Monitor Do Not Work In VGA Mode?
Sep 18, 2011
when I made a boot defragmentation of C:/, after 5 minutes my monitor showed up "no video imput" and got in stand-by. This was frustating: I had to wait until the system started to beep, and reboot... And second, I wanted to find some settings in the BIOS to fix this problem, I started to search, and after 3 or 4 minutes... the same thing: "no video imput", and a black screen... How can I get my monitor to work in vga mode also? Or is something else here? Some infos: I have a HP XW-4400 Workstation, it comes with pre-installed XP, but for two years I upgrade it to Windows 7 Pro. I installed all the drivers for Windows 7 from the HP site, because on my recovery CD are only the drivers for XP. Some of the Windows 7 drivers failed to install... but all that I could install, I installed. I tried to find a driver for the "on-board vga intel video driver", but nothing to find on the HP site... I already searched everywhere on the Windows 7, and I put all the settings for monitor and video to sleep "never", but with no change when it comes to boot operations. It is very risky to not see what is going on when you defragment on boot, or when you are in the BIOS settings...

im having problems with my monitor, it doesnt want to get out of sleep mode. Right now I have the comp apart which is no problem for me to put it back together. Im assuming its either the battery not giving enough power or the connection where you plug the monitor into is bad.

I have a Dell Studio XPS435 MT running Windows 7. For the past six months I noticed that when waking the computer from sleep mode, occasionally the monitor would not wake up and I would have to reboot. It got worse and worse until now it will never wake up without rebooting. I also noticed when I reboot, if I don't wait a few seconds for the computer noises to stop and immediately press the power button; the computer starts beeping loudly and nothing works. I have to manually shut it down and wait about 30-40 seconds to reboot.

sometimes not all the time after my pc has been in sleep mode, the monitors dont come back on, i can see the pc wakes up but the monitors stay black and so far the only way ive got it to work is to power off and reboot.
all my drivers are upto date what could be causing this i dont realy want to disable the sleep mode?

My computer monitor won't wake up from sleep mode. The power light flashed blue like it is asleep but when I hit the keyboard or click the mouse nothing happens. I even restarted the computer and tested to see if the wires were bed or loose and that didn't help either. I switched out the monitor and the new one works on the computer so it seems it is something with the monitor.

I am not sure if this is in the correct section of the forums, so apologies if it isnt! I have a GTX 660ti. When plugged into my 1080p television, it works perfectly. However, when I plug in my 17" dell flatpanel, it says "not supported" across the screen. Is my GPU too advanced for me to use a small monitor? I have tried changing my resolution much lower, then turning the pc off, then plugging in the 17", still not supported. Is there something I have to do in bios?

Got a PC with Nvidia GeForce 6150 graphics card with no overclocking. Sometimes the monitor loses signal and does not work. Sometimes it works just fine. I've tried different VGA cable and different monitor, situation didn't change. I've got 4 different connectors.
- 1 VGA and DVI on Nvidia
- 1 VGA and DVI built in into motherboard.
Sometimes, when the Nvidia doesn't work, I connect to built-in card and monitor starts working. Next time when it's out, I connect back to Nvidia. There have been situations when only one of the four connectors is working. This means that on one graphics card there may be only one connector which is functioning. I don't get this. Problem isn't in the display nor the cable. It also doesn't seem to be in the graphics card as the built-in connectors aren't fully functional neither.

I have an HP proBook 4440s and a external HP S2031 monitor. I can get the extended monitor feature to work outside of the VPN. Once I go into the VPN the only thing I can do is move the entire VPN to either screen. I can't share anything within the VPN such as word, excel, or outlook. how I can move items within the VPN from screen to screen?

The thread title about sums it up! When I try to wake my computer from sleep mode, my monitor gets no signal/is black. The "rest" of the computer seems to wake up just fine.
The monitor was working fine with Windows Server 2008, after sleep mode, but I just recently upgraded to windows 7.
I have already tried: displayswitch /extend displayswitch /internal in a .bat file
using "Hibernate Trigger", "Power Triggers" and Windows task sheduler.
Doesn't work at all for me (I've got Windows 7 Proffesional 32-bit Service Pack 1)

Is there a way to force Windows to use the default monitor settings as used in Safe Mode, but when running in normal mode? My Nvidia GE 6100 graphics began scrambling the screen. Safe mode works ok, but on normal startup, the screen is scrambled or goes fuzzy and everything freezes. I think it's a hardware problem (it started after I added memory) but I want to keep running until it can be fixed. I have updated the drivers but it did not change anything. I tried deleting the Nvidia driver, but Windows keeps finding more.

I left my computer running overnight as I usually do. When I went back to it this morning, it was stuck in power saving mode. When I rebooted, everything looked fine and the windows logo loaded but when I reached the login screen it went directly to Power Saving mode and got stuck there.
I am posting this from Safe Mode with Networking.

so the Windows 7 Ultimate 64bit install is fresh, and all the drivers are the latest available. I have updated my mobo's bios to the latest version through Asus' "AI Suite II" which makes things very simple. I want my PC to be able to go into sleep mode but I don't want to have to force shutdown every time it goes into sleep mode after a time span. For some reason if I wake my PC after its been in sleep mode for a short period everything turns back on just fine... I know there might be a solution through the configuration panel

New Build Asus M5A88-M EVO
Phenom II x6 1055T 2.8Ghz
Samsung 840 series 64Bb SSD
Radeon HD5570
Win7 Professional 64 Bit
Annoying intemittent fault whereby the monitor is incorrectly detected as a generic model instead of an LG L192WS and the screen resolution changes to a lower setting which loses a large percentage of the desktop. I've updated to the latest AMD drivers as that seemed to work for others with a similar problem but to no avail. it takes 5 mouse clicks to open desktop and reset the display to the correct one, but after spending quite a bit to speed up my system I begrudge the time!

This problem only occurs during W7 startup, after the "Starting Windows" logo screen. My display then goes black. A few seconds later the status light on the monitor changes color and it displays "Entering Power Save Mode". Several seconds after that, the display wakes up, showing me the user login screen. Then, all is well until next startup.
My PC is a new build:
Intel i5 2500K CPU, has onboard GPU (unused)
Mobo is ASRock Z77 Extreme4
GPU is a GeForce GTX 560
(known good) Dell monitor, ST2220
I've tried different monitors and tried switching to the other DVI connector on the GPU, no joy. Removed & reseated the GPU, no luck. Don't see any BIOS or Windows settings that seem to apply here. should I go ahead and call EVGA support for my GPU? Reaching the end of my rope, as I can't seem to find anyone else with this particular problem on the Inter-Webs.

I have ordered a PC (Dell Studio XPS 8100, 8GB Ram, Nvidia GeForce 240, Intel Core i5 750) and would like to use my existing BenQ FP93E S monitor with it as I am very happy with this monitor. Apparently the BenQ is compatible with Vista but I cannot find out whether it is compatible with Windows 7. I intend connecting via DVI-D.

I was rebuilding my computer bit by bit after my old one died on me. I recently purchased a motherboard/cpu and I used an old harddrive with windows xp on it and my old video card from my previous pc.Everything worked fine, all usb ports were up and running, monitor worked great. Than I went to install Windows 7 on my computer from a usb thumb-drive. Everything went smoothly until I got the the first restart. When the computer turned on again, all fans were turning, hard drive was spinning, and led lights turned on but my monitor went black saying no connection, and none of my usb ports work (no lights on my keyboard or mouse).
My computer specs are:
Motherboard: AsRock 970 Extreme3
CPU: AMD-FX 4100
Graphic Card: Zotac GeForce 9500GT
Ram: 2, 4GB (8GB total) Corsair Vengeance DDR3
HDD: Seagate Barracuda 7200.7
Monitor: Asus VH198T

I have an Acer Aspire 5741-5979 using a graphics card of Intel (R) graphics. This is a new issue I have had recently. I used to connect an external monitor to my laptop, and it worked fine. The issue is that the laptop still detects the external monitor but the external monitor does not receive a signal when I plug it in the VGA (blue trapezoid connector) have played around with the display options an exhausting amount of times and nothing works there. I tried what worked before (extending the display) and trying to clone it. I thought it might be a driver issue and I reinstalled the driver, but this didn't seem to help either. I have used many monitors when it worked, and also tried different monitors after it stopped working to no avail

When I'm using the computer...at very random times, the screen goes black, then a blue window pops up telling me it has gone into power safe mode. I'm assuming, when this happens the computer freezes because, when I hit the hot key I set up on my keyboard to shut down, nothing happens...So, the only option I have is unplugging or holding the power button until the machine shuts off. Then, I restart.When I try my hotkey for shut down during normal usage, it works just fine, but not when the monitor decides to take a coffee break and leave me hanging.If I was doing something lame, like work, it wouldn't be so bad, but right in the middle of online gaming??? COME ON!To sneak another question in...which might, very well, be linked to the issue above, the computer freezes at random times as well. Especially, at startup. I have to hold the power button 3 or 4 times...with beep beep beeps...until it finally decides to show for work and do what its job description states.

The monitor seems to go into power saving mode when entering/exiting a game such as a game in steam. (But it doesn't happen every time) the only way to get it out is hard restart. Yes I've tried other monitors, as well as display drivers, and there also seems to be nothing wrong in the Bios.

I have a video card that I want to install in my computer running Win 7 Professional. The card is only supported with xp drivers. Win 7 Professional has XP MODE where users can operate in an Xp environment. Can I use my video card in XP mode? Even if it is not the primary video card perhaps?

I've bough a Dell Inspiron 1564 with Windows 7 home premium x64 last month and everything was fine until a few days ago, when sleep mode stopped working. When I close my lid and open it up after some time there are 2 things that might happen:
1. The screen is just black, all the buttons are lit, I hear the fan, but no reaction at all. So I just forcibly turn off and turn it on again.
2. After opening the lid, nothing happens, when I try to turn it on, it loads up, but informs me that windows has not shut down properly last time (or something like that).
