For about a month now, I've been using my TV as a second monitor. It's been working out great. Getting a nice nostalgia experience. Playing emulators full screen on my TV and whatnot. Now the only thing that irked me about this was that my TV has a resolution limit of 1360x768. Eventually I got used to it. Now a couple of days ago, out of nowhere I decided to look at my display settings, and all of a sudden, my TV's resolution limit was gone. It went all the way up to 2048x1536. I was actually able to change the resolution passed it's original limit and the changes were made on the TV. I was finally able to have both my monitors at a 1920x1080 resolution. I even started using a wallpaper specifically made for two monitors with that resolution. In fact, here's a screenshot I took.

I had to restart my computer and when it finished booting up, the resolution limit was back. And it went from saying "Generic PnP Monitor" (Which is how it was listed before I restarted my computer and before the resolution limit disappeared) to "Sanyo LCD" (Which is the TV brand). I'm curious is to how this is possible. Is there something I may have done to remove this limit? Is there something I can do again to remove it? As far as I'm concerned, I didn't do anything in particular to display settings or anything that may have caused this.
