Umehluko ku-smear. Ngokuvamile, akukho smear esikhathini sokuphendula esingu-1ms, futhi i-smear kulula ukuvela esikhathini sokuphendula esingu-5ms, ngoba isikhathi sokuphendula yisikhathi sokuthi isignali yokubonisa isithombe ifakwe ku-monitor bese iphendula. Uma isikhathi siside, isikrini siyabuyekezwa. Uma kuhamba kancane, kulapho amathuba okuthi ama-smear avele khona.

Umehluko ngesilinganiso sohlaka. Izinga lohlaka elihambisanayo lesikhathi sokuphendula esingu-5ms lingamafreyimu angu-200 ngomzuzwana, kanti izinga lohlaka elihambisanayo lesikhathi sokuphendula esingu-1ms lingamafreyimu angu-1000 ngomzuzwana, okuphindwe kahlanu kunelokuqala, ngakho inani lamafreyimu ezithombe angaboniswa ngomzuzwana lizoba ngaphezulu, lizobukeka libushelelezi, kodwa futhi lincike esilinganisweni sokuvuselela sesibonisi. Ngokwethiyori, isikhathi sokuphendula esingu-1ms sibonakala singcono.

Kodwa-ke, uma abasebenzisi bokugcina bengabadlali be-FPS abangochwepheshe, umehluko phakathi kwe-1ms ne-5ms uvame ukuba mncane kakhulu, futhi ngokuyisisekelo akukho mehluko obonakalayo emehlweni enyama. Kubantu abaningi, singathenga i-monitor enesikhathi sokuphendula esingaphansi kwama-8ms. Vele, ukuthenga i-monitor ye-1ms kungcono kakhulu uma isabelomali sanele.
