120hz LCD monitors still have more input lag, and can't do higher hz than 120hz when needed.
Round pixels? Go read up on aperture grille, boy.
I've been working on CRT monitors for over 20 years and LCD monitors since they hit the market (working on them, not with them) and I know all about aperture grilles. It's only the flat screen monitors that use that type of grille, and not all CRTs are flat. Some use shadow masks. As I mentioned
, not everyone likes square pixels. Also, depending on the tube manufacturer, you may end up with a support wire shadow in your picture (or even two) with aperture grilles. For that reason, some people can't stand them.
So exactly how much higher than 120Hz does your CRT monitor go? 120Hz is far more than enough, especially on an LCD which does not natively flicker like a CRT does (and in the case of a 120Hz model can do the 120HZ at any resolution). Just how high a refresh rate do you think you need? Input lag? Don't use vsync, and turn triple buffering on. You don't get any lag and the tearing should be gone. In all the games I've played on computers and consoles over the last 30+ years, I have never experienced lag. It's a lot more rare than some people would have us believe.
The eye strain is caused by the flicker. Some people experience some strain on CCFL back lit monitors, but most people do not. Hardly anyone experiences it with an LED back lit monitor. When I was using a CRT I lost count of how many times I would be on a major gaming session with red itchy sore eyes. So bad you couldn't close them without scratching and itching. This after working on CRT monitors and TVs all day and then coming home to game all night long and not sleeping until the next morning or afternoon my eyes would be in pretty bad shape. I'm not the only one, and it completely stopped after switching to LCD.
As for radiation. If you had read as many service manuals as I have, and all the X-Ray cautions and recommendations from the manufacturers regarding limiting close proximity to the high voltage and deflection circuits, you wouldn't be so easily disregarding radiation concerns, especially considering a computer user is far closer to his monitor than a TV user would be to watch his CRT TV.
There's still size, weight, calibration drift and image defects (I've had to deal with all of these). You talk about dithering on an LCD, I can talk about moire on a CRT. I could also talk about purity, pincushion, corner pincushion, parallelogram, trapezoid, gun alignment and countless other settings that must be maintained and kept in adjustment for every separate refresh rate/resolution combination because each of these modes uses a separate geometry ciruit. Don't even try to compare calibration and component drift between CRT and LCD because the CRT will lose every time (LCDs don't count on high voltages and currents to keep their pictures calibrated).
As I mentioned, each has it's advantages and disadvantages. I think the disadvantages of the LCD are minor compared to it's advantages. However, if I really needed high refresh rates for some obscure reason, I would look for a 30 or 32" 120 or 240Hz LCD with a resolution such as the 30" HP LCD that will do 2560 x 1600.
the CRT heyday, both working on them and using them. I know all about them.
Still think I need to "read up on aperture grilles"?
Boy? Haven't been called boy in about 30 years.....thanks.
And yes, I'll stop hijacking your thread now.
You can use software called John's Background Switcher at:
To have different pictures on each display, and to change those pictures at different intervals from a library you provide. It can even be set to load on boot, change your backgrounds and exit from memory until your next boot. Great piece of software.
