Overview

27" monitor with WQHD performance and comfort



The iiyama ProLite B2791QSU-B1 is a 27" LED backlit LCD with WQHD resolution and TN panel, giving you an ultra fast 1ms response time and FreeSync technology for smoother and more tear-free gaming. Offering a native contrast of 1000:1, this high quality monitor provides excellent performance for photography, web design and gaming. The monitor features a height-adjustable stand with swivel function that allows for customised adjustment for optimal comfort. You'll appreciate its wide range of connectivity offering compatibility with most platforms.


AMD FreeSync technology


This monitor is AMD FreeSync certified, for high performance with compatible AMD graphics chipsets. AMD FreeSync technology puts an end to jerky games and ripped images with smooth, artifact-free performance at virtually any frame rate. FreeSync technology, available on select AMD APUs and GPUs, solves communication issues between the processor and monitor, eliminating image tearing and jerking for the smoothest gameplay possible!


Flicker Free and Blue Light


With a WQHD resolution of 2560 x 1440 dots, the ProLite B2791QSU-B1 is ready to display all types of High Definition images. This means that you have a larger visible area (about 77% more) compared to a Full HD monitor with 1920 x 1080 pixel resolution.

You then enjoy an incredible viewing experience with vivid and true colours.


Flicker Free and Blue Light


Flicker Free technology has been designed to improve your viewing experience and protect your eyes. This iiyama monitor offers a flicker free display with a blue light reduction function. Blue light emitted from a screen is the most damaging. So with a reduction in the amount of blue light, your eye strain is significantly reduced!


Superb picture quality


The contrast ratio is the measure of the difference between the deepest black and the brightest white that your monitor can display. The Advanced Contrast Ratio is a feature that automatically adjusts contrast and brightness to ensure perfect display quality when watching movies or playing video games.


Ergonomic design


Optimise your working comfort to keep you productive all day long. Place the screen of this iiyama monitor in the ideal position thanks to its ergonomic design! The 90° swivel function allows you to choose between landscape and portrait mode. This function is particularly appreciated by CAD and DTP users.

The screen is also height adjustable by 130mm to allow you to adopt the most comfortable position possible. The 90° horizontal rotation also enhances multi-display working.

    Broke down after 2 years...

    There is nothing wrong with this screen except that it broke down after 2 years and a few months.
    According to the nearest LDLC shop and an independent repairer, parts are nowhere to be found.
    In desperation, I put a message on the Iiyama website which informs me that the warranty is not for 2 years but for 3 years (I would have appreciated if LDLC had told me this before and triggered the exchange procedure).
    From then on, Iiyama's subcontractor sent a carrier to install one of the same model and take the broken one, after an exchange of a few emails. In the end, all's well that ends well, even if it took more than 3 weeks between the breakdown and its resolution. That's still a bit long...

    Super

    Excellent quality screen, the only complaint is that when it lights up it tends to blind, but this only lasts 5 seconds.
    Very happy with this purchase

    Notice

    For the screen:
    Tilt and height adjustment in all directions: excellent
    Weak speaker
    Ideal size for remote workstation (laptop carryover)

    For the order :
    Clear and explicit website, competitive price, delivery in time for collection in shop
    Response in time to requests on the site (e.g.: size of package to know if it fits in the car).
    Poor reception in shop. I don't understand why, in the event of a malfunction, you can't take the product back to the place where it was delivered (this would be a strong differentiator compared to Amazon). The answer was not very courteous and incoherent: if you wanted to be able to return the product, you had to order it in shop. And when asked how to do this: "you have to send us an email"! What an advantage to do this when there is a site of the quality of LDLC!
    What a difference with brands where you can come to any shop in case of a problem, which for me is a major argument compared to Amazon.
    Overall, great first experience with LDLC. It's a shame that the collection point is not as customer friendly as the site's support and that there is no shared tracking of LDLC purchases.

    Top, bright, mobile and with a resolution that offers a clear display

    Looking for a "reasonable" large screen for home use I opted for this iiyama which offers a USB hub, great screen mobility, top, bottom pivot ... The speakers are a little extra but don't expect great quality. The borderless effect (except at the bottom) adds a nice clean design.

    Bright screen with a resolution that offers a very appreciable sharpness.
    Multiple settings for brightness adjustment and blue light filter.
    Comes with HDMI and DisplayPort cable, USB 3 hub cable

    I was originally looking at the iiyama 27" LED - ProLite XB2783HSU-B3 (cheaper) but switched to this model the same evening to get 2560x1440.
    On the XB2783HSU-B3 version the resolution is only 1920 x 1080 which gives a blurred effect.

    Very good for the price

    I did not see how to activate the blue filter.
    However, I use a preset mode which gives warmer colours.

    It's true that the sound is a bit weak but it doesn't saturate at maximum intensity.

    Functional screen

    It has all the elements one would expect from such a screen after reading the technical description, and is therefore suitable for my needs. I don't give it the maximum score for the sake of measurement, in case the display qualities deteriorate over time.

    Suitable and ideal for office work

    I've tested a lot of screens so far... IPS, TN, from 60 to 244Hz... but for a mainly office use, reading (internet, mails etc) this one is the only one that doesn't tire my eyes ! A very good TN !
