Some compatibility issues with Merchant
Not everyone will be able to use Merck. I had trouble connecting my laptop using Miracast because it requires the use of Intel HD Graphics and since I have a dedicated graphics card for it in my system I can’t use it.
Your desktop PC will also need to use a wireless connection to connect to the laptop. Since I use an Ethernet connection and don’t ship to Wi-Fi, I have to use a wireless adapter to use my laptop as an additional display.
