Flex 2-14 stopped working with an external monitor

Q: Flex 2-14 stopped working with an external monitor

My laptop Lenovo Flex 2-14 has been working fine with multiple displays for 2 years. A few days ago, it stopped recognizing the HDMI output. Notes:The Intel Graphics driver is the latestWindows drivers are the latestIssue:1) When the external monitor is plugged in, I cannot open any folders or the windows explorer. As soon as I unplug the external monitor, the folders can open.2) The Intel HD Graphics control panel's interface is not usable as can be seen in the screenshot below. I have tried restarting, but that does not help. Unplugging the external monitor does not help either. It seems to be permanent. When I click on other menu items of the Graphics control panel such as "Audio settings", the whole screen is blank. Has anyone else had this issue and found a solution to it?Intel HD Graphics Control Panel - Lenovo Flex 2-14

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

I have the USBc to HDMI connector from Dell, to connect my XPS13 to a second LG monitor.
I have been using it without problems for 2 years. I use it every day. Same setup.
Since friday 29/12 it stopped working.
I tried to connect my laptop to different monitors. I did driver updates and even tried to roll back my Intel driver. I disabled the WIFI. (and tried putting it on airplane mode). But nothing helps.
I guess some of those latest BIOS updates, HD driver update, ... caused the problem.
Can somebody please help. It's urgent. I need my laptop+second screen for my work.

I have a Windows 10 laptop and an external monitor. The monitor was working perfectly for a few weeks, until one day I switched on the laptop to find that the monitor was no longer working. Going to 'Display Settings' only showed one monitor, and pressing 'Detect' said 'Didn't detect another display'.

After updating all drivers, then purchasing new leads and adapters for the monitor, I still couldn't get it to work. Then I stumbled upon the 'Hardware and devices' troubleshooter which, after restarting my computer, made it work.

Less than a week later, I just restarted my machine and suddenly it's not working again. This time, the troubleshooter isn't fixing it. Every time, it just says to restart my computer to finish applying updates/drivers but restarting doesn't help.

Anyone have ideas how I can fix this?

Cheers

I've been running this Z580 for a year or so, and updated to Windows 10 a couple of months ago. Both the laptop display and an external monitor (HPw1907 vga) have been working fine. The other day, the external monitor just stopped working.   I check the device manager and the Intel HD Graphics 4000 display adapter is disabled, due to a Code 43. I have tried rolling back to an earlier restore point, I've uninstalled and reinstalled several versions of the Intel graphics adapter, up through the current compatible one. The most recent display adapter driver from Intel is apparently not hardware compatible with this adapter. The funny thing, is that the driver wants to work! On booting, while the black and white Lenovo splash screen is displayed, with the little circular Windows logo circling around, I can move the cursor back and forth between monitors. As soon as the screen turns blue (I assume with Windows drivers loading) the external monitor blanks out and I'm back to one screen.  Based on that behavior, I'm wondering if it's not a display driver that is specfically the problem, since I've loaded up the latest drivers several times, but if maybe a recent Windows update has sneaked in a driver or component for something else that is causing the Intel driver to crash. Any thoughts?  Back in earlier versions of Windows, you could have the system load one component at a time during boot, so you could check for incompatibilities. So, if the... Read more

I just got my Flex 5 15.6" with the 4k screen resolution.  My desire is to have two external monitors plugged in via USB3 (cable creation usb3 to HDMI adapter box) and HDMI ports. But it seems the highest resolution I can get via HDMI port is 1980x1080 (which is weird considering the laptop screen resolution is 3840x2160). For the USB3 adapter to HDMI, I can do a little better (2160x1440 i think), but not the desired 2K (2580) that i want with these monitors. Can anyone help?  Not sure if I'm missing something.  I've opened both monitors in the preferences for display and the recommended and max listed resolution is 1980x1080.  Maybe a driver or something... ? Thanks!

The touchscreen on my Flex 15 stopped working. I am not sure exactly when, but in the last few months.  I am already on Win10, and it has worked fine since the Win10 upgrade over a year ago.  In Device Manager, I can see the HID Touch Screen entry.  I tried uninstalling and deleting it, followed by a restart.  Reinstalled itself on start-up, but no joy.  It claims to be working.   I have seen other similar posts saying to delete entries under Mice... but I don't see any Touch Screen entries there.Interestingly, I see most of the drivers have Event dates of 2-Jul 2017, saying "Device migrated". I am suspecting some delightful Micorsoft "improvement" on that date may have been the cuplrit, but I also feel like the touch screen may have been working after that date.  Unfortunately, I don't use the touch screen very often, but I DO need it now and then. Thoughts?

The issue has already solved, just writing for thos who might have the same issue. One day when I turned the notebook on, the keyboard and touchpad did not work. Restarting ddi not help.The only thing I put my attention that time was the battery is almost discharged, so I turned the notebook off, closed the lid, and plugged it in. The next day I turned it on, and everything was working.  Another idea on why it happened: when the notebook lid opens and closes, it might switch to tablet mode, so that the keyboad and touchpad are off.

I just upgraded all of our Flex Laptops to Windows 10 and found that one of my users has a problem with her secondary monitor (connected through the HDMI port). It was working with Windows 8.1 with no problems. After the upgrade and seeing the problem I uninstalled the Intel HD Graphics Family driver with the "Device Manager" (it showed an error code 43). When it scanned for new hardware it found a new driver for the Video Card (ver 10.18.15.4279) after the iunstallation the error code (43) still existed and the monitor still had "No Signal". In researching the Lenovo site for the driver for this card it said the latest was version 10.18.15.4248. I dont know, do I go back to '4248', is there a different solution that works?

I have been in touch with the manufacturer of the portable HDD's but so far have not had any luck. Here's a quick summary of the problem.

I own 3 WD Passport devices, two of the older format (using USB 2.0) and one newer one (USB 3). All three have suddenly stopped working. I used the newest device plugged in to my xbox to listen to music on the day that the problem began and used the two older devices the night before.

I first noticed the problem when I plugged the newer device in to my laptop and nothing happened. The light appeared on the drive but it did not appear in windows explorer. When the other two older devices are inserted the "Safely Remove Hardware" box appear in the bottom right of the screen with the option "remove External HDD" but neither shows up in the windows explorer. The two older devices are partially recognised in device manager but only as External HDD.

After discussions with the manufacturer they advised me to uninstall the devices through device manager and also supplied me with a new cable to try. None of these solutions have helped.

I initally thought this was just a drive getting old but I have two laptops and the same problem appears on both. The devices no longer work on my Xbox either.

I can't explain why all three would suddenly stop working on a number of computers/my xbox. I hold over 800gb of data between the 3 devices and I cannot afford to lose it.

Any help would be greatly appreciated. I'v... Read more

Hi,

I have an HP Pavilion DV6000 laptop which I often use with an external monitor on extended desktop mode. I will often switch the monitor between this and another laptop. One time when I was switching between them, the monitor connected back to this computer, but the screen stayed black. Looking in the settings I can tell that the monitor is being recognized by the system, and I can drag my mouse into the area that would be being shown by the monitor, but it is just not showing anything.

I have tried this PC on another monitor and it also does not work. Conversely I have tried this monitor on another PC and it does work, so I know that something went wrong with the machine.

I have tried to uninstall and re-install both the graphics card driver and the monitor driver to no avail.

I am on Windows 7.

I have a Lenovo ThinkPad T540p, to which I have had 2 Seagate 3Tb external USB 3.0 drives connected and working fine for over 1 year. Usually these are connected via the docking station, but when I travel, I often take one of the two 3Tb drives with me and connect to a USB 3.0 port on the laptop itself. I've been using this setup with my previous T500, and with this T540p since I purchased it in July 2015. Suddenly a few days ago, I found that neither of the drives were being recognized at all. They don't show in in Windows Explorer, and they don't show up in Device Manager. The drives are fine. I can connect them to a cheap Dell Inspiron desktop, I can connect them to the USB ports on my router, and they work fine. But they no longer are recognized when plugged into any of the USB ports on the ThinkPad. Other USB devices are working fine (mouse, speakers, headphone, UPS, hub, printers, barcode scanner, etc.). I am guessing that there was either a Lenovo or Windows software update which caused this problem, but I cannot determine what this might be. The USB drivers have not changed. T540p16Gb RAM500 Gb SSD primary driveWindows 8.1 Professional 64-bit Anybody have any ideas on this?

A:5510: Audio from websites not working when external monitor is also hooked up. (But Skype sound still working)

Hello. What might be happening is after you connect to the external display, the audio switches to HDMI audio. To get the audio to emit from the laptop's speakers again, go to the Windows Sounds dialog and make Speakers the default playback device (right click). You might have to do this every time you connect an HDMI cable.

Then try to boot into Windows and see if it shows up. If not, try UBCD to boot into hard drive diagnose of the brand of the HDD and do short and long test on the drive.

Hi, have you tried switching the monitors around so they are both plugged into the VGA/DVI/HDMI they are not usually in?

This will identify if it is a GPU problem or a Monitor Problem.

If it is a GPU problem you may consider doing a system restore to yesterday or the day before and see if that fixes anything.

Try that monitor on another computer known to be working.

Hello, I have a KDSUSA K717s 700p 14" monitior and the other day it mysteriously stopped working. I was reading the update from bungie.net (Halo's website) and suddenly it went kapoot. The monitor was not moved at all when it happened. I had previously had some trouble with the VGA cord, which plugs directly into the back of the monitor's motherboard, so to speak, where there was a severe lack of green color. I narrowed down the section of the cord where the faulty green color was, but I was unable to find a break (there was a big red, blue, and grey wire. hopefully the grey had green.) in the cord. I then wrapped it up in electrical tape somehow it corrected the lack of green. So everything was fine and then suddenly, just like that, I heard a little noise and then the monitor went black. I opened it up to try and see what was the problem and I could not find any. I even went as far as the actual liquid crystals to see if there was a problem. Does anyone have any ideas as to what could be wrong? BTW, there are no faulty capacitors as far as I could see. Thank you.

Hello everyone,

I've been using my TV (The brand is Olevia, I can get the model number if it's needed) as a second monitor while playing video games on my laptop (A Lenovo ThinkPad SL400 running Windows Vista) via HDMI cable.

It worked out for a while, but then my computer crashed while I was playing, and it hasn't worked since.

Whenever I plug it in, the screen goes black as if it were working, but the TV displays "Invalid Format".

The biggest change I can see is that under Display Settings, it always says that there is a second monitor plugged in, when there is not.

My system consists of a dell dimension w/Intel Pentium 4, 2.8 Hz. It has 512 MB of ram and a 140 GB hd. I'm running XP home 2002, sp3. I'm connected through ATT DSL elite. My monitor suddenly stopped working. I tried another monitor and it did not work either. I tried the dead monitor on another pc and it worked???

RELEVANCY SCORE 56.8

There are a few other posts about second monitors not working when upgrading to Windows 10, however in my case it was working back in December 2015 but has since failed. I didn't try it again until March 2016 as I didn't need a second monitor at the time but now I do.
 
I connect over a HDMI to DVI cable. When I plug the cable in the monitor goes from "Check Signal Cable" to just a black screen. In both windows display and the Intel HD520 Graphics properties there is no monitor detected and no way to select anything other than single monitor from the multiple display options.
 
I've tried rolling back drivers, updating drivers (even the latest beta), manually installing drivers - nothing works.
 
As I said, when I first tried it, there was no problem - connected the cable and there it was. So what's happened?
 
Ok, I've tried this with my work monitor and it's fine, so maybe something has happened to my hardware...
