Choose an output resolution from these presets. Your selection will also be used for startup.
1280x960 is recommended for NTSC sources, 1280x1024 for PAL.
Use the "Matched Presets" option to switch between the two automatically (see Prefs tab)
If you want to save your customizations, first select a slot for your new preset, then save to or load from that slot.
Selecting a slot also makes it the new startup preset.

ADC Gain (Brightness)Gain +/- adjusts the gain for the currently loaded preset. |
Scanlines only work with 240p sources. They look best with the Line Filter enabled.
Peaking and Step Response are subtle sharpening filters and recommended.
This option keeps the input and output timings aligned, fixing the horizontal tear line that can appear sometimes.
Two methods are available. Try switching methods if your display goes blank.
Warning: not compatible with all displays.
GBS-Control calibrates the ADC offsets on startup.
In case of color shift problems, try disabling this function.
GBS-Control detects interlaced content and automatically toggles deinterlacing.
• Motion Adaptive removes flicker, adds 1 frame of lag and shows some artefacts in moving details
• Bob Method essentially no deinterlacing; no added lag, but flickers
If possible, configure the source for progressive output. Otherwise, using Motion Adaptive is recommended.
Low resolution sources can be either passed on directly or get upscaled.
Upscaling may have some border / scaling issues, but is more compatible with displays.
Also, refresh rates other than 60Hz are not well supported yet.
"Low resolution" is currently set at below or equal to 640x480 (525 active lines).
If enabled, default to 1280x960 for NTSC 60 and 1280x1024 for PAL 50.
Does not apply for 720p/1080p presets.
The default output mode is RGBHV, suitable for use with VGA cables or HDMI converters.
An experimental YPbPr (Component Video) mode can also be selected. Compatibility is still spotty.
If your TV does not support 50Hz sources (displaying unknown format, no matter the preset), try this option.
Warning: the frame rate will not be as smooth.
Reboot required.
Some presets default to not using the entire vertical output resolution, leaving some lines black.
With Full Height enabled, these presets will instead scale to fill more of the screen height.
Currently only affects 1920 x 1080.
Options that aid in development of gbscontrol. Users normally don't need to adjust these.
