Looking for a DP 1.4 KVM Switch with EDID? Check Out This Game-Changer!

When using a standard DP KVM switch, you might run into a variety of frustrating display issues, such as no image, incorrect resolution, frequent disconnections, or even the inability to support high refresh rate monitors. These pesky problems often come down to one unsung hero: EDID (Extended Display Identification Data).
TESmart's DP 1.4 KVM switch is the ultimate solution to these challenges, offering smooth switching, high compatibility, and a seamless display experience. Let’s explore some common KVM issues and see how TESmart tackles them effortlessly with its advanced EDID technology.

Reasons Behind Common Issues with Normal DP KVM switches

EDID plays a vital role in KVM switches, as it acts like a business card that provides essential details about the connected display device. This information includes the manufacturer, product ID, serial number, production date, monitor size, supported resolutions, refresh rates, and more.
In a DP KVM switch setup, where multiple devices share a single display, the EDID ensures that each connected video source can accurately communicate with the monitor through DisplayPorts and maintain the screen integrity. However, users frequently encounter compatibility and display-related problems when using normal DP KVM switches. Here are some common issues and their causes with those DP KVM switches.
  • No Video Output
One of the most frequent issues with those DP KVM switches is a complete lack of video output after switching between computers. They do not have the necessary hardware or firmware to properly read and transmit EDID data. They need proper EDID emulator to ensure that the correct EDID data is relayed to the source device.
No video output
  • No Video Display After Switching Between Devices
This issue commonly occurs when switching between two different source devices on a DP KVM switch, and the display fails to show video from the newly selected device. It’s because the Hot Plug Detect (HPD) signal is missing. While most modern DisplayPort devices and hosts implement HPD functionality, not all products guarantee this feature. Certain low-end or specialized devices may not have been designed with HPD in mind.

*Hot Plug Detect (HPD) is a signal mechanism in display interfaces like HDMI and DisplayPort that detects when a display device, such as a monitor or TV, is connected or disconnected from a source device, like a computer or gaming console.
No Video Display After Switching Between Devices
  • Resolution Mismatch Between Source and Display
Another common issue is when the resolution of the display does not match that of the video source. Sometimes, when the computer fails to recognize the EDID of the monitor through the DP KVM switch, it defaults to a low resolution. Even if the EDID is recognized, some graphics card drivers may limit the output resolution to a default like 1024x768, which might not match the monitor's native resolution through the KVM. These are most because of the narrow compatibility of those DP KVM switches.
Resolution Mismatch Between Source and Display
  • Frequent Signal Dropouts or Flickering
DP KVM switches are also prone to signal dropouts or flickering, which disrupt the user experience. That may be the long or low-quality DisplayPort cables those KVM offers, which can degrade the video signal, causing flickering or loss of signal.
  • Failure to Support High Refresh Rates or Advanced Display Features
Gamers and professionals using high-end monitors with features like 144Hz/240Hz refresh rates, 4K/8K resolution, or VRR (Variable Refresh Rate) often encounter compatibility issues when using normal DP KVM switches. Many standard KVM switches (DisplayPort standards 1.4 or lower) do not support the bandwidth required for 4K at high refresh rates or advanced features like VRR.
  • Multiple Display Connection Issues
When connecting multiple displays to a single video source via a DP KVM switch, users may experience resolution conflicts or connection failures. That’s because most DP KVM’s built-in in-and-out module solution is not good enough, leading multiple signal exchanges during source switching. When connecting multiple displays to a single video source via a DP KVM switch, the inefficient switching mechanism may cause the video source to read the wrong EDID from one display, leading to mismatched resolutions or a lack of video output on secondary monitors.

 

How TESmart’s DP 1.4 Switches with EDID Fix It

EDID acts like a business card for your display, holding key information such as the manufacturer, product ID, supported resolutions, and refresh rates. It ensures smooth communication between video sources and displays.
Without EDID, mismatched resolutions can cause issues like black screens and flickering. By sharing its capabilities, a monitor uses EDID to help video sources deliver the right signal for the best viewing experience.
TESmart’s DP 1.4 KVM switches equipped with advanced EDID technology effectively address the common issues associated with standard DP KVM switches.
  • Industry-Leading 99% Monitor Compatibility
TESmart's DP 1.4 KVM switches are equipped with advanced EDID emulation 2.0, ensuring seamless display even when switching between devices. This technology supports high-resolution displays, including 4K@144Hz/240 Hz and 8K@60Hz. Users can expect no black screens or flickering during transitions, providing an optimal viewing experience.
  • Superior Switching Speed
Unlike other DP KVM switches without EDID support, which often lead to black screens or resolution mismatches, TESmart's KVM keeps the EDID data consistent, eliminating the need to re-read display information.
The integration of EDID emulation 2.0 also allows TESmart's KVM switches to maintain a constant online signal from the computer sources. This ensures that the EDID data remains unchanged, which eliminates the need to re-read display information during switching. As a result, switching speeds are significantly enhanced, achieving response times of less than 3 seconds.
  • Support for Multiple Displays
With the capability to emulate various advanced monitors, TESmart’s DP 1.4 KVM switches can manage multiple display connections more efficiently. The built-in modules allow for smooth transitions between different resolutions 1080P/2K/4K/8K and refresh rates 60Hz/120Hz/144Hz/240Hz, ensuring that each connected display receives the correct EDID.
TESmart’s DP 1.4 KVM switches resolve common EDID issues found in standard DP KVM switches, providing exceptional compatibility, rapid switching, and advanced display capabilities. We are confident to say that we are the only DP 1.4 KVM switches on the market that offers an almost entirely online signal.
