Frame Skipping Check: Test for dropped frames & missing display refreshes.
(1) Take photo of this screen with camera. Screenshots won't work. Use 1/5th second exposure or longer to capture multiple squares. If camera exposure can't be raised, decrease camera ISO and/or reduce monitor brightness, to make camera do longer exposures. If you see only 1 or 2 white squares in your photo, try again.
(2) Photo should not contain any popup messages. Take photo when you see "VALID" at bottom of page. The message "VALID" does not confirm frame skipping.
(3) Check photo for frame skipping. Compare to example good photo and example frameskipped photo. The photo should have a sequence of multiple solid squares, with no gaps in between. If there are gaps, then there is frame skipping. For testing refresh rate overclocking or HDTV refresh rate overclocking, close all other apps and browser tabs, run this test with nothing else running, and check browser requirements. For an alternative tool, see Refresh Rate Multitool from shurcooL on HardForum.
(4) Post your display overclocking results in the new Blur Busters Forum!
