Talk:Refresh rate

From Wikipedia, the free encyclopedia

Could someone make a photo of a refreshing CRT (with a very short exposure)? In the long term a diagram/picture would probably be better, but even a photo would help. Paranoid 16:14, 21 May 2005 (UTC)

[edit] Video Refresh Rate

In looking at different display's I keep coming across the same thing for video refresh rate 1 FH, 2 FH, and 3 FH. Does anyone know what this means?

What is this from, some kind of projector? Beyond 800x600, 60 hz was never the most common refresh rate in use, so this 60 hz limit on this can't be that of a normal monitor. All I can guess about the "FH" is that it seems to correspond to the horizontal refresh rate of the different formats - ie the time it takes to scan a single line. This is about the same for NTSC and PAL, double for progressive scan NTSC, PAL, and 1080i, and triple for 720p. But those aren't exact, so if that is it, then I don't see why this representation is useful. Algr 17:30, 16 March 2006 (UTC)

The image is from a plasma manual. I've seen these specifications for projectors and I believe LCD display's as well.

[edit] Refresh rate and field rate

Are these two articles about the same thing? --JDtalkemail 22:08, 10 June 2006 (UTC)

No, only interlaced monitors have a field rate. Algr 15:12, 30 June 2006 (UTC)


[edit] Spreadsheets

I don't think that this belongs here, except as disambiguation. You could also have a section on how quickly various soft drinks end your thirst, but it is still off topic. Algr 19:01, 21 July 2006 (UTC)

[edit] Eyes

It says that 60hz can cause eye strain but i would like it to go more in-depth, also will 60hz on a lcd screen cause any eyestrain?

This might seem a bit silly, but I don't think you mean to say that Windows 2000 is a descendant of Windows XP. Thelbert 20:25, 20 October 2006 (UTC)

[edit] Refresh rate = Max. FPS?

Are the display's refresh rates limiting the FPS when (as example) gaming? Skies 19:40, 2 January 2007 (UTC)

Yes. If the graphics card generates more frames then the monitor can display, some frames will get skipped. They will exist in the VRAM, but never transmitted to the monitor. The smoothest graphics occur when the game FPS and the monitor's refresh rate match exactly. Algr 04:58, 3 January 2007 (UTC)
It depends. If the monitor is drawing a frame and the graphics card sends a new frame, the monitor will start to draw this new frame in the middle of the process. In the end, you'll have a full-frame that is, in fact, a mix of many frames rendered by the graphics card. That's why 'vsync' makes the animation smoother, because it perfectly synchronizes monitor and graphics card. Remember that 'vsync' is different from having refresh rate number equals to frame rate; if they aren't perfectly synchronized the problem remains. —The preceding unsigned comment was added by 201.19.193.36 (talk) 21:14, 1 March 2007 (UTC).

[edit] Eye Perception

It would be intresting if there was any information regarding how the eye and brain percepts the image according to the refresh rate. Such as the human eye can notice a flicker at 50hz but perhaps not at 100hz depending upon screen size. —The preceding unsigned comment was added by 81.179.64.155 (talk) 18:25, 21 February 2007 (UTC).
