I just dropped off my 27" iMac at the post office and it's on the way to a (hopefully) happy new owner. Until I purchase a Mac Mini and a new screen, I've hooked up my work assigned MBP to a LG 27UD68P 4K monitor. I didn't know what I had until it was gone. The iMac's 27" screen was amazing and it has spoiled me! As I'm typing this staring at the 4K monitor, I can't help but think "What have I done???" It isn't as sharp and everything feels dull. I hope that within time, I will be able to adjust to my new reality. One of the reasons I sold my 27" iMac was because I wanted a large 43" monitor or TV as my display, operating in full 4K resolution for the extra real estate. Having just experienced the before and after of the iMac's 27" 5K screen, I am looking for help choosing a new monitor that will be somewhat close to the brightness and the punch of the iMac's screen. I know it won't be possible to get the same quality, but please help me choose one that will come the closest. My criteria is that it must be large enough to run it at full 4K resolution without text being too small. I do not want to go bigger than 43" as it be will be too big on my desk. My budget is around $600. I've narrowed it down to these 3 contenders. If you have other suggestions, please let me know. Link: LG 43UD79-B Link: Sonly KD43X720E (Is there a newer model out? B&H is saying it's discontinued) Link: Samsung UN43NU7100 If there are current owners of the above, I'd really appreciate feedback. I think all 3 above have acceptable input lag. I'm looking for text quality and brightness. I don't care about color accuracy. Thanks!
