VDI Frequently Asked Questions

Log In & Log Off (3)

What is the username/password/domain of VDI?

  1. Username/Password: Your Windows account/password
  2. Domain: Your site Domain

How to log off VDI?

Double click Log off icon on the desktop to log out from VDI. VDI will automatically log off after 4 hours of inactivity.


Saving & Printing (4)

Can I save my individual VDI profile and preferences from one session to the next?

No, individual profiles cannot be stored at this time. Due to space limitations and security concerns, virtual desktops are discarded after each VDI virtual session ends.

How and where do I save my work in VDI?

To ensure your work is retained after you log off the virtual machine, please save your work to the U: drive rather than the virtual desktop itself (the C: drive). Also, please save frequently—at least every 25 minutes or so—because your session will time out or log you off automatically after 2 hours of inactivity. Make sure you save your work frequently to avoid losing it!


  1. Double click MappingHomeDrive icon from desktop to enable your U: drive.
  2. Go to HQ_Public and find your U: drive.

How do I print from VDI?

In general, printing to a local printer from the VDI is unsupported. Because of the vast number of printers in the market, it is not feasible for the VDI to work with every type of printer.

I lost my work when I logged off the VDI. What happened?

Anything you save on the VDI virtual machine during your session will be lost when you log off, so you should always be sure to save your work to U: drive before you log off.

How do I switch my display protocol between RDP and PCoIP?

  1. In the connection window when you are first connecting to the VDI, click on the white, downward-facing, triangular arrow to the right of Mxx_Public.
  2. In the dropdown, select “Display Protocol.”
  3. Select Microsoft RDP or PCoIP. Ensure RDP is selected if you can’t access VDI via PCoIP.
  4. Select Connect.

Your connection setting display protocol will remain whatever you chose in the future unless you change it. (See also what is the difference between RDP and PCoIP?.)

I get a black screen with no desktop or icons when I log in VDI. What should I do?

Your network environment has some limit by ISP or not stable, please switch protocol to RDP (see also how to switch your connection between RDP and PCoIP) than try again. If this doesn’t fix it, contact IT Global Service Desk, call #36500 from your local site.

The VDI & Your Local Computer (4)

Can I access my computer’s local drive when I’m using the VDI?

No, you can’t access your local drive while using the VDI.

Can I change the resolution or screen size of the VDI?

No. This feature is not currently supported. But you can change the window size.

Can I copy and paste between the VDI virtual desktop and my own computer?

Yes, you can successfully copy and paste from local to VDI, but you cannot copy and paste from VDI to local.

How do I switch from the VDI virtual desktop back to my real desktop?

Your remote desktop connection is full screen by default. To change this so you can see your local computer too:

  1. On a Windows computer:
    1. Simply double-click on the toolbar at the top of the screen that says the name of the VDI build, which will shrink the virtual desktop window so you can access your own computer.
    2. You can then drag the VDI’s virtual desktop window to your desired size.
    3. Or, you can just press the Windows key on your keyboard, next to the left Control key, which will also bring your own computer desktop to the front and minimize your virtual session. (Repeat to switch back.)
  2. On a Mac: Go under View in the toolbar at the top and select Full Screen.

General Mediatek VDI Questions (3)

Can everyone use the VDI?

MediaTek’s staff, consultant, outsourcing contractors, or vendor are able to use VDI.
But you have to apply Mobile service first.

What is the difference between the RDP and PCoIP protocols in VDI? Why do I choose one over the other?

The primary advantage of PCoIP is speed and display quality. The primary advantage of RDP is that common protocol on some restrict network is available. Neither is “better”; they are just different:

  1. Use PCoIP if any of the following are true for you:
    1. You want to display better quality graphics, video, and sound.
    2. If bandwidth is not a problem because you are on a high-speed connection.
  2. Use RDP if any of the following are true for you:
    1. You don’t know your network quality, set RDP is better than PCoIP
    2. If graphics, video, and sound quality are not an issue.
    3. If you have limited bandwidth because you are on dial-up or a slow DSL connection.

Your connection setting display protocol will remain whatever you chose in the future unless you change it. See also how to switch your connection between RDP and PCoIP.

Where can I use VDI?

You can access the software you need via VDI from home, or from anywhere else with internet connection!
