Im using MacBook Pro Retina 15 - late 2015 model. Im a filmmaker who does the job on Final Cut Pro and my eyes bleed working on the MacBook Pro. I need a bigger display to work, so that I dont have to cramp in each edit and mouse movements. I started looking at, http://www.lg.com/us/monitors/lg-34UC98-W-ultrawide-monitor But later found that, the retina doesnt look proper on the display, even if its 3440x1440 resolution monitor. Now, there is not a single 4K monitor of that width, so I ended up checking this two displays which are same price and does 4K output as well, http://www.lg.com/in/monitors/lg-31MU97 http://accessories.us.dell.com/sna/productdetail.aspx?c=us&cs=04&l=en&sku=210-AHSQ Now the LG is 17:9 and 31 inch, 4096 x 2160 Dell is 16:9 and 43 inch, 3840 x 2160 Now, Im confused which display to take, so that I dont have to upscale downscale anything and everything just same as what it looks on retina. Suggestions please ?
