I just asked a computer tech guy I had here today the same question:) He said to purchase a cleaning kit specifically made for LED screens, and to clean it when the monitor is cold (not while it's on), otherwise perhaps it would streak. Hope this helps.
No, it does not have an HDMI hookup. This monitor is VGA only. That being said, you can purchase a converter at an additional cost, but you're better off putting that money into a more capable monitor.
I do not see an HDMI port. As to rotating it to portrait, it does not have any way to support it in that position, unless you are a handy carpenter and can do that on your own. I have no reason to do so. I suppose you know the software commands to rotate it in whatever operating system you are using. It does work well in Windows and Debian Linux, if that is useful. The picture is quite good for a budget monitor.
It's not a computer, but it is a monitor. And it did come with a cable to connect to a pc. I have a MAC, so I bought the adapter. Assembly was very easy. It is my second monitor, and I have no idea how I lived before it!
I would say no. You would need a receive that can hook up to a monitor cable and the fresh rate would be lacking. Don't get me wrong - this is a great screen for general everyday home office use - but it is a no-frills monitor. It does not have HDMI so the only option for input would be a monitor cable.
This is the Video Support for Apple Mac Mini MD387LL/A Desktop:
Thunderbolt digital video output
* Native Mini DisplayPort output
* DVI output using Mini DisplayPort to DVI Adapter (sold separately)
* VGA output using Mini DisplayPort to VGA Adapter (sold separately)
* Dual-link DVI output using Mini DisplayPort to Dual-Link DVI Adapter (sold separately)
You would need to also buy a Mini DisplayPort to VGA Adapter. The monitor comes with a VGA cable. To support the VGA output, you would need to also purchase the Mini DisplayPort to VGA Adapter. Otherwise, the monitor works great.
