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

Every time I'd turn the screen on it would be perfect, then after about 5 seconds the entire screen would become a dead pixel. The PCB going bad is apparently a common issue with these monitors. I told the seller about the issue and they paid to have it shipped back to them, no hassle. Got another one and it's perfect, no dead pixels.

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.

I have a bad experience with you. I use the screen lcd for only one day. After a day, its become black, i can't see anything.

I didn't have that problem but there was a glitch in mine which made my screen flicker. I believe that it's a manufacturing issue. If you can't get it to work, is send it back and ask for another one

Never (using this monitor since 6-13). Do you have a message on the screen when this happens - "no xx input," etc.? Check cables.

Sorry you are experiencing issues. We had none. We hooked it up and both monitors are displaying just fine.

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 don't think this is one of their "eye care" monitors. Personally, I haven't had any flickering problems. I run all my games in 1080p and don't have any problems. I hope this helps and wish you well on your search for a good monitor.

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.

Make sure your mini display port is enabled. If you are using HDMI it causes that flicker because it's at a different frequency. If you use the mini display port it will be clear and very smooth motion that will help that eyestrain greatly.

Yeah it happens to me too!! Can't narrow down what causes it. Monitor? Video card? My blackout screens happen randomly and lasts anywhere from 1sec to about 3-5 seconds

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

It could be a number of things. First thing I would do is check all of your connections. Unplug and reconnect just to be sure. Check your power supply. If you have another monitor hook it up and see if it might be your video card. If you do those things and everything is connected properly, and the other monitor works fine then I would say you need a new one.

I would check the back of the monitor too, making sure that nothing got changed there. I've had mine for over 2 1/2 years and it still works perfectly! I love it!!! If you check the back and everything is as it should be, definately contact the manufacturer and get it replaced!

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.

Full disclosure, I'm not a repair person or expert at all. With our set, it started with a loud humming and kind of digital chirping noise. Then the picture started flickering a few days later, followed by the screen getting pixilated and greenish shortly after. Replacing the color wheel solved the problem and it's worked fine for more than two years now.
