I understand you are facing some issues connecting your computer to some projectors and the display flickers. Please accept my apologies for any inconvenience this is causing you. Allow me to help you with this issue you are facing.
In this case, I would like you to perform a manual update if the graphics drivers. In order to do so, please download the latest graphics drivers using the following link: https://downloadmirror.intel.com/27412/a08/win64_184.108.40.20601.zip
Then, for you to install the drivers please follow the instructions given in this YouTube video: https://www.youtube.com/watch?v=S1KzoQDjMMY
I can see that the computer you have is manufactured by Toshiba. Please be aware that the driver I am sharing with you is a generic driver from Intel® and some features of it might not be available for your machine, we always recommend verifying if there is any update with the manufacturer of the computer. Nevertheless, we can try to perform this troubleshooting step.
Please let me know the results.
Unfortunately, it did not help. I see the Intel Graphics Control Panel looks different, but otherwise, same issue of flickering and off.
I checked my new driver version after I performed what you indicated above, and it is 220.127.116.1101 from December 18, 2017.
See the snapshot of fuzzy distortion prior to it going out and returning to just do the same. A cycle of quick image, distortion, and blank.
I tried both with VGA to HDMI adapter as well as straight HDMI. Also please tell me what my resolution and refresh rate setti8ngs should be. I thought it had to be under 60 Hz. See attached.
I really apologize that the troubleshooting steps I attached did not work for you.
I can see from the image you attached that the refresh rate on the Intel® interface shows 60Hz. Even if the refresh rate would be 59Hz that should not be a problem.
As I mentioned, the driver I attached on the last post was a generic driver from Intel®. In this case, we can try to install the drivers provided directly from Toshiba*. Please download the drivers by clicking here.
In order to complete the installation please uninstall the current drivers, restart your computer and then, install the drivers I attached.
OK, We got very, very close to those Toshiba drivers working. They were dated June 2017 I think.
However, it only worked when I went with HDMI to VGA adapter. (The projector in one class was VGA only.)
No freezing, flickering or anything. It was great.
Then I went to an HDMI only projector and that is when my troubles began. I restarted the computer and the adapter reverted to some 2015 version. See attached. I tried reinstalling the Toshiba, but every time I restarted it reverts back to something that is not working. 2016, 2015.
What can I do? Also, I uninstall, restart and the driver automatically installs itself.
Also, what settings do I enter for scaling etc here in this one?
I really apologize this issue persists.
We can try another way to solve this problem that you are having with the Device Manager.
1. Go to Device Manager and double-click on Display Adapters.
2. Right-click on the Intel® HD Graphics input.
3. Click Uninstall and reboot the system.
4. Please repeat the steps above until the Display adapters dropdown shows "Microsoft® Basic Display Adapter" when this happens please install the Toshiba* drivers I attached before.
In addition, the settings attached on the last image are fine.
Let me know the results.
