Problem connecting Lenovo Edge Thinkpad to Samsung SyncMaster T260HD Windows 7

My old crappy laptop broke. Someone gave me this old not as bad Lenovo Edge Thinkpad with I5-M560, Intel HD Graphics.

Restored laptop with factory Windows 7. During a day of security updates, the Samsung TV was working via HDMI cable. After the security updates, I installed a couple of apps. While this was going on, I decided to move the HDMI cable a bit on the desk, and the monitor became "No Signal". I have not been able to get it working again.

Screen Resolution Window says "SyncMaster" and monitor shows "No Signal", so some detection on both ends is there. Only unusual thing is if I hit "Detect" - a third box appears saying "Another display not detected".

The "Device Manager" --> "Monitors" just indicates "Generic PnP Monitor" (and the LCD 1366x768 laptop monitor).

My co-worker wrote:
I've heard numerous problems with connecting video output things to Windows laptops over the years. I think the problem is that it tries to save profiles of things you typically do so when you plug something in again it knows what to do. At that, I suspect you often have Windows v. Intel (integrated graphics) v. NVIDIA (discrete graphics) v. Lenovo/HP (proprietary Windows stuff) all trying to do that same things (save profiles) and fighting with each other.

Any ideas on how to fix this?

I followed the instructions here, and, at least temporarily, the 2nd monitor is working.

I disabled the HD Graphics, and reenabled it. (Caveat: the laptop primary monitor went dark; but reboot using F8 to safe mode got me out of that state.)

I know it is extremely difficult to diagnose problems sight-unseen. But thanks for trying.

I will not be surprised when the monitor stops working again.

You need to run system restore to undo the windows update.

It is obvious the windows update is causing problem.

After you have done system restore, run windows update again without connecting to the external display.

When there are no more windows updates, connect the notebook to external display and let the OS install the driver of the external display.

Funny thing though, the Samsung was displaying just before I moved the cable a little, and that was the moment, it stopped working.

I did go back to one system restore point that only had one security update, but I didn't disconnect the Samsung. If I go back a few more, there were 203 updates that takes 12 hours and many reboots. Do you think I should go back that far. The ones in between only had about a dozen updates.

Have you tried a different HDMI cable?

Not yet. I was planning on trying different cables when I get home this weekend or Thanksgiving.

Power was off and hdmi cable removed. (Have not yet done the restore point again with cable removed.)

In Screen Resolution window, the Display pull-down shows 1. LCD 1366x768. This makes sense to me. But when I hit the Detect button, there appears to be a phantom display called "Another display not detected". Others see this little box also. Is this little non-display window a clue to the problem?

Here is what I see after hitting Detect and go to the Display pull-down:
Lenovo_Screen_Resolution_Window.pngA co-worker told me to get a newer computer. Black Friday is near (but I'm told that the deals are not going to be as good anymore). In any case, I'm concerned that if I get a 40" 4K TV, then it may not work with this laptop.

In the link in the previous post is this advice.
Click 'Device Manager'
Click 'Display Adaptor'  it should now show your graphics card
Right click on your graphics card name and click 'Uninstall'
Once that finishes - Reboot your pc

On rebooting the standard windows driver will install for your graphics card.
Should I try that? Any danger like not getting anything to work after doing this?

Good idea to get a newer computer if you MUST use an external display as the Intel Integrated GPU might not work properly under Windows 10.

I avoided Windows 10 (and Norton), and now using Windows 7 and MSSE. Now cpu hovers around 1-3% when I'm not using it. With now defunct laptop, cpu was hovering around 10-20% all the time (after the latest Windows 10 massive feature update came along last week). No wonder my laptop went dead.

Agreed. Unless your computer was bundled with Windows 8 or 8.1 (which is a total failure from Microsoft), old computer is better to run Windows 7.

It will be a waste of time.

By default, the "updated" display driver will be installed when you restart after uninstalling the driver of your graphics card.

I restarted and rebooted with power off. I'll try the system restore now with the hdmi cable disconnected.

I went to a restore point, did the security updates, installed my applications again.
Then I turned on the Samsung TV, and plugged in the hdmi cable. Still "No Signal".
Time to try another cable.
Also, I followed these instructions to get back my account:

Note also that the folders you see under C:\Users are not accounts. They are profile folders that were created when you first logged on under the respective account. They can exist even when the account behind them no longer exists. You can probably get things back on an even keel like so:

1.Boot into Safe Mode. 
2.Click Start. 

3.Type the three letters cmd into the Search box. 
4.Press Ctrl+Shift+Enter 

5.Click "Run as Administrator". 
6.Type the following command and press Enter:
 net user
 (can you see the missing accounts? If yes, stop right here.) 

7.Rename the folder c:\Users\JohnDoe to c:\Users\JohnDoe.org
 (replace "JohnDoe" with an actual profile folder name) 

8.Recreate the account JohnDoe. 

9.Switch users, then log on as JohnDoe. 

10.Log off from the JohnDoe account. 

11.Delete the newly created profile folder c:\Users\JohnDoe.
 
12.Rename the folder c:\Users\JohnDoe.org to c:\Users\JohnDoe. 

13.Adjust the permissions for the folder c:\Users\JohnDoe so that the user JohnDoe has full access to his profile folder.

Open in new window

But in step 13, while still in safe mode, I got a lot of permission denied while trying to add permissions. As a result, when I log into my limited account, I get a message that I will be using a temporary profile. So, my original account profile is not being seen.

When I look at restore points, the 7th one down has a date where I started this reversion to an earlier date. The description is "Restore Operation" and the type is "Undo". If I choose to restore with that one highlighted, will that take me back to where I was before the restore point attempt?

Ok, I may as well do that. Thanks for trying. I'll take the laptop to a store and see if the salesman can sell me a TV with their cable.

In the link it says to disable / enable every time you start up. Is there a way to write a script to do this since the screen goes blank and I no longer can enable it without powering off and then going into safe mode?

☠ MASQ ☠Commented:
Thanks :)

As far as script goes, try:
devcon.exe disable "Intel(R) HD Graphics 3000"
devcon.exe enable "Intel(R) HD Graphics 3000"

Open in new window


I'm assuming the graphics adapter for the I5-M560 is described as "Intel(R) HD Graphics 3000" in device manager - otherwise replace the bit in quotes with the actual name displayed there.

"Intel(R) HD Graphics" in device manager.
Haven't been able to find a number online for this Lenovo Thinkpad Edge 0301 CTO (Core I5).
Maybe this was the first and didn't have a number?

The IGP is a modified GMA 5700M HD but devcon should work with the device name displayed in Device Manager
