I have a second monitor which is a Philips 1080p 40 inch TV (that I switch the HDMI inputs to alternate between cable and a second monitor).
When I play streaming video from YouTube on the monitor, the display blinks on and off continuously. This does NOT happen when using the Philips for TEXT displays (outlook, explorer, etc.)
The fix is easy.
First, make sure your second monitor (HDTV) is in “PC” mode. (This is not the fix in itself).
Secondly, I have the most current NVIDIA drivers installed.
Go to NVIDIA CONTROL PANEL (right click on an empty desktop)
Click ADJUST DESKTOP COLOR SETTINGS
click on your secondary monitor name (in my case, PHILIPS)
You will see a dropdown box appear.
Set “content reported to the desktop” to “Desktop Programs”.
Your secondary monitor should now be rock stable while watching videos.
let me know if this helped you!
Out of the box, the Watchguard Firewall WebBlocker content filter does not permit YouTube (and other streaming videos) to play through the proxy and into your network.
To fix this, do the following:
- Log into the Watchguard Firewall
- Presuming you have already setup a Firewall proxy and are using the WebBlocker to filter content…
- Go to Firewall->Proxy Actions, and EDIT the current proxy you have custom defined.
- Go to HTTP RESPONSE->CONTENT TYPES
- ADD a new action, (ALLOW OR AV SCAN), Pattern match, video/*
- Retry playing your video (you may need to close out of your web browser and open it, and try another video, but this should solve the YouTube and other streaming video issues).
If you are having problems with iPhones or iPads (or any other device) playing through your Watchguard WebBlocker proxy (via your Watchguard firewall), the fix is very simple.
Presuming you have one of the latest firmwares (11.6.x as of today) and are using WebBlocker with a proxy combined with the content filtering…
Log into the Watchguard
Go to Firewall->Proxy Actions
Select and Edit the proxy setup you are using in your network. (you must NOT be using a predefined one, you must make your own).
Go to HTTP Proxy Exceptions
add the following:
so that your entries look like this:
Save your changes.
Re-test your app and the application should play.
This worked perfectly on our network and our i-Devices.
