4 Port DisplayPort Video Switch with Audio & IR Remote Control

Questions & Answers

Everything is hooked up but nothing is working. What should I do?
When you troubleshoot issues with a video splitter, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue: Video cables Video switch Video source (such as a DVD player or computer) Video destination (such as a monitor or projector) Note: When you are testing setup components, you should avoid using video adapters. For example, if you are converting a VGA source to HDMI for use with an HDMI switch, you should use an HDMI source when you test the components. To test your setup components, try the following: Use the cable, video switch, video source, and video destination in another setup to see if the problem is with the components or the setup. Use a different cable, video switch, video source, and video destination in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup. When you test your cables, it is recommended that you do the following: Test each cable individually. Use short cables when you are testing. When you test the video source and video destination, it is recommended that you do the following: Remove the video switch from your setup and test to make sure that the video source and video destination work together without the video switch. Test to make sure that the video source and video destination work together at the resolution that you want to use. Note: In order for your setup to work properly, the video source, switch, and destination all need to support the resolution that you are using.

How can I connect this DisplayPort output to a VGA, DVI, or HDMI display?
A DisplayPort output can be connected to VGA, DVI, or HDMI displays using the appropriate adapter or video converter. The required adapter may be passive or active, depending on whether the DisplayPort source supports DisplayPort Dual-Mode (DP++). Explanation: This device outputs DisplayPort video signals. If the display or video destination uses a different video interface, a DisplayPort adapter or converter may be required. The type of converter depends on the capabilities of the DisplayPort source: Passive adapters require a DisplayPort Dual-Mode (DP++) source. Active adapters work with both standard DisplayPort and DisplayPort Dual-Mode (DP++) sources. Common conversion options include: VGA: Requires an active DisplayPort to VGA converter because VGA uses analog video signaling and DisplayPort outputs digital video. DVI: Can use either a passive or active DisplayPort to DVI adapter, depending on source compatibility. HDMI: Can use either a passive or active DisplayPort to HDMI adapter, depending on source compatibility. Before selecting an adapter, verify whether the DisplayPort source supports DisplayPort Dual-Mode (DP++). This information is typically available in the device specifications or documentation. For the best compatibility: Use the fewest possible adapters and converters. Verify the required resolution and refresh rate. Confirm whether an active or passive adapter is required for the specific DisplayPort source. For more information about DisplayPort Dual-Mode (DP++) and active versus passive adapters, refer to the following FAQ: https://www.startech.com/faq/DisplayPort_Converter_DP_Multi_Mode .

How can I connect a VGA, DVI, or HDMI video source to this device's DisplayPort input?
This device features a DisplayPort input. If your video source uses VGA, DVI, or HDMI, you can connect it by using the appropriate video converter. The required conversion path depends on the video output available on the source device. Explanation: DisplayPort inputs require a DisplayPort signal. Video sources that use VGA, DVI, or HDMI typically require signal conversion before they can be connected to a DisplayPort input. Common conversion paths include: VGA source: Use a VGA-to-HDMI converter, followed by an HDMI-to-DisplayPort converter. DVI source: Use a DVI-to-HDMI adapter or cable, followed by an HDMI-to-DisplayPort converter. HDMI source: Use an HDMI-to-DisplayPort converter. Because DisplayPort and HDMI use different signaling technologies, a simple passive adapter is generally not sufficient when converting from HDMI to DisplayPort. An active converter is typically required. For the most reliable installation: Use the fewest possible adapters and converters. Verify that all converters support the required resolution and refresh rate. Confirm that the converter supports the correct signal direction (source to display). If multiple video outputs are available on the source device, choose the connection type that requires the fewest conversions to simplify the installation and maximize compatibility.

What DC barrel connector power plug types do StarTech.com products use, and what are their dimensions?
StarTech.com DC barrel connector plug types are defined in the “Plug Type” field of the technical specifications, using a letter code that specifies the connector’s outer diameter (OD) and inner diameter (ID) in millimeters for power adapter compatibility. Explanation: In StarTech.com technical specifications, the “Plug Type” field is a standardized identifier for the exact DC barrel connector size required to power a product. Each plug type is assigned a letter code that corresponds to a specific combination of outer diameter (OD) and inner diameter (ID), measured in millimeters. Common DC barrel plug type dimensions Plug Type OD ID A 2.35 mm 0.7 mm B 4.0 mm 1.7 mm C 4.75 mm 1.7 mm H 3.4 mm 1.3 mm L 5.0 mm 2.5 mm M 5.5 mm 2.1 mm N 5.5 mm 2.5 mm The DC barrel connector plug type must match both the outer diameter and inner diameter exactly. A mismatch between the StarTech.com product requirement and the power adapter connector can prevent proper fit or stable power delivery, which may result in device startup failure or intermittent operation. The plug type defines only the physical connector size. The plug type does not define electrical power requirements such as voltage, current, or polarity. The power adapter used with a StarTech.com product must match the product’s specified electrical requirements. Using an incompatible power adapter can cause device malfunction or permanent damage. This standardized DC barrel connector plug type system enables IT professionals and procurement teams to verify connector dimensions, ensure power adapter compatibility, standardize hardware deployments, and identify the correct replacement power supply for StarTech.com products.
