PixelFX Morph 4K Firmware v4 Introduces Major FPGA Overhaul and Advanced CRT Simulation

PixelFX launches beta firmware v4 for Morph 4K video processor, redesigning FPGA processing with analog signal models, PDM-20 virtual CRT, and auto-rotation.

Retro enthusiasts searching for the authentic appearance of a cathode-ray television without sacrificing modern display convenience have received a substantial software upgrade. PixelFX has released a beta version of firmware v4 for its Morph 4K video processor, introducing a major redesign of the device's FPGA processing architecture. Rather than simply adding another selection of scanline filters, the developers have implemented more sophisticated simulations of the physical processes behind analogue video. These include composite and RF signal behaviour, colour decoding, electron-beam characteristics, phosphor illumination and traditional CRT geometry. One particularly ambitious feature is the PDM-20 virtual television, which recreates the appearance of a twenty-inch CRT within a simulated cabinet. Users can adjust convergence, curvature and phosphor effects to produce different visual results. The update also introduces automatic screen rotation for vertically oriented arcade games, improved deinterlacing and additional scaling algorithms. A new rational decimator is intended to address uneven pixel scaling in selected retro collections, while Film mode can reconstruct progressive frames from suitable interlaced sources. The configuration interface has also been reorganised to make the growing feature set easier to navigate. Firmware v4 is currently distributed through the preview update channel, making it experimental software rather than a final stable release. Support for related Morph 2K and RetroGEM products is planned for later. The update demonstrates how much engineering continues to be invested in displaying vintage games accurately on modern screens. Original consoles were built for televisions that handled video very differently from contemporary OLED and LCD panels. PixelFX is attempting to bridge that gap through increasingly sophisticated digital processing. Apparently the ultimate achievement of modern display technology is making an expensive television look convincingly like one from 1992.
