I have got a monitor which used to work fine few days before it turned out to be more colourful. that is it now shows some green colour to right corner orange to other corner etc. the colours are like big xpots. I am sure that it is not a software or video card problem because i tried the monitor on an external tv kit which doesnt' any cpu, hdd, or any thingj just the tv kit and there also it shows big spots. I think this much info is enough to answer this question. But can ask more, I dont know the model but a ZenithPC logo is on the monitor and inside the monitor there is JVC shown on some part and CHUNGWA is shown on the tube. Waiting for reply please help.
