i have an acer monitor from 4 years ago
IPS 1920x1200 27", paid 750$ and it still has zero dead pixels, great color and viewing angles. the only drawback might be its not as fast as current, but ive never been bothered by a few ms difference. a 24" of the same quality is still going for nearly 500$ today, so i guess it was a great investment.

how many companies even make their own LCD panels anyway?
