Is My Monitor Dying?

Okay, I've had my monitor for almost 5 years now, and it's been working absolutely fine. However, the past few days or so, particularly from a cold/new boot, if the pc has been off for awhile, it doesn't come on. My computer boots up fine, but there is no signal. It just has a signal sign flashing on and off on a blank screen and the power button flashing on and off. Sometimes it eventually works like if I pull out the power connector and then put it back in. But not always. Or if the monitor goes into sleep mode, it does the same thing. Really not sure what to think! Like it still flashes up the like the signal output, so there must be some thing working. Like it's working now. Just worried it could be something worse.

When I say it goes into sleep mode, I mean the power settings were set to turn the display off after an hour of non-activity.

Sounds a lot like my old monitor - if I could get it started then it would work without a problem all day. But getting it started could sometimes be very difficult - I'd need to keep plugging/unplugging the power or plugging/unplugging the GPU cable.

Unfortunately I never found a way to fix it - after a while I bought a new monitor and had no problems at all. If possible I'd suggest trying another monitor on your PC, or trying your monitor on another PC - that should hopefully confirm whether the monitor or the PC are the cause of the problem.

Yeah. I'm going to try a few things. Turned on computer after 3 hours just now and worked fine. Maybe installing new driver helped. But probably do it again. Have to see. Most likely is the monitor slowly dying.

New driver didn't do any good. Going to try it in save mode. Did your monitor still display the Bios/Motherboard logo i.e. ASUS? Mine sometimes does. But as soon as Windows starts, it loses it's signal and turns off. Only comes back if I pull out any cable like you did, then put it back in. Weird :(

Don't think it's my monitor. Think it's the port in the DVI port (white one) in the graphics card. Tried changing a couple of connectors around. I put the same connector with HDMI on the end into my tv and there was no signal. Then I put the connector in the other DVI port (yellow one) and it worked fine. Could be a dodgy connector. But seeing as it worked straight away by switching them around, it looks like the GPU is at thought. Which brings me to the question. My GTX 970. It has a yellow DVI port and a white one. Is there any difference to them both?

In relation to the two different DVI ports, I believe one is DVI-D and the other is DVI-I. See http://nvidia.custhelp.com/app/answ...at-is-the-difference-between-dvi-i-and-dvi-d?

Unfortunately I don't really remember whether my monitor sometimes displayed the BIOS/Motherboard logo. I want to say yes, but I can't really be sure. I do remember that it showed no signal a lot.

I also used to swap the DVI cable between two different outputs on my GPU. And for quite a while this seemed to do the trick to get my monitor started. But after a while it began to get harder and harder to start the monitor up.

However the fact that there's no signal on your TV suggests that it could be a GPU problem rather than a monitor problem. Unless there was some setting that needed to be changed on the TV to get it working (I know that my current TV is really complicated to get it to work half the time!).

Cheers for the reply. Yeah I think the white DVI port is only for digital, and the yellow is for either digital or analogue. I've bought another connector anyway, so might see if it works on that. Maybe it's a dodgy connector I have. In all fairness, if it is the GPU port that's faulty, I'm not too fussed as long as I can use the yellow one, or even HDMI if need be. What's actually better though? HDMI to HDMI (I use that for GPU to tv), or DVI to HDMI? Would it be more better to use HDMI to HDMI for my computer rather than the tv, or keep it as it is?

The only difference between DVI and HDMI is that HDMI can also transmit audio whereas DVI cannot. So if you are using only the video part then it doesn't matter which connection you use.
