Hello everyone. I would love to get some thoughts on the following issue:
I have an approximately 2-year-old I-Inc iF281D monitor. Its native resolution is 1920x1200. Several months ago, it developed an issue where the display would go black for about 2 seconds, then resume again as if normal. A faint "tap" or "tap-tap" sound could be heard in the background as it did that. It started doing that about once every two weeks. However, the frequency gradually increased, and now it has gotten to the point when the flickering occurs nearly constantly (off for two seconds, on for a fraction of a second, off for two seconds, on for 10 seconds). The length of time between the flickers seems random, but the flickering tends to occur in stretches (flickers for 20 minutes, then stops for 10 minutes, then flickers for another 40 minutes, etc.) You can still hear the tapping sounds with each flicker, but they seem to have gotten louder, at least on certain individual flickers. In any event, the flickering is now so bad that the monitor is not usable. During the flicker, the power light stays on.
A few observations that I have made:
1) I have replaced the video card with a different brand and chipset, but the problem has not gone away, so the problem is presumably with the monitor. I have also replaced the HDMI cable connecting the video card to the monitor.
2) It may be just me, but it appears that flickering is more likely to occur, and is more severe, when I use Google Chrome. I am not sure why this could possibly be the case, but it is an observation. However, the flickering is not exclusive to the time I use Chrome, and occurs with other applications as well.
3) The flickering nearly disappeared when I switched the monitor from its native resolution (1920x1200) to a lower resolution (1680x1050). Maybe one or two flickers occur shortly after I switch from high resolution to low, but then the flickering disappears completely. When I switch again to 1920x1200, the flickering returns, so I always have to switch back to 1680x1050. (The picture looks ugly, but that is a different story.) This is how I am using the monitor now.
I would like to be able to use the monitor at its native resolution (1920x1200) without the flicker, but I am at a loss. Thoughts?
System: Dell Optiplex 790 (my office system)
4GB RAM
OS: Win 7 SP1 Professional x86
Video card: Sparkle GeForce GT520 (1GB DDR3) (current card), ASUS EAH5420 (512 MB) (previous card), both PCIe, in both cases the monitor is on the HDMI connection, in both cases the most current drivers. There is also a second monitor, a ViewSonic VA926g, on the VGA connection. (I tried disconnecting it, which has exactly zero effect.) The second monitor is unaffected by the flickering.
