I've been using a viewsonic vg2230wm for the past 6 years. I believe it came out in 06. What have I been missing for image quality? Has anyone upgraded from a monitor like mine to say a Asus VG236H or Samsung S23A700D? My budget is around $300 but only want upgrade if its really worth it. my current monitor hasn't had a issue or a dead pixel. My budget wouldn't allow for a 120hz monitor past 1080p and even if it did, video card requirements for running high res go way up. I'll be using the monitor for mostly gaming.
