I got Gigabyte GA-H55N-USB3 motherboard with Intel® H55 Express Chipset on it. I equip it with i3 processor. Everything works great except that when I connect my Sony Bravia KDL-46W5500 TV to the HDMI I got oversized picture. I need to go to Advanced properties menu and downsize it to 60 by vertical and horisontal scaling. Why is this happening? A can see the sharpness lowerind with the resizing.
Please help and advise,
ps: Got the latest drivers, latest update for Windows 7 inc. SP1
Especially, make sure to be using the latest driver for the monitor that you connected, update the BIOS of your computer, test using the special driver posted there and use a direct connection between the computer and the TV.
I know it's a bit late as the question was a couple of months ago but thought I'd reply in case it's still not sorted or anyone finds the question while looking for a similar issue (like I did!). I had the same issue on my LG TV with a motherboard from the same Gigabyte series, had to set the scaling to 65% to see the whole screen. Turned out that the TV is set to 'overscan' by default, in my case choosing the 'just scan' option on the TV fixed it, I think Sony TVs simply refer to it as 'overscan' so try and find that option in your TV menus and turn it off, others may call it 1:1 pixel mapping. Hope this helps.
