Review: HP HDX18 notebook
Despite the wide adoption of 16:10, with an increasing amount of people using laptops as entertainment devices and Blu-ray appearing more often every month it makes sense to improve the viewing experience.
With some notebooks touting 18- and 16-inch displays the focus on outputting video to a television is diminished as well-they still can, but an 18-inch, 1920×1080 display is good enough for most people. Click to enlarge HP's HDX18 is their newest entertainment powerhouse.
It, along with the HDX16, is it the company's first 16:9 offering, marking one of the earlier releases in what will be a major trend. The HDX18 is a do-it-all computer that HP is hoping will appeal to people who want to accomplish a lot with one purchase, from a Blu-ray player, to a media PC, to an entertainment hub, to an HD television. It runs Windows Vista Home Premium 32-bit.
Also included is an HDTV tuner, and two remote controls, one which fits the ExpressCard slot for easy storage. This is to say that it's built well enough for home use and light traveling, but it doesn't compare to something like the company's Elitebooks. This approach has generally been more than sufficient for consumers.
The 8.82-pound notebook is on the thin side for what it is, but the 18.4-inch display is going to ensure that it doesn't get moved around much. Above the trackpad is a button that will disable it, in case you want to use your mouse instead.
Above the keyboard is a touch-sensitive panel where users can adjust the volume, use media controls, and toggle WiFi. It uses stylish white LEDs along with blue orange for the WiFi indicator. This panel was actually the part of the HDX18 that gave me the most trouble. The problem was that our test system kept adjusting settings for no reason.
When this happened HP's software would be triggered and it would say that the volume, bass treble, or WiFi status had changed, which would interrupt a movie or gaming session. HP's Assistant software could be removed to stop these pop-ups, but it didn't seem to fix the touch strip. Anyway, WiFi still toggles itself off and then back on occasionally but, from my research, this problem appears to be isolated to our test system.
From a performance standpoint, the HDX18 did quite nicely under most circumstances. The T9600 processor did its job well and combined with 4GB of RAM and 9600M graphics means 1080p playback goes very smoothly. You can upgrade to quad-core, but it's not necessary for the vast majority of users.
Desktop work, even intensive tasks, can be handled with relative ease. This is not a system that you'll want to take on the road much, but it is under the nine pound mark, so it's better than some other "luggable" systems. This is a respectable number for a system this large, but nothing amazing. The use of a 16:9 display along with included Blu-ray makes it a great system for watching television and movies.
Throw in a remote controller, better-than-expected sound, and a setup powerful enough to playback 1080p video and you have yourself a very nice media machine. On-board Firewire, eSATA, and a TV tuner all help complete the experience. I purchased to replace a zd8000. The HDX runs cool - and quiet - the zd8000 had its fans running constantly. The 17-inch screen on the zd8000 is sharper than the 18-inch. But the extra resolution is definitely worth it to me.
Both laptops are about the same weight, but the zd8000 seems more robust. I do not travel much with my laptop, but they do get heavy carting them around airports. My big issue is screen flicker. Occasionally the screen appears to flicker when coming out of sleep mode. This can last a couple of second to 30+ seconds.
I plugged in an external monitor and only the laptop screen flickered. Tech support round 1 went as expected - flash the BIOS and reinstall the video driver. To be expected, but not the solution. A couple more contacts resulted in the ticket being closed.
The "explanation" is that this can occur when the battery is installed and the AC plugged in. The system clickers as it determines which power source to use. I can accept that this explanation is correct. THe laptop screen dims when on battery and the flicker could simply be the screen switching brightness. However, this worries me.
If the problem gets no worse, the I can live with it. But I worry that this is a hardware issue. I am interested in knowing if I am the only one experiencing this problem. I looked at the reviews on the HP site. I also posted a review so I will see it that appears. The screen does dim when you unplug the power cord, but that's because of a setting in Windows power management. Sounds like their may be something wrong with your notebook.

ClearStream2 (C2) UHF Antenna
If you have an HDTV or are thinking about getting one before the analog cutoff early next year, you may also want to consider picking up your digital TV via an antenna. Many of you are concerned that an antenna is an eye sore or that they are just too big to to deal with.
Today we talk about an antenna that takes care of both these issues. According to Antennas Direct, the C2 uses a new breakthrough in size and unmatched ultra efficient design and gain. So in typical HT Guys fashion, we look at this antenna empirically. Tech Specs Range: Up to 50 Miles Gain of 10.2 dBi Consistent gain throughout the entire DTV channel spectrum Dimensions: 20" H x 10" W x 5" D The test site for this review is 45 miles from the LA transmitters and 80 miles from the San Diego Transmitters.
The current setup for OTA is a Winegard HD 9095P. This is a Yagi-style antenna rated for deep fringe. The testing was very straight forward. Put the C2 up against the monster Yagi and see how well it did. It should be noted that Ara lives in a hilly area and that there is a house directly behind and above him.
So this is not a best case scenario to say the least. There were three tests involved. The first was to stick the antenna in a window and scan for digital channels. We weren't expecting much success here but much to our surprise the C2 picked up 9 digital channels. Some of them were channels we actually watch.
The interesting thing was that we picked up two channels from San Diego. Ara has mentioned it in the past but it warrants mentioning again that there are mountains off to the East and the antenna is probably picking up a reflection. The next test was to actually aim the antenna in the direction of the transmitters and hold it outside the window. With this test we were able to pull in 12 channels.
We were hoping for more because at this point it has not been a fair test and the only way to do so was to get up on the roof and put the C2 right next to the Yagi. Anything close to the 45 he currently receives would have kept Ara off the roof. It looks a lot higher when you are up there looking down. For the third and final test we mounted the antenna in the same position as the Yagi and aimed it in the same direction.
The scan was rerun and produced 25 digital channels. The channels that were missing were ones in the higher range. Channels 50 and higher. We could have done better if our topography was less hilly or we had no houses behind us. Even still, the C2 did a great job when you consider its size and our location. Conclusion If you live within 40 miles of the transmitters or you have a clean line of site and live within 50 miles of your transmitters, the C2 antenna is a great way to receive free over the air digital television.
ADSG was the R&D unit of the sound department producing products for movie theaters and movie studios. Two of the products they worked on include the DCP-1000 and DADR-5000. The DCP is a digital cinema processor used in movie theaters around the world. The DADR-5000 is a disk-based audio dubber used on Hollywood sound stages.
ADSG was awarded a Technical Academy Award by the Academy of Motion Picture Arts and Sciences in 2000 for the development of the DADR-5000. Ara holds three patents for his development work in Digital Cinema and Digital Audio Recording. Every week they put together a podcast about High Definition TV and Home Theater.

OPPO DV-983H Upconverting DVD Player - On the Test Bench
This portion of the review details how the OPPO DV-983H performed on the test bench. Please read the OPPO DV-983H Review Essentials, if you have not already.
On the Test Bench The very ability to inspect and view an HDMI video source goes directly against the copyright capability of the connection since the means to see it would infer a means to steal it. At this time the Panasonic PTAE-1000U has been kept in the stable just for the purpose of using the Wave Form Monitor feature.
While the Wave Form Monitor does suffer when looking at high frequency response video such as bursts, it is also the perfect tool for checking IRE levels and color decoding. This does come with the limitation of only being able to check YPbPr output, preventing me from verifiying the switching to RGB output that would be required for a DVI input. Some of the results are based on visual calibration checks as well as signal and are noted.
All tests were performed using Digital Video Essentials as the source material. Comparison Players Toshiba HD-A35 OPPO DV-981HD Digital Video Essentials Video Levels Whether by visual calibration or waveform monitoring, the player output 0IRE and 100IRE at the correct 16 235 levels. Horizontal Frequency Response Luminance As noted, waveform monitoring response was useless for this test.
Visually the player passed the continuous frequency burst test quite well for luminance. For the low frequency pattern there is banding for the highest frequency burst. Moving on to the high frequency pattern, recall that I have yet to see any player or scaler player combo pass this pattern correctly and this player is no exception.
This pattern always has banding so the best I can state on this is high, medium or a low contrast response with high being the best and low being the worst. Vertical Frequency Response Luminance Vertical frequency response was excellent in 720p, 1080i and 1080p. Frequency Response Color While some banding is normal, the DV-983H showed a much higher level of banding than any other player reviewed so far.
The contrast levels also dropped for the right one third of the response, the higher frequencies. The Toshiba HD-A35 remains a reference for this test.
CUE, Chroma Upsampling Error This causes a vertical breakup of color detail in the vertical plane, typically expressed in reds but can show up for other colors, and is related to the player using only one MPEG decoding method rather than both interlace and progressive and applying the correct version to the native source on the disc.
The DV-983H passed. Consider this a mini review. Similar to the HQV Benchmark DVD it, contains similar test material for jaggies, cadence and titles. I tested this disc on the OPPO DV-981HD and the Toshiba HD-A35. The OPPO DV-981HD passed many of the tests but it uses intelligent deinterlacing.
The Toshiba failed horribly and uses dumb deinterlacing which so far infers the disc being played lacks progressive flags, which a dumb deinterlacing design depends upon. The ABT disc image quality and some of the tests like jaggies are better implemented and delivered than the HQV Benchmark.
Scaling I tested the OPPO at 1080p, 1080i and 720p feeding a 1080p DLP front projector that supports 1:1 pixel mapping with other scan rates. As expected the edges were soft which is a byproduct of the scaling process for nearly any manufacturer, although pixel-mapped 1080p output into a native 1080p will provide the sharpest response. Color bar patterns showed the typical dark edging where the different colors meet.
Moving on to test images from DVE at 1080p I was greeted with an overall good response. The unit is not perfect and the DV-981HD and Toshiba HD-A35 have an edge. As noticed for the color burst response test this player is lacking by comparison. Overall either of the other players mentioned faired better with the Toshiba remaining a reference.
This loss of detail was most evident in the restaurant sequence during the table view. The young man has a desert plate with a garnish of cut strawberries. The Toshiba provided better detail and nuance with the DV-983H blurring that. The DV-981HD didn't fair as well but outperformed the DV-983H. The next disc up was Star Wars Episode II, a disc I have tested to no end over the last year with numerous products. As with the above, the response was good but lacked that edge of color detail that the Toshiba can deliver.
I typically don't bring up some DVDs I have burned from a variety of old VCR tapes and laserdisc titles. Eventually one of these will fall into a player and the OPPO was no exception. I bring them up because the OPPO would lose cadence lock if a pause, FF or RW function was used causing a choppy, strobing effect. Going in and out of the modes might get it to lock again.
I have never had this problem with any other player. Scaling Special Features and Oddball Cadences Typically I have two paragraphs describing limitations with such content but it is exactly in this area that the DV-983HD shines. What other players trip up on, this one will pass without a hitch. It passed all but one of the HQV Benchmark cadence tests! If you are a DVD collector looking for the best overall response with ANY content the DV-983HD has you covered.
Just like an external scaler the OPPO delivers the goods yet for detail an external scaler has an edge much like the Toshiba HD-A35. Aspect Ratio Control The DV-983HD provides an auto 16:9 4:3 switching mode so the player maintains correct aspect with special features or 4:3 movies, black side bars. OPPO calls this 16:9 Wide Auto and is found in the setup menu.
For the DVD collector with 4:3 letterboxed content this player performs quite well when expanding such content to fill out your screen. Again the player is directly competing with an external scaler in this capability. Additional Video Features Y C Delay With a calibration disc you test for this error on your display and correct it.
CUE Correction Although the player passes the CUE test there is also ICP, Interlaced Chroma Problem. From the manual, "ICP is caused by encoding interlaced video so you may encounter it on some DVDs". Beyond the specific CUE patterns on the ABT test disc I did not see this feature change anything and it would seem leaving it in automatic will give you the best results.
Video Mode If you are playing back a PAL encoded DVD you can select the front end MPEG video decoder, Video 1, or use Video 2, the Precision Scaling and RightRate video processing technologies of the Anchor Bay processor. This feature was not tested. Color Space Auto is based on information from your display during the HDMI handshake.
Useful if your display EDID is incorrect or missing in action for automated settings. Audio Performance The OPPO provides full bit stream or multichannel PCM support for digital audio connections. Being a simple matter of set-and-forget, there was nothing to test. On the other hand it does provide 8-channel analog audio with 24 192 D A converters and supports SACD and DVD Audio. I tested the PCM stream using a Denon AVR3808Ci A V receiver which provides 24 192 DA conversion for the outputs. In this mode I was able to duplicate all DVD Audio formats out to 24 192.
When an SACD is played the Denon indicates 88.2 kHz. Whether in multichannel or stereo mode SACD lacked in clarity not only from being down converted to 88.2 kHz but also conversion from DSD to PCM. Ultimately, getting the full potential of SACD performance is an audiophile concern and I suggest an audiophile stand alone player.
I know that is not an easy or inexpensive product to find. It is unfortunate but in the end maintaining a pure unconverted signal for SACD from source to decoded analog output, whether that be stereo or multichannel analog or digital, is a huge challenge for the end user on a budget. The player has earned some kudos as an audiophile product so I am going into more depth for this aspect of performance.
Testing of the analog outputs takes us to my 2-channel system which is composed of custom and modified products designed and setup for the ultimate expression of a neutral audio signature.
