That's one of the main reasons to use a media center. Kodi will do that. Jellyfin for AndroidTV will do that. Others like VLC only do motion interpolation, and some work is ongoing for VRR support (notably, AMD GPUs on Linux, but they work with Low Framerate Compensation so it's conside red hacky and with a higher power draw). Of course, higher refresh rates are better, but it's quite wasteful anyway if you only have a 24 FPS. Moreover, not evvery mode is a multiple of that.

> Low Framerate Compensation so it's considered hacky and with a higher power draw This is not hacky or has higher power draw - the display has a minimum refresh rate, and sudden large changes in refresh rate can lead to visible flickering. The GPU and driver is required to handle this. The alternative is much more intelligent display controllers than is currently available anywhere, so the CRTC lives in the display and just receives framebuffer content whenever. > Of course, higher refresh rates are better, but it's quite wasteful It is negligible. Your GPU will do nothing most frames, and the panel power consumption comes from backlight. > Moreover, not every mode is a multiple of that Slow framerates do not need to be a multiple of high framerates, as the error becomes irrelevant. VRR is the solution for fine-tuning for perfectionism.
