HP envy 23 HDMI stopped working

Q: HP envy 23 HDMI stopped working

I've been running my xbox through this PC for months now and I havent had any problems, although I do need to bring up HP My Display in order for the hdmi to work correctly. I tried to connect my xbox one to the computer as usual last night but this time it said 'no signal'. I have checked to see if other hdmi cables would work (they do not) and I have tried the hdmi cable usually used for the PC on the TV and my xbox connects fine. I don't know of any recent update that may have caused something to go wrong, I can't get it to work.

Hi, I just got a new HP Envy x 360 in July 2016 and a new HP monitor 27es Display in mid-August.  It was connecting to the monitor by using HDMI fine till last week.  From a week ago (around Labor day), it stopped recognizing the monitor.I have an old HP laptop, and it is fine connecting to the the monitor by VGA.  So, it is not the monitor's issue.I remember I did the recommended HP update around the same time.  I am suspecting that update caused the issue with HDMI.  Can anyone help?  Thanks.

HDMI port seems to have stopped working. I usually connect to HP Pavilion 23xi screen but my HP Envy does not now detect it. Tried HP Envy on other screens and it does not detect them either. No idea why it stopped working. Not a computer buff so need simple solution ideally!

I recently bought an HP Envy m7, and I setup an external monitor. I recently had a BIOS update, which I think broke the HDMI port. I connected the port to a projecter, and it still does not get any input through the HDMI. I've tried multiple cables, and none of them work. My monitor I'm using is an LG IPS Flatron monitor. When I plug in the HDMI, it tells me it's not receiving anything to diplay. I've used Windows Key + P to switch it to extend mode, but it doesn't work.

I've had my HP Envy Recline 23-m230 since 2013, and fairly recently (August of 2015), I upgraded to Windows 10. A few days ago, I had tried to connect my Wii U to the computer. The computer does have an HDMI In port and also includes an HDMI In button. I connected them to each other, but when I had pressed the HDMI button, the screen had went black and said "Game Mode, No video signal". For the past few days, I've been trying to find a solution, but no luck. I've switched HDMI cables, uninstalled and updated HP MyDisplay several times, and updated my graphics drivers. I don't want to have to resort to reinstalling Windows or something drastic like that. Please help!

I am having the same problem with the HDMI input on my HP Envy 23 k-009c touchsmart. I know I was using the HDMI prior to the Windows 10 update with my Shaw Direct HD box. The button under the left side was also working to switch between sources. I have tried different drivers by updating and then by going back to an earler version of the driver all without any luck. I was hoping as well not to have to go back to Windows 8 by re formatting and starting over. Hoping to hear about a possible solution to get the HDMI input working.

I received my HP Envy 750-435st Desktop today (ordered from HP) and the HDMI ports did not work out of the box. I tried multiple cables which I verified worked with same monitor (HP Pavilion 27xw)  and another computer. I read on the forum that an older version of BIOS had killed HDMI for a lot of Pavillion users. I used HP Support Assist to update everything in my new computer. Bios updated to F15. HDMI ports still not recognized. I have to connect with an old VGA cable, but need the HDMI to work. Are there other options I can try?

I recently bought the HP Envy Pheonix 860-050na PC and have had issues with the HDMI ports. There appear to be three on the back, however only one works. I have been trying to set up multiple displays, however because of this issue it is not working. Below shows pictures of the ports. The two labeled HDMI ports are the ones that do not work, and the one on its own works without any issue at all. Any assistance with this would be appreciated.Thanks.

You could do a restore to before the update. This ill remove the updates and you can find out if its due to that.

I'd try a second hdmi cable to eliminate the cable. Being that long it may have been damaged.

3rd, update your video drivers.

Hope something easy fixes it.

Hi. A few weeks ago my Z70-80's HDMI port randomly stopped working, no intermittence, no warning, just stopped. It was fine in the morning, working as intended. I then had to run some errands so I shut my laptop down. I came back a few hours later tried to project to second screen but nothing. Thinking it was software and/or driver related I've tried everything from rolling back windows 10 to updating GPU drivers, even the chipset got an update. Can a HDMI port just randomly stop working like that? VGA out is fine, just not the HDMI. If anyone has any ideas I might be able to try.... Thanks all.

I've tried a different HDMI Cable, different TV, updated Windows 10, even joined the insider program in the hope a beta version of windows 10 might fix it. But n luck with anything. Strangely though my tv will detect a hdmi source but displays 'No signal' it's frustrating

A:HDMI has stopped working

Clive235 Hello;Allow me to welcome you to the HP forums!Anytime someone comes here running Win10 and complains about something suddenly not working, I immediately suspect Windows Driver updates.Unfortunately, Win10 automatically forces driver updates on all of us, without our knowledge, and without our permission -- and when this happens, a working PC is suddenly "broken".  This might have happened to you.You need to go into Settings, Update & Security --> Windows Update.Then, choose Advanced Options --> History to see when updates were last applied.  If you see any that include device drivers, those could be the problem. So, if you can, you should see if you can rollback the drivers that are causing the problem.  You do this by going into Device Manager, seeing if the appropriate device is still listed, and if so, trying to rollback the last driver update.And if that fixes the problem, then consider disabling future driver updates using the information in the link:  http://www.tenforums.com/tutorials/48277-driver-updates-windows-update-enable-disable-windows-10-a.h...Good Luck========================================================================I am a volunteer and I do not work for, nor do I represent, HP.---------------------------------------------------------------If my posts helped you, please click the Thumbs-Up symbol on my post to say thanks.If my posts solved your problem please click "Accept As Solution".========================...

My computer's been acting up since yesterday, but nothing really drastic happened until a couple hours ago. Yesterday, my computer was being kind of slow and unresponsive. Website pages weren't loading correctly on Chrome, which was my go-to browser, but were fine on Firefox. I thought this was because I hadn't turned the computer off for a couple days. I just kept putting it on sleep because I had unfinished business, unsaved. However, it got to the point where the unresponsiveness was annoying, so I decided to restart the computer. While restarting, instead of booting back up, it got stuck on the black screen and wasn't doing anything for about 10 minuites, so I just shut it off via the power button and went to bed. (It's done this before, and booted back up with no problem other times.) Today, when I turned the computer on, it booted up fine, but was being really slow and eventually froze. I had to hold down the power button to turn it off. When I turned it back on, I got a "blue screen" that read something like: "your computer has run into a problem and needs to restart. We are collecting some error info. and then it will restart for you." When the error info was collected, the computer restarted, but instead of booting up, I kept getting the blue screen over and over again. It was throwing up two different codes on the screen, one was "WFS_VIOLATION" and the other was "0xc000021a".  Eventually I was able to press F11 to get into the pre-boot sett... Read more

Hi, my computer has stopped showing any signs of connection when plugged into my television. This is a major problem for me because I use my tv as a monitor. It was working perfectly fine, and has been for months, before I moved. Now I set everything up and it won't work. I tried using a different tv and a different hdmi cord to see if that was the issue but it still won't work. The tower wasn't damaged or at risk of being damaged in the move, I was very careful about that, so I'm not sure what's the problem. Thanks for any help you can offer me.

I have a Toshiba Satellite A305-S6898 laptop with Windows Vista (64 bit). For two years, I have watched movies on my TV via the HDMI connection. 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. Any suggestions would be helpful. Thanks.

I searched many threads with similar titles but could not find a usable answer. I hope this post will have better luck.
My PC is connected from the graphics card to a Full HD TV via HDMI. This worked beautifully for 7 months with great video and audio via HDMI. Unfortunately it stopped working. The TV's HDMI ports and the cables work fine with other devices. On the PC I installed a new motherboard and reinstalled Windows. This is all working fine on a friend's display, including the DP connection from the graphics card. Sadly, however, the PC graphics card to TV HDMI connection is still not producing any picture or sound; not even the BIOS screen. The TV recognizes when the cable is attached (no cable vs. no signal messages) but no picture or sound results.

Some specs:
TV: Samsung UE32EH6030W
PC's OS Windows7 Pro - 74bit
Graphics card 1GB MSI Radeon HD 7770
Motherboard Asus H61MC
Processor Intel Pentium G850, Socket 1155, Dual Core, 2.90GHz
 

A:PC to Full HD TV via HDMI Stopped Working

I'm confused, did you replace the motherboard or the graphics card? If you are using a dedicated graphics card the motherboard would have little to nothing to do with outputting HDMI when a dedicated graphics card is installed. Does the second monitor show up in the AMD Catalyst Software? And even though the HDMI cable appears to work with another device, have you tried another HDMI cable?

My Acer ES1-111M HDMI has stopped working. It was working perfect until about a week ago. I believe it's due to a resent Windows 10 update. HDMI doesn't show anywhere in Device Manager. I tried going back to Windows 8.1 , but it didn't help. I reinstalled Windows 10 Clean Install and still no HDMI output. When I plug into my TV my TV detects a HDMI device has been connected but just flashes No Signal. I have tried every driver available including the test drivers from Intel.Almost 2 years ago I bought this to replace my HP laptop that had the exact same problem. When this happened on this Acer notebook I connected my HP to the TV Via the VGA/RGB cable. Now this Is where it gets weird. I got the HP connected and working with the RGB cable and out of curiosity I connected the HDMI cable to the HP and it made that happy noise saying it found the new device and for some reason started working. Since, I have read on the web that when this happens connecting the VGA cable first then the HDMI cable will force the PC to detect a non working port on the HDMI. Or possibly over the 2 years I've had this HP it received an update that restored the HDMI functionality. Problem is I can't test that theory on this ES1-111M because it only has a single HDMI output. I see this problem all over the web and wonder how many people don,t even know there HDMI port is dead because they never use it.

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.

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?

Up until the other day, I've been using my MSI Wind u230 netbook / Radeon HD 3200 to output to my monitor (Acer S243HL - only has 1x DVI and 2x HDMI inputs) and then occasionally swap to a Westinghouse 32" TV.

The other day: I was using my monitor then swapped to the tv, and then returned to my room to connect to the monitor and it just won't work. (To note, I've been using Win key + P to set projector only and to disconnect projector before unplugging the HDMI cable.)

The netbook screen will turn itself off (as if it detects the HDMI-out) but the screen or TV will just show "No signal."

I tried a shorter HDMI cable, tried the other input on the monitor, still nothing. Strangely enough, checking the displays in Catalyst or the Screen Resolution properties, it can detect both the TV and the monitor. There's just no signal coming out.

Even stranger: trying to connect another laptop to the monitor (which used to work) displays "No signal" too.

Now I'm confused. Could it be a software issue? Could I have broken an HDMI port somewhere that somehow broke the other two HDMI cables in turn? Help?

I have been using an external monitor (Samsung PX2370) with my Toshiba laptop (about 2 years old), connected via an HDMI cable. Up until today it has been working fine. This morning the audio stopped working. Now the laptop does not find the external monitor at all when connected via HDMI. I can connect fine with the VGA cable. I have tried a new HDMI cable but it doesn't help.

Any ideas would be most welcome

Regards

A:HDMI connection to second monitor has stopped working

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.

Hey,

Recently, when connecting my desktop PC to my TV over HDMI, all it shows is 'no signal'. It was working fine before then and I know it isn't the TV or the HDMI cable through testing. Has anyone got any ideas what's happened and how to fix this?

P.S: I would write some PC specs but I would need to be able to use a screen for my computer to see them so...

I have Lenovo Z70-80 laptop which had BIOS version ABCN32WW. I've decided to upgrade BIOS to the latest version (ABCN96WW) and the upgrade procedure went without problems. However, as soon as the restarted I've noticed it doesn't output anything on my external monitor connected via HDMI until it boots to Windows after which I get the picture on the monitor. I've tried to downgrade BIOS version to the oldest available version (ABCN73WW) but I still don't get HDMI output. At this point I'd just like to downgrade to the original BIOS version ABCN32WW but I can't find any downloadable file to do so and currently I'm stuck with no HDMI output until laptop gets booted to Windows which is really frustrating. Any help or suggestion would be highly appreciated.

After updating the BIOS to the latest June version, the HDMI output just stopped working. I tried connecting the cable to the display via DisplayPort to HDMI adapter, and it works, so that problem is not in my cable and not in my display. Trying to connect the HDMI to the display and using Picture in Picture I can see that the display doesn't detect any HDMI displays.  Resetting the CMOS doesn't help. Any ideas?

sorry for starting a new thread but i have searched through so many and still not found a fix for my issue

I was watching a movie and sound worked perfectly fell asleep woke up the next morning and no sound through my tv connected via gainward gtx550ti HDMI port it still shows in playback devices and when i test it still shows sound is playing but nothing comes out of the speakers. i have tried every possible thing i can think of to fix it system recovery, update drivers, uninstall and re-installing drivers, using both hdmi cable and tv with a different device and using speakers with built in sound card so im thinking its my graphics card that has a problem but any other suggestions would be greatly appreciated

A:HDMI sound randomly stopped working

The HDMI is generated by the video card. If the HDMI is set as the default audio playback device and there is still no audio, its most likey a problem in the video card.

One thing you haven't tried, reseating the video card. Its a long shot but give it a try. Power off the PC before reseating (unplugging and plugging back in).

So ive encountered a recuring problem with my V110 laptop. The HDMI port on the computer is sometimes not working. Usually it takes a couple of hours each time to get it working again but im getting annoyed that this is a requrring problem. (general things ive done is make sure the HDMI ports on tv works, changed hdmi cable, changed computer ect to verify its a problem with the V110)Generally the HDMI port stops working after either windows updates, or software installs, however this time it did not work to roll back any updates or uninstall any programs. Ive disabeled and re-enabled graphics drivers, updated graphics drivers, rolled back a windows sequrity update that came into play 13th/14th of sep. 2017.Nothing shows up under display adapter in device manager, and ive tried many of the suggestion fixes on different forum posts to no solution.I'm fresh out of ideas. Anyone have any suggestions before i just reinstall windows in hope that no updates will screw over the HDMI port?
