Dell Studio 14z LCD Quality

We ran our standard LCD quality tests using ColorEyes Display Pro to see how well this 14.0" LCD panel performs. Unfortunately, this is another case of LCD brightness improving at the cost of LCD contrast ratios. Also, color gamut, color accuracy, and viewing angles continue to be a sore spot for laptop LCDs. It is our understanding that TN panels use the least power, so until that changes it's unlikely we will see dramatic improvements in these areas. Keep in mind that we are testing the "720p" 1366x768 LCD panel; we cannot provide information on how well the 1600x900 upgraded panel performs, although it's a safe bet that it's not going to be any worse.

The LCD panel comes from Seiko Epson (now owned by Sony), but we weren't able to find any additional details online. Testing shows that it has the worst contrast ratio of the various LCDs we've looked at. Color accuracy is reasonable, as is color gamut, but both of those areas are easily overshadowed by the washed out appearance. It's unfortunate that we continue to see such low quality LCD panels in so many laptops. We know higher contrast options exist, and the first thing that LCD panels need to provide is at least a 500:1 contrast ratio -- the real contrast ratio, not some marketing figure. Only when an LCD can deliver that is it worth looking at ways to improve color accuracy and color gamut.

    Newegg has a notebook for $399 right now. Please explain how you justify twice the price. A slightly faster processor, slightly more battery life. Big whoop.

    It helps to link to what you're talking about, or at least mention the name. Let's assume you're looking at the http://www.newegg.com/Product/Product.aspx?Item=N8...">Acer Aspire AS5517-5671, which currently sells for $400.

    1) 15.6" vs. 14.0"
    2) 6.0 lbs. vs. 4.6 lbs.
    3) AMD Athlon 64 TF-20 (1.6GHz) vs. Core 2 Duo P8600 (2.4GHz)
    4) DDR2 vs. DDR3
    5) 160GB HDD vs. 320GB HDD
    6) "Up to" 2.4 hours vs. 4.5 hours (measured)

    When you combine all of those areas, plus chassis design, the Studio 14z is clearly superior to this particular $400 laptop in every way. Does that mean it's worth the extra money? You'll have to decide that. Keep in mind that the Gateway NV52 (benchmarked in this article) is going to be at least 30% faster CPU than the $400 Acer (2.1GHz vs. 1.6GHz), and the 14z with P8600 is almost twice as fast.

    If all you need is a basic laptop and you want to save money, sure, go for a cheap $400-$500 laptop. Don't expect top performance or battery life, and you won't be disappointed. Unfortunately, don't expect top quality either (but it's possible you'll still get a notebook that doesn't have any issues).

    Also a different GPU, no wireless N, no blue tooth, no esata, no 1600x900 resolution screen.

    My question would be, if all you care about is saving money, why not go with a $150 netbook refurb? It would certainly be lighter and have more battery life. And if you drop it and it breaks you don't have to feel so bad because you can just go out and buy a new one :D

    Thanks for the excellent review, Jarred. I really like how you included the POST times, calling out Dell on glossy finish+screen and LCD quality and also adding FPS bars at the native res. One minor request for future reviews of laptops that are obviously unable to handle top-end games: throw in a Source-based game (or some other older engine) for comparison to show what the cutoff seems to be for what kind of game it actually CAN play well with med/high settings at the native res.

    On the POST issue, I wonder if there's something about the GF9400 that makes it POST slowly. My Gigabyte 9400-based mobo takes around 10s as well. I know it's not a vendor-specific issue since a Dell Mini 9 I've had my hands on did it in probably under 5s and booted to XP desktop in exactly 25s (8B SSD, uninstalled factory bloatware). I wonder if the Zotac and Asus 9400 boards also POST slowly...

    very nice review. the comparison you make to the macbook is well-balanced. and i agree that it is a viable--although more expensive--alternative.

    macs tend to be a good deal shortly after their model refresh (since apple tends to keep prices fixed until the next refresh). my problem with macs is that i don't like os x. basically, i run linux or windows as my main os on a mac. given the hint in a comment that anand might review the new macbook, one thing i'd really like to see on anandtech would be benches and battery performance under operating systems other than os x (yeah, i know linux is gonna suck battery-wise but win 7 might be an interesting option).

    If only it didn't have a glossy screen (or rather had a matte option) I'd be the proud owner of one of these otherwise cool, little laptops....
  • Pirks - Tuesday, October 20, 2009 - link

    You were putting MacBooks there always, in the relative battery life graphs, but now you don't? Did you get enough hate mail from wintrolls or what? Death threats maybe? ;)

    Also, do you intend to do a review of the new $999 MacBook they just released? Mighty sweet machine, could you touch it up and pass your thoughts you know? I'd be VERY interested, thanks!
  • JarredWalton - Tuesday, October 20, 2009 - link

    Honestly, I removed the Mac from the graphs more because I know that the testing wasn't entirely Apples to apples. Different browser and web pages mean the Mac may have gotten a boost. Still, when a MacBook can last 3.1 hours with a 45Wh battery on our heaviest load (downloading files, playing a movie, and surfing the web) while a Windows laptop with similar specs can only get 4.5 hours at idle using a 74Wh battery, it's clear that OS X remains better optimized.
  • DominionSeraph - Wednesday, October 21, 2009 - link

    I can't wrap my head around the MacBook run times under OS X. I mean, it ain't like there are magically more c and p states available under OS X. And in your OS Mobility roundup you ran Vista in Power Saving mode -- I know that on my desktop that locks my X2 5200+ into its lowest p-state. If that's applicable to the AMD laptops, then the differences can't be explained by Microsoft OS idle processes causing blips to full-throttle.

    Could you test the MacBook with a MS OS, locked to the lowest SpeedStep setting using RMClock (or the like)? And then try @ max undervolt whilst still locked at idle?

    If max undervolt while locked to lowest frequency can't match OS X at stock settings, I think my head will explode.
  • JarredWalton - Wednesday, October 21, 2009 - link

    I can ask Anand to give it a shot... I think he's working on some MacBook articles already so it's definitely something to investigate. But don't discount the possibility that Windows (especially Vista) is preventing the CPU (and peripherals) from entering minimum C-states for long periods of time. Windows seems to constantly "ping" HDDs and other devices to make sure they're still around or something. LOL
