Display Analysis

Lenovo's default panel in the ThinkPad A285 is a 1366x768 TN panel, while a 1920x1080 IPS panel is offered as an upgrade option. I find it hard to believe that anyone really wants the TN, but clearly people are still buying it to save a few dollars, especially when they buy in bulk. Some day laptops that cost this much won’t ship with TN displays, but that day is not today. Luckily the review unit is the IPS panel, which also offers touch.

Unlike most device makers, Lenovo still offers a matte coating on their touch displays, which you can see in the image below.

The matte coating blurs the pixels, making it not quite as crisp as a clear coating, but in the office, matte still has a lot of support. It generally helps with lighting, although a quality anti-reflective coating can help as well.

While not high-DPI by most PC standards, the 12.5-inch panel still offers a respectable 176 pixels per inch. There is always a trade-off between resolution and battery life, although TFTs like LTPS and IGZO can help claw back some of the extra power drain.

To measure the display accuracy and characteristics, we use SpectraCal’s CalMAN software suite, along with an X-Rite i1 DisplayPro colorimeter for brightness and contrast readings, and an X-Rite i1Pro2 spectrophotometer for color accuracy testing.

Brightness and Contrast

Display - Max Brightness

Display - Black Levels

Display - Contrast Ratio

The ThinkPad A285 is rated for 300 nits, and manages to achieve a bit over that at 325. It isn’t the brightest device, but the anti-glare coating should help outdoors. The black levels are quite good though, leading to a decent contrast of almost 1300:1. The brightness also goes down to an impressive 3.4 nits.

Grayscale

Display - Grayscale Accuracy

The laptop has a good average grayscale result, although there are definite issues when looking past the averages. The red drops off quite a bit before 100% white, while the blue is too high, leading to a fairly cool display temperature of 7400. The gamma is also too high for most of the range, but then falls off as the brightness gets close to 100%. It isn’t terrible, but it’s pretty average for an IPS panel and clearly there’s no calibration here.

Gamut

Display - Gamut Accuracy

When looking at the sRGB gamut accuracy, we can see that blue is well beyond the correct amount, which pulls magenta off as well. Red is not quite able to hit 100% sRGB, and green is close but slightly out of line.

Saturation

Display - Saturation Accuracy

Looking at the 4-bit spaced saturation sweep, you can see that there’s a consistent error level which increases linearly to the 100% levels. None of the colors are in their range, although the average error level isn’t too bad since it’s much closer near the black end of the scale.

Gretag Macbeth


SpectraCal CalMAN

Display - GMB Accuracy

The Gretag Macbeth colorchecker tests various colors, and not just the primary and secondary values. It also includes the important skin tones. As you can see in the graph, there is quite a bit of error on some colors, and others are much closer to where they should be.

Relative Result

This image shows the requested color on the bottom, and the relative result on the top that the display output. The result is relative due to errors in your display, but it does make it fairly clear as to the color drawbacks with this display.

Display Conclusion

The TN option would be better for everyone if it was just gone, so lets just pretend it is. The IPS is very much just a middle of the road display. It offers a good choice in resolution, but it’s not a high-DPI panel. The IPS display offers good off-axis viewing and good contrast levels, but it’s not the brightest around. The color accuracy isn’t great, but it isn’t terrible either. If you’re just doing office tasks, then there’s likely no issues here regardless, and offering the matte coating on a touch display is something that most office workers will appreciate.

    I'm just not impressed. I thought an AMD iGPU would be very good and the 4 core/8 threads would be killer. But a Intel i5 with a MX150 is faster, better gaming, and better battery life.

    I was hoping for something from AMD but disappointed once again.

    Agreed. I was really hoping this would be good. A SSD, A series APU, mobile 4G LTE service, all in a compact long battery life device is exactly what I want. But so many compromises, such low performance, for that high of a price? I'll have to pass. I guess the razer stealth will have to be my next laptop instead.

    Lenovo was able to fit a 45 watt dual core I7 and a 100Wh battery in the 12 inch X230, their inability to do that with more modern hardware is stunning.

    This thing is just sad. A laptop with not great components in a not great platform. Lets hope AMD really shake their mobile lineup up. If the idle powerdraw issue as well as the common thermal limitations are resolved, these are single chips that offer more GPU but less CPU, which on mobile could mean decent mobile light gaming.

    As usual Lenovo appears to be being far too conservative on the CPU temperature limit. I get that these are business systems, but even in that workload I notice mine hitting those low clocks after getting warm too.

    I was going to suggest using Intel XTU to up that temperature limit, but...Not Intel. Any way to do that here?

    Lenovo Vantage is... dubious - I'm not a fan of it auto-installing with admin privileges doing goodness-knows what. The worst part is that the lovely useful battery gauge also leaks handles, which means Explorer (and the system) gets slower over time and maybe even crashes. To turn it off: Right click the taskbar, Toolbars, Lenovo Vantage Toolbar.

    It's not the only Lenovo thing to do that - I've been in the forums a number of times.

    That Cinebench multicore result is probably a driver/BIOS issue. I have an Acer Nitro 5 with the same APU and the result is 600+. It also rose by 30-ish points after a BIOS update (which also fixed what was probably a power state bug), and before that the original result was 530 that jumped to 570 after removing a "CPU driver". (530 to 604 just with software updates.)

    And it still leaves thermal headroom unused so it could be even better.

    In UK, A285 is available with Ryzen7 and 16GB RAM. Several months ago there was a version with second - removable battery, but for some reasons they've cut it. AMD should put extra effort with drivers though. And some cheap SSD for that kind of money is not relevant.

    good laptop
  • RoboJ1M - Wednesday, December 19, 2018 - link

    One thing that they don't really point out in this review is this:
    Finding a Raven Ridge APU with two RAM slots and a dual channel controller is HARD!
    You should point this out! All the other Raven Ridge laptops in that list are single channel but not stated in their specs, it's really hard to find this stuff out.
    My wife bought herself an HP Elitebook 745 with raven ridge after we got a guarantee that is dual channel.
    You need dual channel APUs, it's wants all the bandwidth you can find.
    And out had an Ethernet socket, a spring loaded collapsible one.
  • Rookierookie - Wednesday, December 19, 2018 - link

    Basically any Lenovo Ryzen notebook has dual channel options.
