G50 HDMI Not working for 2d External Monitor

Q: G50 HDMI Not working for 2d External Monitor

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!

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 10.18.15.4248. 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 10.18.15.4248 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.

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

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 :-)

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.

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

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,

Hi,

I have an Asrock ION 330 HT BD with a Sony Bravia 720p attached (HDMI to HDMI). When I start up my PC, the screen remains black. Only after I plug in a second monitor, both screens work just fine. When I pull the second monitor out, the Bravia also stops getting a signal. Seems a bit weird.. How can I get it to work with just the Bravia attached?

Thanks,
Gijs

A:HDMI to HDMI only working with second monitor attached

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?

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?

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?

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.

Hi,
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)..."
www.zdnet.com/product/dell-optiplex-9030/
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...."
en.community.dell.com/support-forums/desktop/f/3514/t/19508673
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.

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.

My XPS13 9350 was one of the first with USB-C port (Thunderbolt 3) only and no DisplayPort, supplied in early 2016. It has caused a lot of headaches. As I tried to connect my external Dell monitor using  a USB-C to HDMI adapter from Dell (part no: 47KD7) there was no external display at all. Dell Support advised me to update BIOS. But it led to a complete freeze of my laptop and Dell replaced the motherboard. (It was a real nuisance as I use my laptop for work!!)
With the new motherboard,  the laptop/USB-C adapter/external monitor worked fine for 15 months. Until one day, out of the blue, the external screen started flickering with an image that was all distorted (cut in the middle). The laptop screen was fine. After a few weeks of flickering, there is no signal at all to the external screen. Moreover, as I connect the adapter in USB-C port the resolution on my laptop screen changes.
I know there have been a lot of issues with USB-C connector on XPS 13 and 15.  I have reduced wifi-power to 50%  but it has had no positive effect (several persons have said on this forum that it helped the video output). 
I am grateful to learn if anybody with similar problems found a solution. Cheers

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.

Hi, We recently purchased two T470 laptops. Both of these appear to have display issues when outputting to an external monitor. Text will appear fuzzy/blurry and after a couple of minutes your eyes starts to hurt from trying to focus on it. Has anybody experienced any similar issues? We also have a T470s that is doing the same but it even has blurry text on the built in screen.

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.

 Dear forum,  yesterday I bought my new ThinkPad t470. While everything else is working fine, the notebook seems not to be able to detect my external monitor (ThinkVision t2424p), when connecting it via a VGA to HDMI adapter. This setup flawlessly worked with my last notebook. Regardless whether I try to connect the monitor when Windows is already running or when I boot into Windows with the monitor already connected, the monitor doesn't show up in the screen resolutions settings nor does there appear an additional device in the device manager.  Do you know what the problem might be? The apater works fine when used with a different Notebook. Thank you very much, EBM

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 purchased the 5510 with the high DPI touchscreen, running W10 and after some fiddling with it, including going to Windows 8.1 scaling and forcing the non high DPI aware applications to utilize that scaling too, I am really happy with the laptop itself.  
The problem is connecting it to anything else.  I heard that not all HDMI cables would support 4K monitors, so I went to the local electronics retailer and tested it. HDMI worked fine with a 4K screen.  I thought surely it would be able to drive also a standard run of the mill 24in 1920x1200 screen as an external monitor, with different scaling factor.
Nothing at all.  Tried also using HDMI to a HDMI-DVID adapter and utilizing that port, same problem.
The monitor simply gets no signal.  The computer never recognizes the fact that it is connected.  It seems like a case of zero compatibility.  I tried going to other monitor appropriate resolutions, etc. it does not work at all.  
While this is annoying by not being able to use an external monitor when I go home in the evening, or it means I need to buy a new high DPI monitor, what about connecting to a projector.  HDMI is the standard, and no projector runs 4K.  Why have a laptop that you cannot use for presentations?
I am not keen to go experimenting trying to purchase more dongles/adapters/ports for USB C without some idea why the built in HDMI has zero use as a connection to a projector or monitor.
