→Ways to reduce input lag
:;Option 1
*[[Display FAQ#CRT TVs|CRT TV]] OR [[Display_FAQ#CRT_monitors|VGA CRT]] (not [[Display FAQ#CRT TVs|HD CRTs]]) with analog input/output. If your GPU only support digital output then use [https://old.reddit.com/user/ahayriSG/comments/16q18h6/highend_dacs_for_crts/ high-end DAC/Digital-to-Analog converters] for higher resolutions and refresh rates (Keep in mind that HDMI ones generally [https://youtu.be/WIDeNItt69s?t=1885 pretty bad]). But what about digital-to-analog conversion input lag? See Aperture Grille's video about [https://youtu.be/puu-iyTsZtg?t=840 testing GPU-Passthrough and cheap DAC input lag results]. Also see [https://hardforum.com/threads/24-widescreen-crt-fw900-from-ebay-arrived-comments.952788/page-435#post-1044652495 this thread] for more information about high-end DACs.
::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[Displays#240p.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU 2F480i|Custom Resolution Utility (CRU)]] or using Linux in KMS mode<ref>https://wiki.archlinux.org/index.php/kernel_mode_setting</ref><ref>https://docs.libretro.com/guides/kms-mode/</ref>. See [https://emulation.gametechwiki.com/index.php?search=%22%23Enhancements|Enhancements%22&title=Special%3ASearch&limit=500&profile=default&fulltext=1 #Enhancements sections] in each page for "built-in custom resolution/CRTSwitchRes" support for emulators.

*[[#External_Links|Fast-TN or IPS panel LCD or fast-OLED display]], also make sure that you mitigate input lag on [[Displays#LCD_monitors|LCDs]] and [[Displays#OLED_TVs_and_Monitors|OLEDs]] by turning on "game mode" from display OSD if available (this will turn off some post-processing options on display). 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 at least mid range GPU.
