Select a zone, double click it to enter Zone Attributes, then select an image file in Logo Attribute of Zone Attributes as shown below. (Only JPG, BMP, GIF, and PNG file formats are supported for translucent logo.)
2. How can I change the Media duration in a playlist?
Double click the duration of a media file in one zone, and input the new duration. If the duration is 2 minutes, you can input either 00:02:00 or 120 directly. For editing multiple media files in the zone, you can multiple select the media files, and click “Edit the selected media” button
to update the duration in the “Edit Playlist Item” dialog at one time.
3. How to select Playback Mode in the Playlist Settings?
There are 2 modes for media Playback.
1. Keep last frame after media play ends (default)
2. Repeat media in specified time.
If you play the same video file in a loop, choosing #2 Repeat mode will have better performance. Choose #1 Keep last frame will ensure your video won't play again if actual video duration and playlist duration are different.
4. Does WCM support all transition effects on any type of media format and hardware models?
No, the supported transition effects may vary depend on single- or multiple-screen applications and will have different performance according to media type and resolution. Below is a basic guideline:
Fade in/out (MS only)
5. What can I do if the display resolution is not listed in WCM Playlist Settings Dialog?
If the resolution you use is not in the list, choose the resolution with the same proportion. For example, if you would like to choose 1920x1200 but it’s not on the current list, choose 1440 x 900 instead. The result will be the same as making a playlist with 1920x1200 resolution. Or use multiple screens to create a playlist for the special resolution, e.g. using 2 screens with 800x600 resolution to create a playlist with 1600x600 resolution. If you can’t find a resolution with proper proportion for your display, create a playlist with a similar proportion and add a zone with the exact proportion needed. Set the zone at the top left and edit the content within the zone to fulfill your specific resolution requirement.
6. Is there a way I can fix the proportion of zone to drag and adjust the zone size easily?
Yes, just double click the zone to launch the Zone Attribute dialog first, and then click the Lock icon to lock or unlock the proportion of the zone.

In general, this service is enabled by default for Windows Server or DT Research’s Edge Server, but not for other systems used as WCM server. Please follow the instructions below to enable this function on your WCM server so players will be synchronized automatically or manually with publish server. Please refer to How to enable NTP Server in Windows Time service
3. The DT Research digital signage solution provides edge server but how to evaluate if edge server is required for my digital signage network?
The edge server is designed for the scenario that many players are installed at one location and play the same content. With an edge server allocated at each location, users can utilize the bandwidth between each server and central WCM server to optimize efficiency. The edge server may not be useful to enhance the efficiency and reduce utilized bandwidth for your signage network design for the following scenario:
1. There are just very few players at each location.
2. The content played on each player at the same location is not the same.
Besides, DT Research offers edge server as a solution which integrates hardware and software in one box rather than software installation package only.
4. How do I map a shared library to a network drive?

, and follow the steps to map the Share Library.
F. Remote Management:
1. How to set automatic power on/off for the signage players? Can I schedule power on/off for each individual player?
The Power Management function provided by WCM is through RTC function. When you set the power on/off schedule for a group, make sure the players in the group are powered on so that the RTC settings can be sent to the players. Power Management function in WCM is limited for Group only. If you need to power on/off each player with different time frame, arrange the players in different groups.
WCM also provides remote WOL (Wake on LAN), Restart and Power Off function. Refer to the picture below. There are no schedule settings for WOL, Restart or Power Off. These commands will be executed immediately and one time only.
2. If I don't want to have an interval between power on and off, can I schedule “reboot” for the signage players every day automatically?

4. If my media files are very large, how do I know if my signage player has enough disk space? Will WCM player automatically clean the disk space?
Yes, WCM has the Smart Cleaner design so the player will follow the below guidelines to clean low priority files to make sure there will be enough disk space all the time:
1. The media files included in the expired schedule only will be deleted from the player.
2. The media files not included in any current schedule will be deleted from the player.
3. After steps 1 and 2, if there is still not enough space, the media files not included in the current schedule will be deleted from the player.
4. If there is still not enough space, the player will report an error message to the System Manager. It is suggested that you to use larger storage to ensure your player can playback smoothly.
1. What should I do if 8my player OS is corrupted and cannot boot into Windows?
If your player disk is larger than 32GB, it comes with a backup OS. You can reboot the system, selecting PE partition. After booting into PE, you will find an option to restore the OS. After the system is restored, please register the player again. If the disk space is less than 32GB or the whole disk is crashed and it can't boot into PE, please contact your sales agent to get a recovery OS image. You may also refer to information on the Recovery page for reference: http://www.signage.dtri.com/products/WCM/recovery.html
