The refresh rate of your display will directly influence the prediction and smoothness of AnimPlayer’s playback.
AnimPlayer is able to playback with correct speeds for Film, PAL and NTSC independent of the refresh rate of your monitor, but this may result in playback which is not particularly smooth and precise.

By default AnimPlayer will warn you if this will happen. For certain technical reasons, very smooth playback must be synchronous to your display’s refresh rate. This means on the other hand that for each refresh rate setting, only certain discreet playback speeds for smooth playback are available.

Unfortunately some LCD monitors only support one dedicated refresh rate (in general 60 Hz).
Choosing the right Refresh Rate
On multi-monitor configurations AnimPlayer can synchronize only to one monitor at the time and it is recommenced to configure all monitors with the same refresh rate to minimize display artifacts.
If this is not possible please keep in mind that the 6 presets for smooth playback are different for each monitor.
You should choose the refresh rate based on the nature of standard you are working with. Below are the recommend refresh rates for each standard.
| Film | PAL | NTSC | |
| speed | 24 fps | 25 fps | 30 fps |
| refresh rate 1 | 72 Hz | 75* Hz | 60 Hz |
| refresh rate 2 | 120 Hz | 100 Hz | 120 Hz |
If you plan to use HD material please choose the lower "refresh rate 1" for best playback performance.
How to set the Refresh Rate
Open the Display Properties Dialog and press the [Advanced] Button in the bottom right corner to open a new dialog. Now select the [Monitor] tab.

Please note that not every monitor supports each recommended refresh rate. Some higher rates are only available on lower screen resolutions.
Also note, some graphic drivers also provide their own utilities which give faster access to the refresh rate settings.
Warning!
If you are still working on a CRT computer monitor, a refresh rate lower than 75 Hz is not really healthy for long term usage. You may get tiered sooner or a headache.
