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.
E. WCM Server Upgrade and Management (Time Server & Edge Server):
1. How to backup and restore WCM6 database?
2. What should I do if I'd like to make sure content played on multiple players will be synchronized? Is the Time Server included by default to synchronize multiple players?
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?
Please read the document, 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 WCM6 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 WCM6 is limited for Group only. If you need to power on/off each player with different time frame, arrange the players in different groups.

WCM6 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?
This function is not supported by WCM6 by default. But you may refer to How to make OS regularly reboot to set up your players.
3. Does WCM6 support remote control of LCD screen functions? (Like power on/off, adjust brightness, contrast...etc.)
WCM6 supports the LCD control function but for specific brands and models only. You may contact your DT Research local reseller or our tech support team to check on other screen models. Please refer to WCM6 Player Screen Control for supported models and functions.
G. Player Management:
1. Is there a way that I can hide the message of “ctrl-shift-space to exit player” for my players?

2. Can I change the default speed of Low/Medium/Fast for the Ticker?
Yes, you can modify the ticker speed default value – please find the DTMP.conf from: %appdata%\Roaming\DTRI\WebDT Signage Player\config, open it to search and edit the default value as shown below. The unit of value is pixel. Please be aware that changing the default value to other figure may lead to some ticker shaking issue. You may need to test and preview the results.
< Ticker >
< Speed >
< Fast >300< /Fast >
< Normal >200< /Normal >
< Slow >100< /Slow >

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, WCM6 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.
H. Troubleshooting:
1. What should I do if my 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
2. If I need a longer cable between the display and the signage appliance/multiscreen appliance, what will be the maximum length of cable I can choose?
