has never happened before, could someone please help?

I have read a lot of posts on Microsoft forums and this seems to be a very common problem without a straightforward solution. I'm not brave enough to roll back updates, uninstall display drivers or fiddle with graphics cards as is suggested by various forum participants.

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.

Hi,

I currently want to connect a 2nd monitor to my computer. My graphics card has one VGA output, which is what my main monitor is connected to, and an HDMI output too.

The other monitor I have only has a VGA input, I'm wondering if there's a cable or converter I can get so that I can connect my 2nd VGA monitor to the HDMI output?

Thanks

A:VGA monitor, but HDMI port

I think,as your 2nd monitor is not hdmi compatable then your hdmi out form your computer may not give hi def capabilities.
You can get a converter transcoder here http://www.amazon.co.uk/HDfury-1080P-HDMI-Converter-Transcoder/dp/B000SOPWS8 that might do the trick. Could be right for your situation.

Hello, I am weighing up my options between purchasing an Ideapad 500s or a Thinkpad L460. I do a bit of video editing, and when I'm doing that kind of work I want to hook the laptop up to a 4k screen, (the extra pixels allow a much more efficient workflow). To connect to a 4k monitor at 60Hz I have read that I need a DisplayPort output (which I note that the 500s does not have), or an HDMI 2.0. I suspect that the Ideapad 500s does not have an HDMI 2.0 output, but I would be happy to be contradicted. Could someone please confirm this one way or ther other? Preferably if you could point me to some official documentation about the product which answers the question that would be great! If it does have an HDMI 2.0, I wonder if anyone has any idea how the nVidia chip would handle the 4k screen. I wouldn't be gaming or even doing and 3d modelling or rendering - just some HD video editing - so I expect it would be fine? Many thanks,Tom

Hello, I built my new computer about a week ago and was running it off a single 19" Tevion TV while I waited for the HDMI cables to arrive so I could setup my second monitor.

They arrived yesterday and when I plugged in my 32" JVC LT-32DA30J there was overscanning and the bluriness. I fixed the overscanning in the TV's menu and now the size is correct but even at native resolution, the JVC monitor is still quite blurry and is a strain to look at and concentrate on.

Plugging the HDMI cable into my Tevion monitor made that go blurry as well so it could be the HDMI cable or the motherboard ports (when I first got the PC, the VGA port had the same problem but once updated it looked normal)

Does anyone know of a fix to this ? Or can at least suggest what part is going wrong so I can try and fix it ?

What I have tried:
Changing the resolution - all the different resolutions all show the same blurriness
Changing the refresh rate - problem persists through all refresh rates
Changing monitor settings - As above, changing these settings didn't help with anything

Any help is very appreciated , I've been trying to fix this problem for most of yesterday

A:when connected to lg monitor with hdmi cable i get no sound

The issue here is that HDMI cables, as the name indicates, carry audio signals to the monitor. Therefore if the monitor has no built in speakers then there will be no sound. If you have external speakers you can plug them into the audio out slot on the back of the monitor and the problem will be solved. However, if the screen does have built in speakers you need to go Control Panel>Hardware and Sound>Manage Audio Devices and set either your headphone jack or the screen to be the default device. And then you ca pick which device the sound will play from. Either yourlaptop speakers or whateer speakers are plugged into the laptop or the Monitor and whatever speakers are plugged into the monitor

Hi

I have an i5-based DG67BL intel motherboard computer that has a DVI and HDMI ports with one DVI monitor connected to the DVI port.

I added an GeFORCE 210 graphics card to it that has a VGA and a DVI ports and connected additional two monitors to it.

So far computer is working fine with three monitors configured in windows as extended desktop.

This motherboard has just one PCIeX16 slot. It has 2 PCIeX1 and a PCI slot that are vacant.

I need to connect yet another DVI monitor. I took a HDMI<->DVI cable, connected it to the onboard HDMI port. the monitor was not detected.

I tried various combinations of monitors and bios settings in vain. Under no circumstances the HDMI port drove the DVI monitor.

The cable is working fine elsewhere.

What did I do wrong ? Is there something I need to buy/replace for this to work ?

Thanks !

A:How to connect additional DVI monitor to HDMI port

you 'need' to connect a 4th monitor? I recommend getting graphics card(s) to support your endeaver, but up to you.

Why don't you get a dvi to vga or maybe its a vga to dvi cord and connect the dvi monitor to the graphics card vga port?

Does it have to go into the HDMI port? HDMI carries sound as well as the video signal, dvi only carries video, and vga carries a lesser quality video

I have Lenovo B540 All-In-One (Windows 8) whose monitor is cracked and the screen is black. I'm trying to still use the computer or at least access the hard drive by attaching a second monitor through the HDMI Out connect slot in the back. So I purchased the "DVI-D to HDMI (or vice versa)" cable (Dynex brand) for $40 from BestBuy and made the connection to my DVI monitor.

Well, Lenovo turns on but is not recognizing the second monitor! Should it automatically recognize the second monitor or are there some steps involved like pressing down on certain function keys (like you would in laptops)? I've perused Lenovo's hardware support manual but they don't explain proper steps.

Does anyone know what the proper steps are when the original monitor is not working? I know for sure the computer itself is working; it's making all the right Windows start-up noise. No, the computer is not passworded so it should go in straight.

Would it be easier to connect to the TV via HDMI? Would I then need HDMI cables?

Thanks everyone for any suggestions you might have to offer.

Please ensure you have done both of these and then post back; it would also be helpful if we knew your system specifications which you can fill in under 'User CP'.

Hello Community-  I recently purchased a Lenovo X1 Carbon along with a Lenovo Thunderbolt 3 and two monitors. I have tested out the monitors individually with another computer, and they work fine.  Currently, I have one monitor connected via VGA to the Thunderbolt dock, and I have 1 monitor connected via HDMI to the Thunderbolt dock, which is connected to my Carbon x1. I only have connectivity with the VGA connected monitor, and do not have connectivity with the HDMI connected monitor, although I hear the system "connection sound" when I plug in the HDMI cord.  What is the issue here?  My goal is to have two monitors connected via Lenovo Thunderbolt 3 docking station to my X1 Carbon laptop. Thank you

I have an HP ZR22w monitor with three inputs: VGA, DVI, and DisplayPort. I want to hook up a computer to the DisplayPort, but my video card id HDMI out. All the cables are sold as DisplayPort source out to HDmi monitor in. Are these cables reversible?
Can you recommend the right way to hook this up? Is there a cable that exists for this situation? Do I need a combination cable/adapter?
Thanks!

Hi All I am in need of assistance.
I have a new Dell 17r inspiron laptop that only has hdmi output. 
I have projectors that connect with VGA port only. 
I purchased hdmi to vga adapters and when I connect to the laptop the image will jump from the laptop to the projector and jump back to the laptop and it will continue to do this over and over. 
There are no error messages. on either. These are working projectors. These are new hdmi/vga adapters.
I have tried to change resolution to lower settings and I have tried to lower refresh rates. The projector can support all of what resolutions the laptop has for settings thus the image does show for a second on the projector. These are smartboard/projector 600 series. I have also tried swapping our the adapters that didn't work either. I have also tried making the resolution settings shutting down laptop , connect the hdmi/vga adapter and turn the laptop back on and the issue is still the same. I can't find any posts/forums on this issue to date. 

Thanks,

C0v3r,
I am not aware of any issues with the 17r using external monitors.   I would suggest trying to narrow down the problem and go from there.   I certainly understand that you may not have all the devices present but if you do I would try to verify if this is problem with HDMI on the notebook, a problem with the adapters, or the monitors.
Basic steps, try running the notebook under power saving or high performance in the Nvidia control panel. The system is  an optimus and it would be interesting to find if the problem only occurs with the integrated Intel GPU (power saving) or the Nvidia GPU (high performance).  If you aren't familiar with configuring Optimus the following document may help.
Uninstall and reinstall video drivers.  Download the latest Intel and Nvidia video drivers for your model of notebook from support.dell.com. Download the drivers and save them to the desktop, please don't install them yet.  Uninstall the Intel and Nvidia driver and software from the system and reboot.  Now install the drivers, with the Intel driver first, followed by the Nvidia driver.
If possible connect the notebook to a HDMI monitor, something that doesn't require the use of any adapters and see if the problem continues.  Verify if the HDMI ports is working at all on the notebook.
If it looks like video is working fine on the notebook, and HDMI works well. Test the HDMI to VGA adapters.  If possible try them on ... Read more
