hi John, er, just a slight correction here.
a typical basic specfication for a crt is the vertical refresh rate. i believe that is what u're referring to when you mentioned 85. it should probably read as 85hz, ie 85 cycles per second. a typical recommended comfortable value for most pp is 75, altho that requirement goes up as the screen gets larger. fyi, this refresh rate value has nothing to do w sharpness. most consumer LCDs are generally sharper than consumer CRTs, hence being easier on the eyes. some frens in certain creative fields, namely design and architecture, claim that the "pro" CRTs (typically 19" and above) are equally sharp, if not sharper. these obviously come at non-consumer prices as well. also, vertical refresh rate is not really relevant for LCDs. you can refer to http://www.lcdmonitors.philips.com/lcdmonitors/articles/basics_of_lcd.asp Why is a vertical frequency of 60 Hz optimal for an LCD monitor? which will explain far better than i can. for LCD's the more relevant spec is prolly the response time, which is a figure typically between 15-40 ms. the smaller the number, the better for watching video/playing games, as it will result is less visual streaking/smearing/watever you call it. you should also take note of the brightness and contrast ratio, which is impt esp if you work in a very well-lit environment, eg a sun lit room. otherwise, most lcds are "bright enough". enuff said. hope these help. ----- Original Message ----- From: "John Richard Smith" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, August 26, 2003 20:46 Subject: Re: [newbie] Dell TFT 17"Flat Screen > I see, so in regards to TFT's it's not a case then of a beam of > electrons scanning the screen top left to botton right so many times a > second ( CRT of 85Mhz = 85 refershed scans per second) but a question of > how many times a pixel is electronically swithced on and off > electronically, that is by a circuit behind that pixel ? > > So a TFT with a refresh rate of 16ms is being switched on and off, > 16/1000of a second each time.
