Monitor Displaying odd grid-like pattern. It started yesterday when I booted up the computer. I have a screenshot if needed.

please tell what you are doing first
my wild guess is this oddly named monitor has Its OWN BUTTONS LOCKED THAT IT?
if yes this is covered in the manual.
lost that? google "Asus xg27v manual.... bingo
there are no standards here for OSD lock we call it.
but holding the actual button on the monitor marked menu. for 10 seconds unlocks many brands of monitor.
i cant read it for you , Im near off the grid on vacation, limited data.
but you can.

The monitor appears to be DVI capable, (White connector with a grid pattern). You will need to connect the monitor to the computer using a DVI cable (White connector with grid pattern and plus sign shape on one side). If your computer is not capable of connecting to a DVI monitor check to see if the monitor has a Blue VGA (Blue Zig Zag Openings) and connect it with a VGA cable. If your monitor only has the white DVI connector and your computer only has a Blue VGA connector you will need to go to the store (Best Buy, Walmart, Etc) to buy a small adapter that will convert DVI to VGA. If you ask someone for a DVI to VGA adapter they will know what you are talking about. I hope this helps.

The best way to check the monitor is to try it in BIOS.

Turn on the computer, Press F10 while computer is booting and check if it gives you the same issue is System BIOS also

If it is the same in BIOS then you do not have to check anything on your computer besides replacing the Monitor

if the system unit is working while displaying that on the screen.try this:start the system unit a fresh and quickly press F8 button on the keyboard immediately the computer start up for 5-6 times simultaneously and select "boot with safe mode" then after booting u can now readjust the screen resolution from the control panel

Sounds like you have some radio frequency interference from some electronic device such as a TV or another computer. Try a new vvideo lead with better screening. The fact that it is in a grid pattern indicates a steady frequency.

Being able to open a cd or dvd drive only requires power to be going to that unit. The following assumes your monitor is working but is just not displaying anything.

What you are describing sounds like you are having a hardware or BIOS issue or some sort. This doesn't necessarily mean a component fried or what not, it can just be a misconfiguration.

The fun part is tracking down what it might be, trial and error or educated guesses is all you have.

If you have added anything new to your computer recently, I would look there first. Recent means in the last few days.

Next I would unhook anything connected externally to the computer...minus your monitor. Yes this even means your mouse and keyboard. If you are on a wired network/internet, also disconnect that from your computer. After everything is disconnected, try booting the computer up. If you now see your monitor displaying, then one of the components you removed is the cause of your problem. Plug them in one by one and find which one causes your problem to come back.

I forgot to mention a BIOS reset, remove the BIOS battery for a few seconds while your computer is unplugged from the wall. The battery looks like a bigger watch battery, thin, circle with about a half inch diameter. It will be on your motherboard.

If none of the above worked, then you are going to need to open your computer case up and start looking inside. Also at this point, having another working computer around will help tremendously. First thing I would do is make sure ALL connections inside computer are nice and snug. So check all your cables and hardware that plugs into motherboard. After done, try booting up again.

Now you need to remove any add-on cards from your computer. Things like ethernet card, wireless card or whatever else you might have installed. Leave the video card installed (if you are not using onbaord/integrated video). Try booting up again.

If still not working, then this is the time I would start swapping components between computers. First I would try the monitor on a different computer and then I would try the video card in another computer. Next thing I would check is the RAM, this can be tricky if the working computer you have around does not accept that type of RAM. But you could always buy RAM and take it back after you are done with it, sometimes having to pay a small restocking fee. If you have more than one stick of RAM, remove the others and try booting with a single stick installed. Then if still no boot, install one of the other sticks instead...but keeping it at a single stick installed. I would not bother trying the hard drives in another computer, have never seen a faulty hard drive with the correct jumper settings stop a computer from displaying anything on the monitor. But if you feel the need to test them, one less possibility.

There is also the odd chance your PSU (Power Supply Unit) is not acting like it should be. You can either do a swap from a working computer, buy a new one and take it back or research on the net how to test one while it is not in a computer.

If none of this changed anything, then I would start looking at the motherboard or processor as the culprit. At this point I just replace the motherboard and try again, then I do the same with the processor if the mobo swap did nothing.

I have never once seen a computer not work after this process for the problem you are describing.

Hope this helps.

Try using a diffrent computer on this and see if its not the video card doing it or if not its the controller board inside that connect to the video card that would need to be replaced at this time, if there are no dead or stuck pixels it might be worth replacing rather then buying a new one.


Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

It sounds like the computer is trying to use a resolution that the monitor cannot handle. Boot into safe mode by pressing the f8 key during boot up and select safe mode. Once booted, right click on the desktop and select properties. In settings lower the resolution by moving the bar to the left and reboot.

I would move it all the way down, you can then move it up a step at a time once you are in normal mode again.

Hope this helps

Solution: boot your system to safe mode and then delete or uninstall the VGA driver in the device manager.

to to this; when booting press " F8" to select the boot mode.

and then after booting; click start , point "my computer" then right click "properties".

click "hardware" tab, "DEvice manager" tab and then in the . click + sign of the Dispaly adapter.

then unistall the driver.

after unistalling restart the system to normal mode.

if the system need and installation driver you should supply it.

sir,,,,just adjust its focus,,,,,or maybe the lcd is damage and u need to replace it,,,thnkss and hope to help you??
