| Q1. |
Why the projection frame rate is slow? |
| A. |
MirrorOp needs the sender to encode screen images and the network (especially wireless network) to transfer massive real-time data to the receiver.
• For the sender: a dual core PC (excluding Atom processors) or Mac with NVidia or ATI graphic hardware is required to encode the screen images in 30 FPS (Frame Per Second) speed. However, if you still feel the FPS is not high enough, you can:
- Lower the PC screen resolution by choosing:
Menu >> PC Screen Resolution >> Small
- Use better media players, such as PotPlayer V1.5 and above
- Quit unused applications
- Use a faster PC with Windows Experience Score higher than 3.5 (4+ recommended)
• For the WiFi network, you can:
- Change to use 802.11n WiFi
- Move your Laptop closer to the receiver
- Disable the “Minimum Power Consumption” option from the “Advanced Tab” in your WiFi Network Adopter Property setting
- Set the Projection Quality to “Normal”
- Lower the PC screen resolution!

Why I see a horizontal split line on the TV side when watching video? |
| Q3. |
I use my Windows 7 and my own video player (such as Media Player Classic), why I cannot see the video (only see black screen) on the TV? |
| A. |
To support more Windows PCs with reasonable performance, by default, the Aero Glass effect will be turned off to increase the screen capture speed. However, some video players (such as Windows Media Player) have some compatibility issue running on this mode. Followings are options you have:
- If you are using Windows Vista or Windows 7, use Media Center
- Use better media players, such as PotPlayer V1.5 and above
- Enable the “Advanced Screen Capture” option from the main menu. However, the frame rate may drop!

| Q4. |
My PC desktop can be shown on the HDTV. However, the edges of my desktop were cut so that I cannot even see my taskbar! |
| A. |
Although HDTVs have high resolution to show PC desktop images, some of them will do "over-scan" for you to see bigger images for video watching. To correct this problem, two options are available:
- Turn off the "Over-scan" setting of your HDTV. You may need to consult to the TV's user's manual to see if this setting is available. If not:
- Use the "TV Offset Compensation" function from the main menu of the sender application to correct this problem. However, the projection frame rate may be dropped because the PC's CPU needs to scale the original desktop images down before transmit to the receive device.
|
| Q5. |
Why the picture quality of the desktop images shown on my HDTV is not as good as the original one? |
| A. |
To reduce the bandwidth requirement, we adopt lossy compression method. Hence the quality of the projected images may slightly lower than the original one. To see better quality, you can set the Projection Quality to “Best” from the main menu. However, you may need to choose a clear WiFi channel, or use an Ethernet cable to provide enough bandwidth to achieve high frame rate. |
| Q6. |
Why I cannot see tip windows from my task bar? |
| Q7. |
Why I cannot see the icon moving when I drag my desktop icons from the TV side? |
| Q8. |
Why some of my applications (especially video players) fail to launch after I run the sender application? |
| A. |
To support more Windows PCs with reasonable performance, by default, the Aero Glass effect will be turned off to increase the screen capture speed. By turning the Aero effect (or Graphic Acceleration) OFF, some application that rely on this feature may fail to launch. To correct this problem, you can:
- Enable the “Advanced Screen Capture” option from the main menu.
Side effects:
- You local mouse cursor may blink from time to time.
- The projection speed may be slower!
|
| Q9. |
The aspect ratio of my screen is distorted on TV! I look too fat! |
| A. |
The projected image is identical to the PC screen. However, due to different aspect ratio in different resolution settings on PC (4:3 or 16:9), the aspect ratio may be altered by the TV to fit to screen. Please look for options on your TV such as scaling, fit-to-screen or aspect ratio to change how the PC signal is fitted to TV, or change your PC resolution to the same aspect ratio as your TV screen (mostly 16:9 on new flat TVs). For example, select 1280 x 720 on your PC for original aspect ratio on a 16:9 flat TV.
|
| Q10. |
When I play a movie from a blue ray disc on my PC, I cannot see the movie (only see black screen) on the TV? |
| A. |
In Windows and Mac environment, some content protection mechanism is implemented to protect high definition video content from being “captured”. This is done on purpose to keep the “protected contents” from been reproduced, and is a limitation of similar screen capture technologies! |
