Signals/Resolutions: The for RetroScaler2x can accept 240p/480i/288p/576i NTSC/PAL sources to converter to 480p/576p HDMI output (480p for NTSC, 576p for PAL). For example 240p signals are supported properly, allowing for a completely progressive linedouble to 480p. 480i signals are deinterlaced and doubled also to 480p. Keep in mind that the output resolution of this device only up to 480p/576p. Zero Lag: The for RetroScaler2x is a zero lag device, proven using multiple measurements and different devices. Region Compatibility: Both NTSC and PAL signals are supported, but they are not converted to each other. That means you can plug in whatever signal your target device is compatible with, but NTSC might not work on PAL HDMI devices and vice versa. Filter Modes: The "FIL" mode is completely preference-based, but the average retro-gamer prefers the FIL mode off for 2D games (for SNES, for Genesis, etc) and on for 3D games (for N64, for Saturn, etc). Also, the FIL mode might help reduce flicker with some 480i-only games. Compatibility: Another great feature of the for RetroScaler2x is that it outputs a true 480p60 signal, making it compatible with every device I tested it with! Compatibility is a big issue for retro-gamers, as modern displays aren't used to the resolution or refresh rate of these older consoles. This device is an excellent help for streamers who want the highest chance of compatibility. Performance - Audio: Audio performance on the for RetroScaler2X is good. In general uses there are no issues with the audio digitization but on brassiere sounds like explosions the output may sound a little rougher than it did through the OSSC. This isn't something you're likely to even notice on a TVs speakers, though you might if you have an external amp or home theatre system. In that case of course, it's usually perfectly easy to route audio aroun
