8K Bi-Directional DisplayPort Switch DP 4K@144Hz 2in1out Switcher, 1 in 2 Out for Switching Video Signals Between Two Screens for one Computer (2 in 1)

Important Notice: 1. This DP SWITCHER is mainly used as a switch, so when used as a 1 in 2 out display, press the "Select" button to switch between the two displays. Two monitors cannot display simultaneously. 2. You need to use a standard DP1.4 cable with a length not exceeding 3M for this switch to function at its best, otherwise it may flicker or the screen turn black on some devices with poor signal. 3.If the screen flashes, it is because the DP cable is too long or of poor quality. Please replace with a better or shorter DP cable. This product does not have signal amplification function, and 8K signal requires a larger bandwidth. If the DP cable is too long or of poor quality, signal attenuation will be severe, and the screen will flicker or turn black. 4.Due to system limitations, there may be compatibility issues between the HP ZR30W and certain graphics cards. Do not connect the HP ZR30W monitor. 5. Due to the need for computer signals to communicate with the product before being transmitted to the monitor, there will be a delay of several seconds after connection, and the delay time will also vary depending on the monitor. This is a normal phenomenon.
