Do all Dell computers support Miracast?

The first question to answer would be, does Dell support Miracast? For a Dell PC, you must ensure that it’s compatible with Intel Wireless Display (WiDi).

This is because the Dell hardware needs the Intel WiDi feature to support Miracast.

Therefore, to use Miracast on Dell computers, it’s essential for the imaging device and the client system to be compatible with WiDi.

For the WiDi technology to function properly, it needs a set of compatible hardware, drivers, and software such as wireless and graphics drivers based on each supported OS.

What else can prevent my Dell laptop connect through Miracast?

At the same time, make sure that you are not using a 3rd party graphic cards like Nvidia or AMD, since that may prevent Miracast to work.

Also note that Miracast uses Wi-Fi Direct, which means, it connects straight from the laptop to the TV when both the devices are in closer proximity. 

So, even if the PC and TV are using the same Wi-Fi network, but your PC is not closer to the TV, Miracast will not work.

Besides, if you are using a 3rd party graphics card, you would need to remove it, because WiDi works only with the integrated Intel video card.

Alternatively, you can replace the wireless card or update the BIOS if you have not recently. Updating the BIOS card may help fix the issue when Miracast and Wi-Fi are not working at the same time.

But if you are using another device that does not support Miracast, you can refer to our complete guide on how to fix the issue.
