Acer V3-571G: Just How Bad Is the LCD?

We’ve made it a habit of pointing out just how bad a lot of laptop LCDs are, and sadly (but not surprisingly) Acer’s V3 laptop does nothing to buck the trend. We’re not even hoping for something like Apple’s Retina MacBook Pro here; I’d setting for just getting a better resolution than 1366x768 on a 15.6” display, and improved contrast would be icing on the cake. The LG LP156WH4 panel sadly provides neither. First, let’s see the results.

LCD Analysis - Contrast

LCD Analysis - White

LCD Analysis - Black

LCD Analysis - Delta E

LCD Analysis - Color Gamut

You get very poor contrast, poor maximum brightness, and weak colors. Note that we’re reporting color accuracy after calibration—run any of the laptops without using calibration software and hardware and you’ll get a Delta E consistently in the 15-25 range. (That might seem horrible, and it is, but it’s basically the same thing you get with every single tablet right now so keep that in mind.) Viewing angles are also really poor, with massive color shifting when you view the display from above or below.

But Can You Do Anything About It?

With all the bad aspects of the LCD, I got thinking: can you replace the panel with something better? As luck would have it, I have one of my favorite LCDs from the past several years ready for just such a test, the AU Optronics B156HW01v4. This particular panel comes courtesy of LaptopScreen.com, and you can even purchase your own for just $86 right now. (The original LP156WH4 costs $65, if you’re curious—and LaptopScreens has it in glossy and matte variants if you’re interested; the B156HW01 v7 is the glossy equivalent of the v4 as well, if you prefer glossy.)

I have to say, having had two cracked LCDs on laptops during the past five or so years, the improved availability of replacements (at very reasonable prices!) is definitely welcome. Even better news: the B156HW01 fits perfectly into the Acer V3 chassis. You can see the disassembly process in the following gallery—I used an old credit card to help pry the plastic chassis apart.

That’s all great news, but sadly there’s not a happy ending to this particular story. Despite a rather complex disassembly process (and the very real potential to break off some plastic clips), even though everything fits the final result was a failure. The original display is a budget 1366x768 panel, and as best I can tell Acer uses a data cable that doesn’t support higher resolutions properly. With the B156HW01 installed, you can boot up the laptop without trouble and even select the 1920x1080 resolution within Windows, but every other column of pixels ends up being white.

Update: The technical explanation is that, much like single-link DVI vs. dual-link DVI, there are single-channel LVDS cables and dual-channel LVDS cables. Single-channel LVDS can support up to 1366x768 (1280x800), but anything beyond that requires dual-channel LVDS. That means if you get a laptop with a 1600x900 display, you can upgrade to 1080p without needing a different cable, but for laptops like the V3 that ship with a native 1366x768 panel you will likely need a different cable. The single-channel LVDS cables have eight missing (empty) wires for the second data channel, which is why every other column ended up blank. Unfortunately, I haven't had any luck finding a compatible cable for the newly launch V3-571G. If you're feeling really adventurous, you could always try to roll your own.

If you can find an appropriate data/power cable, you should be able to get the 1080p display to work properly, but I have to send this laptop back to Acer so I’m not going to spend any more effort on the attempt. In general, you should be able to replace an LCD in a laptop with any LCD that runs at the same or lower resolution (and has the same form factor—note that there are at least four different form factors/mounting mechanisms just for 15.6” screens), but for higher resolution displays you will need a laptop that is designed to support such displays. If you buy a laptop where the manufacturer supports multiple resolutions (e.g. Dell’s XPS 15z can be configured with either a 1366x768 or a 1920x1080 display), you should be able to make the upgrade as well, but ideally you’d just buy a laptop with a quality display in the first place.

When I see 1920x1200 tablets from ASUS and Acer hitting the market, or ASUS’ 1080p Ultrabooks—not to mention Apple pushing their Retina displays on all of their product lines—I keep thinking, “Maybe we’re finally going to see the end of low resolution displays.” After all, go shopping for a new HDTV and you’ll see that no one even bothers with 720p these days and the only HDTVs that aren’t 1080p (or higher) are on clearance. So why is it that our laptops are still stuck with such a low resolution? If you care about displays, my recommendation is to make sure to let your wallet do the talking, and encourage friends and relatives to do the same. (/rant)

    You should severely downgrade any computer with a shitty glossy screen. It's time to call manufacturers out on this massive regression and fraud.

    Are these the "deep blacks" we're supposed to be getting from a glossy screen?

    Even Acer's own "glamour shot" shows the color being washed out by this asinine surface: http://images.anandtech.com/doci/6066/acer-v3-571g...

    The spec table reads 3.21 lbs (1.46kg). Are you sure that is correct?
  • jurgenvwyk - Wednesday, July 4, 2012 - link

    According to acer.co.uk it's 2.6kg( 5.73lbs)

    Sorry -- I used the last Ultrabook review as the base table and forgot to update the size/weight sections. It's fixed now. :-)

    Who really comes to anandtech to read about budget laptops?
  • zorxd - Wednesday, July 4, 2012 - link

    Nobody. We all come here to read about laptops so expensive that we won't buy them anyway. Oh, but we will have the picture in our bedroom.
  • Fx1 - Wednesday, July 4, 2012 - link

    I buy them.

    Sux to be you

    I've always considered Acer the bottom of the pile. I'd personally not buy an Acer desktop or laptop for myself, or recommend one.

    I haven't really seen anything to change that yet..

    Surprisingly, I have an Acer desktop that is going on 6 years old, and it has been more reliable than any other off the shelf system I have had. The only thing that went wrong in this entire time was that the hard drive went out. Otherwise, no problems at all. Maybe I just got lucky though.

    My $500 Gateway i3 2.13ghz laptop from January 2010 is still going strong. It gets used heavily too.
