Medical Forum / Diseases and Disorders / Epilepsy / February 2004Another question about photo-sensitivity, this time LCDs
Sorry for asking another question in spite of the fact that I don't suffer from epilepsy. I appreciate the help given last time and I figure individuals posting here have experience with these issues. For my part I have pretty bad anxiety, so that's why I worry about things like photo-sensitivity. Anyway, to my question. I want to play a PSOne game and I'm thinking of buying a Sony LCD Monitor to do it. I assume, like all LCD screens, that it has a 60hz refresh rate. Now aren't LCD screens typically supposed to be easier on people that might have photo-sensitivity? Just checking. Not because I'm having a problem with it, but because I have anxiety and I'd like to know before I crack it open. Thanks and once again I apologize for posting this question here. I hope you understand. Preston > Sorry for asking another question in spite of the fact that I don't suffer > from epilepsy.

I haven't had any problems with the LCD monitor itself. If I view something that's flashing, blinking, or rapidly moving, I just have to be careful even with the LCD monitor. But if I'm just doing normal work, no problem so far. Barb > Preston > I haven't had any problems with the LCD monitor itself.

I guess my question is, would an LCD screen be BETTER for me than a standard television in terms of relieving my anxiety about my photo-sensitivity getting the better of me? (which, I must emphasize again has never actually happened, it's just something I REALLY worry about). Preston > > I haven't had any problems with the LCD monitor itself.

Our tv is far away from the seating, so I wonder if that has anything to do with the tv not bothering me. Barb > Preston Hi there, Here are a few excerpts I have put together from a search I did on Google about LCD monitors compared with Cathode Ray Tube monitors. Since LCD monitors do not employ phosphors, refresh rate is not a concern. Basically, the transistors in the LCD remain open or closed as needed until the image changes. While refresh rates do not apply to LCD monitors, most LCDs are set up to accept any settings from 60Hz and above. Q: Flicker: Do LCD monitors flicker like CRT monitors? A: LCD monitors do not suffer from flicker like their CRT cousins do, and typically run at slower refresh rates than CRT monitors. Q: How can LCD displays improve productivity? A: The completely flicker-free screen is easier on the eyes and thus can be used for longer periods of time. Q: What does "refresh rate" mean to me in an LCD monitor? A: For LCD monitors, the refresh rate is much less relevant. LCD monitors display a stable, flicker-free image at 60Hz. There are no visible differences between 85Hz and 60Hz. Q: What does Refresh Rate mean for LCDs? A: Unlike CRT display technology in which the speed the electron beam is swept from the top to the bottom of the screen determines flicker, an active matrix display uses an active element (TFT) to control each individual pixel and thus refresh rate is not really applicable to LCD technology. Hope this is some help to you Preston. Regards Darryl. -- To reply, change daryl to darryl in address.

Now I have a legitimate excuse not to ever use a CRT monitor again. Thanks for the info.
