FAQs Frequently Asked Questions


Features


1. How do I use Wi Display without a local area network?

Wi Display can still be used in environments without a network established as long as both devices are Wi-Fi capable. To do this, you’ll need to set up an ad-hoc network connection. An ad-hoc network is a direct peer-to-peer connection between your computer and the display device. This can be set up without any existing network or when network settings prevent you from connecting normally.

2. How do I setup an ad hoc (peer to peer) network on Mac OSX?

Step 1: Click the Wifi icon in your menu bar.
Step 2: Choose "Create Network…"
Step 3: Give your network a name, set up a password for your network if you wish.
Step 4: Click "Create".
Step 5: Now on your target device, go to the main settings, and connect to the network you've just set up as your Wi-Fi connection.
If you can’t get connected to your target device, try disabling the Ethernet port on your computer, so only your Wi-Fi connection is active.

3. How do I setup an ad hoc (peer to peer) network on Windows?

Step 1: Go to the Start Menu and type wireless in the search field.
Step 2: Click Manage Wireless Network.
Step 3: Click Add.
Step 4: Click Create an ad hoc network.
Step 5: Click Next.
Step 6: Give your network a name, set up a password for your network if you wish.
Step 7: Click "Next".
Now on your target device, go to the main settings, and connect to the network you've just set up as your Wi-Fi connection.

4. Can Wi Display connect to multiple displays?

Wi Display supports connecting to multiple devices.
To do this you’ll need to install the Client app on to each device you wish to use as a display.
To connect additional displays you’ll just click on the ‘Connect’ button to add up to four devices shown in the Host software’s device list.

5. Does Wi Display stream audio to the display devices?

Yes. Wi Display streams audio to the display devices with 2 modes: System Loopback Sound mode and System Input Sound mode. With the System Loopback Sound mode, you will hear exactly the sound from your primary computer in the display devices. And with the System Input Sound mode, you will hear the sound that recorded from primary computer's system sound (microphone, headphone, etc.).

6. How do I record media content from the extended display?

Start the Wi Display app in your device that you want to use as extended display. In the Wi Display Host app of your main PC, connect to the extended display.
After the extended display get connected, tap on the Record button in the tool bar of the extended display screen.

7. The client app is not downloading/installing on my devices.

If you are having difficulties downloading or installing the client app on to your iPad, iPhone, iPod Touch, Android, Windows Phone, Windows 8 or Mac OSX device, try doing a hard restart on the device and trying again.
If you still have issues with this you may need to contact the support team for the App Store, Google Store, Windows Store you are purchasing from and verify your Store settings are correct.

11. How can I prohibit an extended display from controlling my host computer?

There are 2 ways to do this:

  • On extended display, disable remote control function by tapping hand icon on the tool bar.
  • Or on WiDisplay Host, turn off the "Control Mouse & Keyboard " function by tapping mouse icon beside that extended display.

12. My Host computer screen becomes no images when connect to extended display although the extended display still presents images normally. What should I do?

This problem appears when your host computer display doesn't support the resolution of the extended display. To resolve this, you need to disconnect to host computer from your extended display first. After that, in your computer, on Settings tab of WiDisplay Host app, you need to change "Video Resolution" setting to the resolution that your display supports or simply choose "Current Resolution".Finally, try to connect to your extended display again.

Mac Troubleshooting


1. When I install WiDisplay Host, I got the message "WiDisplayHost_****.pkg” can’t be opened because it is from an unidentified developer." and cannot install, what should I do?.

Open your Mac OSX System Preferences, on the "Security and Privacy" section, change the "Allow apps downloaded from" to "Anywhere". From now, you can install WiDisplay Host normally. After installing, you can change back the "Allow apps downloaded from" to "Mac App Store" or "Mac App Store and identified developers".

2. I do not see the menu bar icon after installing the server software.

If you do not see the new icon in the menu bar try opening up your Applications folder and running the Wi Display Host.app located there.

3. How do I uninstall Wi Display Host from my Mac?

To uninstall WiDisplay Host from your Mac, Please go to /Applications/Utilities folder and run WiDisplay Host Uninstaller.app. Note: Administrator password is required.

4. How do I reposition my display?

When Wi Display is connected go to System Preferences>Displays>Arrangement in order to position where you’d like the secondary screen in relation to your primary screen.

5. How do I make Wi Display as extended display of primary display?

You can do this by disabling display mirroring in System Preferences. Open up System Preferences>Displays>Arrangement and there will be a check box at the bottom that says ‘Mirror Displays’ which will enable/disable you to screen mirror mode.
Or you can uncheck "Mirror Displays" setting on Wi Display Host.

6. How do I use Retina resolution on Mac OSX and iPad extended display?

Open Settings tab in the Wi Display app of your Mac OSX/iPad. In the "Extended Display" section, turn the "Use Retina Resolution" setting to ON. Note: This option is available only in Retina Display devices.

Windows Troubleshooting


1. Nothing happens when I click on the Start Menu icon after installing.

If you installed the server software from edssglobal.com and it completed successfully and rebooted your machine Wi Display is already running.
The Wi Display server software runs in the background and can be accessed through the new icon it has placed in your system tray, by the date/time. The icon is blue and looks like two small monitors. You may need to press a triangular button in order to show your hidden system tray icons.

2. The server installation does not finish properly.

If you have trouble with the installer not finishing check to see if your Windows Firewall is disabled.
If the Firewall is disabled during the installation process the Wi Display installer sometimes will not think it has sufficient permissions in order to install all of the software.
Turning the Windows Firewall back on and running the installer again will fix this.

3. I do not see the system tray icon after installing the server software.

Press Ctrl+Alt+Delete to bring up the Task Manager. Find the WiDisplayHost.exe process and terminate it. Use the Start Menu to start Wi Display again and the system tray icon should be present.’

4. I can't here the sound from Windows XP server, what can I do?

Windows XP is an old operating system, so WiDisplay Host app cannot transmit the loopback audio automatically (like Windows Vista, Windows 7 and Windows 8), you will need to do the following actions:
Step 1: Right click on the Speaker icon on the notification area of Windows XP (usually on the bottom right of screen).
Step 2: Choose "Adjust Audio Properties".
Step 3: In the "Volume" tab, click on "Advanced..." button of "Device volume" section.
Step 4: In the "Master Volume" dialog", choose "Option" >> "Properties" menu item.
Step 5: In the "Properties" dialog", choose "[Your Sound Card Name] Audio input" in the "Mixer device" combobox.
Step 6: Check the "Stereo Mix" check box then press OK. The "Recording Control" will be displayed.
Step 7: In the "Recording Control" dialog", Select the "Stereo Mix" checkbox. From now, you can here the sound from Windows XP system on your extended displays.

Note: If you want to here the sound from Micro or Line In, just select "Mic Volume" or "Line Volume" in the Step 7.

5. How do I uninstall Wi Display?

You can uninstall Wi Display by going to Control Panel > Programs & Features > Uninstall a Program > and select ‘Wi Display Host" then choose uninstall.

Connection Troubleshooting


1. Connecting on Public Networks (Coffee Shops, Hotels, School Campuses, etc.).

Wi Display requires certain ports open on the network in order to connect. Often times large public networks have these ports blocked for security reasons. Because these networks are usually not networks you can get settings changed on it is unlikely you’ll be able to connect in these spots.
However, you can use an ad-hoc network connection instead. Note, unless you have two Wi-Fi interfaces, or an Ethernet connection to the network you will not be able to access the Internet whilst using an ad-hoc network connection.
Instructions for creating an ad-hoc network can be found above, in the ‘Features’ section of the Wi Display FAQs.

2. Connecting on Office/Corporate Networks.

Wi Display requires certain ports open on the network in order to connect. By default, Wi Display uses 3 serial TCP ports: 30000, 30001 and 30002 for video, audio, and control communication. You can adjust these ports in the Settings of Wi Display client app on your devices.
Often times corporate or office networks have these ports blocked for security reasons. In these environments it is often possible to get the network settings adjusted so that you can connect. We suggest contacting the IT department and requesting their assistance to adjust the network accordingly.

3. Connecting on Home Networks.

Connecting Wi Display on your home network should be as easy as having both of the client and the server software running.
However, in the event that you are unable to connect on your home network we suggest temporarily disabling any firewalls that are running. This includes network security software and anti-virus software. These are the most likely culprits for preventing Wi Display from connecting. Once you are able to find out which program is causing the problem you can edit that application’s settings to allow Wi Display to connect.
If you have disabled all of your firewalls and are still unable to connect it could be a router settings issue. Consult your router’s manual for instruction on how to access the router’s web preferences page and verify the following settings:
By default, Wi Display uses 3 serial TCP ports: 30000, 30001 and 30002 for video, audio, and control communication. You can adjust these ports in the Settings of Wi Display client app on your devices.

4. My Display Device does not show up on Wi Display Host's list to connect to it.

If you are unable to see the device in the list of devices to connect to it most likely means that there is a firewall or network settings in place that are blocking port 5353, which is the port Bonjour uses to advertise the Wi Display devices.
On a Windows computer this can also be indicative of Bonjour not being properly installed. We recommend trying to reinstall the newest version of Bonjour.

5. How can I tell if my network settings are preventing Wi Display from connecting?

Try setting up an ad-hoc connection. This will create a peer to peer network between your devices so you can isolate if it’s the network causing the issue or something else.

6. Wi Display connected fine before but now will not reconnect.

If you are suddenly unable to connect after being able to connect fine previously try removing Wi Display from running in the background on your devices and run it again.

7. My Windows/Mac Firewall is disabled and Wi Display still will not connect.

If you have completely disabled any firewalls or software that may be preventing Wi Display from connecting the next thing to check is the router. Consult your router’s manual for instruction on how to access the router’s web preferences page and verify the following settings:
By default, Wi Display uses 3 serial TCP ports: 30000, 30001 and 30002 for video, audio, and control communication. You can adjust these ports in the Settings of Wi Display client app on your devices.

8. How do I add Wi Display as an exception to the Windows Firewall?

  • Go to Start>Control Panel
  • Click on ‘System and Security’
  • Under Firewall, click on ‘Allow program through Firewall’
  • Click the ‘Change Settings’ button at the top
  • Click on the ‘Allow another program…’ button
  • Navigate to and select the WiDisplayHost.exe in C:\Program Files\Wi Display Host folder.

9. How to make my host computer auto connect to my extended display whenever I launch WiDisplay on extended device?

On WiDisplay Host, turn ON the "Auto Connect" function by tapping the network shape button beside the extended device.
Or you can turn on "Auto Connect" of "Discovered device's permissions" setting on Settings tab of WiDisplay Host.
