Lenovo P50 - HDMI External Monitor Not Working After Sleep (My Other Laptop of the Same Kind does)

Q: Lenovo P50 - HDMI External Monitor Not Working After Sleep (My Other Laptop of the Same Kind does)

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.

Have you compared the Power Option settings on the two laptops to see if they match as well?Do the two systems share the same monitor, and if not, how is your monitor configured, does it have an option to set the input source to HDMI vs. automatically detecting the source?When in the mode where the screen does not turn back on, what happens if you press the following key combination Windows Key + Shift + Ctrl + B (forces a reset of graphics cards) do you hear a beep and your screen wake up? That key combination sometimes works to wake the monitors, and while not a solution, it may be a work around until you find a permanent one. Best of luck,

Hello, I can't connect my laptop (Asus with nvidia graphic card, windows 10) to an (old 4/3) Lenovo  monitor (model L1700PC) using an HDMI/DVI cable : it does not work (no signal on monitor) :- if I try to connect my laptop to other monitors (4/3 not Lenovo  or recent 16/9 not Lenovo) with the SAME cable and input/output, it works.- if I try to connect an other laptop (Lenovo) to this Lenovo monitor, it works too (always with same cable, output/input). I tried to solve the problem with ASUS support and nvidia support but they didn't find any issue.... :-(The drivers for the graphic card is up to date. Any idea ?Thank you  for your help.

I have a Lenovo G50 running Win8 32bit. I have two external monitors both Asus with VGA ports. I successfully configured one of the monitors to the VGA port. However I have not been able to successfully get my 2nd external monitor connected using the HDMI port. I have a VGA to HDMI adapter for the monitor but it's not working. To rule out any issue with the 2nd monitor, I was able to get it to work by disconnecting the VGA cable from the first monitor and connecting it to the 2nd monitor. But again, no luck using the HDMI port with a VGA to HDMI adapter. So I'm fresh out of ideas. Had anyone been able to resolve this successfully with this setup? And if so, how? Thanks in advance! Leslie

I have a HP Spectre 13 Ultrabook (Model No. F5C93EA#ABU) originally shipped with Windows 8.1 64 bit.About 2 months ago it was updated to Windows 10 64-bit with no great problems (update in place).Recently I observed that the external HDMI port no longer works when trying to connect to a TV. I have since tested many combinations of external monitors and cables together with other laptops and proved the problem is with this laptop, We have updated windows 10 to the latest aniversary update to attempt to fix the problem and have also uninstalled and reinstalled the Intel Gaphics Driver which is currently at version This the latest driver is as posted at the HP website and tends to the be the version that is also automatically installed via windows update.  I notice that actual baseline release date of is August last year. Intel have many later non-OEM versions but this is the latest HP OEM version. I am at a loss on how to fix the problem and have had to resort to a plugabble USB3 to HDMI adapter to provide external monitor support.

Hello Community, I am looking for your assistance regarding a topic with the external display I am currently using. I am running a Windows 10 on my laptop and after an update of the nVidia drivers - I have an issue with the signal going through the HDMI cable. While the External display is plugged in - it is using the Intel Integrated. I have came across a similar topic in here:https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Lenovo-Z50-70-HDMI-not-working-when-connecting-... And I have done almost everything except the "RESTART" option. I have checked the HDMI cable and it is High speed - and yes, I am sure - the issue first appeared when I updated the drivers. Now I have reverted to older version of the drivers but still experience the issue.

I have a lenovo b570e laptop and am running Windows 8.1.

I recently bought a new monitor (ASUS ve248h) to use as a dual monitor along side my own laptop however upon connecting the HDMI cable with the monitor it doesn't appear to work. I have tried updating the drivers and the hdmi port does work while I am connecting to my LG tv using the hdmi port. I have used various cables including the one that connects it to the tv however so far without success.

I am a bit clueless as to why it would work with the tv and not the monitor also my brothers laptop (which has Ubuntu) does successfully connect to the monitor.

Any help would be much appreciated and Thanks in Advanced

Hello, it's me again. First I have to say that I would never buy this laptop again, because of all the other issues befor that, but what can we do now. So, I had to upgrade to Win10, because of all GP at work and security issues, so i've found out that my HDMI port is not working like it should be working. i have it connected to second monitor with VGA cable through HDMI to VGA adapter off course. I tested it with other laptop,it works perfectly, so the signal is going through. I also tried to disable and uninstal both of nvidia and intel graphic drivers. But still my second monitor is not recognized and cannot be identified. what else can we do? Help would be very much appreciated, Miha.

Does HDMI needed to be unplugged and plug back in for it to broadcast a signal from Laptop to an external monitor? Because this seems to be my case at times.

A:Laptop connecting to an external Monitor via HDMI

It shouldn't. Does the problem occur during bootup, or while in use?

Also, if it occurs after letting the PC sleep or hibernation, it could be a hardware or OS/software issue.

I upgraded to Windows 10 last week and everything was smooth.  Today when rebooting my system, the unit no longer can see my external display.  I have tried multiple other displays and none seem to work.  I have the latest video drivers for Win10 from the support site installed but it still doesn't work.  Any thoughts?

I experienced the same - and also inconsistently that the system is going sluggish/lagging heavily. To fix problem with HDMI downgrade to drivers for Win8.1 - it works but hopefully Lenovo will fix this issue with Win10 drivers!? Overall upgrading to Win10 has been a bad experience (regarding the lagging of the system which usually occurs after 20-30 min after logging on). I've tried removing all third-party startup programs (including Lenovos) - but to no help. The frustration is increasing - any tips will be appreciated :-)

There were a lot of very old posts on this topic but no fresh ones, and hardware and software have moved on.  But the problem remains! So I am starting a new thread for a current solution. Trying to connect new ASUS monitor to my HP Envy laptop using Windows 10. I can use an adapter off a USB port into the monitor's VGA input, but I would like to do HDMI to HDMI (Monitor has HDMI input, Computer has only HDMI, no other outputs except USB.) When I try to do this (of course monitor then is set for HDMI input), the computer does not discover the monitor. It also does not see the speakers in the audio settings. What should I do?

Check the device manager under display adapters. Sometimes on a Windows 10 update you get Microsoft Basic which will not activate the HDMI port and you need to get the correct driver for the video. It would also help if we had the full model number or Product Number.

Why do I lose audio after plugging in an HDMI external monitor to the laptop?  When I unplug the HDMI monitor the sound comes back to the laptop.  I have a Inspiron 13 5378.

A:Why do I lose audio after plugging in an HDMI external monitor to the laptop?

Because HDMI is capable of carrying audio, so in case you plugged your system into a TV or receiver, it defaults to sending audio out of the HDMI port.  If you wish to override this, while you have a display connected, go to Control Panel > Sound, right-click your regular speakers in the list, and click the "Set default" button.  You may need to close and relaunch any open applications for them to start using your regular speakers at that point.

Hello all,
    I have a question about my laptop (Dell Latitude 7480). My laptop randomly freezes after starting the laptop. It takes around 1-5 minutes to freeze, and I can't do anything about it. After a while, I found out that if I'm not plugging the laptop to an external monitor through the HDMI cable, it will cause this happen, but if i plugged it in, it works perfectly fine.
    Has anyone facing this issues and fixed it in the past?. This issue is really annoyed me very much because I cannot work without an external monitor.
    My guess is that something happened with my graphic card? Do I need to change the laptop or is there any other way to fix it?

Thank you very much for your answer, very appreciated.

Hello all,

I've set my external monitor as primary because the laptop screen is broken, via Q&A: How do I make an external monitor my laptop's primary display?.

However, when waking from Sleep the primary display is switched to the broken laptop screen instead of the external. If I hit Window+P on my external wireless keyboard, I am able to select the external monitor and then it will come on, most of the time.

Is there a way to set the external monitor as the primary after sleeping? Perhaps a third-party program or registry tweak? I've googled around and searched this forum, but have not had much luck. All drivers are up-to-date

I found this forum post which looks promising, but not sure if the solution proposed is applicable to my case.

Thank you.

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??

Yesterday my new laptop arrived, Windows 7 (64-Bit) pre-installed, I've downloaded all the updates; there are no other issues with this computer.

The only problem I'm having has to do with the external monitor; it's a IBM (6332) E74 monitor. Windows 7 detects and correctly names the external monitor E74, but the monitor just flashes no signal. I also located and downloaded the the IBM E74 drivers .zip file, but Windows 7 , says it is already using the latest drivers and ignores them.

Any suggestions would be great, thanks.

Hi - Using IBM T42 with External Monitor. When booting Win XP Home SP3, both monitors work, then laptop monitor goes blank. External monitor works fine. I have tried everything I can think of - resetting displays, changing ATI Radeon mobility 7500 driver, disconnecting external monitor, Function key combinations, booting in safe mode. Nothing works. But when the laptop boot starts, the laptop monitor works for a few minutes then shuts down. Seems like a switch is not working properly.
Any ideas as to how to solve this problem. And the laptop monitor was working fine until a few days ago, the last time I used it alone, i.e., separate from the external monitor.

Many thanks in advance.

Being that the ibm t42thinkpad is an older model its very possible that the whole screen will need replaced as the ribbon cable, inverters, or backlights might have gone bad.replacing the whole screen might be easier to do than trying to find the individual parts needed.

Hey guys, I'm wondering if any one can assist me with a fresh install of Win 7 Ultimate x64 on my HTPC.The issue is this, the HTPC remains on at all times.
Every power saving feature I can find is turned off. Monitor is set to never turn off, pc is set to never go to sleep. In advanced power setting HDDs are set to turn of after 99999 minutes, never turn of network adaptors or put anything to sleep ever.
I have also been to device manager and selected never turn off network adapters (just in case)
I use my remote to turn on my TV and AMP. HDMI signal to TV and optical audio to AMP - no HDMI pass through of AMP.
When I switch OFF the AMP and TV the computer stays awake no problems. If it has been a few hours and I return and switch the TV and AMP ON the PC goes to sleep! I then need to use the power button on the pc case to wake it up again.
If I turn the system off and back on immediately, the pc stays powered on. It only arises after a few hours. (not sure how long exactly

This makes no sense, why would Win 7 go to sleep when it gets and HDMI signal?

Any help would be appreciated. Cheers.

A:Windows 7 goes to sleep when HDMI monitor is turned ON!

Since you`re using optical for sound, and the fact that no one has replied, I would try a DVI to HDMI cable, see if that fixes the issue.

I have no idea why your PC is shutting down, that makes no sense at all.

Hi and welcome to the forum.

Have you made sure your graphics card driver is up to date?

Have you tried starting your PC up in safe mode and seeing if the problem still persists?

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'.

Also does the task bar appear on the primary monitor or secondary monitor?

Where did you get these? If from AMD, they may not work well because laptop manufacturers are infamous for customizing their hardware to the degree that only they drivers THEY provide work well. You should use the drivers from the laptop manufacturer's website. IF you're already doing that, there may be nothing you can do.

Hey! So I'm running my audio via HDMI from my graphics card and it plays through the speakers built into my monitor.

When I first did the Win 10 update I had no audio whatsoever, and followed some suggestions on online forums that lead me to disable the Realtek High Definition Audio which I did and upon a reboot- my HDMI audio was working.

But then I had another weird issue. My PC is set to never sleep as I use it as a media server, but my screens turn off automatically after 10 minutes. What im finding is that when I wake up my monitors the audio stops. When I view playback devices I can't do any tests because "the device is already in use by another application"

(note: I have the checkbox for allowing an application to take exclusive control of a device un-checked).

So far there are only 2 ways to restore audio. 1) restart the PC. 2) go into device manager > Sound, video and game controllers > AMD High Definition Audio Device > Disable... wait a few moments > Enable.

Any help/advice greatly appreciated!

I have a Yoga 11s that started having hdmi connection issues about a year ago and has recently quit connecting to an external monitor via HDMI completely. We tried upgrading to Windows 10 to see if that would overwrite any software issues - no luck. The HDMI port actually appears loose. I did an extensive search of the forum and found posts that recommended cutting down the rubber around the base of the hdmi cord - tried that and at least I had a little activitiy - in the upper right hand corner of the external monitor up popped a box that says DVI then VGA then HDMI - but then says No Signal. Tried the graphics card update recommended on a post from long time ago and a popup indicated I had a newer version already installed. I have taken it to a laptop repair place - said they couldn't get parts from Lenovo. I found an "authorized" Lenovo repair shop locally - when I called they said they only work on business machines Called Lenovo and they told me to take it to Best Buy - however since I purchased this directly from Lenovo, Best Buy said they can't work on it. I would rather not send it into Lenovo because they tried to charge my hubby hundreds of dollars when his 15 day brand new laptop quit working, claiming damage - luckily extensive pictures taken and dated prior to sending it in thwarted that attempt at extortion. Does anyone have any suggestions?

Oftenly, I was using my y700 with an external LG monitor conneted via HDMI cable. Sometimes the signal was lost for a few second when I accidentely touched or moved the cable, but I thought it was the cable's fault. The problem reappeared with an increasing frequency until yesterday when the signal was completely lost and I coulnd't bring it back. Today I managed to have an image for a few seconds until I adjusted the cable and it went blank again. So I tried a different HDMI cable, but it didn't helped. I also connected the monitor to my old PC and it was working fine with both cables. I tried to reinstall the Intel drivers, but it didn't helped. Both device menager and the Intel control panel are detecting the monitor and the monitor itself doesnt seem to be in the saving mode either, however, there is no image at all.Is the HDMI port broken then? The monitor and the cable are working fine with a different PC.

Before I wander off to buy a MiniDisplayPort to HDMI adapter and an HDMI adapter:Can someone first-hand confirm or disconfirm if the OptiPlex 9030 can be used as an external/second monitor via the HDMI IN (for my MacBook Pro/in general)?
According to ZDNet (on the 9030) it is possible:
"...plug in an external video source (via HDMI)..."
According to this forum (but on the 9010) it is not possible:
"...I would like to inform you that both VGA and HDMI ports on the system are TV out connection... you won't be able to use this system as display only for a different system or laptop...."
Is it that the 9010 does not have HDMI IN and the 9030 does have HDMI IN (and hence the 9030) does work as an external monitor?
Thank you in advance for your help!

A:Can I Use the OptiPlex 9030 as an (External) Monitor via HDMI IN?

The setup guide shows you have one 19-pin HDMI-input port (#11) on back of the monitor so you should be able to connect an external video source, assuming the source puts out a compatible HDMI signal.
You may need to use the On-Screen Display (OSD) buttons (#6) to configure the display to accept the signal from the HDMI-input. The setup guide doesn't list the OSD options so you may have to figure those out yourself. The OSD buttons are on the right edge of the screen just below the optical drive.

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.
