PC Club Enpower ENP660: Back to School

LCD Color Accuracy
Two and half year-old notebook LCD technology fails to impress - nothing really surprising there. Let's take a look at how the LCD performs in regards to color accuracy. As stated, we will be looking at the uncalibrated performance as well as calibrated performance using both Monaco Optix XR Pro and ColorEyes Display Pro.
The uncalibrated results continue to be very poor for all of the laptops. Unfortunately, these results represent what the majority of people will see when they use any of these systems, and even if you're lucky enough to have appropriate calibration tools, video playback will still use the uncalibrated colors. The ENP660 ranks at the bottom of our charts along with the HP dv6500t (which also uses a two and half year-old panel), with an average Delta E of 12.1 prior to calibration.
After calibration with Monaco Optix XR Pro, the situation for the ENP660 improves, but it still ranks as one of the lower end LCDs. What about after we calibrate the display using ColorEyes Display Pro?
ColorEyes Display Pro manages to provide better color accuracy on most laptops and the ENP660 is no exception. The average Delta E is cut in half relative to calibration with Monaco Optix XR Pro, although in terms of ranking it still comes in second to last out of the reviewed notebooks.
As a final look at the ENP660 LCD panel, here's a chart showing calibrated versus uncalibrated Delta E with both Monaco Optix XR Pro and ColorEyes Display Pro. ColorEyes also reports significantly lower Delta E prior to calibration, so it could be simply a matter of differing ways of measuring Delta E. Either way, this AU Optronics panel definitely falls on the low end of the quality spectrum.
One final note concerning LCDs is that Windows Vista continues to be a thorn in our sides when it comes to display calibration. Setting profiles is more involved, the result doesn't always seem to work, and we discovered during this article that installing ColorEyes Display Pro/Monaco Optix XR Pro apparently disables the ability to adjust LCD brightness in Windows Vista. We have not yet been able to determine if the problem is in drivers for the colorimeter, the setting of the color profile, or simply the installation of one of the software packages we use for display testing. Whatever the case, imaging professionals should definitely stick with Windows XP for the time being. ColorEyes is apparently working on a software update that will hopefully address Windows Vista compatibility, and Monaco Optix XR is no longer supported or in development. We are able to get calibration results with either package under Vista, but there are plenty of other issues that still need to be addressed.

Be careful of buying anything from PC club. I took a computer and brand new case in for work and both cases were damaged. They stripped the alumium screws out on my Lian Li case and screwed in steel ones that stripped the holes. The black piano mirror finish on the Antec Solo case was scratched. Spoke to corporate and was told that they are not responsible. The have a poor rating by the BBB as they do not respond to complaints.Dadoftwo - Wednesday, August 15, 2007 - link
In your opinion, what is the best notebook/laptop money can buy, under $1000? Primary purpose would be for my daughter, a soon-to-be freshman in college majoring in accounting.JarredWalton - Thursday, August 16, 2007 - link
Look at some of the Turion X2 offerings. HP has some that come in at under $1000 with quite a few upgrades. The V6000Z for example - get a 1.8GHz CPU, 2GB RAM, and Office Basic 2007 for right around $1000. Dell's Inspiron 1521 is also pretty decent, and you can get a better LCD (say 1440x900 or 1680x1050) with 2GB and spend right around $1000. Basically, laptops don't tend to give companies a lot of ways to differentiate on the low end. Most $1000 or under laptops will end up being relatively similar - you can add memory and get a smaller HDD, or get a nicer LCD but have less RAM, or some other tradeoff.daytex5 - Wednesday, August 15, 2007 - link
Did the reviewer actually TYPE on the keyboard? After purchasing the the ENP660, I was initially impressed with the board's solid feel, but was quickly frustrated that such a broad case would include a compressed keyboard. Many of the right side keys (Backspace, Enter, period, etc.) are half-size or smaller. Even worse, the right-side Shift key is the size of a standard letter key making it difficult to hit. Whoever made the decision to include the ten-key numeric keypad was not keeping the target audience in mind.

I used it quite a bit. It's a personal preference, obviously. The point is, outside of the keyboard there's really nothing else that separates this laptop from other laptops with a similar price and features - except for example the dv6500t is actually $125 cheaper. I like the numeric keypad, and I tend to use the left shift when typing. I was never bothered by the slightly smaller key size or the off-center location of the keys. However, I am sure plenty of people would feel differently.IntelUser2000 - Tuesday, August 14, 2007 - link
It says on Page 13: "At times we even see the CPU exceed its normal 1.80GHz clock speed, and likewise the memory runs a little faster than DDR2-667. However, this only occurs for short periods of time and the system stability was never compromised by the changing frequencies."If you paid attention to the Santa Rosa platform, you'll definitely notice that the increased speed isn't the side effect, but a new feature. Santa Rosa platform has Enhanced Dynamic Acceleration Technology, which allows core speed to go up to one bin when one of the two cores are inactive.
I didn't know it also changed the FSB frequencies though.

The thing is, these are very short changes (like less than .5 seconds), and they occur when the system is only moderately loaded - like playing a WMV9 encoded movie in this case. It could be overclocking for Santa Rosa, but it's not even 1 bin. It's overclocking because the FSB is running at 350 MHz instead of 333 MHz for a brief moment. I realize Santa Rosa allows OC'ing of one bin, but for that I would expect a one bin increase.strikeback03 - Tuesday, August 14, 2007 - link
Have you tested ASTRA32 on any other laptops which definitely have a newer/better panel? Unless HP uses the same OEM as the MSI barebones system, it would seem odd that there is that large a stock of old AU Optronics LCD panels laying around.JarredWalton - Tuesday, August 14, 2007 - link
The most recent LCD manufacturing date that I've seen on a laptop came with the Gateway E-155-C (Jan 2006). However, I wouldn't be surprised if AU Optronics had a bunch of old inventory that they clearanced, which could then be used in laptops to keep prices down.Astra32 reports March 2006 on a Dell 3000WFP and December 2006 on an HP LP3065. It definitely does report more recent dates, then, but is it truly accurate? It might be wrong, but AUO does make a lot of LCDs, and the performance of the MSI/PC Club LCD leaves a lot to be desired. I find it hard to imagine that a more recent LCD would have a black level of nearly 1.0 nits.
AUO also has a list of panels they produce, http://www.auo.com/auoDEV/products.php?sec=noteboo...">found here. The panels used in both the HP and MSI notebooks (and a couple other notebooks) don't show up in that list, though later version are there. At the very least, I thinks it's safe to say that the LCD used is an older model. 30 months old? Maybe not, but then why continue to use a 1280x800 panel on a new laptop if not for price reasons?

I have been looking for this information for a long time. By the way, recommend a laptop that will be very convenient for studying.
