Scaling
Use the Output Scaling submenu to specify the best match between screen size and
user requirements. Neither transparent conversion nor conversion with scaling alters
the refresh rate!
Output Scaling sub-menu
It is not possible to alter the refresh rate during conversion! If your source
is 50Hz or 75Hz VSYNC – please make sure that your flat screen is able to
display a picture with this refresh rate. Otherwise, please select 60Hz
refresh rate in the settings of your graphics card.
Please note that scaling of a 16:9 resolution to a 4:3 resolution will result
in an incorrect aspect ratio of the displayed picture.
If your input signals are DVI-D, and you use scaling for downsizing your
picture, there are limits for the scaling factor: The pixel clock of the input
signal needs to be at maximum 1.9x output pixel clock.
This means:
Output 800x600
max. input resolution 1024x768
Output 1024x768
max. input resolution 1680x1050 (Reduced Blanking)
Output 1280x1024
each input resolution possible
If your input signals are VGA, there are no restrictions in respect to down-
or upsizing your picture!
No scaling: picture displayed in original
size, output refresh rate = input refresh rate
Choice of 3 output resolutions for scaling
(output refresh rate = input refresh rate)
800x600, 1024x768, 1280x1024
