Test your computer with another monitor, if it works, then the new monitor is defective.

Did you have a power outage?  Surge perhaps?\nSomething took out the power supply right?\nIf you aren't getting any kind of beep code or anything and everything seems to be reacting normally.  The very first thing I would do is check to make sure the monitor didn't get toasted!\nAlways verify the monitor isn't fried before you go to the MB and other internal parts of the pc for troubleshooting a video related issue.  Did you get responses from the hard disk, or cd rom after the power supply was replaced?

could be the graphics card, try a different driver, also try a different power cable for the monitor, very unlikely it is the cable but worth a try. If you have a nother graphics card you could try then try that, if problem still persists then it is your monitor, may still be under warranty, you may want to check that.

Is the LED of the monitor glowing? Is it green or a different color? Is it steady or blinking?\nIf its a relatively new monitor, a message will be displayed if the signal cable is disconnected. If the LED is blinking, then the monitor is connected but not receiving signal from the system. If the LED is steady green, try increasing brightness and contrast. Do you see the monitor's onscreen menu?\nIf the monitor is older than 3 / 4 years you can expect a breakdown.

I'm assuming you know HOW to set resolution, so theres three possibilities:\n\n1) Video Card does not handle larger resolutions\n2) Monitor does not handle larger resolutions\n3) Video Drivers do not handle larger resolutions\n\nTry to download the newest video drivers first. Do a Yahoo! search for "<video card name> drivers", and find the manufacturers website. Download and install the newest possible.\n\nIf that doesn't help, your hardware is the problem. If your monitor is small and old, it is very likely the problem. Check the documentation if you still have it.\n\nOtherwisw it will be the video card. Again, check it's documentation for limits. You may have to replace this and/or the monitor.

It sounds like the connector from the monitor to the back of your computer isn't completely attached, or you may have bent one of the pins on the connector.  Remove it, check for bent pins and -carefully- straighten any that may be damaged, then reconnect.

normally if you have a yellow led, as the monitor says it's in standby mode.\n\nIf you have just turned your computer on and the monitor does not change from the standby mode then check:\n\n1) Your vga cable from your monitor is firmly in the back of the pc.\n\n2) Try your monitor on a different computer - see if you get the same results.\n\n2) Try installing a new video card on your computer. Do this only if 1 or 2 does not work.\n\nA lot of the time the reason the monitor does not turn on is because usually the motherboard has died or the graphic card has died.

it shouldn't do that, try to unplug the monitor from the pc and then plug it back

multiple things could be the problem, you'll have to do some troubleshooting.\n\nFirst I would check that the monitor is plugged in correctly and powered up. There is a plug, ususlly blue, plugged into the back of the tower and leading to the monitor. two manual screws hold it in place. untighten the screws to see 15 pins. make sure all pins are intact and not bent. plug it back in tighten screws, power on pc, give it a second and see if it works. if not... \nNext I would check the monitor on another computer or try another monitor on the first computer. If the monitor is not fried, its likely you have a video problem. \nIf its a video problem, you are going to need to get a video card. ask at your local computer store. buy, or borrow one from a friend for testing. you might want to open your tower first to see what kind you need.\nGet some canned air and a small screw driver. \nBefore you open the case check to see if you have onboard video or a video card. You can do this by seeing if the Video plug(vga 15 pin same as before) is located behind your I/O shield (where the printer port, mouse keyboard and usb ports are) which would mean its onboard. If it is in one of the long horizontal slots, its a card. \n\nunattach the VGA cable and Open the case. Its usally either a screw on the back and then sliding it off or a handle that you can use to pop it off.\nBefore touching anything make sure the power is off, but the computer is still plugged in and put a hand on the metel case to ground any static electricity in your body. esd can damage your mobo. \nplug your nose and close your eyes and blow out that dusty mess with the canned air.  \ninside is a mess of cables that can be scary but bare with me you are looking for a speciffic thing. you should see the power supply with all the multicolored cables running to the cd rom hard drive and other stuff. Then there is likely some IDE cables (flat ribbon cables connecting the motherboard to the hard drive and cdrom.) on the mother board there will be some slots (usually white) that correspond to the slots on the back of the tower. in these may be the video card, if so you have a PCI video card. If the card is plugged into a similar slot that is shorter, set back more, closer to the inside of the motherboard and probably brown or blue (also corresponds to a slot in the case usually the highest slot), it is AGP. If you have onboard video just see if you have an AGP port so you can get an agp video card. (note there is a new technology called PCI express but unlees you bought your computer in the last 6 months don't worry. ill assume you haven't otherwise you'd just use your warrenty)  \nso get yourself the correct video card (agp or pci agp is better).\nPull the old one out (unless you have onboard video) \nThe long piece of chrome metel attached to the video card is bent at the edge and there is a screw in the top. (or there is a clip over all your expansion cards) unscrew or take this loose. agp cards sometimes have a plastic clip on the back to keep them from popping out, unclip this.\npull strait up on the card, some force may be required but don't break it. handle all circuit cards by thier edges only as much as possible to avoid esd. \nUnpackage the new (or Known good) video card and insert it the same way you pulled the old one out. make sure that it is seated well. put the screw or clip back in place and close up the case. \nattach the cable to a known good monitor and power up.\n\nif this doesn't change anything, its likely that your motherboard is freid. if this is that case you will need to have a professional work on it for you or just buy a new pc.\ngood luck.

if your Video card built inside the mother board does not have any other plug than the monitor output, simply buy a converter to adjust the plug. if you do have any plugs than can be used as out put, plug it in then go to Disply options and switch to the other display adapter, then click on ( make this my primery display ) or such a thing

The monitor is probably not the problem. Find out what video card you actually have, (on board or PCI) and install the correct driver.  The actual monitor has very little effect on how the visual effects render.

It sounds as though you may have bent a pin when you hooked up the monitor cable to the computer. Try unhooking it and look in the 15 pin plug. THe pins are very thin and can bend easily. If you have a bent pin, use a pair of thin needle nose pliers the straighten it out. If this is not the case, there is a good chance that you bought a bad monitor. Unfornuatly all you can do for that is to take it back and get another. Sorry that I am not more help.

Is the monitor plugged in all the way, it may be loose.\nYour video card may have went out.\nYour monitor could have went out.

It may be the display adaptor hardware in your PC? I assume its integrated into motherboard so do you have (or can borrow) a PCI display adaptor to test this theory? or better yet another computer or laptop you can test the monitor with to see if its the problem or its your PC... Good luck!

Start with the basics, first.\n1. Is the monitor plugged in to a power source?\n2. Is the little green light on indicating the monitor is on?\n3. If it is on, do you have another computer that you could test the monitor with?  You want to make sure before you go replacing your video card that it's not your monitor.\n4. If it's not your monitor, do you have another monitor to can test your computer?\n5. If the 2nd monitor doesn't work with your computer, check to make sure you haven't wiggled you video card lose.  Be sure to turn the power off to your PC, unplug it from the wall and wear an anti-static wrist band before toying with the insides of your computer.\n\n-PCI video cards are notoriuos for coming lose if they aren't held in place with the set screw.  AGP cards not so much but still can come lose.  \n\n-Take a look at the card where is plugs into the motherboard. The card itself has many copper connectors that you shouldn't see when it's properly installed.  If it's in there slightly ascew you may see these copper strips more easily on one side of the video card that the other.  If that's the case... firmly reseat the card.

If it is an older monitor, your picture tube may have gone bad (if so, you might as well throw it away), if it is new, i would supect the cble connecting the monitor and the computer is dammaged, or the connector at the end. Other than that, unless you have electronics expirience, thier is probably nothing inside it that is broken, that you could fix.

Sounds like it could be a short in the wiring to the monitor. If it changes as you slowly open or close the monitor, then that is it. If it is visible before windows boots up, then that is it as well.
