Sorry ron, I haven't found any other solutions to the monitor Self Check displaying after the computer power is off, so I just manually turn off my monitor.
A lot of times I just leave my computer turned on, and I have my screen saver set to display a completely black screen, so that is another possibility, although obviously it is desirable to turn the computer and monitor off occasionally... Maybe you could plug the monitor into a power bar, and turn the power bar switch off after the computer has been powered down, it you want to avoid having to pull out the monitor power cable... although that is a pain too.
that is so SAD!
had this problem on a Dell 2405 LCD monitor. it was turning off fine whenever the computer went to sleep. then , albeit after plugging/unplugging the video connector into other machines, it would just display the 'self test' message whenever the computer was sleeping. turns out I had bent one of the pins on the video cable. after i fixed the pin, all was well again. check your pins/connectors, worked for me!
Yes I have the same problem, the Dell monitor not only always have the "self check" on all the time, but also the power switch doesn't work.
The design is so foolish and the quality is also very bed with the power switch not working.
I will not buy any Dell product any more!!!!
I'd been living with this problem for nearly a year, when my wife got fed up and asked me to fix it. After poking around a bit, I tried simply changing the cable from the laptop to the monitor (suggested elsewhere: I never would have thought of this myself). That definitely fixed the problem. Using the old cable causes the Self Test block to appear; swapping the new cable in makes it sleep peacefully.
Please note that the old cable is a pretty functional VGA cable. There are no bent pins on either end and the video is fine. It appears that all cables are not created equal..
My screen started doing the same DVI test. I have been having this screen for over 5 years and never experienced this. Checked all the settings on the screen, computer setting whatever related to the monitor or power settings even I knew I did not change anything lately and I did not find anything suspicious, Then Googled 'DVI self test' and was amazed to see the same questions posted all over the net. I saw a few posts about the dvi cables either damaged or loose.
I recalled a few days ago I disconnected the dvi cable from the computer a few days ago. When I plugged it back I did not use the long screws to secure it, since I knew I had to disconnect it again in a few days. I'm not sure this was a problem or because I moved the computer nest day and the cable got slightly loose. But the screen was working normal, I did not have any issues with the picture or anything else. So I reconnected the cable and secured it with the screws. Problem solved!!! The confusing thing was the screen was working fine.
I hope this will help you guys who will run into the same issue.
My son's computer monitor started doing this. He is away at college so no one has messed with any cables or settings. The computer itself is turned off. The monitor comes on by itself with the Dell Self Test box displayed. I've manually turned the monitor off twice and both times it later TURNED ITSELF BACK ON. Needless to say, this is kind of creepy! I've now turned it off AND unplugged it. If it turns back on this time I'm throwing it out!
