Turn on the SmartEDID feature of Pro Capture HDMI 4K Plus LT by editing the register key

Run "regedit" on Windows to open the Registry Editor. Move to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ProCapture\Pro Capture Card Name\Board X, Channel X. Double-click EDIDMode, select the Hexadecimal base and then fill Value data with one of the listed values you want: 1: Turn off SmartEDID. 2: Keep last: keeps to use the same EDID as used for the last time. 4: Add audio: the video source won't output audio when the LOOP THRU interface connects with a monitor that doesn’t support audio input (such as monitors only with DVI or VGA interfaces). In this case, you need to turn on the "Add audio" feature to enforce the source to output audio. 8: Limit pixel clock: if the pixel value of loop-through device goes out of the range that the capture device permits, the capture device will lower the pixel value to ensure successful capture. C: Turn on the "Add audio" and "Limit pixel clock" feature at the same time.

Minimum bandwidth requirements for multi-channel video capture

When multiple channels of video are being captured with Magewell capture device, it is necessary to ensure that the transmission bandwidths of the capture devices and the computer's bus (PCIe or USB bus) are sufficient for the total data of multi-channel video streams; otherwise, frame drop will occur. The maximum transmission bandwidths of PCIe interface and USB interface are: PCIe x1 Gen 2: ~400MB/s PCIe x4 Gen 2: ~1600MB/s Note: Although Pro Capture HDMI 4K, Pro Capture AIO 4K, and Pro Capture DVI 4K Capture cards use the PCIe x4 Gen 2 interfaces, their actual transmission bandwidths are only ~1200MB/s. USB 3.0 bus: ~400MB/s USB 2.0 bus: ~50MB/s When capturing multi-channel video streams, you can refer to the following table to select the video capture format.
