Market is currently loaded with 4K monitors; you can find several unique designs for beginners as well as professionals.

  • VESA Mount included.
  • Sold Delta E response.


  • It does not offer acceptable luminance uniformity.

Iiyama X4071UHSU 4K Monitor Hardware Design:

1.Design Style

This monitor is designed with a 40 inch screen size that is large enough for general purpose needs but the setup task is quite easier. You simply need to save a 75cm space on desk to place this monitor. On the huge panel size, you will find a small bezel that does not cause any distraction to viewers. As it is installed with fixed feet so you cannot expect screen adjustment options from this monitor. Iiyama X4071UHSU is designed using plastic material; however it is not the best choice but still we can call it reasonable one. Most of users find this monitor like beginner friendly 4K televisions as it does not carry any expensive accent.

This PC monitor works with PWM control on MVA panel so it leads to flicker free performance. Further, the refresh rate is maintained at 60Hz rating but you will not be able to find FreeSync and G-Sync technologies in this monitor. There are five different buttons available on bottom right corner that can help to control on screen display. But you will not find its on screen controls much user friendly as there is no way to adjust gamma curve. Iiyama X4071UHSU takes about 15 seconds to switch on after pressing the power button. The stand for this MVA panel is designed with two bracket type pieces; it is durable enough and can easily extend support to 12Kg screen. However, you will not find it much flexible as it does not allow rotation, pivot adjustment and up/down movements.

2. Ports and Connectivity


Inputs of this monitor are designed to auto with default settings. You can easily access native 4K resolution level with 60Hz refresh rate using DisplayPort and HDMI port. But when used with auto settings then monitor always picks up the HDMI 1.4 and DisplayPort 1.1. It is essential to move to setup section ad make adjustments for Version 1.2 and Version 2.0 respectively. Note that, it is essential to attach AMD graphic cards to ensure perfect content delivery for 60Hz refresh rate at 4K resolution setting.

You will get few necessary cables and one tiny remote control unit with this monitor that helps to manage functions of five different on screen buttons. Although, you need to touch the power button or OSD for few controls but rest settings can be managed from remote itself. On the backside of this panel, you will find 6W speakers that are built inside to deliver classic audio experience. It also stores the power supply inside. The central portion is dedicated for VESA mount with 200x400mm dimension and it can be easily mounted on wall. There is only one HDMI port on right hand portion of the panel that delivers 4K60 content but it is essential to use AMD graphic card to maintain response to desired level. There are two USB 3.0 ports on one side of the panel whereas on other portion, you will find a headphone holder with extendable arm.

Iiyama X4071UHSU 4K Monitor Features and Performance:

1.OSD and Settings

The OSD of Iiyama X4071UHSU can be controlled using buttons that are present on right hand corner on bottom side of this panel. The menu will appear same as predecessors of Iiyama X4071UHSU and it is intuitive enough. You will find Pic in Pic mode the most interesting one but it cannot handle four-way PIP that could otherwise help professionals to handle four inputs at once.

2. Color and Image Quality

When this MVA monitor was tested for contrast level then performance was satisfactory enough with its stunning ratio adjustment at 3,180:1 where black point measurement was somewhere around 0.12. This rating is termed as most impressive one when compared with several wide screen monitors. If we talk about brightness level then results were measured at 385cd/m2 with gamma sitting at 0.1 level. The overall power consumption for Iiyama X4071UHSU is 58W that is observed to be higher than most 32inch IPS models.

Coverage for color accuracy is also quite good where Adobe RGB settles at 87 percent whereas sRGB provides 100 percent accuracy for color gamut. For pre calibrated response, the Delta E value was recorded 2; probably these settings can meet all expectations of professionals from MVA monitors.

Professionals also tested this monitor for gaming performance and it was capable enough to deliver satisfactory results for simple games. But in case if you want to edit word documents on this monitor or wish to browse on web then it appears overpowering. If you wish to mount this large screen monitor on wall then it can deliver incredible results; however, if you are a dedicated desktop user then it is good to search for a smaller screen size, at least something lesser than 32 inch.


Working on 1080p resolution level leads to 24ms input lag on this Iiyama X4071UHSU monitor so we cannot recommend it to high end gamers but it can response better for few simple games like The Witcher 3 etc. The power consumption for calibrated monitor was observed to be 50W for black screen whereas for white screen the power was measured to be 56W that ensures 50% brightness level. Also, it can handle only two inputs at a time with PIP; there is no way to handle four inputs simultaneously so professionals are advised to think about their requirements before making investment.


This 40 inch monitor is well equipped with lots of connectivity options and can deliver stunning 4K content with 60Hz refresh rate. Scaling option also works well with Window 10 and you can have better view for text, icons and other viewing needs. The contrast adjustments are fine with great choice for viewing angles; you will find this monitor good for color specific work performance. Most of the features deliver great performance and the tiny remote appears handy enough. But there are few drawbacks such as input lag issues and improper physical adjustments.
