 ## Known issues and limitations
 * The actual frame rate of the image received via HDMI will depend on the network bandwidth, resolution and the load on the Raspberry Pi. This is usually **~24-28 FPS for 1080p over LAN**.
 * There may be **compatibility** issues with some motherboards (such as **HP** or **DELL**) which are the same as those that exist with PiKVM V2. Not everything is perfect, but if you have already used PiKVM V2 - our new V4 will work great and please you. If there is no image from the BIOS, you can fine-tune the HDMI settings, but it is possible that the Mass Storage devices will not be available in the BIOS.
