A:AnswerYes. I don't know if a tv exists that has the technology buult in. You usually need a powered USB port off back of monitor and video port (like hdmi) available on tv. The technology Microsoft uses is miracast or something like that. Best Buy sells the adapter you plug into the tv - usually near the surface. Chrome cast is another implementation of the technology. Apple works uses airplay (on Apple TV device).
A:AnswerIt spins dependent on internal temperature. You can get software similar to Cpuid hw monitor to see the temperature and get an idea when the fan is triggered. If the temp is keeps rising and the fan isn't engaging, you have an issue.
A:AnswerOriginally, I had a monitor plugged into one of the DPI ports. I now have a new monitor and it is plugged into the full size HDMI port. These both worked very well.
A:AnswerThe Nvidia GTX 750 Ti has these Display Connectors: One Dual Link DVI-I, One Dual Link DVI-D, and One mini-HDMI. It does not have a DisplayPort which would support a 4K monitor without question. There's a lot of chatter about whether or not the HDMI that comes on this card will support 60hz or not (hdmi v1.4 or greater) for the 4K monitor, but it's not clear if it does. If 4K is important to you, I'd consider replacing the video card that comes with this PC.
A:AnswerAs the others indicated, it does handle two monitors. I believe that you can actually run three monitors on this card, but I've not tried it. The video card has the following ports: One Dual Link DVI-I, One Dual Link DVI-D, and One mini-HDMI. I use the mini-HDMI (a mini hdmi to hdmi converter cable comes with the pc) and the DVI-D on my two monitors. There is also a DisplayPort and HDMI port on the back panel of the PC, but they're both disabled by default due to the video card being on board.
If you're interested in the video details, you can look up the Nvidia GTX 750 TI card on the Nvidia site at http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-750-ti/specifications
A:AnswerTechnically it will work. But monitors and tvs aren't the same so you may have eye strain and such. Things like text won't look as good as on monitors.
A:AnswerThe CPU in this computer is "locked," so you can't do that. You will have to buy a new CPU, the one that ends in K or "Unlocked" version, such as the i7-6700K, which will cost your about 300 dollars give or take.
