If a LCD monitor's resolution is listed as 1280x1024 @ 135 MHz, does that mean that resolution is only available at that refresh rate? What if a lower refresh is used? Would the LCD monitor change the resolution to something lower, or would it stay at 1280x1024, but with just a lower refresh? I'm assuming that anything lower than the 135 MHz means a lower resolution. But, I wouldn't be surprised if I was wrong. Incidentally, the thin clients will most likely be based on the Via EPIA 5000 motherboards. Their on board video can do 1024x768x16 and 1280x1024x16 @ the max 85 Hz, 1600x1200 @ 60 Hz.
I am very interested to learn what the _real_ answer is to your question, but in the mean time, I can give you my interpretation of the 1280x1024@135MHz spec. (Keep in mind, I am an expert at making up rational sounding explanations for questions about which I know nothing at all...) I interpret the 135 MHz as a maximum pixel clock spec. 1280 columns * 1024 rows = 1,310,720 total pixels per frame. At 135 MHz, this implies (to me) that you could update (i.e. refresh) the display at a maximum rate of 103 times per second. But this number doesn't take into account any time dedicated for vertical and horizontal retrace. In my mind, these are anachronisms that hearken back to the days of CRT's, and I can't imagine any reason why an LCD display would need any extra time at the end of each line, and at the end of each frame, but perhaps there are reasons. I would love to hear from somebody who knows what (s)he is talking about here... Just out of curiosity... What LCD Monitor are you looking at? Does it have a digital interface to the graphics adapter or an analog interface? Is the digital interface serial (in which case you need to divide my 103 Hz refresh rate by 8, 16, or 24 -- yech!) or is the digital interface parallel? I expect these are all standardized by some DVI specification, but I have no expertise in that area (if that's not totally obvious by my post thus far). perhaps this helps... probably not :-) --wpd -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
