ASUS ZenBook 3 UX390UA is an unique and ultimate ultrabook from ASUS. Everything about this thinnest and lightest ultrabook is a awesome. Whether its design or specifications, its connectivity or its quad speakers, everything is a pro for this slim and stylish laptop.

In this general review, we are going to talk about two ASUS ZenBook 3 UX390UA variants, ASUS ZenBook 3 UX390UA-DH51-GR and ASUS ZenBook 3 UX390UA-XH74-BL. Both models have same design and same features but differ in few specs like processor, RAM, storage and Operating system. So, first we talk about their common specs and features and later we move on to the specs which differ.

Like we said, everything about this model is unique. This is one of the thinnest model at the time of writing this review, which is only 11.9 mm thin and weighs only 910 g. And don't get wrong about performance because of its lightweight weight and thickness, it features the best performing specs which we find in high-end Ultrabooks at the time of this review.

This model's body is made of premium, aerospace-grade aluminum metal which is lighter but stronger and durable than most of the standard laptops. You will enjoy full-sized backlit keyboard and large trackpad with finger-print sensor. Within this thin design, you will find an advanced cooling system which is only 3 mm thick. The heat will go out through the hidden vents in the hinge. You will enjoy Hi-Fi audio through this model's four stereo speakers with four-channel amplifiers designed by Harman Kardon. Audio is processed by ASUS SonicMaster Premium technology in this ASUS ZenBook 3 UX390UA model. So, you will have amazing music listening experience through compact Ultrabook. Overall, with gold color ASUS logo and gold lining on the edges, this model looks very stylish and attractive.

This model features 12.5 inch (16:9) LED backlit FHD (1920 x 1080) 60Hz IPS display with 178 degree viewing angles. And the best part is that this display panel is made up of Corning Gorilla Glass 4.

Getting a Full HD display and with other amazing specs is acceptable for this model. And with that Full HD display, you will enjoy even more brighter and well balanced contrast while viewing images due to ASUS Splendid Technology and have best video watching experience because of ASUS Tru2Life Technology. Overall, this Ultrabook features an Amazing display.

Coming to its connectivity, this model features a single but advanced port, USB 3.1-Type C(Gen 1) port with Thunderbolt 3 technology. This is an all-in-one port for all your connectivity. This advanced option, also has a downside. This is only port to charge or for connectivity. So, you have to use an additional Dock or Mini Dock to connect to other devices. A mini dock is included with any of these models and it features one HDMI port, one USB port and one multi-format SD card reader.

You will have faster wireless internet connectivity with the help of 802.11 ac WiFi. Overall, advanced connectivity options but it may be difficult to use in few situations. With this port you can also enjoy fast charging.

This is a stylish and amazing laptop but lacks a decent webcam. This model features a VGA camera which is the major con for this model. Even convertible laptops under $600 are featuring an HD webcam at the time of this review. So, if you are buying this model, don't think of making high quality conference or video calls. Just don't use the webcam.

This model can give up to 9 hours of battery life. Battery life may depend on your usage, but in general usage, you can expect around 8 to 9 hours of battery life. Overall, this is an amazing Ultrabook to buy.

The best part of this model is its performance. As we said before, this model is available in two different variants at the time of this review. So, in this review we are going to talk about the performance specs of these two variants, ASUS ZenBook 3 UX390UA-DH51-GR and ASUS ZenBook 3 UX390UA-XH74-BL individually.
