FAQ

Which capture method should I use?  DirectX or GDI?

-The implementation of the DX (DirectX) capture method guarantees that the display's backbuffer is read.  The GDI implementation on the otherhand may or may not pull the captured image directly from the backbuffer.

• What this means is that there are special cases involving hardware-overlay where GDI might not capture what you're seeing on the display.
• Most of the time however, GDI will capture what you are seeing and produce identical image results to using DX capture.

-GDI has a slightly lower memory overhead than the DX capture method.  The DirectX capture needs an additional texture (for quick capture of the backbuffer's contents) to remain allocated in video memory, and the size of that buffer depends on the color depth and resolution of the primary display.

-Both the DX and GDI capture methods in practice have similar performance (due to the bottleneck of transfer through system-memory), yet on some drivers one may run faster than the other.

• Show Performance Stats - option - may be useful in determining which performs best for your PC hardware and usage.

-GDI capture tends to be more reliable for applications running in OpenGL fullscreen mode.

• You may wish to stick to GDI if you run some CAD type software for your lectures.
• DX capture is very reliable for everything run in Windowed mode.

-DX capture has a tendancy to cause more stuttering of the host-system on older hardware.

In summary: Run whichever works best for you and your software.

GDI is the default mode selected because of best hardware compatibility, but DX capture tends to have better software compatibility.

• If you run your programs and have no problems with the GDI capture method, you can just keep using it.
• If you encounter "black boxes" or missing portions of the primary display on the cloned, then switching to DX capture may fix these issues.

I have more than two displays connected to my PC, which monitors will DisplayClone use?

In the case of many displays being connected to a PC, DisplayClone will always clone the "primary" display to the display configured to extend desktop closest to the right of it.

How do I configure my displays that are connected to my PC for DisplayClone?  (in the Windows OS)

Nothing special here like using the Windows built-in Clone-Mode.

• DisplayClone just needs your monitors to be configured as an extended-desktop. (the default mode on connecting a new monitor to your PC)
• You should additionally un-check to show the Windows Taskbar on your extended desktop displays.
