Get rid of this model!!!! The Hannspree and Toshiba models used a TFT LCD screen from a chinese manufacturer that has put out faulty components for the last 3 years. The Problem is in the way the Active Matrix Screen was manufactured. I would recommend you return this item immediately to the place where you purchased it and pick a different brand; also stay away from Westinghouse!
Monitors mix the 3 "primary" colours, in various proportions, to produce all other colours.
Mix equal parts of all 3 colours, and you get WHITE.
Mix equal parts of only 2 colours, and you get YELLOW.
1. your computer's video-card is not sending the 3rd colour;
2. your video-cable between the computer and the monitor is broken, and is not transmitting the 3rd colour;
3. your video-cable is not TIGHTLY connected at each end;
4. the electronics inside the monitor that SHOULD be producing the 3rd colour have failed.
Try connecting the monitor to a different computer, with the same video-cable. If it works correctly, your video-card is the problem.
Try connecting the monitor with a different video-cable, to see if replacing the cable fixes the problem.
Try connecting the monitor to a different computer, with a different video-cable. If it still is incorrect, then the monitor needs repair/replacement.
Colours on the screen are generated by "mixing" the 3 primary colours.
Of the primary colours is RED.
So, your LCD monitor is not receiving signals from your computer,
specifying the other two primary colours.
Check the data-cable between your computer and your monitor,
to ensure that the connections are tight at both ends.
Try a different data-cable.
Try your monitor on a different computer, with two different data-cables.
Try a different monitor on your computer.
It could be the video-card inside your computer is failing to "send" one or two of the primary colours.
Here is a list of reasons why colours on electronic designs might differ from printed designs:
Monitors work in the RGB (Red,Green,Blue) colour space while printers use the CMYK (Cyan, Magenta, Yellow and Black) colour space. Designs look fine on a monitor if they are designed in RGB to begin with. Converting them to CMYK might make them look odd on screen, but they will print correctly, to a certain measure. It is difficult to sign of an image file that is currently in CMYK mode while viewing with an RGB monitor.
Monitor settings differ. The designer was sitting in a darkish room when choosing the blue and his blue looks vibrant. The client was viewing the same design in a well-lit room, making the blue seem lighter. The designer uses an LCD display and the client uses a CRT monitor and the vibrancy differs. The contrast and saturation settings on each monitor might differ as well, rendering the blue with different values.
Each printer in the world prints colour slightly different. Sometimes it is really obvious and sometimes it is almost impossible to see the difference. Normal desktop printers are definitely not something to do colour proofing with. If you print the design out on your desktop printer then a slight shortage on any of the colours will make the colour come out wrong. There are a lot of factors that can influence even the most expensive printing equipment. These include altitude, humidity, the current heat of the printer, age of the printer, quality of ink, the paper that is being used, special coatings on the paper etc. Even viewing the same printed material in different lighting conditions may make the colour seem different.
Tips on getting the most accurate colour Go to your nearest printer company and ask to see their Pantone colour matching system. Each colour in the Pantone chart has a matching number. Most design applications have the same Pantone charts built in so that colour matching is easy. Read up on Pantone at Wikipedia. Make sure that the file is converted to CMYK (If not designed in it originally) before sending it to print. Some printer companies might ask for colour separation prints which the leading design packages can produce. It is also important for the designer to choose the correct colour management profile in the design package.
My first guess is that the screen circuitry has gone bad - although fixable. Use an external monitor to verify this. If the external monitor is fine then the screen circuitry is bad, if the external screen shows the same problem then the video chip or associated circuitry has gone bad. My company fixes these all the time.
hi im wesley. please make sure that you keep speakers and things like that away from your screen and switch your screen off and plug it out for a few hours if it duznt come right its not magnet that caused it it might be settings of your vga card.
The screen colour changing is apparently an auto test procedure on the monitor and was prompted by a fault with the monitor not automatically shutting down when the computer is shut down. The settings on the monitor have been adjusted to rectify this and the problem is now gone.
