I am looking at the ASUS VH236Hp for a new monitor, But there are a couple things I would like to know about it that nobody is listing. For one, when it is running at 1920x1080 what are the available refresh rates? 60Hz? 72Hz? 75Hz? Because currently I am using a SAMSUNG SyncMaster 220wm which has a 'recommended resolution' of 1680x1050 at 60Hz, I ended up having to downsize it to 1280x1024 at 75Hz because I wanted the faster refresh rate, Thank you for the info!
