my tv's native res is 1366x768 but windows recomends 1360x768 its advertised as having 1080i 720p, but if i try to set 1080i i get thses weird fuzzy verticle lines on ground textures that move up or down when moving, seen best on dark textures and i only really notice it on the ground wich i dont get with 1360x768, i dont really understand why that is tbh, also if i try to set as 1080i, i have to use gpu scaling to make it fit the desktop. in my tv manual it says to connect tv to pc using vga, im using hdmi, could this be why, it says to connect using vga and set res to 1366x768. thing is if i try setting tv to that, it only lets me have 30hz wich it says in ctalyst control centre, but my tv says its 60hz, in the manual it says, try 1366x768 at either 50hz, 60hz, or 75hz, but catalyst only lets me have 30hz or 60 hz according to my tv, if i try changing the hz for 1366x768 it just changes the res to something lower, any ideas why that is, got any techy people in here?
