Usually the best results in scaler mode are obtained by choosing the highest resolution supported by
your display. If you do not get a picture, or the picture intermittently disappears or blanks, choose a
lower resolution.
Framelock
Framelock is an important option to understand. When Framelock is on, output refresh rate is
matched to the input. This results in a smooth image with no judder. While this is desirable, it may
be necessary to turn Framelock off for the purpose of compatibility or if your game title uses
multiple screen modes (such as a game which uses interlace in the menu screens but progressive
modes during gameplay). In these cases, choose “Off (50hz)” for PAL material or “Off (60hz)” for
NTSC.
In line multipler modes, frame lock is always on and cannot be disabled.
Scaling algorithm
You can use this option to change the appearance of the scaled image. Generally, it is just a matter
of choosing which option you personally think looks the best. For more information on these
options or to use the custom scaling algorithms,
Interlace video and the DExx
Certain retro consoles and computers (e.g Sony PS2, Nintendo Gamecube) output in interlace
modes. These modes send alternating scanlines to the display in each frame and were how standard
definition analogue television was broadcast. To display interlace video on modern displays, it must
be deinterlaced first.
In line multipliaction mode, the DExx can deinterlace content like this with no input lag. However,
the image that is produced tends to exhibit some flickering and combing artefacts.
If the flicker is distracting, we recommend you use the scaler mode and the motion adaptive
deinterlacer. To activate the motion adaptive deinterlacer, follow these steps.
