My 24" cinema display is acting up. It keep having random black outs and sometimes it won't even come on during startup. I don't have applecare since I bought it used. It's a nice display when it works, but the unreliability is very annoying. I tried updating the firmware but it wouldn't take. I am using it with my 2010 Mac Pro, 5770, hooked up with a 10ft. mini display extension cable since my Mac Pro is down on the floor at the end of my desk. I also have an older 20" cinema display as a secondary monitor and it performs great, so I know it's not the graphics card. I am at my wits end with this. So I'm looking into other options. I want a nice 24" semi-professional display with at least 1920x1200 res. and around the same external dimensions as the ACD. Any good recommendations? NEC? Dell? Samsung? Thanks
