A:AnswerThe computer itself is capable of putting out 4k, I have had it on a 4k tv and it works great. As far as changing the screen out, no. You need an external monitor or tv that is 4k capable. I suppose it's possible but I can't see how it would be worth the investment. Dells higher end models of this laptop have 4k screens already.
A:AnswerFor Windows 8 and Windows 10, the Product Key is "injected" onto the computer motherboard at the factory, and the installation and activation processes refer to the BIOS of the computer to verify authenticity and activate Windows. No Windows Product Key is otherwise provided or needed by the customer.
A:AnswerYes and kind of yes. You can add an external monitor no problem via HDMI; However, streaming from the same laptop with an i5 processor that you are also playing games on (even an HQ) at the same time can be pretty dependent on the workload for the CPU. Depending on the games you want to stream like World of Warcraft or League of Legends (if that's what you prefer) then it should be fine, but some streaming programs can take a toll of stress on the CPU and GPU (this I would say can depend on if you have a capture card or not) but either way it is not what I personally would recommend. The bottom of the line is yes, you can stream and play games at the same time, but you might notice a performance drop or FPS drop while initiating both at the same time. I hope this was of help!
A:AnswerThey already do. On the listing for this PC, there should be two color swatches, one red, one black. The red one will show you the red version of this PC.
