    Sounds like it might be dead pixels in the monitor...you have to get the monitor replaced if so.

I have (suddenly) a single dotted black line about a quarter wasy down my screen on laptop. Can I get rid of it?


Hello,

First, you need to verify if the dot is cause by faulty graphics chip/card or LCD/LED. To do this use external monitor, if you cant see dot on your external monitor then you have faulty LCD/LED if you see dot like in your laptop the you have graphics chip/card problem.

Black screen card


Make sure that you have the latest display (Graphic) driver installed on the comuter. If you are still facing this problem then it might be that your computer graphic card is old and does not support the required graphic resolution which is required to play this game.

You can try--
Most of the time DPI (Dot per inch) setting also fix this type of issue.
You can change the DPI settings in windows Xp by following these steps:
1. Click on Start then Control Panel.
2. If control panel is set at Classic View, then double-click on the Display icon
3. A box will pop up. Click on the Settings tab.
4. Click on Advanced.

Change the DPI setting to Normal size (96 DPI). You can also change the DPI size to any other value. Click OK and your computer will ask you to reboot your computer. Click Yes

Hi

What is the Resolution


Refers to the sharpness and clarity of an image. The term is most often used to describe monitors, printers, and bit-mapped graphic images. In the case of dot-matrix and laser printers, the resolution indicates the number of dots per inch. For example, a 300-dpi (dots per inch) printer is one that is capable of printing 300 distinct dots in a line 1 inch long. This means it can print 90,000 dots per square inch.
For graphics monitors, the screen resolution signifies the number of dots (pixels) on the entire screen. For example, a 640-by-480 pixel screen is capable of displaying 640 distinct dots on each of 480 lines, or about 300,000 pixels. This translates into different dpi measurements depending on the size of the screen. For example, a 15-inch VGA monitor (640x480) displays about 50 dots per inch.
Printers, monitors, scanners, and other I/O devices are often classified as high resolution, medium resolution, or low resolution. The actual resolution ranges for each of these grades is constantly shifting as the technology improves.



Solution :

1.
If you not get the proper video image in your screen that mean you have remove the driver of video, for installation the driver, put the Driver -CD in rom, and start the setup is simple set you get the driver.after installing the driver restart your PC
2.
If you change any display setting then also you get the occur.for set the resolution go to the control panel and select the Display and go to setting tab set the ' Screen resolution" as before.

3.
If you still not get the display then open you PC and remove the RAM and put again,and try again.


God Luck

Black screen white dots


This is likely due to Hardware Failure. Your GPU (Graphics Processing Unit) has likely overheated to the extent of artifacting which is when the device begins to have trouble rendering objects and images and crashes constantly. The only viable solution is to send it in if you still have warranty, Otherwise, you'll have to either buy a new Xbox 360 or send it in for repairs from microsoft.

Hope this helps.

Black dots during gameplay only on 360


I had this problem with my very first Xbox 360. It started showing little white dots instead of black though. I just dealt with it for a while, and it finally got to the point where it would fill up the screen fully, to where I could only see my gun in Halo 3 and that was about it. I was forced to call Microsoft and have them fix it.

Coloured And Dotted Lines Across My Screen


Firstly, start your pc in safe mode (f8) on boot up. This will start your pc in vga mode, and hopefully the lines are still there, which will indicate a faulty graphics card, if they aren't it may be a problem driver. If no lines, go to Add/remove programmes and uninstal your graphics driver. Re boot pc then when it finds your card make sure you point Windows to the folder in which you have saved the driver files. The driver should then install, see if any change. You may have to try some older drivers, as Nvidia can be awkward at times. I have had varying problems with Nvidia and replaced with ATI cards with no problems.
