Hello, I had noticed a high-pitched whine from my monitor while playing the Beta version of a certain game (since the official release, the Refresh rate was lowered). More recently, I had increased my screen resolution from 1024*768 to 1152*864. Since then, I've had a problem with a high-pitched whine. I had lowered the Refresh Rate from 75Hz to 70Hz, which caused the noise to cease... but not permanently. It occasionally recurs and ends later on (sometimes if I turn off the monitor for a few second/minutes); I've come to ignore it after a while. A few minutes ago, the display itself began flickering slightly, and this accompanied by the same whine. As this worried me, I turned down the resolution to 60 Hz temporarily and decided to ask about this. On a side-note, I cannot bear 60 Hz, considering I spend much time on the computer, likely more than is healthy. =P I've been doing a bit of research on the whine, and was reminded that the last time I checked my monitor's maximum refresh rate, I was using a lower resolution. My monitor manufacturer's website does not mention the max. refresh rate for my resolution. I have come here to ask the following: - What are the possible causes of this; could it cause permanent damage or lower the life of my monitor? Or is a failing monitor the cause? Is my monitor capable of handling the 1152*846 resolution at 70 Hz? - Is there any way to calculate maximum refresh rate for a monitor at a given resolution, assuming you have that very data for two or more other resolutions? Or alternatively, could somebody find out the maximum refresh rate for the Daytek DT-95A monitor at 1152*864 resolution? --Laogeodritt

You didn't even try to go to Daytek's website, did you? http://www.daytek.ca/dt-95a.html WILL POST FOR FOOD.

I did, actually. If you'd look yourself, there's no specification for a 1152*846 resolution, which is what I'm currently using. # 1280 X 1024 NI @ 63 Hz # 1024 X 768 NI @ 93 Hz # 800 X 600 NI @ 113 Hz # 640 X 480 NI @ 150 Hz --Laogeodritt

It looks like 1152*846 should do 70Hz concidering 1024*768 will do 93Hz. I have had a few moniters that do this no matter what refresh rate or resolution it is set at and many moniters at school do it to (The are cheapo's) I think it starts to happen once they get a bit old, I cant stand the noise it gives me headaches. What size is your screen? I would set it back to 1024*768 @ 70Hz to avoid the noise unless you need the extra resolution....

Ah, I see. Well, I don't mind the noise, per se, it's only a bit worrying. I switched to 1152*800-whatever because of lack of space though. My monitor is at least 6 years old I'd say. The issue that currently worries me most is the flickering that occured a while ago, which prompted me to change to 60 Hz Refesh rate... or at least, the flickering I thought to perceive. Although otherwise, the whine only shouldn't be a reason to worry (about the monitor), right? --Laogeodritt

I was just playing around with the settings of my monitor at 70 Hz and found this: - In the menu screen, it reports that the display is at 69 Hz. - By decreasing the actual height of the display through the monitor settings, I can get rid of the flicker. - Width of the display does not affect the flickering. - Apparently, the flicker occurs ONLY when the height of the display is such that there is approximate 1/2 centimeter (1/5 of an inch) at the top and bottom of the display. Modifying the height slightly modifies the intensity of the flickering. - Increasing the height of the display beyond the monitor's visible area also stops the flicker. Any ideas? --Laogeodritt

Correction, approx. 1 cm on top and bottom for the most intense flicker. And it also flickers (or perhaps "shakes" would be more appropriate) when the height and width exactly matches the monitor's display area. Sorry for the triple-post btw. --Laogeodritt
