D: Advanced Settings - Retro Games THEC64 User Manual

APPENDIX D
ADVANCED SETTINGS
There are some settings on THEC64 that are a little more advanced in regards to what
they do. These include Video output, Audio scaling and NTSC or PAL computer model
settings. Read this appendix when you can't get a program to run the way you think it
should be.
60 HZ OR 50 HZ
If your connected HD display can accept a 50 Hz image, you will see Video output
settings during the initial set up process for THEC64. You can choose between 60 Hz
(the default) or 50 Hz.
If your current HD TV or monitor can display a 50 Hz signal, then Video output
options appear when you first switch on THEC64 as part of the initial set up. If your
HD TV or monitor cannot display at 50 Hz, then this screen does not appear and
THEC64 automatically uses 60 Hz.
WHY CHANGE THIS SETTING?
An original North American C64 computer outputs at a refresh rate slightly less than
60 Hz. A European C64 outputs at a rate slightly more than 50 Hz.
In comparison, THEC64 locks to the HDMI rate of exactly 50 Hz or 60 Hz depending
on the Video output setting, so that it produces super-smooth and tear-free graphics
when running programs on a modern HD display. Regardless of the video output
setting, THEC64 ensures that programs believe they are running at original C64 PAL
or C64 NTSC speeds, as appropriate.
A C64 PAL computer will run faster when the Video output is set to 60 Hz. An NTSC
C64 computer will run slower when the Video output is set to 50 Hz. As you would
expect, a C64 PAL computer runs at almost exactly the right speed when the output is
