I am relatively illiterate as to hardware. Needed a high resolution monitor to do my job. Bought an LG with 2560x1440. It's great. Then when I needed a new computer I bought a Dell Inspiron 3910 thinking that it would function like my old computer, but the highest resolution that the new Dell supports is 1920x1080 and now I have a mess. I don't want to have to buy another computer as this has the i7 chip and otherwise is good for what I need. Any suggestions?
