I purchased my Envision EN-LM500 LCD monitor several weeks ago at a garage sale and tried it out later that day on an older Pentium II desktop. The seller told me he had originally purchased it from his place of business, so it seems to have held up well under consistent use. The picture quality is good, but the image seems to have a slightly white cast even after adjustment. The control buttons are located on the front to make it easy to adjust the visual display, and the menus are intuitive enough that it can be done easily without a user's manual. At 15.1 inches this monitor is smaller than many other LCD monitors on the market, but it's been helpful in my case. Overall, I'm satisfied with this monitor. I'd recommend it to those trying to upgrade an older, less powerful computer on a budget.
