I have a Graphic Card ATI HD Radeon 5830 Monitor Benq 24 HD now the thing is whenever i connect Pc with HDMI cable and in Resolution 1980x1080 it Display doesn't stretch completely it just shows lil under size and lil flicker happens as if lines are coming n going but when i turned that into 1600x900 then problem seems go away , i tried all the settings in the monitor , got the latest drivers for ATI but the same issue seems keep happening , but when i use DVI connection it works flawlessly in all resolution ( i been using this for a long period and thought to try HDMI ) so just curious why it happening ? .
