To disable Windows Aero under Windows Vista/7, select the Basic or Classic theme under Control Center > Personalization, or disable desktop composition under. That said, exclusive fullscreen should automatically disable compositing on all Windows OSes, making it the preferred way to emulate in most cases. Aero can be disabled in both Vista and 7, thus disabling compositing and lowering input lag when playing in windowed mode, but this can no longer be done from Windows 8 onward due to WDDM 1.2+. The same thing applies to other OSes if compositing is enabled with VSync. If you're using Windows Vista/7 and are playing in windowed mode, having Aero enabled will add a noticeable amount of input lag because it forces vertical synchronization at the OS-level. These websites makes it a point to test the displays it reviews for display and input lag, so if you're in the market for a monitor or TV and display lag including input lag is a concern, check there first.

Having said that most modern 'gaming' LCD and OLED monitors have 'low enough' display and input lag, and many newer TVs also have negligible input lag so long as Game Mode is turned on. They are also capable of displaying true black levels, which means that they do not require a backlight to produce an image and this allows OLEDs to turn individual pixels on and off much faster than LCDs, which require a backlight to produce an image. OLEDs also have considerable amount of input lag compared to CRTs but there is almost no display lag due to their fast response time and the nature of the technology. Once the frame has been processed, the final step is the pixel response time for the pixel to display the correct color for the new frame.Īnalog CRT TVs and VGA CRT monitors have nearly zero display lag (although its limited by phosphor decay time) and input lag, due to the nature of the technology, the exception being later model HD CRTs that do digital image processing such as High-Definition, 100Hz/doubling the scanrate or 480p inputs (which use scaling). Digital image processing (such as upscaling, motion smoothing and edge smoothing etc.) takes time and therefore adds some degree of input lag as well. This is the lag caused by the modern displays/televisions/monitors (due to the nature of the digital technology). 1.5 BIOS, Bad driver, OS misconfiguration and placebo effect.
