Question about NEC LCD1712 17" Flat Panel LCD Monitor
I am having a rather peculiar issue with my NEC LCD1712 which I am currently using as my secondary monitor. It works perfectly fine as I boot up the computer. It displays "welcome to windows!" and all that jazz. However, once I log in, it reverts to just a black screen. I believe it says "no signal input". I am not sure when it started, but I noticed that the display of my primary monitor was shifted over to the right for some reason. I started messing with my graphics card's software "Catalyst Control Center". I used the "restore factory defaults" option and it rendered my NEC monitor black. Thank God my primary monitor was just fine and I was able to fix the image shift later. However, now I cannot for the life of me find a way to get my secondary monitor back up and running. All of my drivers are up to date. I have tried adjusting the resolution and refresh rate of the monitor. I have tried duplicating the displays and making adjustments with my primary monitor. If I only have my primary monitor plugged in on startup, it will behave the same (display up until the log in screen and then blackness). I find this problem to be both peculiar and extremely frustrating. If anyone out there has a solution, it would be greatly appreciated. Here are some specs: Operating System: Windows 7 Home Premium 32-bit System Model: Vostro 230 Processor: Intel Core 2 Duo CPU E7500 @ 2.93GHz (2 CPUs), ~2.9GHz Memory: 4096MB RAM Graphics Card: ASUS EAH5750 Series Primary Monitor: DELL E2210H Secondary (Faulty) Monitor: NEC LCD1712
You say that the problem occurs when you connect your secondary monitor up either solely, or as primary, but it also occurs when you have only the primary monitor connected Therefore I think the problem is inside your computer box not the monitor or cables.
I'd try another graphics card (the specs I have say the default the graphics is 1024MB NVIDIA GeForce GT220, but then they also say Win 7 Prof - http://www.pc-site.co.uk/reviews/dell-business/dell-vostro-230-mini-tower-desktop-review), either to the built in one (if your m/b has on-board graphics facility), or a different card (which may be the same model). Have a look in the BIOS too.
