Every one who is a bit constrained on the budget is
looking for a great looking used monitor. Unfortunately most of these
used monitors are not good as new. The trick is to buy the one with
least ammount of flaws. Here are some tips to help you get the best
deal.
1. Always use your computer and its graphics card to
check out the monitors. Only then can u truly judge the diffrence in
image quality.
2. Use still pictures to judge the image quality. Films and games are
the worst criteria for judging the monitor, as constant movement makes
it impossible for the naked eye to detect flaws on the screen.
3. Use a program called power strip (www.entechtaiwan.com/ps.htm);
it allow u to push the maximum resolutions on any monitors at the
highest supported refresh rates. This will allow you to judge whether
certain modes are wholly supported or not.
4. Look closely at an open document's words/fonts. If they are too
blury, it is strongly suggested that u skip the monitor as using it for
more than movie viewing will be headache.
5. Try to squeeze in a day's checking warranty. Also make sure you buy
from a bigger Shop with larger stocks, so that you have a wider range
for selection.
