Display
Lenovo offers two display choices in the X1 Carbon, with a 1920x1080 model as the base option, and a 2560x1440 available with or without touch. While the resolution of the base panel is fine, the fact that it is a TN panel is not, so I would avoid that if at all possible. Thankfully the step up to the higher resolution model for $150 also gets you an IPS panel. With many devices that I see, there are some questionable decisions made, and I think the TN panel on a $1000+ Ultrabook is the one on this device.
Luckily Lenovo shipped the IPS panel for review. It is a 14-inch panel with a full RGB stripe. In the hardware ID the panel is just labeled as Lenovo, so I can’t say for sure who makes this panel. This model also has the touch digitizer. Despite that, it has almost a matte coating applied to it, or at least the anti-reflective coating is quite effective. This display also came with a built in ICC profile, so it was tested with that ICC being used.
To test the display characteristics, we use SpectraCal's CalMAN 5 suite along with the X-Rite i1Display Pro colorimeter for brightness and contrast readings, and the X-Rite i1Pro spectrophotometer for color accuracy testing.
Brightness and Contrast
At 250 nits, the X1 Carbon does not get as bright as much of the competition. In fact, to do the color calibration steps, we set the display to 200 nits which is 92% in the power settings of this device. However black levels are quite good, so the overall contrast ratio is still a respectable 1100:1.
Grayscale
With an average score under three, the grayscale on the X1 Carbon is quite good. The errors do get a bit higher though as the brightness increases, and 100% white actually has a dE of over 5. Gamma drops down quite a bit at the higher brightness levels, and the overall gamma is just 2.0, and the target is 2.2.
Saturation
Saturation accuracy was decent on this display with an overall error level of 3.5, as an average over all of the readings. It is not the best display, but it is far from the worst. It is really the reds that drift off the most.
GMB
The Gretag Macbeth is the most comprehensive of the tests, and it tests quite a few colors including a lot of the flesh tones. The overall score is once again a good, but not great result, at 3.66.
The overall display is really just average, with no really standout features. The brightness is a bit low, but the contrast is good. Colors are off, but not dramatically. Out of curiosity, I also tested the display without the ICC profile as well, and surprisingly it did not have much of a change in the results. When a generic ICC profile is used, it can’t take into account variability in the individual panels.
Generally ICC profiles are the most help to grayscale, so I ran through our calibration to see how much we could improve the panel.
The grayscale sees a significant improvement, with a dE2000 of just 0.454 and gamma is almost spot on a 2.2. This is what calibration should do, so it was great to see the improvement. Unfortunately this only had a mild effect on the color related scores. Without a 3D LUT, there is only so much you can do.
One other thing that I need to mention about the display is that, at least on the sample I received, there was a bit of a twinkle in the display, which was more noticeable on light colors like white. All displays have a bit of this due to the glue and coatings applied, but on the X1 Carbon it was a bit more noticeable than I was used to.
So overall the display is just OK. Back in 2013 when the X1 Carbon first launched, a display of this quality would have been quite welcomed, but as with all things, progress moves forward and expectations get higher with the competition.

Beware the so-called extended warranty(tl;dr -- warranted computer, gone for over 6 weeks so far, dismissive and poor service, want replacement if they can't repair)
I own an X1 carbon (2 years old) which over the last year has started to spike in temperature. The fan software no longer works, so I've installed TPFancontrol and Speedfan (one the first time I reformatted and reinstalled Widows, the other the second time) to manually control the fans. I updated BIOS and drivers, reinstalled Windows, etc. I did the normal blowing out of the vent and so on, but the computer would go up to 90+ degrees Celsius and crash. The wireless stopped working as well--intermittently and irrespective of location/modem/time of day.
I sent the computer in for repair, under my 3 year warranty. The first "repair" did nothing. Within 15 minutes, the computer reached 92 degrees Celsius and crashed 3 times. I sent it back for further repair. (By the way, they didn't return it with all parts of the power cord, even though they insisted I send it, and I marked all the parts on the shipping form). Obviously there is no quality control on their so-called repairs.
I have now been without a functioning computer for over 6 weeks. Lenovo doesn't have the correct parts and cannot find them. Parts for a popular computer that is only 2 years old. Now, as a doctoral student, it's pretty hard to write a dissertation without a computer, but as a consultant, I am losing money, since I cannot consult until I have a computer. Moreover my doctoral program is only funded for so long--every month of waiting equals a month in which I will have to pay out of pocket to be a student. Being without a computer for over 6 weeks has already cost me at least $4000.
But when I contact Lenovo to demand they deal with this issue , they reluctantly promise to add 2 months to my warranty--that's it! An acknowledgement that I've lost 2 months of computer use, and a further tacit acknowledgement that they think it will break again. This is after the problem "escalated." Mind you, they don't actually contact you after you "escalate" even though they insist they will.
Other computer companies will replace a defective computer under warranty if they cannot fix it. This happened with my old Asus, and with my kids' HP also. What is wrong with Lenovo's warranty? I feel that if they cannot fix a 2 year old computer, then this warranty is a fraudulent service they are selling.
And I also feel that anyone considering buying a Lenovo should be aware of how poor their customer service is. They do not call back, though they say they will. They issue "part hold final" emails insinuating that this is the last time they will await a part, but then re-start the part ordering process. They do not know who your case has gone to when it is "escalated" and are entirely confused by their own computer system when you ask about your repair status. The "escalation" people are dismissive and condescending when you do finally get a hold of a person. They do not stand by their product.

I bought this laptop last May after a thorough search. I've been using T410 at work for years, thus the bias. Also I was aware with the quality reduction when Lenovo took over.I chose this laptop for a few reasons
1. Keyboard layout - meaning Enter button and navigation arrows are at the edge; and the trackpad is aligned with the space button.
2. High resolution display available
3. Style/ weight
My experience with it has been quite bad actually.
The WiFi adapter is the worst I've seen. Well, I haven't seen that many, except my old t410 and the usual mix of apple idevices. Eventually I was able to figure out some obscure setting that was disabling the wifi adapter to save power. Still is very slow to connect. With some old router the wifi was not able to identify the encryption method ( in contrast to all other devices ).
As build there are highs and lows. My laptop has a loose screw on the bottom ...
The display is quite annoying. I chose to have touch screen and the look I got is sort of the look that you get when you have a privacy screen on top. Not nice.
The sound from this laptop is absolutely terrible. And this is not about the speakers, is about the sound that comes from the headphones. It makes is pretty much impossible to watch youtube.
There are a few issues with cooling too.
The laptop gets quite hot to hold on lap; let's say that this is expected. However, a second problem is that the air vent is on the right hand side, meaning if I place a mouse there or if I use my right hand for the touch screen I can feel the hot air. My old laptop had it on the left which was much better.

I got a new X1 this week and was disappointed to find the Trackpoint and Keyboard Backlight not working. I called support and upgraded everything, still no go. Lenovo wanted me to send back for repair but I told them I wanted a full refund, and they said OK to that with no fuss. I have an X200 and looking for something faster and with a better display. At this point I will probably buy a used X220.
