This thread interests me because I too need to decide if I should buy a 2K or 4K monitor. The main consideration for me are the reports that on a 4K monitor the LR text and tools appear too small. If possible I hope to run two monitors, one HD with the tools etc and one 2k or 4K with the image being edited. Does anyone know if this is possible - the only videos I can find pre-date 2K. Hope this is not considered thread hijacking. - and if it is I apologise. Thank you.
