Question 1

this is version 2.0 ?

Accepted Answer

1.There are only two (2) different kinds of HDMI cables specified by the Industry: High Speed and Standard. 
If you own an HDMI cable, chances are, it is a High Speed, 18Gb/s cable. These cables have been in production since 2006 with the advent of Blu-ray, and if you have bought an HDMI cable within the last 10 years, it is likely High Speed. 
2.All High speed cables are created equal. A cheap 10 dollar cable will perform equally to a 90 dollar cable bought from Best Buy. As long as the cable is High Speed, it will have no problem supporting 4k@60hz with HDR. 
3.As the title of this post states, there is no such thing as an HDMI 1.4 or 2.0 cable. These are the only related to the physical HDMI ports that you plug the cables into. The max bandwidth supported by HDMI 1.4 is 4k@30hz, however, that has zero bearing on the cable you are using. I'll repeat; this is not a cable standard. 
The fact that HDMI 2.0 cables do not exist does not keep cable manufactures from trying to pull one over on you. If a cable states that it is an HDMI 2.0 cable, it is simply a marketing ploy. DO NOT FALL FOR IT. 
Honestly, this is probably why so many people are misinformed. They think they need a new cable for that brand new TV they just bought, and the first cable they click on says "High Speed HDMI 2.0 Cable". 
If you bought a cable within the last 10 years, it will still work perfectly with your 4k HDR TV. Don't buy into Cable Manufacture's Marketing Schemes or the misinformation being perpetuated on this site.

Accepted Answer

Question 4

Is this the cable I need to connect my laptop to a projector?

Accepted Answer

If both your laptop and projector have an hdmi port, then this is the cable for you. Most laptops nowadays have an hdmi port (but I don't know if your projector has one). This is what a hdmi port looks like, make sure it's on both your laptop and projector: http://icdn6.digitaltrends.com/image/hdmi-port-625x300-c.jpgPS: check the cable length before buying to make sure it fits your needs!Hope this helps!
