Table of contents
With the increasing prevalence of workflows involving multiple computers, monitors, and high resolutions, the demand for DisplayPort KVM switches is rising rapidly. The key technical challenge is ensuring stable switching without compromising high bandwidth and high refresh rates. Building on years of experience in video switching technology, TESmart has developed a complete series of DisplayPort 1.4 KVM switches to address these industry-wide challenges and enable a seamless multi-device experience.
1. DisplayPort KVM switches: Basics and current state of the art
A DisplayPort KVM switch allows you to control multiple computers using a single keyboard, mouse, and monitor. This simplifies desktop cabling and significantly optimizes workflows with multiple devices.
Unlike HDMI, DisplayPort requires higher bandwidth and processes more complex EDID information. This leads to the following typical problems with many conventional DP KVM switches:
- Low availability and limited selection on the market
- Faulty EDID emulation: Many switches cannot maintain the monitor's EDID information consistently during the switching process. This results in the window size and position being reset, or the entire window arrangement being disrupted.
2. The advantages of TESmart DisplayPort KVM switches
TESmart's DisplayPort 1.4 series meets the demands of modern setups with multiple monitors, high resolutions, and high refresh rates. It ensures compatibility and stability even in bandwidth-intensive applications such as... 4K, 8K and VRR.
With a DP-KVM switch from TESmart, you benefit from:
- Permanent EDID emulation: Thanks to our technology, the GPU recognizes the monitor as permanently connected, even during screen switching. The result: Windows are no longer reset or rearranged.
- Increased efficiency: Optimize your workflows when using multiple computers simultaneously.
- Simplified workplace: Significantly reduce cable clutter on your desk.
- Full performance: Ensure smooth operation with high resolutions and refresh rates without compromise.
Therefore, these switches are the ideal solution for designers, developers, gamers and all professional users who work with multiple systems at their workplace.

6. Frequently Asked Questions (FAQ)
No. A high-quality DP 1.4 KVM switch (like the TESmart DP series) fully supports 144Hz. The crucial factors are sufficient bandwidth (DP 1.4 offers up to 32.4 Gbps) and proper EDID emulation to prevent the refresh rate from dropping to 60Hz.
The temporary black screen is caused by the monitor rereading the EDID. A KVM with true EDID emulation (like the DKS202-M24/MC24 series) ensures that the GPU continuously detects the monitor, preventing the window layout and screen arrangement from being reset when switching between displays.
This depends on the bandwidth and the EDID implementation of the KVM. The TESmart DP 1.The 4 series fully supports VRR and Adaptive Sync, which is why it is highly regarded by gamers.
A DP-KVM is generally better because it offers:
- Higher bandwidth
- Higher refresh rate support
- Improved compatibility with G-Sync/FreeSync
For 4K 144Hz or 8K setups, DisplayPort is the recommended choice. However, it depends on your device:
- PC gamers → DisplayPort 1.4 (better high refresh rate + VRR)
- Console gamers → HDMI 2.1 (native for PS5/Xbox Series X)
- Multi-PC/High-frequency environments → DisplayPort 1.4 is strongly recommended
Yes. DisplayPort is a cross-platform standard. TESmart DP-KVM switches work reliably with macOS (including M1/M2/M3 chips), Windows, and Linux, and support seamless keyboard and mouse switching across all systems.
That depends on the KVM's USB hub. TESmart DP models use USB 3.2 Gen 1 (5 Gbps), which is fast enough for the following:
- Webcams
- USB microphones
- Graphics tablets
- External SSDs
This is significantly faster than older USB 2.0 KVM devices.
High-quality DP KVM switches generally work perfectly with NVIDIA and AMD GPUs. The important factors are:
- Sufficient bandwidth
- Stable EDID handling
TESmart DP models are frequently used with graphics cards of both brands.
Yes. It's an excellent combination. You can set up:
- PC 1: Gaming
- PC 2: Streaming/Encoding
Then seamlessly switch to a monitor, keyboard, and mouse. With TESmart MC series models, you can even transfer files between systems.
Yes – provided the KVM offers:
- Full-time EDID emulation
- A stable DP 1.4 signal path
