BenQ BL2711U

The panel manufacturer AUO, a daughter company of BenQ, has been producing 27-inch and 32-inch panels with 4K (UHD) resolution of 3840 x 2160. The first monitor that used this panel was the ASUS PB279Q, who used the 27-inch variant. BenQ followed right after and released the BL3201PT and BL3201PH, which uses the 32-inch variant. The difference between the monitors is that the Bl3201PT uses an AHVA panel, whereas the BL3201PH uses an IPS panel. The BenQ Bl2711U is the company’s take on the 27-inch UHD variant. Seeing the monitor from the monitor, it looks as you would expect for a “BL” series monitor – minimalistic, professional and clean lines. The controls at the lower right of the monitor’s bezel are touch sensitive and in the center of the bottom bezel you find the “Eye Protect Sensor”, which is an ambient light sensor that automatically adjusts the backlight brightness accordingly. Furthermore, there’s an Eco Sensor here, which is a proximity sensor that allows the monitor to reduce its brightness significantly if nobody is using it.

The monitor has a refresh rate of 60Hz with the maximum resolution of 4K (UHD) over the DisplayPort or HDMI 2.0. The panel technology is AHVA (Advanced Hyper-Viewing Angle), which is very similar to LG’s IPS (In-Plane Switching) panel technology. It has excellent color quality, viewing angles and 10-bit color support. The screen is coated with a very light matte texture. The display offers a 4ms response time and has WLED backlight with enhanced phosphors. This is why it’s able to offer 100% sRGB support, while it’s still classified as standard gamut. The monitor is also flicker-free (PWM-free), as it uses DC rather than PWM to control brightness.

The monitor also has PiP (Picture in Picture) and PbP (Picture by Picture) functionality and a lot of different preset modes, such as “Animation”, “Video Editing”, “Graphic Arts” and different kinds “Low Blue Light” modes. The “Low Blue Light” feature allows the monitor to reduce the blue light output of the monitor, which is important for a good nights sleep. Watching blue light before bed tells your body to be alert and you may experience trouble falling in sleep because of that. The following “Low Blue Light” modes are available:

  • Reading (70 % Blue Light Reduction)
  • Office  (60 % Blue Light Reduction)
  • Web-surfing  (50 % Blue Light Reduction)
  • Multimedia  (30 % Blue Light Reduction)

As far as the stand goes, it’s fully tilt, height, swivel and pivot adjustable. Furthermore, the monitor has support for 100 x 100mm VESA (wall mounting). The ports of the BL2711U include DisplayPort 1.2 and HDMI 2.0 (MHL) and both support 60Hz 4K output. BenQ are known for supporting a variety of different input options and that’s also the case here. The monitor also supports DVI-D and HDMI 1.4. Furthermore, the monitor has 3.5mm headphone jack and 3.5mm line-in and 4 USB3.0 ports (1 upstream). The monitor also has some in-built 3W stereo speakers.

The monitor was released in mid-July 2015 in the UK and USA. The price was £590 incl. VAT in the UK and $700 USD in the US. We have now reviewed this monitor and updated this post with our ratings. We find this great 4K monitor to be the best 4K monitor for the money in 2019.

The BenQ BL2711U is a great an amazing color reproduction for UI design and other color sensitive work. It also works at 4K UHD resolution at 60 frames per second (FPS) through a mini DisplayPort to DisplayPort cable. All in all a great alternative to the discontinued Apple Thunderbolt Display and we believe it’s the best budget 4K UHD monitor for color sensitive work at 27 inches
