I fear that making the sets compatible with most keyboards has backfired. Almost all work but consumers don't like that answer. Maybe it would have been best for makers to stay with proprietary but we know it works?
In other words, the common keyboards do work with sets that have such a feature most of the time. As I didn't find your set, I can't check.
I am thinking about getting myself a Samsung 40ES5600R. Some questions:
1. Can I take any wireless keyboard and mouse (e. g. Logitech, Microsoft) and get it to work with the TV?
2. Can I resize the screen to whatever I want? What about when using the Internet?
3. Does the WiFi dongle use up one USB port?
4. I have a Galaxy Tab 10.1. Can I use it in any way with the TV? As in, render what is on the tab onto the TV screen, while sitting about 12 feet away?
