Set [Start]-[Control Panel]-[Adjust screen
resolution]-[Make text and other items larger
or smaller] to "Smaller - 100% (default)".

If [Priority] of [JPEG Streaming] is set to the
"Framerate" mode, the frame rate requested by
the clients are kept, but the maximum number of
streams is reduced.
The frame rate of displayed videos is low.
N If the Built-in Viewer is in use, check the
Built-in Viewer settings.
If the network has a narrow bandwidth, the frame
rate will be limited.
If [Priority] of [JPEG Streaming] is set to the
"Client Number" mode, and if the number of
streaming requests increases, the images are
distributed at a frame rate lower than the preset
rate.
If the distribution capability is exceeded, images
are distributed at the lower frame rate so that the
upper quantity limit of distribution data is not
exceeded.
