OSSC potential incompatibilities
Jump to navigation

This page lists consoles which can be incompatible with some displays when used with OSSC. Home computers and more exotic arcade boards are not included since their outputs often deviate from PAL/NTSC spec to a degree that they are not compatible with TVs but with PC monitors only. Capture card compatibility is neither considered since with some exceptions they are the most picky devices when it comes to non-standard refresh rates and line counts.
| Console | Why? | Test method |
|---|---|---|
| NESRGB / SNES in 60Hz mode | Hsync period is not constant, causing some jitter to output clock. Some displays are sensitive to this and cannot properly lock to the signal (low receiver PLL bandwidth). | No known external test method. |
| PSX in 50Hz non-interlaced (288p) mode | 314-line output becomes 628 when linedoubled, not within +-1 lines of 625p@50Hz spec as required by some displays. | ModeLine "PSX_288p_x2" 27.00 720 732 796 864 576 581 587 628 -hsync -vsync |
| Jaguar in 50Hz non-interlaced (288p) mode | ||
| Neo Geo | 264-line output becomes 528 when linedoubled, not within +-1 lines of 525p@60Hz spec as required by some displays. MVS additionally uses 59.18Hz refresh rate that is too far from 60Hz for some TVs. | ModeLine "MVS_240p_x2" 26.81 720 736 798 858 480 489 495 528 -hsync -vsync |
