This is my monitor(graphics) card information
And now my laptop (DELL-Inspiron-N4050) has HD resolution (1366x768):
dimensions: 1366x768 pixels (361x203 millimeters)
And I wanna know that how can I upgrade it FHD And I googled what max resolution supports by my monitor(graphics) card. So I find this site (offical site of amd):
It says it support up to
Max resolution: 2048x1536 but Currently I used resolution is almost 50% lower than the max resolution.
How can I solve this issue. Caused by driver? or what? if the caused by driver how can I update driver?
And my OS information is like that : lsb_release -a
