screen refresh rate

[spiridusu]

am si eu o curiozitate.Am cautat pe net dar nu am gasit nimic concret.Ce face optiunea "Screen refresh rate" de la monitor?Trebuie setata mereu pe valoarea maxima?Am vazut pe net ca multa lume spune de 75-100hz dar eu am doar 50, 59 si 60.O zi buna

refresh rate = de cate ori pe secunda sa redeseneze imaginea pe monitor

CRT: E recomandat sa nu folosesti rate de refresh mai mari decat cele recomandate de producator la rezolutia respectiva. La ecrane mai mari de 17, e recomandat cel putin 85Hz (sub 15 nu deranjeaza nici 65-75Hz), chiar 100 daca poate monitorul.

La LCD, nu exista rata de refresh, exista response time, care inseamna cat de repede poate monitorul sa aduca un pixel de la negru la alb si inapoi la negru, adica viteza de iluminare.

La televizoare e 50Hz (PAL-SECAM) si 60Hz(NTSC). Practic, ar putea fi mai mare, dar standardele au fost create in anii '20, cand tehnologia nu permitea rate de refresh decat egale cu frecventa tensiunii de alimentare.

ok si daca la laptop am 3 optiuni, 50 59 si 60 pe care este indicat sa o folosesc?

maxim 60.

60 hertz e cel mai bun, si cel mai folosit.

eu am la monitor 75hz + rezolutia 1024x768

Depinde de monitor, eu pe CRT folosesc 75 si in unele jocuri trec la 85 ca sa nu ma usture ochii.

Voi n-ati inteles nimic.

Much of the discussion of refresh rate does not apply to the liquid crystal portion of an LCD monitor. This is because while a CRT monitor uses the same mechanism for both illumination and imaging, LCDs employ a separate backlight to illuminate the image being portrayed by the LCD's liquid crystal shutters. The shutters themselves do not have a "refresh rate" as such due to the fact that they always stay at whatever opacity they were last instructed to continuously, and do not become more or less transparent until instructed to produce a different opacity. Most of the TFT LCDs used in portable devices and computer monitors need a continuous refresh. The driving voltage determines the transmittance of the liquid crystal. The closest thing liquid crystal shutters have to a refresh rate is their response time, while nearly all LCD backlights (most notably fluorescent cathodes, which commonly operate at ~200 Hz) have a separate figure known as flicker, which describes how many times a second the backlight pulses on and off. However they also have a refresh rate that governs how often a new image is received from the video card (often at 60 Hz).

@Orange: pe ce diagonala folosesti tu 75Hz :-s

Eu folosesc 1280x1024 @ 100Hz pe CRT 19 si 1920x1200 @ 85Hz pe CRT 24.

Pe 17" folosesc 75hz in desktop si Counter-Strike si in alte jocuri spre exemplu Talisman online folosesc 85hz cu o rezolutie de 1024x768.

eu am 59hz pe rez de 1440x900 si nu ma ustura ochii deloc

Berkley, pe CRT?

Pe CRT daca pui te ustura ochii, sau poate asa te-ai obisnuit, in fine, acum depinde si ce monitor ai, cat suporta monitorul dar si placa video
