Solidworks got extremely slow after changing the monitor. I used to use 23EA63 LG monitor (23 inch) and recently replaced this with 34" IPS LED UltraWide FHD FreeSync Monitor. Now my Solidworks 2019 is extremely slow with my computer. My old monitor's resolution was 1920 x 1080 and the new ultra-wide monitor requires 2560 x 1080. I even changed the resolution to 1920 x 1080 for the ultra-wide monitor as same as my old monitor but didn't improve any lagging issues. 

FYI, my computer is 

WIN10 OS, i7-8700K (overclocked 4.9 GHz), 32G ram (3000 Hz), Samsung 970 EVO SSD 1TB x 2, EVGA GeForce RTX 2080 Ti XC BLACK EDITION.

I don't know why this is happening and should I use a smaller old monitor that I used to use without any problems to prevent this lagging while working on my solidworks jobs? Any settings to change? Please help..
