→Ways to reduce input lag
**Use Custom resolution/CRTSwitchRes solutions for displaying it on a CRT display in the correct resolutions. You could use built-in Custom resolution/CRTSwitchRes solutions like RetroArch's [https://docs.libretro.com/guides/crtswitchres/ CRTSwitchRes] or [[GroovyMAME]] using with [http://geedorah.com/eiusdemmodi/forum/viewtopic.php?pid=1009#p1009 CRT emudriver] which is much more practical compared to using EDID editor tools such as [https://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU Custom Resolution Utility (CRU)] or using Linux in KMS mode<ref>https://wiki.archlinux.org/index.php/kernel_mode_setting</ref>. See [https://emulation.gametechwiki.com/index.php?title=Special:Search&limit=500&offset=0&ns0=1&search=%23Enhancements #Enhancements sections] in each page for emulators compatibility with "built-in Custom resolution/CRTSwitchRes".
*If you don't have a CRT, you can mitigate input lag on [[Displays#LCD_monitors|LCDs]]/and [[Displays#OLED_TVs_and_Monitors|OLEDs]] turn by turning on "game mode" from display OSD if available (this will turn off some post-processing options on display) and if your LCD display is old set your [https://www.youtube.com/watch?v=Qdp7VfLXnB4&t=279s native resolution to native panel resolution] for preventing possible poor quality hardware display scaler otherwise you can use [https://forums.blurbusters.com/viewtopic.php?t=6155#p46190 GPU scaling] if you have high~mid range GPU.
**If you have a "gaming" monitor you can also turn on "overdrive" option if available for overclocking pixels (applies overvoltage to pixels) making them react faster (better pixel response time) which results in less ghosting. That said, increasing pixel overdrive may cause inverse ghosting as the increased voltage can cause the pixels to [https://www.rtings.com/monitor/tests/motion/motion-blur-and-response-time#test_4246 overshoot] the colors. See [[#External_Links|these websites and reviews]] to learn information about your display devices capabilities and performance.
**Also you could also use latest [[MAME]] with "[https://shmups.system11.org/viewtopic.php?t=65615 -lowlatency]" flag for your variable refresh rate supported monitor.
