'No Signal' Digital

The monitor works fine at start up and I'm using it now, but everytime a fullscreen game is opened the monitor will switch off and display 'No Signal Digital' It's not the game, BioShock, since this has happened when playing other games that had worked before. I have had the monitor for a month and a half, but this has never happened.

Solution #1 worked on my Viewsonic LED monitor today (18/01/10) so the problem is not limited to that particular monitor - but it does sound like it is a Viewsonic issue. Thanks

It sounds to me as it your monitor has a fault in the scan control circuitry, when it goes to change resolution.. ie: change frequency, the oscillator fails and the unit shuts down accordingly.. It may possibly be the Monitor Drivers, have you installed those? But even if ya haven't I don't really think this will make any difference, but one must try all things. Also make sure you have the most-up-to-date Drivers for your Video card as well B4 proceeding. If it indeed ends up being the Monitor being faulty, IE:Installing/Reinstalling Drivers etc doesn't change the behavior and because you have only had the unit for that short amount of time, & it has this "Fault". Then I feel ya should take it back for replacement/repair... under manufacturers warranty.. as this is not acceptable.

I spent 4-5 hours investigating this problem and the solution ended up so simple it was scary.
1. Keep the DVI cable connected to both PC and monitor
2. Turn of computer
3. Disconnect monitor power lead from monitor for 10 seconds
4. Plug it back in and off you go

Many upset Viewsonic purchasers have returned their monitors having not been able to resolve this issue!!

Monitor shuts off randomly!

1. This is main-board related. You either have a Micro controller or power supply issue that needs to be address by a tech. Shut down is direct relation to a circuit component in the start up that has failed.

When computer is started no signal appear on the monitor.

If your monitor is working fine, my guess is you might forgot to turn on the monitor power switch which is located at the lower right bottom corner. try it

No analog signal

Sounds like the graphics card is gone belly up. Try the monitor with another pc or just replace the graphics card.
Hope this helps

Acer monitor lcd problem

Try the monitor with another known working computer, If ng there also, then have unit repaired under Acer warranty.

Analog output works fine, but no signal for digital output

Monitor out of range

Most commonly, this problem is caused by an incorrect refresh rate setting. LCD monitors typically DO NOT support refresh rates higher than 60hz - and this is no exception. Try running the game in "safe mode" if it has one. Adjusting the in-game video settings should solve the problem, just look for a screen refresh rate or any video-related setting with a number followed by "hz". Set it to 60, everything should be fine.

It could also be that at some point the game changes resolution (this frequently occurs if there is an in-game movie or cut-scene). In this case the resolution settings for the in-game movie might be at fault, check them if you can.

No digital signal but analog works fine

Seems like this was already answered? But once you've checked against the owner's manual and ruled out the PC, I would suspect the signal / video board inside the monitor. May have gotten a surge or static, etc.
