GUI Display
This panel configures how the emulated Amiga screen is rendered on your host display, including window mode, resolution, refresh rate, and color adjustments.
- Selects which physical host display the native chipset output appears on. Only shown when two or more displays are connected.
- The emulator window will be centered on the selected display when starting or switching modes.
- This setting is independent of the RTG display selector in the RTG Board panel — you can assign native and RTG output to different physical displays.
- When Native/RTG autoswitch is enabled, the window automatically moves between the native and RTG displays as modes change.
- Saved as
gfx_displayin the configuration file.
- Sets the width and height of the emulator window in pixels when running in windowed mode
- Window resize: Allow resizing the emulator window by dragging the window edges
- Borderless: Remove window decorations (title bar and borders) while in windowed mode. Only available when Native mode is set to Windowed
- Controls the display mode for the native Amiga chipset output
- Windowed: Runs in a resizable window
- Fullscreen: Switches to exclusive fullscreen mode
- Full-window: Borderless fullscreen using the current desktop resolution (recommended)
- Controls vertical sync for the native chipset display
- -: VSync disabled
- Lagless: Minimizes input lag while syncing to the display
- Lagless 50/60Hz: Lagless mode with enforced 50 or 60 Hz refresh rate
- Standard: Waits for vertical blank before presenting the frame
- Standard 50/60Hz: Standard VSync with enforced 50 or 60 Hz refresh rate
- Controls the display mode for RTG (Picasso96 graphics card) output. Only available when an RTG board is configured
- Windowed, Fullscreen, Full-window: Same options as Native above
- Controls vertical sync for the RTG display
- -: VSync disabled
- Lagless: Lagless VSync for RTG modes
- Enable proper black levels for displays that support it
- Apply scanline doubling to reduce flickering from interlaced video modes
- Render the display in grayscale, simulating a monochrome monitor
- Apply filtering to low resolution modes for a smoother appearance
- Automatically switch to VGA resolution when VGA modes are detected. Requires HighRes resolution and Double line mode to be active
- Blank the screen briefly when the display mode changes to prevent visual artifacts during mode switches
- Sets the horizontal rendering resolution. Disabled when Resolution autoswitch is active
- LowRes: 320 pixels wide
- HighRes (normal): 640 pixels wide
- SuperHighRes: 1280 pixels wide
- Controls how much of the display border area is shown
- TV Narrow through Ultra CSync: Progressively wider visible areas, from a narrow TV crop up to extreme overscan including composite sync borders
- Automatically switch resolution based on the Amiga display mode in use
- Disabled: Fixed resolution, no automatic switching
- Always On: Always follow the Amiga's current display mode
- 10% / 33% / 66%: Switch only when the percentage of lines using a different resolution exceeds the threshold
- Frame skip rate: 1 = every frame (no skip), 2 = every other frame, and so on. Disabled in cycle-exact CPU mode
- PAL: 50 Hz, used in Europe and most of the world
- NTSC: 60 Hz, used in North America and Japan
- Fine-tune the frame rate adjustment value. The slider and numeric field are only active when the lock checkbox is enabled. When unlocked, automatic adjustment is used
- Select which color attribute to adjust using the slider and numeric input below
- Brightness: Overall luminance adjustment
- Contrast: Difference between light and dark areas
- Gamma: Gamma curve adjustment
- Gamma [R] / [G] / [B]: Per-channel gamma correction for red, green, and blue
- Dark palette fix: Corrects very dark palette entries (0–3 range)
- Automatically center the display horizontally on screen. Only available when Overscan is set to Overscan or lower
- Automatically center the display vertically on screen. Only available when Overscan is set to Overscan or lower
- Automatically select an integer scaling factor based on resolution, line mode, and doublescan settings to maintain the correct pixel aspect ratio
Controls how Amiga scanlines are rendered vertically. Disabled when Resolution autoswitch is active.
- Display one line per scanline (200 lines for NTSC, 256 for PAL)
- Display each line twice for better visibility (400 or 512 lines)
- Simulate CRT scanlines by inserting black lines between display lines
- Interlaced field rendering: alternates between even and odd lines each frame
- Enhanced interlaced field rendering with improved blending between fields
Controls rendering for interlaced screen modes. Options depend on the current Line Mode selection.
- Single line mode for interlaced screens. Only available when Line Mode is set to Single
- Double frames mode for interlaced screens. Only available when Line Mode is set to Double
- Interlaced field rendering for double line mode
- Enhanced interlaced field rendering with improved blending for double line mode
