I always bring my laptop with me whenever we go on a family vacation for two reasons.
First reason is so that my kids can watch Netflix or a DVD movie off my laptop during the night at the hotel, and the second reason is so that I can do some work on it if I ever have a need for it.

I have few laptops at home, including Lenovo ThinkPads, HP ProBook, Gateway, and Asus models. All my laptops EXCEPT Lenovo ThinkPads have HDMI port, which allows me to easily connect to a TV at a hotel to redirect the video and audio from my laptop to the TV.
Lenovo ThinkPads, on the other hand, have what's called "DisplayPort", which looks similar to the HDMI port but it won't fit HDMI cable connector.

I always have a spare HDMI cable in my luggage so that I don't forget to pack it whenever I go on a vacation but it was useless whenever I brought Lenovo ThinkPad.

So I bought this DisplayPort to HDMI cable from Cable Matters to keep it inside my luggage along with my HDMI cable.

This cable is very thick and looks durable. I had it for 4 years now and it still works great. My only minor complain, which is not a deal breaker, is that it's a big difficult and awkward to press the release latch when unplugging it from the DisplayPort. However, it appears that they have corrected this by replacing the release latch with a button style latch.

Finally, I wish I had purchased a DisplayPort to HDMI male to female adapter instead so that it will take less space in my luggage and especially since I always have HDMI cable in my luggage, but overall this cable does what it's intended to and works wonderfully with my Lenovo ThinkPad T420s model.

UPDATE:
I gave Cable Master one more shot and not regret it at all.
My first cable was Gold plated version and it's absolutely crap one. You can read review on it below this post.
In short version - bad picture and no way to get a sound out of computer to TV.
Then I decided to try DisplayPort 1.2 to HDTV Cable Supporting 4K 10 Feet and it works like a charm.
Don't even have to touch GC or audio settings - seconds after it was connected to TV I got clear and sharp picture and sound.
Would love to get 15ft instead of 10 just in a case, but then you click on 15ft version it switched to crappy "Golden Plated" one.
Will keep looking for a longer one.

Pros: works right out of box, clear and sharp picture AND sound. No problems whatsoever.
Cons: None so far.
4 stars only because of first purchase and waste of time.

OLD REVIEW ABOUT Cable Matters® Gold Plated DisplayPort to HDTV Cable 15 Feet - do not buy it!

Got this cable 'cos it was only one on Amazon 15ft long DP to HDMI.
I have 750Ti GC and was hopping to get a Samsung TV as 3rd monitor through DP port to watch movies, netflix etc etc.
Well, it's not worked out this way.
Picture quality not even close to what I did expect, less saturated, less brighter, less everything compare to picture I have when connecting computer to TV directly hdmi-to-hdmi. But the worst part is - this cable DID NOT gave me any audio. At all.
It wasn't recognized by sound panel in Win 7 AND audio in Nvidia control panel.
Spend hour and half with techsupp from both Gygabite and Nvidia, checked every and any settings, run tests and everything was working perfect - as soon as this cable is disconnected.
So be aware - there is a chance you'll get such a crap cable and didn't get ANY promised "...high-definition ... flawless audio..." AT ALL.
Will return it tomorrow.

Pros: NONE. And c'mon, guys! "Golden plated" is sooo 90's. Or somewhere still people who believed in it?:O)
Cons: EVERYTHING. Bad picture, NO audio, crap quality.

I am using a laptop docking station with monitors. I wanted to use a digital connection to both as I don't want to use the VGA connector, the picture quality isn't the same. I found a ton of adapters from DisplayPort to HDMI but they were the same price range as this actual cable, you would also then need a HDMI cable, so why bother. The cable quality itself was very good, sturdy feel but flexible for use. The DisplayPort button didn't flex under pressure when inserting it or removing it.

This monitor has speakers built but I use PC speakers instead. I have a DP++ port so not only does the video signal go through the cable, I found that it also pushes audio as well. Once the cable was connected, my PC recognized that second audio source (monitor) but I didn't. While testing the monitor and trying to watch some video on it, I couldn't get any sound. I didn't realize the audio switched from the internal source to the monitor. It took a while for me to realize this and I was able to change it back. the next time I docked the laptop, it happened again. Only then while trying to switch to the internal source did I find the settings to default it. It now pushes the audio out of the PC audio jack as intended.

I have not tried to reverse the cable to see if a signal can flow from HDMI to DP++. I do know that the specs on some of these cables will state if the signal will flow in a signal and or reverse direction. So don't buy it for HDMI to DP++ unless its been confirmed by somoene who owns it already or its stated in specs.

I was excited to find what I thought was the right product - my PC (video card is the Nvidia GTX680) has an HDMI port and I wanted to use that for my second monitor (Dell UltraSharp U2412M 24" LED LCD Monitor that I just bought here on Amazon) which I *THOUGHT* had HDMI but actually has Display Port but no HDMI. No problem, I thought if I got an adapter for HDMI to Display Port all my problems would be solved. Alas, when the cable arrived and I excitedly connected everything up - no joy. Neither the computer nor the monitor recognized each other - now I know why, but was upset with the cable initially. Apparently I was using this cable BACKWARDS from how it can only be used. I guess I didn't know enough to know that the data only flows in ONE direction with this cable! And I understand it is not the cable's fault but rather the way Display Port works that is the issue. I gave it 5 stars because in reading the reviews I discovered that most people are very happy with the cable but a couple of us got stung by our own ignorance which is NOT the fault of this company. Still, maybe it would have been nice to see a much more prominent announcement of this fact for those of us who don't "already know everything". It clearly states this in the description, but in the midst of a bunch of other text. Maybe a large blinking red warning would have done the trick. HA HA! Ah well, we buy, we learn.

I found out my GTX680 also has a Display Port out so I ordered a new 'normal' Display Port cable and am happy to report that everything works just perfect.

These days there are very few things that I actually go to the store and buy. I mostly order things online. Simply because the price is usually better and its just more convenient. Cables are one of those things I usually go to the store and purchase so that I can physically see the cable that I am ordering. There are just so many manufacturers that produce different types of cables of different qualities and repackage and relabel them for specific retailers. You just never really know the level of quality you are getting from cables you order online. Its on of these hit and miss things. Some cables though. Especially conversion cables of a specific length. You just have to order online, because you will be hard pressed to find them in the stores. My point is that these cable matters cables are quality made for their price point. This is my second time purchasing them and you plug them in and forget about them they work so well. The wire terminals seem to be solid and the connection terminals themselves seem to be well made. I do like that these specific cables are fairly thin and cable matters ever has thinner cables in certain connections, called the Ultra Slim cables. So its nice to know where the brand of cables that I can purchase online with out having to worry about if they are good cables or not. Trying to drudge through the thousands and thousands of different cable brands online and look at reviews is just a head ache. I will still be purchasing my cables in the store for the most part, because cables are one of those things that I usually dont know I need right up until I need it, but when the need arrises for me to order my cables online, Cable Matters will definitely be my go to.
