Cho mình hỏi cách kiểm tra monitor cũ ?

Mình định mua một màn hình cũ, tuy nhiên mình không biết phải kiểm tra như thế nào thì mới biết được màn hình đó còn dùng có ổn không? bạn nào biết cách kiểm tra màn hình thì giúp mình với nhé (nếu có cách kiểm tra trực tiếp bằng windows thì càng tốt, còn nếu dùng phần mềm thì còn tốt hơn ..hì hì ).
Cám ơn các bạn rất nhiều !

Overview:
MonitorTest is a tool that allows users to investigate the quality and performance of their computer monitor or LCD flat panel screens. With more people spending more time in front of computer monitors it is important to purchase a quality monitor that will provide crisp, bright images, while reducing the strain on your eyes. MonitorTest displays a series of specially designed images on the screen at a variety of different resolutions and color depths to test for optimum visual performance. Each of 25 different test screens have been created to test a particular aspect of the monitors performance. As a monitor is often the most expensive part of a computer system, this type of testing is essential for the adjustment & selection of a quality monitor. Users would include computer repair centers, system integrators, quality assurance personnel, graphic designers and anyone that cares about the quality of their monitor. MonitorTest runs in Windows and will work at any resolution, aspect ratio and color depth supported by your monitor and graphics card.
