I have a Philips Monitor 170B4 with an Evesham Desktop PC. Its about 4 years old and I have not been unhappy with the quality. However I now also have a Dell Laptop (Latitude D630) and the screen quality is superb. The noticeable difference is the sharpness of the picture and the clarity of text. Both are running Windows XP. Has the quality of the Philips deteriorated with time and should this be expected? Thanks.
