sorry, i own lumia phone, ican connect anytime, without chromecast, i need for my computer and chrome cast can't get the job done like the Microsoft wireless adapter

There is nothing that you can do with Microsoft buying a phone line and just killing it. They helped to kill Miracast and WiDi. We hardly stream from our iPhones to our NVidia Shield, unless it is something that cannot be brought up on the shield.

The fact that updating the video driver is still not going to solve anything. The iPhone 6 with the 11 iOS Beta has actually made it a true competitor to the Android OS lines.

Microsoft has locked their phones down so hard, that you cannot even side load anything on them. Because MiraCast and WiDi have been killed off for in favor of the Google Chromecast tech that is multi-platform, is what you are seeing everything heading towards as Microsoft keeps killing off product lines that they see a loss, when it was the OS platform that caused them to lose.
Playcast will be your best bet for your phone. Your request appears to be from an automated process

If all you want to do is put the computer's display on the tv, then just plug a vga or hdmi cable into the tv.

First, you are going to have to update your Display Adapter to one that supports Miracast. Then you may also have to upgrade the WiFi adapter to support Miracast as well.

Both your video card and network card (WiFi adapter) must support Miracast.

Exactly!

This is quite simple: To cast from PC to a Miracast display, both your PC's video adapter and wireless network adapter need to support Miracast / WiDi (wireless display). Miracast Wireless Standard was announced in September 2012, and almost immediately both display adapter and WiFi adapter manufactures started to support it. A rule of thumb is, if your PC came with pre-installed Windows 8.1 or later operating system, and it has integrated WiFi, it and its devices are new enough to support Miracast.

As mentioned earlier, it's not enough that your display adapter supports Miracast. WiFi is also required as can be easily seen in following two screenshots. As long as I have my laptop's WiFi adapter enabled (it does not have to be connected to wireless network, just enabled), I have the option to connect to wireless display:



If I disable my WiFi adapter, Miracast is no longer supported and Connect to a wireless display link will not be shown. My display adapter still supports Miracast but as it needs WiFi, too, I can't cast to wireless display:



I understand what OP wants, Miracast is practical. For instance in my case it's the only way I can use three displays on my laptop. In screenshot I am typing this reply on laptop's own display in the middle, streaming today's breakfast TV from my greatly missed native Finland on Miracast display (Smart-TV with a Microsoft Wireless Display adapter) on left, leaving the HDMI connected external monitor on right for running Hyper-V virtual machines, computer maintenance and so on:



What OP needs, assuming the display adapter supports Miracast, is a WiFi USB dongle that also supports Miracast.
