Advanced Video Settings

Some settings are not available for/applicable to every context, click here for details.

RGB color space

Digital RGB video comes in two different color modes. RGB limited only uses video levels 16-235 per color, while RGB full uses the full 8bit range of 0-255.

Color expansion

Older consoles may not make use of the full 24bit of color available in RGB (8bit per color) and use a 15bit or 16bit color scheme. Because the output video is 24bit RGB, for example full white in a 15bit color scheme does not translate to a value of #FFFFFF, but instead #F8F8F8.

PS1Digital can expand the limited value range back to full, so a 15bit white color will be #FFFFFF again.

Settings for RGB color space (limited) are applied after the color expansion

Gamma adjust

Force mode (Firmware < 1.3.0) / Clock adjust (Firmware >= 1.3.0)

Many PS1 games are switching between 240p and 480i video during gameplay. E.g. the game itself runs in 240p, while menues are running in 480i mode. Because the vertical refresh rates of 240p and 480i are not the same, also the refresh rate of the digital video changes. On many TVs this causes the screen to go blank while the monitor/TV resyncs to the video signal.

PS1Digital can prevent that resync by forcing the output video to stay at 240p/480i vertical refresh rate. Because input and output video are no longer in sync when in the forced state, there may be visible screen tearing from time to time.

Starting with firmware 1.3.0, two new modes prevent this screen tearing: vfr-hdmi and overclock

vfr-hdmi and overclock modes only apply to 960p/1080p output resolution.

Auto reset alignment (Firmware >= 1.6.7)


Deinterlacer mode

HQ2x filter

PS1Digital can HQ2x filter the input video while upscaling. HQ2x filter may not apply, if there is no 2x scaling stage, e.g. 640 horizontal input resolution and VGA output.

HQ2x filter stage

When the input to output scaling factor is 4x (320 horizontal input resolutiuon / 960p or 1080p output), you can also configure the order in which the scalers operate.

Settings disabled in certain contexts

Not all settings are available for/applicable to every setting, input video or output video combination.
The OSD shows those settings in red. They still can be changed, but they do not apply in the current context or are set to default values.

The rules are applied in order 1 to 4, so 1 has a higher priority than 2, but they are also cumulative.

1. Force mode is 240p or 480i / Clock adjust is not off

2. Deinterlacer mode passthru and input video is interlaced

3. Input video is progressive

4a. Output video is 960p or 1080p

4b. Output video is VGA or 480p
