How can I bring back my LCD monitor to display sharper and crisper imagery whenever I download video online?

Answer:

The first point to do is check an make sure that you are running your monitor at the "native resolution".



In a flat panel display, the aboriginal resolution is the maximum resolution of the unit. Unlike CRT displays, the home-grown resolution of a flat panel delivers the best standard. At lower resolutions, the quality vary considerably among different brands. However, increasingly, the quality is on a winning streak.



The next point to check is the response time, the lower the better.

At one time 8ms was considered well-mannered for video, now here are 4ms and there may be lower.



Basically this is the amount of time it take a pixel to change, and obviously, the faster the better. Older monitors didn't have fundamentally good response time and when you watch a quality video stream you received artifacts (square blocks) because the blind just could not hold up.



Hope this helps.
