Dual Monitors or 1 big one????

I use two LG 22.5" monitors and editing wise I cant work with them for much longer I have had them for a couple of months now setup on a dual monitor clamps looks good but I cant get use to the middle crack…so much so im going to get rid of them on eBay and go back to one large monitor.editing time has near doubled I just cant work as fast with them.
