HDMI output not working to my primary monitor

Q: HDMI output not working to my primary monitor

I have Win7 ultimate, 2xNvidia 480GTX running in SLI and an ASUS VE278 monitor. It works fine using DVI but when I connect the monitor to the gc with the HDMI cable and switch the monitor to HDMI mode I get the Windows background, but no mouse pointer or anything to work with. If I try and boot the PC with just the HDMI cable attached the monitor says it can't find an input signal. Does anyone know what the problem here might be?

Monitor is plugged in vga. Toshiba tv us plugged in hdmi. When I turn my computer on it thinks the tv is the vga monitor. If I unplug the tv and have just the monitor it recognises it but if I then plug in my TV. It then switches to that screen and won't return to the monitor even if I unplug my tv. It won't play sound through my tv or recognise it as one. I can't use windows and P as it does nothing. I want the monitor to be primary and tv as secondary with sound. Help me please

Hello,
I have been searching all over for the following problem:

I have a normal dekstop-pc setup with a 24" monitor hooked up to the graphics card with a DVI cable.

To be able to watch a movie on a bigger screen, I hooked up a standard 40" TV to the graphics card via the HDMI cable.

I then Duplicate the screen and play the movie on the PC (they are in the same room). When I do other work on the PC, I turn the TV off.

For me this works fine, the problem however is this:
Windows 10 now sees the HDMI-TV as the FIRST monitor, and my desktop as the SECOND.
(I didnt realize this for a long time until I played a game recently and the screen kept flashing and I was having all kinds of problems where the game just wouldnt run right, which was solved when I pulled out the HDMI cable.)

So, how can I tell Windows to set my Desktop monitor as the Primary and the TV as the secondary, and leave it that way without having to switch settings when gaming or watching a movie.

Thanks for your help,

Hi,

So eagerly i tought to buy this cool looking laptop for a huge $2000 i needed it to output to a hdmi monitor ot TV so sometimes i could see movies as well, now i had to buy the special DA200 dell adaptor and in the past 3 weeks it`s been a complete nightmare, i WAS NEVER ABLE to make it work permanently. The chat support was no help at all usually simply resuming to try and replace the part but i do think the part is good and i didn't feel like waiting 2 weeks for it to ship from china.

The ethernet and usb work on the DA200 adaptor , EXCEPT HDMI.  SOMETIMES it would work briefly until next restart, i had tried everything ever available on the internet. The laptop is running Windows 10 (as it`s restricted to that version, i tried to install other versions with lots of issues and compatibility issues) so  i have installed reinstalled and installed different versions of the video driver for all possible windowses and none worked. what did work was very brief until next restart and that usually happened when i had a fresh windows install, after the first restart i will get a non working hdmi again.  

I have tried several hdmi cables so i know it`s not the hdmi cable or the tv ot the monitor. and nobody seems to be able to help!!

Hello,My monitor on my laptop will not display anything except when I turn it on where I have green lines down the right half of the screen but everything else is black. This last about 30 seconds and then my monitor remains black. I have attempted replacing the monitor however that one stays black and has no display either. Regardless of the screen I have attatched, I have no problems connecting it to my TV via HDMI and using it that way graphics wise. Upon closely inspecting the motherboard I have not seen any cracks or any other damage. Any insight on this problem would be very appreciated.

Since TB16 is so way out of my budget, I decided to do the following setup to get a triple monitor setup on my XPS 15 9560.

a) HDMI output to one 1080p monitor
b) Thunderbolt3 to 2xDisplayport Adapter, then connect one 1080p monitor and 1024p monitor

Thunderbolt3 to displayport adapter only worked with Active HDMI to Displayport converter. But, if I connect all monitors at the same time, only two monitors will show up. So, either outputs through HDMI and one of the thunderbolt3 port, or two of the thunderbolt3 ports.
Is there a way to get around settings to enable 3 external displays at the same time without purchasing TB16?

My laptop crashed when removing the HDMI cable... totally dead... had to pull the battery to get it restarted. Now unfortunately the HDMI output is no longer recognizing the TV unless there is a second VGA monitor connected. Does this sound like a hardware issue?

A:HDMI output not working.

Sure sounds like it.

But first, go to Control Panel > Display > Change Display Settings > and click the Detect button with the HDMI connected to the TV.

I have been operating under the assumption that you should never "hot plug" HDMI connections. Turn off the laptop and TV, connect the cable, then turn them on.

Hi everybody,I have an incomprensible problem with my X270. I use an external monitor in 4K with an HDMI cable (my dock don't have displayport). But the 4K output isn't working all the time. When I turn on the computer sometimes I only have 1080p resolution and I can't change it (for 4K, I can for less like 720p). But sometimes, it is working fine. Even if I don't change anything. For exemple, I do an update, restart my computer and after it, without changing anything, I only obtain 1080p. If I restart 3 hours later, I can have 4K. (I am on Windows 10)But, I also have Debian on my computer but I prefer W10 when I use my 4K monitor because Debian isn't perfect with 4K. But on Debian, the computer can offer 4K on the monitor everytimes. There is no problem to detect 4K on Debian. So I don't understand why it is not working with W10.Any of you have the same problem or a solution?

Hello everyone,

My apologies if there were similar threads about this, as I just made an account and didn't get to check them up. Although I did search google and there were few cases with people that were using NVIDIA, since I'm not using it I would like to know how to solve this.

Your laptop might be outputting a higher resolution than the TV can display. You mentioned it was a DLP TV so its probably only 720p, so if you laptop is outputting 1080p it might not work.

For some reason, when I tried to connect my laptop to my HDTV with the HDMI cable today, it did not work. Normally, as soon as I plug the cable into my laptop, my display immediately switches to the TV, but now my computer is not even detecting an additional display, or the HDMI plug. It was even working fine yesterday, but today, nothing. I have tried uninstalling and re-installing the graphics processor, setting the computer to second screen only, using a different cable, different TV port, all the usual stuff, but for some reason my laptop just will not detect the HDMI cable.

Here's the basic information for my computer:

The computer is an HP Pavilion g6 laptop. Thanks!

Hi,

I have an HP dv6500 laptop with NVIDIA GeForce 8400M GS (HDMI output). I just bought a philips 8404 LCD TV.
When I try to connect the laptop to the LCD, nothing happens. I can't get any video displayed on the TV.
I know that both the cable and the TV HDMI port are fine beacuse when connected to the XBOX they work without a problem.
I can see the TV on the NVIDIA control panel, it is recognized as "Philips FTV", but when set to dual display nothing happens, and when set to use the philips tv only, the laptop screen goes black (as it should), but nothing on the TV.

I have the TV for few days now, weird thing is that one time (and one time only) I did manage to see the computer on the TV via the HDMI cable. I didn't do anything special - just clicked Fn F4 and it was there. but it only worked one time and I can't get it to work again (but at least I know the HDMI port on the laptop is also fine). When I connect the cable to the TV I do hear the "windows new item detected" sound on the computer, so there is a connection but no picture at all.

I tried re-installing the NVIDIA drivers but nothing helps.
Any help or suggestion would be appreciated...I waited for an HDTV for a long time and now I finally have it but without the PC link it's rather futile

I have a strange feeling that re-installing windows7 would solve it (as it does for most things ), but I'm trying to avoid this annoying lengthy process...

Cheers,

Recently, this stopped working (I had not installed anything new or updated the computer). The HDMI cable is definitely still good. My laptop could not connect with the external display. I tried everything I could think of including making sure the drivers were up to date (they were) and the handy reboot method. Nothing worked until I went into the device manager, right clicked on the graphics card and uninstalled and reinstalled it. Using this method, I got it to connect again for a couple of days, though I had to uninstall and reinstall every time to make it work. This has stopped working now too though. I am at a loss.

Hey!

I have a Portege R705 and for around 2 years I've had a setup with two samsung Syncmaster 2443 displays, one connected by VGA and 1 with a hdmi to dvi cable.

I've never experienced any problems until one of the screens could not detect a signal anymore. Neither monitor can detect the hdmi signal and both detect the VGA.

I have proceeded to purchase a hdmi to dvi adapter and connect the dvi cable that was delivered with the monitor to my screen but without success.

I'm pretty much out of ideas, has anyone experienced something similar or has anyone got any ideas on how to fix it?

Hi guys,
I recently upgraded to Windows 10 from Windows 7 on my HP G60 125CA laptop. I never had this issue with Windows 7, but ever since upgrading to Windows 10, I can no longer use the HDMI port to use an external monitor. The problem is, the computer recognizes the external, as it makes a sound AND shows there's two monitors (the laptop and the external) in the Display Settings, but I get no signal on any monitor I use, no matter what HDMI cord I use. I've tried adjusting the resolution to 1920x1080 for my HDTV and that didn't work. I still get no signal. I have the latest NVIDIA graphics driver. NVIDIA GeForce 82000M G is the video card. I've tried re-installing, completely removing the driver, doing a clean install, installing an older driver and none work. I even tried extending, duplicate, show desktop only on 1, show desktop only on 2, etc.

If you guys could help, I'd greatly appreciate it.

Thanks!

Hey guys I have a ASUS M51vr Notebook Running windows 7,
I have the latest ATI Drivers for my ATI HD3470 mobility
Plus latest Realtek HD drivers.

My problem is when i plug in my hdmi output via my hdmi cable it doesn't make the new device detected sound it would make on vista then allow me to choose to extend or duplicate to the new monitor. When i plug in my hdmi cable in, there is no picture until i reboot the computer then the picture comes. But i still am not able to have audio coming out from the HDMI output. On Vista i would connect the cable and then the new device sound would beep and it will allow me to choose extend options and the sound will work without a problem.. Now i see this is a comman problem and i been doing my head in trying to fix it the past 2 months, i'll post my Computer details and images of the HDMI cable not detected as it is currently connected.

Hello everyone, I purchased a Lenovo Ideapd 110-15ISK laptop about a week back. I am trying to connect it to my Samsung TV for external display using HDMI cable without success. Hot keys are not at all working after connecting the cable and I am therefore not able to give the command. Win+P command is also not helping. I have even tried lowering the screen resolution to 1024x768 but no relief.Please help!

Hi all,
 
For some reason, my HDMI audio output to my television stopped working about two months ago. I finally came across a solution this afternoon to fix it, but as soon as I reset the laptop, it reverted back.
 
First, some specs:
 
Laptop: MSI GT70
OS: Windows 10 x64 Home
Audio Driver: Realtek HD Audio v.6.0.1.7324
 
Seems like I've tried everything I can find on forums. Here's a rundown of everything I've checked:
 
1. Playback Devices -> Show Disabled/Disconnected Devices? Yes
2. Restarted Windows Audio Service? Yes
3. Device Manager -> Sound, Video, and Display Controllers -> Scan for Hardware Changes? Yes. (This was the fix this afternoon, is no longer detecting TV for an audio device after reset)
4. HDMI cable integrity -> verified.
5. Remove and reinstall audio driver? Yes
6. Remove cable from both laptop and TV and re-connect? Yes
7. Remove cable and restart laptop and tv? Yes
8. Repeat above step in various different ways.
9. Verify audio path on TV HDMI port is working? Yes, with a different laptop using same cable.
 
I didn't have this problem for the last two years I've owned the laptop. I've been to sever hotels with different TV's and it's been plug-and-play the entire time - until recently.
 
Like I said before, it worked briefly this afternoon again until I reset the laptop. Now the above steps I used to correct the issue the first time are no longer working. Does anyone else have any ideas?

A:Sound not working, Only have HDMI Sound Output, But no HDMI port in PC

the HDMI sound is most likely off your GPU but that series seems to not have a HDMI port so that is odd. If you can make sure your onboard audio is on in your BIOS and also run the tool on this page so that you can update all your system info for us. System Info - See Your System Specs
