➢

 

While using multiple units for video wall applications, please enable [Frame Sync] menu under 

[Options]

→

 [Setting]

→

 [Frame Sync] 

→

 [Normal].   

➢

 

The input refresh rate should be the same as output refresh rate so that the system can 

implement Frame Lock to synchronize all the outputs from multiple units. If the input source is 

50Hz with 60Hz output, it is possible to see some synchronization issue. 

26.6.  Call for technical support 

➢

 

User can send e-mail to [email protected] together with as much information as possible.   

➢

 

The following information is required for a swift response. 

- 

Sink device (monitor): type and model number 

- 

Monitor layout or specific application details (shape of video wall). 

- 

GeoBox model No. and series No. 

- 

Detailed timing of signal source and resolution. 

- 

Press [Info] key to get System Information and send the data to us, including input/output 

timing and F/W version. 

- 

The exact nature of the problem. Please be as detailed as possible.   

- 

If possible, please attach the Pictures of the issue. 

➢

 

Usually, we will response with 24 hours (excluding weekends) 

➢

 

Please note that if the machine is sent back for repair, user needs to pay for delivery cost. 

27.  Safety Precaution and Maintenance 

➢

 

Power Supply 

Please connect electric power for all devices in the system from the same Power Distribution Box 

with correct grounding. Open the power after finishing system connection to reduce the risk for 

system damage from high floating voltage. 

➢

 

Working Environment 

Please locate GeoBox in an environment free from dust, moisture and high temperature with good 

ventilation. 

➢

 

Maintenance and Repair 

Apart from what is detailed in User Guide, maintenance should be carried out by competent 

technician assigned by VNS. If GeoBox is physically damaged, it should be returned for repair using 

VNS RMA procedures. If the unit is opened by user, it will lose the right for warranty protection.
