Here's a video that shows the RetroTink-4k in action - including how profiles work and how awesome a job it does!
Please note that this shows the standard 4k model, not the 4k CE. Read below for differences between the 4k and the 4k CE.
The RetroTink-4k CE is basically a cheaper version of the RetroTink-4k. While some of the functions had to be cut, it will still be good enough for most gamers.
These are the differences between the 4k CE and the 4k model:
- No Rotation Support
- Input Width Limitations: Maximum input source horizontal width is limited to 2048 pixels. (This does not affect MiSTer or other super-resolution sources decimated to a lower effective resolution).
- De-Interlacing: Linear motion-adaptive de-interlacing only without advanced sensitivity controls; no bob field offset adjustments, no edge-adaptive interpolation. First order field differences only, enhanced motion detection using second order field differences not possible.
- Inverse Telecine: No support for inverse 3:2 to de-interlace telecine content or to reconstruct 24 fps sources from 60i and 60p. No support for inverse 2:2 for PAL content and reconstructing 30 fps games output in 480i.
- No IIR Blur Support: Horizontal softening can still be accomplished by using cubic, Lanczos or bilinear soft interpolation filters.
- BFI: Basic BFI insertion of black whole frames only. No alpha bending or colored insertion.
- S-Video: No enhanced S-video support. Regular SDP decoder only.
- XBR Smoothing: Not included.
- NTSC Composite Video: No 3D comb filtering. Notch and 2D modes only.
- Auto-Phase Adjustment: Continuous background auto-phase is not available (auto console sample rate detection is still included, but users will need to calibrate and save the phase to their profile during first use). On demand auto phase (by pressing the button) is still supported.
- OSD Color Depth: Reduced color depth for the banner image from 11 to 6 bits.
These are the features of the 4k CE:
