**Horizontal resolution is only limited by video bandwidth, so you can set it really high and scale output to fit, and the CRT will display it 4:3. This is useful for 240p modes where you can avoid having to have different custom resolutions for each game and not have any visible scaling issues due to individual horizontal pixels being smaller than your monitor's dot pitch. | **Horizontal resolution is only limited by video bandwidth, so you can set it really high and scale output to fit, and the CRT will display it 4:3.

− | + | ==Black frame insertion== | |
− | + | For 120hz monitors. | |
− | |||
− | + | Simulates CRT flicker, which is necessary for the human eye to perceive fluid motion. Without it, the sample-and-hold method used by LCDs manifests as motion blur to our eyes. For LCDs, running at 120Hz with black frame insertion every other frame gives you 60Hz CRT motion quality on 60fps content, and is especially effective on strobe-backlight gaming monitors (e.g. NVIDIA LightBoost, EIZO Turbo240, BENQ XL2720Z Blur Reduction). | |
− | + | For CRT monitors, they can use a 120Hz refresh rate to sync to 30kHz (240p) resolutions. | |
− | + | However, 240p at 120Hz can create motion blur, due to having twice as many frames being drawn on screen and overlapping. The solution is to draw a black frame every other frame. At 120Hz that essentially brings it back down to proper 60Hz. The issues are that brightness is halved and any frame drops are very noticeable. | |
− | |||
− | + | In RetroArch there is an option for black frame insertion in the video options in RGUI. This makes it draw an extra black frame for every frame and it succeeds in making the motion smooth at 120hz. There is an option for the swap interval. | |
