Duplicate Screen Not Working
I am having the same problem. When I hit the windows button and 'p' i get a menu that includes screen 1, screen 2, duplicate or extend. When i hit duplicate, my 2nd screen goes black. When i use settings/display duplicate is not even an option. I need to be able to duplicate my screen as I do a lot of presentation.s.
- This causes the HDTV to not be able to sync to the signal from the notebook computer. As the HDTV does not recognize the resolution the screen on it is blank. However, while in DUPLICATE mode if you change the resolution of the notebook computer to 1366x768 then both the notebook computer and the HDTV do display the video.
- Extending the desktop expands the work area across both displays. Extending is most commonly used to get more workspace. Use only one video source per display device. Do not connect two cables to the same TV or monitor unless it supports picture-in-picture. Extend or duplicate the desktop with a second monitor.
I have a Dell XPS 15 L502X. Graphics card is a NVIDIA GeForce GT 525M.On my desk, I use a Dell IN2020MDigital monitor connected via laptop’s HDMI port. When i go to meetings, I also use a Toshiba projector connected via laptop's HDMI port.
Duplicate Screen Not Working
With Windows 7 I could use PC Screen Only, Second Screen Only, Extend and Duplicate.I upgraded from Windows 7 to Windows 10 andI can no longer Duplicate the displays. However, PC Screen Only, Extend, and Second Screen Only will work.Troubleshooting so far:1. In Device Manager I have uninstalled both the IN2020M and the Generic PnP Monitor and restarted. They were added back but no change.2. The NVIDA driver that came with the Windows 10 upgrade was v353.62.
I found that NVIDIA released a new driver on Aug. I downloaded and upgraded, but the problem persists.Can anyone help? I have a Lenovo W530 that I use for presentations and also for connecting to HDTV at home. It was originally a Windows 7 Pro machine, but I upgraded to Windows 10 Pro in May 2016. There were no problems with the initial upgrade to Windows 10. I have twographics cards, NVIDIA K1000M and Intel HD 4000.In June 2016 I started to use a Lenovo USB dock. This introduced a third and unnecessary graphics driver, one that is of lower quality than the other two.
It is manufactured by DisplayLink. I recently removed the dock and all of its drivers permanently.When the Windows 10 Anniversary update (Build 1607) came through in September 2016, the dock and its drivers were still attached to my W530. I got a security notification from Windows after the update that DisplayLink had been removed from my computer becauseit is not Miracast compliant. This is when I discovered that wired Duplicate Screens were longer an option in Windows 10 Build 1607 on my W530.I took the W530 to Lenovo Premium Support and they discovered after 3 hours of testing that the problem could NOT be solved by reinstalling drivers.
My only option was to reinstall Windows 10, for which I had no back up disks, only a system image. I decidedto leave the W530 as is. Duplicate Displays are a minor issue relative to what this machine can still do.Then I realized that after the Anniversary Update, Windows 10 can project screens wirelessly. It turns out that wireless duplicate displays work on my W530 in Full HD. That takes care of HDTV.For presentations (assuming only a wired projector) I bought an IBM refurbished Lenovo W530 with Windows 7 Pro for $500. This was much less than the replacement cost of my software on my Windows 10 W530.While this may not be considered a complete solution, I would say you are wasting your time with anything else.1011::10001011::1000.
Thanks for your advice Noel. Here is what I did:I installed and ran Intel Driver Update Utility from Not sure if it worked.
It just says “Product Detected” followed by an empty field and “Current Driver Installed” followedby an empty field. Same results on IE and Chrome browsers.From p20 of ASRock manual: 2. If you have installed onboard VGA driver from our support CD to your system already, you can freely enjoy the benefits of dual monitor function after your system boots. If you haven’t installed onboard VGA driver yet, please install onboard VGA driver from our support CD to your system and restart your computer.I downloaded VGA driver from the Setup.exe from the downloaded VGA folder gets: This computer currently contains driver versions newer than the version you are about to install.
Are you sure you want to overwrite the following drivers with the older versions?Intel HD Graphics Family (8.)Intel Display Audio (6.14.0.3074)I clicked “No”.Where do I go from here?Wolfram H Volpi. Sounds like you made the right choice, not overwriting the driver with an older copy.I'm not sure I can advise you on further Intel driver details, in that I don't have your exact hardware configuration (in fact, I have no Intel-based displays at all). My advice to update the display driver is very general, and solves a surprisingnumber of problems.Are you able to use Extended Desktop mode? In other words, is the problem you're seeing where the monitor thinks it should power down not limited to just Duplicate Display mode?It occurs to me as well that you might want to check your power-saving settings. Click Start, type power into the search box. When Power Options comes up, click it.
Duplicate Display Not Working Windows 8
Click the Change plan settings link next to the plan you have selected. Try a different setting for Turn off the display.I hope some of this helps you.-Noel. Those are all good suggestions.I changed power plan to 'Turn off the display: Never' but that made no difference.I changed to 'Extended Displays', and that worked fine.So I borrowed my neighbor's D-sub monitor.I swapped my D-sub monitor for my neighbor's D-sub monitor and updated the monitor driver.As before, 'Extended Displays' mode has full 1920 x 1080 resolution.But 'Duplicate Displays' mode is different.Now both monitors display in duplicate mode, but the maximum Screen Resolution option is 1280 x 1024, which is the native resolutionof the D-sub monitor. The DVI-D monitor has a native resolution of 1920 x 1080.I would like to have 1920 x 1080 resolution when the D-sub monitor is turned off.The workaround remains the same.There is a way to get 1920 x 1080 resolution, but it involves manipulating the power cord:.During boot up, power cord of the D-Sub monitor is unplugged.When the D-Sub monitor is needed, plug in it's power cord.Remember to unplug the power cord when your done.It doesn't look like duplicatedisplays are going to play nice on my system. I do appreciate your advice none the less. Noel,Windows help doesn't say anything about identical resolutions for duplicate disaplys, I looked:Windows Help and Support 'Connect to a projector'I borrowed my mother's D-Sub CRT monitor and plugged it in.If the CRT is turned on after boot, both monitors show duplicate displays at 1920 x 1080 resolution.If the CRT is already on at boot-up, then both monitors show duplicate displays at 1280 x 1024 resolution.At least I don't have to manipulate the power cord, so that's good enough for me. Unfortunately I need to return the CRT to my Mother.Wolfram H Volpi.
