i am thinking of upgrading both monitors and personal computers. do any of you use ultrawide 34" monitors and have recommendations? i know Dell doesn't release its Dell Display Monitor software/drivers for Macs, and LG appears to support Macs with LG Screen Split. i'm not sure how much this matters -- is there Mac OS software that isn't proprietary for window layout? is it best to just avoid Dell because they don't support Macs?
