I have this monitor and the quality is good but just in the last day or two, the monitor will suddenly flicker black and red for a few minutes

I had a something like that happen but only because of a bad connection with my cables and I was trying to do a dual monitor with a lesser resolution. FixING the cables and getting a better second monitor fixed it for me. Hope you didn't just get a bad monitor

I have flickering problem in a different brand, from day one. Square Perfect has worked without flickering though. I have them on about 6 hours everyday for the last 25 months. I wonder if yours is a one off, or if there is a bad batch out.

Have you checked the outlet it's plugged into to see if it's hot? If you experienced a power surge when the outage occurred it may have fried the power supply. (We had this happen to several devices plugged into a surge suppressor when we had a lightning strike.) If you've only had this monitor for a short time (less than the 1 yr warranty coverage) you might contact Dell for guidance. Other than that, I can only suggest you have a tech look at it to determine cause and possible repair.

I've had mine for almost six months and it happened couple of times. I've noticed that it never happens when I watch a DVD or Blu-Ray disk, or when I am streaming something either from Internet or my media server. It only happened when I was watching cable using my Comcast digital cable box. When it happens it goes black and comes quickly right back. Before it comes back it shows for a split second a sign that it is establishing HDMI connection. I was wondering if it has something to do with the cable box, but it is so rare that it is difficult to identify a pattern.

My screen would come on briefly and go black. The 2 main capacitors for the power supply were bad. It took 15 min to unsolder old capacitors and solder new ones and works perfectly. I have the other just in case for a fraction of what I would have been charged to diagnose the problem. I would say yes if that's your problem.

No, the general symptom that would cause one to replace this part would be the monitor works but the image is very dark. I think flicker rate might be associated with the video cards scan rate such as 60 hertz. The higher the hertz the better the flicker rate or refresh rate. Play with different screen resolutions and refresh rates to get a smooth screen image.

Yes. I had it with my first one. Sent it back and they sent me a new one. New one started doing it again after 3 weeks. It's something to do with the connection. not sure about the quality of shielding used in the cables. If I move the cables around in the back of the monitor it will sometimes go away for a day or so, but always comes back. Annoying as hell. The only issue I've had with it so far.

Check for loose wiring/loose fittings first. Second would be to try changing the resolution on screen. Last would be your monitor is going out. Let's hope that's not it.

I have never had that problem. It is probably just your particular monitor. You need to contact Amazon and they will get you another or do something to help you out.

My screen does not appear red and I have been running it for a year. I suspect either a video card issue, a wiring issue or a monitor issue. Good luck.

Double check your settings on the monitor. Mine didn't come with DisplayPort 1.2 enabled by default. You may be getting a 30 Hz refresh rate. Similarly, if you're using HDMI and not DisplayPort, you'll be stuck on 30 Hz not 60 Hz. I just turned mine way down and didn't notice any flicker.

I'm using it as a monitor right now - LOVE it! The only thing is, and I'm not sure if it's my computer or the monitor, is is goes BLACK for a couple of seconds every once in awhile. No big deal as it returns right away, even before you could grab the remote. I haven't noticed it do that wile using any of the TV functions yet, but I haven't had it very long.

I have the flicker with mine with YouTube and other video sources as well. Not sure what the problem is yet but I'm looking into it.

I have upgraded monitors twice now and haven't had a problem. Try testing the monitor on another computer and try using a different monitor cable as well

I've had the monitor for about a year. I haven't had any problems with it. You might check your computer's energy saver settings to see when your monitor is set to go to sleep.

Are you using the cable that came with the monitor? I had some issues getting mine setup, but it was related to the cable I was using. You may want to try using a different cable rated for the high resolution that the monitor offers.

If one of your monitor stop working, it might be the power connection (DC 12V). Check the connector is it proper connect or disconnect.
