Thank you. I forgot to ask this question. Do I need to uninstall my pre-existing integrated video driver? When I checked my computer device adaptor, the pre-existing integrated graphic card is not shown although physically it is still there. I only see the HD 4350 graphic card. The monitor appears to work fine with max resolution of 1900 x 1200. Does it matter or does it improve my graphic function by deleting the pre-existing integrated graphic driver from control panel? Please advise.
