Display Quality

While I'm overjoyed to be getting a series of notebooks in featuring panels with decent resolution and quality, I remain at least a little mystified by the IPS panels used in the Mythlogic Callisto 1512 recently reviewed and now the one in HP's Spectre XT TouchSmart. You'll see that while contrast and brightness are both excellent, color gamut is unusually low.

I'll take an IPS panel over a conventional TN panel any day of the week, even if it means sacrificing some of the color gamut, but it's still perplexing as to why that sacrifice is being made in the first place. Gradient testing reveals banding, but not a particularly significant amount and certainly competitive with entry-level desktop e-IPS panels. Subjectively at least, the panel on the Spectre XT is attractive and feels like where I wish notebook panels would start as opposed to being a premium item.

Battery Life

There's more bad news with the HP Spectre XT TouchSmart. HP rates the notebook for up to three hours and 45 minutes of battery life, which is a very unattractive number for a modern notebook with a 48Wh battery. Our testing unfortunately corroborates this; you can run the Spectre XT off the mains, but battery life will underwhelm.

Battery Life 2013 - Medium

Battery Life 2013 - Heavy

Battery Life 2013 - Light Normalized

Battery Life 2013 - Medium Normalized

Battery Life 2013 - Heavy Normalized

Despite the full voltage processor, Mythlogic's Callisto 1512 pulls comparable or better battery life. Part of this certainly owes to the larger battery, but it doesn't really excuse how far behind the Spectre XT's normalized battery life is by comparison. Two hours of battery life in our "heavy" test isn't just bad, it's embarrassing.

Heat and Noise

I've repeatedly cited that one of the benefits of a larger chassis, even if it's still thin, is increased cooling capacity. You can put a full voltage chip in and work the cooling system over, or you can go ULV and benefit from the increased headroom by not having to run the cooling as hard. The HP Spectre XT opts for the latter.

You can see the Spectre XT is clearly tuned for acoustics before thermals. There's a healthy amount of thermal headroom on the Ivy Bridge processor still, but I appreciate how relatively quiet the notebook is even under load.

    Ah, so you can upgrade the hard drive? That would fix one of the gripes at least. If I got it I would swap in my Momentus XT 750 hybrid from my last laptop anyways, not keep the 5400 standard hdd.

    I own this laptop in a European version. It has the i5, instead of i7. I disagree with this review on a couple of points:
    - The unit is very servicable. The underside can be taken off with regular philipshead screws. This gives access to the full system. The harddrive is easily replaced with an ssd, and the caching ssd is a regular mSata ssd. I have replaced both in 5 minutes, one samsung 840 pro 256 and one crucial m4 256. Both were recognized without problems and work great.
    - The memory can also be upgraded by the user very easily, see previous point. The european version came with 4gb, I added 8gb without problems.
    - HP has made it very easy to do a clean install of Windows. If you make a backup tot a usb stick, with the provided HP software, you can then do a clean install. The HP installer will give you the option for a clean Windows install when booting form this usb stick.
    - The glass touchpad functions very well, although you will need to dive into the settings of the touchpad to get it this way.

    What I do agree with this review:
    - The processor speed it throttled for low noise. Mine will even go as far as to get stuck on a low processor speed when the turbo mode is used fo an extended period, this seems to be a bug. Only a restart will fis this.
    - The machine is very quiet, although there are some problems with defective fans. Mine had to go back for a fan replacement, and several forums list users also having this problem.
    - The price is a little hard to justify for the stock version. Compared to other laptop with a 15" full-hd ips touch screen, 3 usb ports and 2.2kg, it is very hard to find a competitor.
    - The built quality is decent. The aluminum looks good, but the softer plastic on the bottom scratches easily. My usb ports have little pieces chipped, as this is one piece of plastic. The bezel around the screen could use some improvement.

    Overall I think your review is a little too harsh if you keep the main competitors in mind. In a perfect world, I would rank this laptop as an 8 (B). Compared to what is actually available on the market, I think it deserves a 8.5 (B+).

    My Dell Studio 15 also does that thing where it gets stuck on low multiplier after a while. I used throttlestop to prevent it, but it is annoying.

    thanks for posting. an honest response from somebody who actually owns it means a lot.

    Well designed high quality chassis and hardware coupled with:

    1. Slow HDD and small SSD cache
    2. Abysmal battery life - its a shame you can call something and "Ultrabook" that barely gets 2 hours of battery life. I get more than this from a 4 year old first gen core laptop with its original battery.
    3. Bloatware city

    HP you just cant help but f'up good things. Cant see who would want this thing.

    Indeed, my 3.5 year old Core 2 Duo laptop on its original 6 cell battery still gets 2.5 hours of moderate use with the screen at half, what the heck HP.

    1080p? Not interested. I'm not buying anything less than 1920x1200. I don't see why 1080 is still being pushed. It's not 2008 anymore.

    1080p needs to die and soon. My Asus Transformer Infinity is 1920x1200 and it's almost a year old now. Why would i buy anything brand new in 2013 which was less?
  • tipoo - Tuesday, May 28, 2013 - link

    16:9 vs 16:10. They aren't directly comparable. And 1920 resolution is still really good for a 15 inch.

    tipoo claims "16:9 vs 16:10. They aren't directly comparable."

    No, pomegranates and shoes aren't directly comparable. Or fish and bicycles. Displays of 16:9 and 16:10 are certainly comparable, and the 16:9's shorter screen always comes out on the losing end of the comparison.

    I agree with you and Trinitron... I'll be keeping my 1920x1200 res monitor as long as I can. I hate that the notebooks (even ThinkPads) went to 1920x1080. at 15" display at 1080 is as TALL as a 14" 1200 display.

    I do understand WHY they do this. Its cheaper to make and its a standard for HDTV and computers. It *IS* super handy to plug your 1080 notebook to a HDTV and not have the notebook flip through video modes and what-not. That is a big plus.

    So... I hope to get a 27" 2500x1440 display in 2 years that costs under $400.
