Dealing with this 720p issue is kind of a nightmare. The fix that uses regedit and has you alter the Display1_DownscalingSuppored only works on Intel series GPUs. Don't bother wasting your till because you'll just get yourself mad trying to figure it out. I've got a Vizio TV and the it specifically states on their website that it supports native 1366x768 resolution. So then why doesn't it show up in the Display Resolution settings??? Its because of the GPU Scaling feature. This feature overrides the monitor's accepted resolution settings for Windows. To disable this, open up Catalyst (right click on desktop background and its the top icon. Its been renamed on APU systems to AMD VISION) and navigate to "My Digital Flat-Panels, then Properties(Digital Flat-Panel), You'll see a checkbox in the Image Scaling box; uncheck that and apply the settings. Now you should be able to change your display settings to 1280x768.... 1366x768 still isn't showing up but you can use apps that require 768p now. There is one caveat, GPU Scaling helps get rid of over-scanning, so you'll notice that there is some black around the corner of the screen. This is where your TV is under control of the situation. I had to set my TV to Wide Screen mode... you have to look in your TV manual or poke around the menus to find the settings. You might not even have to deal with it. Anyways, hope this helps.
