Questions in this category have to do with troubleshooting PC issues when using ZvBox. Click on a question to show or hide the answer.

After setting up ZvBox, my computer won’t boot properly. Why?

In all likelihood your computer is trying to boot from ZvBox. That happens because some computers try to boot from a USB drive if one is present, and ZvBox “looks” like a USB drive to the computer. This problem isn’t specific to ZvBox-- it would occur if any USB drive were connected to the computer at startup. Here’s a fix:

  • Start the computer, and early in the startup process use the indicated function key (F1, F2, etc.) to enter the “Setup” menu.
  • Go to the “Boot” section of the Setup menu (note: if there’s no boot section in the Setup menu, open the “Advanced” section of the Setup menu).
  • Find the “Boot Device Priority” section.
  • Change the setup so the Hard Disk Drive is the first priority device in the sequence, for example:

1) HDD
2) Floppy Drive
3) CD ROM
4) Network booting

This will cause the computer to try to boot from the Hard Disk Drive first, and not from ZvBox.

When Zv is transmitting, why is my computer resolution an odd size such as 1190x670?

Zv software has made this adjustment to your desktop to make sure that the entire image is properly displayed on your HDTV. This is known as Overscan Compensation.

Note: To adjust the picture size to better fit your TV, go to ZvBox Manager and select “Launch ZvBox Settings.” Then select “Adjust Picture Size.”

Why is it when I use my laptop with Zv sometimes it transmits to my HDTV, sometimes it doesn't?

Laptops can be finicky about sending anything out of their VGA (video output) connectors, where ZvBox connects to the computer. Consult your laptop user manual to see if anything special needs to be done to enable that capability.

When I try to install ZvBox, why do I get a warning message saying that the software has not passed Windows Logo testing?

Microsoft offers Windows Hardware Quality Labs (WHQL) certification for drivers, effectively giving the driver a seal of approval. If a driver is not WHQL certified, you will see a warning message about it. Some hardware manufacturers choose not to have their drivers WHQL certified, or the drivers can be brand new and not yet certified. It does not mean that the driver is bad, just that Microsoft has not officially certified it. It’s safe to click the “continue” button to install the Zv driver.
