Lenovo L27Q QHD Full Monitor Review

Lenovo L27Q QHD Full Monitor Review

With so many developments in screens occurring in recent times, it’s fairly straightforward to miss conventional screens with out the bells and whistles. Lenovo just lately despatched me their newest providing, the L27Q-20 (additionally goes by 65D4GCC1US) for a full evaluation. This monitor sports activities a 2560 x 1440 QHD decision, and options an IPS panel designed for colour accuracy. It additionally clocks in with a MSRP beneath $300, so how good is it? Hold studying to seek out out.

The Lenovo L27Q is encased in heavy obligation plastic, made to resemble aluminum. It includes a close to bezel-less show, which seems to be fairly elegant in individual. Resulting from it’s aluminum brushed look, it separates itself from nearly all of shows available on the market which are usually encased in black or grey plastics. It feels premium to the contact, and I don’t have main complaints relating to the supplies used.

The bottom is a two-piece design; the underside disc attaches to a stand that attaches to the monitor itself. The stand doesn’t permit for any swivel and doesn’t have a peak adjustment, nevertheless the monitor could be tilted up and down relying in your viewing peak. At first look the stand seems to be fairly sturdy and strong, nevertheless I did have some points when using the lean perform of the stand. When tilting the monitor upwards, it’s fairly straightforward to have the stand separate itself from the monitor. You need to train care when tilting the monitor upwards. This situation isn’t a standard factor, and I haven’t encountered it in another monitor I’ve ever examined. Hopefully that is an remoted state of affairs and doesn’t have an effect on different L27Q fashions. I want Lenovo included extra performance within the stand whereas making a compromise with glossy seems to be.

The L27Q retains it easy in relation to inputs. There’s a small space that encompasses a single HDMI 1.four, DisplayPort 1.2, headphone jack, and proprietary energy connection. Because the monitor maxes out with a QHD decision at 60hz, there’s no actual want to include a HDMI port on this monitor; it ought to work simply nice with all your present gear. The headphone jack purely features as an audio-out, as there are not any built-in audio system on this monitor. It additionally outputs at a set quantity and can’t be adjusted in any means, so that you undoubtedly need to pair it with an amp answer. It was capable of energy my V-Moda Crossfade Wi-fi headphones at a average quantity, although I wouldn’t advocate utilizing the jack for any headphone that may’t be powered by a recreation controller or smartphone.

Buttons are situated on the entrance of the L27Q, and are organized in a cushty trend. Many screens these days depend on buttons positioned behind the monitor, poorly-implemented capacitive buttons, amongst different preparations. The L27Q retains controls easy, and the buttons are very conscious of the contact. Coupled with the buttons, the OSD performs equally properly. Traversing the menu system is responsive, although not as on the spot as ASUS’ choices, however larger than some manufacturers like BenQ.

The OSD has some limitations relating to configuration. You will have your normal fare corresponding to Brightness, Distinction, and Dynamic Distinction Ratio, nevertheless there are some noticeable omissions, corresponding to Sharpness and Gamma. The excellent news is that the monitor offers an ideal image general, so synthetic tweaking isn’t obligatory, however these adjustment choices are commonplace in most screens.

I put the L27Q via it’s paces after calibration to see how nicely it fared in uniformity exams after calibration. The show was calibrated to approximate 6500Okay shade temperature and a luminance degree of 120 cd/m². From there, I measured 9 areas of the display and calculated the quantity of deviance from the middle of the display, each in luminance and colour temperature. The most important deviance in mild output was measured in the direction of the underside of the display, with a most deviation of round eight% from the middle. When it comes to shade stability, there was a big deviation in the direction of the underside left of the display, the place shade temperature inscreased by over 300 Okay. Keep in mind that uniformity can drastically differ between models, so this can be unique to the assessment pattern that Lenovo despatched me. Take a look at the exams under to see the deviations intimately:

Lenovo’s L27Q is primarily designed in the direction of colour accuracy, because the monitor is outfitted with an IPS panel able to reproducing 99% of the sRGB shade gamut. For these unaware, IPS know-how is steadily utilized in shows to offer larger shade accuracy than cheaper TN panels, sometimes on the expense of response occasions. Whereas the black ranges aren’t nearly as good as a VA panel, they’re nonetheless deep sufficient to be pleasurable for most individuals. Out of the field, the L27Q comes with a set of preset modes together with Textual content, Video, Low Blue Mild,  and Net Pic. Previous to any measurements, my eye gravitated in the direction of the Textual content mode being probably the most correct out of the field.

Default gamma beneath Textual content mode tracked fairly nicely round 2.2, nevertheless the colour temperature was a decrease than our 6500 Okay calibrated goal, defaulting round 6000 Okay. The L27q does embrace primary RGB changes that will let you tailor the colours individually, a standard function out there in most screens. Utilizing these controls, together with some modifications to distinction, I used to be capable of meet the 6500 Okay goal, together with a dim room brightness of 120 cd/m². An fascinating factor to notice is that the L27Q’s backlight is sort of shiny, even when turned all the best way right down to zero. I nonetheless needed to tweak distinction a bit to realize luminance decrease than 140 cd/m². Fortuitously, I used to be capable of meet this goal as nicely. The modifications to RGB worth, together with the Distinction management allowed the L27Q to realize a mean deltaE of 1.7, nicely under the advisable goal of three. Shade accuracy was good general, nevertheless there was a push in reds that tipped max deltaE measurements as excessive as 5. This might not be corrected with simply the OSD controls, and an ICC profile needed to be created to right this challenge. The outcomes after OSD calibration and an ICC profile could be seen under:

After calibration, the L27Q managed a distinction ratio of 872:1, which is decrease than the marketed 1000:1 distinction ratio from Lenovo, however just like different entry degree IPS screens. Whereas it’s suggested to not add any sharpening to stop artifacts, minor sharpening might help when viewing non-native decision content material in some instances. Because the native decision of the L27Q is 1440p, this is able to have been a very good addition for 1080p content material being upscaled by the monitor, when used for multimedia functions. Though, I can perceive the omission, as this monitor is geared in the direction of PC customers, and sharpening may be executed by way of different means.

Measured White Level: 6540 Okay

Obtain Lenovo L27Q ICC Profile

Observe: ICC Profile was calibrated utilizing an i1 Show Professional, together with BasICColor software program. Preliminary measurements have been carried out utilizing Calman 5. The GPU used on this monitor was the NVIDIA GTX 980 Ti, utilizing inventory settings. These settings require a further ICC profile for accuracy. Use these settings at your personal discretion, as they could look totally different in your show.


So, how does it take care of calibration? Fairly good general! Even with out the ICC profile, pores and skin tones appeared pure, shadow element was seen, and vibrant areas nonetheless maintained element and readability. The monitor’s built-in scaler upscaled 1080p content material to full display, and I couldn’t detect a lot softening inside the upscale. One necessary word nevertheless is to make it possible for your supply is about to output RGB (zero~255) full vary values, because it appears to be the monitor’s choice even by way of HDMI. The L27Q doesn’t supply any inner remapping controls like another screens do, so for those who feed a 16~235 sign, you’ll obtain a washed out image and an inflated black degree. I examined some video games utilizing my PlayStation four set to RGB mode, and this allowed the black degree to take care of zero.14 cd/m². Whereas the black degree can’t match main applied sciences similar to the newest OLED HDTVs and excessive finish LED TVs, it’s troublesome to note with full display content material. Will probably be most obvious in a darkish room whereas watching a film with black bars. It’s consistent with most IPS and TN screens on this worth vary, nevertheless.


We’ve seen a development with sure finances IPS panels offering very low enter lag, corresponding to the quickest TN screens. One of many quickest IPS screens we examined, the ASUS MX279H, was championed in our enter lag database for having extraordinarily low enter lag. Naturally, I used to be curious to see if Lenovo might reproduce this low lag with the L27Q. Positive sufficient, they did! With our lag testing gadget, I measured the highest, center, and backside areas of the display for enter lag with a 1080p/60hz sign:

  • Prime: 1.8ms
  • Center: 9.2ms
  • Backside: 16.6ms

Take a look at these numbers, with a 1080p supply no much less! This monitor is likely one of the quickest screens I’ve ever examined, netting a mean enter lag of 9ms. To confirm this, I booted up my trusty copy of Extremely Road Fighter IV on the PlayStation four, and practiced numerous 1-frame hyperlink combos that I’m acquainted with. I wasn’t capable of detect a distinction between this monitor and different low enter lag screens we’ve examined earlier than, which is an effective signal. I additionally put the monitor by means of its paces with Road Fighter V and Tekken 7, coming away with the identical feeling. Nevertheless, these two video games have considerably greater enter lag inside their engine, together with a buffer for inputs, making it troublesome for testing 1-frame discrepancies. Backside line, you should not have any points utilizing this monitor for any strenuous gaming duties relating to latency.



One disadvantage that the majority IPS screens have is their response time, which usually governs the quantity of blur you see throughout quick movement. TN panels have an edge on this regard, nevertheless it’s primarily as a result of how a lot producers can over drive the panel. The over drive on IPS panels is usually lots much less exaggerated. The L27Q has pretty respectable efficiency throughout quick movement on it’s default over drive setting of Regular. I examined with over drive turned off, in addition to the Excessive setting, nevertheless I discovered the Regular setting to have the perfect stability throughout quick movement. Turning it off causes barely extra blur than Regular, whereas setting it to Excessive reveals a blue hue trailing the UFO, a standard prevalence when over drive is pushed in lots of screens.
