Display and Resolution Model

The 0.9.2 renderer separates the logical iDotMatrix screen profile from the physical WLED matrix.

Logical profiles

Screen type	Logical resolution
0x01	16x16
0x03	32x32
0x04	64x64

The logical profile defines protocol coordinates, app-visible capabilities, TEXT sizes and media dimensions.

Physical output

WLED remains responsible for the real LED/panel topology. The Usermod publishes a logical framebuffer to WLED's normal 2D pixel model.

Scaling

For supported 16/32/64 combinations:

• upscaling uses nearest-neighbour replication;
• downscaling uses box averaging.

Examples on a 64x64 physical panel:

• logical 64x64 -> native 1:1;
• logical 32x32 -> 2x upscale;
• logical 16x16 -> 4x upscale.

On dedicated Waveshare and MatrixPortal S3 HUB75 profiles, this output scaling is automatic and the historical low-memory Rescale checkbox is hidden/forced off. That legacy setting is retained only on selected classic low-memory profiles where storing a large logical source directly at a smaller physical canvas materially reduces RAM use.

The physical 32x32 path is not yet a release qualification blocker; logical 32x32 behavior has been exercised through the 64x64 hardware/scaler.

Renderer-specific layouts

Some 0.9.2 content uses native higher-resolution composition instead of merely scaling 16x16 artwork. Examples include:

• combined time/date Clock layouts on 64x64;
• TEXT 16/32/64 rendering;
• static multi-row TEXT pages;
• resolution-specific punctuation alignment in Clock and timers.
