Hello Slideguy, thanks for joining the Intel Community.
Please let me know something, are you trying to connect 2 TV to your Lenovo system or just one TV?
Can you try doing a system restore to the latest working stage?
Hello Sylvia ~ Thanks for the reply.
I'm trying to connect to just 1 TV. I tried doing a system restore, but Windows 7 gave me grief - a message about turning off my virus protection. I tried that and it failed again. Online material suggested I try it in Safe Mode. That's when I ran into the Windows 7 absence of Safe Mode -- unless you tap your finger continuously while booting up. Then you get a familiar menu of commands, including Safe Mode.
I will give it a try, but from the reading I've done in other forums, it doesn't work. And if Windows Updates caused the problem to recur, I'm a sitting duck for it to happen again.
I'll try System Restore and see what happens and report it back here.
This is my first time doing a system restore on this computer. I discovered that Windows deletes the System Restore files and creates a new SR Point every day!
So I'm hooped as far as that goes, I guess. And here I sit, waiting patiently for someone to have the answer. Well, trying to be patient.
Would you please attach the DX Diag report for your system as soon as possible in order to check some information from your system? (Start -> Run -> dxdiag -> Save All Information).
Slideguy, I was searching for drivers at Lenovo’s website and I found the following list of drivers http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-edge-laptops/thinkpad-edge-e431/?tabName=Manuals
It looks like the latest graphics driver available is version 3372 http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-edge-laptops/thinkpad-edge-e431//downloads/DS035030
I installed the driver, but it didn't fix the problem. Still two black screens.
When I read this page: Multiple Displays Frequently Asked Questions (FAQ) I see 3 settings for multiple displays, and instructions on how to enable clone, extended or 3-display modes. None of these settings are available to me. The Operating Mode drop-down menu lists Single Display with a check mark, and Primary Display is the built-in display, and that's it.
Any idea why I only have Single Display? That seems to be a fundamental problem.
I did some reading on this forum and found a thread from last year where you were helping someone with a similar problem. You advised him to reinstall the graphics driver. I've already done that once today, but thought to do it again.
Then I used the Windows Key + P to Extend the display. A bubble popped up on the taskbar with a message about using an 800 x 600 if I wanted to Clone. That's the first time I've seen that message. I went to the Intel HD Control Panel, and to my surprise, I saw a different screen. (See image)
I clicked apply and was asked to save the settings, which I did.
I connected the HDMI cord to the laptop and turned on the TV. The laptop screen went black. Same for the TV.
I revisited the Intel HD Control Panel. Once again, it was showing only a single display. (See image below.)
I don't know how to interpret this, but something sure is wrong!
Since you have tried the latest drivers from the Lenovo* and the issues persist, you can try with the generic version of the driver, please Note:
These software drivers are generic versions and can be used for general purposes. However, computer original equipment manufacturers (OEMs) may have altered the features, incorporated customizations, or made other changes to the software or software packaging they provide. To avoid any potential installation incompatibilities on your OEM system, Intel recommends that you check with your OEM and use the software provided by your system manufacturer. Intel and the computer original equipment manufacturer (OEM) may not provide technical support for some or all issues that could arise from the usage of this generic version of software drivers.
You can download the drivers in the following link:
If these do not work, you should contact Lenovo* directly for more troubleshooting.
Thanks,Siberio. I've downloaded the driver, but before I install it, I'm wondering if in the event there's a problem using, I can reinstall the HD 4000 driver afterwards? I'm not sure what advice I can expect from Lenovo, if any.
Before trying any driver, it is best to remove the older drivers first by uninstalling them through add/remove programs. There would be no problem if you need to switch back to the HD 4000.
I did that,Siberio. But in the end, the fix was simple - and a bit mystifying. I connected the laptop to a friend's TV. Initially, there was no signal when it was set to duplicate. I set it to extend, and my friend instructed me to drag my mouse from one screen to the other. And then my desktop appeared on the TV screen. I brought it back to my TV, and it worked.
I have no idea why the laptop screen didn't go black when I connected it to my friend's TV, but after that, it has worked fine.
Thanks to Siberio and Sylvia for trying to help me through this.
Thanks for sharing the outcome; we appreciate your feedback since this will help other users.
