Apple drops new iPad's "4G" label, now called iPad + Cellular

Apple appears to have given in to regulatory pressure after the UK's consumer watchdog, the Advertising Standards Agency (ASA), as well as Australia's counterpart, the Australian Competition and Consumer Commission (ACCC) launched investigations following a wave of complaints from consumers about the advertising of the Cupertino-based firm's new iPad 4G capabilities.

While the ASA's concerns didn't result in legal proceedings, the ACCC filed a lawsuit in the federal court of Melbourne accusing Apple of misleading consumers, for which it sought fines and a possible injunction banning sales in the country.

The two met recently for mediation, with Apple agreeing to further clarify the devices' exact network capabilities in store. At the time they rejected the idea of placing stickers on the product's box or changing the name, but they did offer refunds for any iPad owner that was unhappy with his purchase or felt mislead over the 4G speeds when purchasing the tablet.

In a rather interesting move however, over the course of the weekend Apple has re-labeled the popular tablet to "iPad + Cellular" without releasing any press statement or giving any warning ahead of the changes.

There is no doubt that "cellular" is considerably more legal-friendly than before, especially given the tablet's incompatibility with many 4G networks outside of the US and Canada. It's also likely to go a long way towards appeasing the concerns of consumer groups.

The news will be bittersweet for consumers though, as the iconic iPad retailer has already shipped millions of the new tablets in the disputed markets, no doubt buoyed by its 4G claims with consumers blissfully unaware of the 4G's incompatibility with their domestic mobile infrastructure. This is especially true in the UK, where network operators can't seem to even mention 4G in a sentence without it ending in arguments.

Therefore the real winner here is Apple -- the changes effectively bring an end to further legal proceedings and increased criticism from consumer regulatory groups, although the ACCC has made it clear they will be held to account for past conduct and the trial will continue as planned on June 4.

ASRock's High-End Vision 3D 252B HTPC Review 8

REFRESH RATE HANDLING

One of the issues with the ASRock CoreHT 252B was the fact that the integrated Intel HD Graphics 3000 was unable to refresh the display at 23.976 Hz even when configured manually. AMD GPUs have had a history of being close to the desired refresh rates out of the box, while NVIDIA GPUs end up needing some tweaking. This is further compounded by the fact that different setups behave differently even with the same card. How does the GT 540M  in the Vision 3D 252B fare?

As we have recounted in earlier HTPC reviews, a GPU should ideally be capable of the following refresh rates at the minimum:

1. 23.976 Hz
2. 24 Hz
3. 25 Hz
4. 29.97 Hz
5. 30 Hz
6. 50 Hz
7. 59.94 Hz
8. 60 Hz

Some users demand integral multiples of 23.976 / 24 Hz because they result in a smoother desktop experience, while also making sure that the source and display refresh rates are still matched without repeated or dropped frames. The gallery below shows the refresh rate handling for 24, 25 (x2 = 50 Hz), 29.97 (x2 = 59.94 Hz), 30 (x2 = 60 Hz), 50, 59.94 and 60 Hz settings.

The native 23 Hz setting, unfortunately, resulted in a 23.971 Hz refresh rate.

However, with some custom timing setup, we were able to achieve 23.97634 Hz.

The custom timing feature is usable, but not without its quirks. Adding a custom resolution is straightforward. Setting the vertical parameters to values similar to the ones in the screenshot above achieves desired results, but the 23 Hz resolution gets saved as 24 Hz. The pictures in the gallery below bring out the issue. The first picture shows that the 23 Hz setting gets saved as 24 Hz in the NVIDIA control panel. The second picture shows that the 24 Hz setting is no longer available in the set of native refresh rates. The third picture shows that all the available EDID resolutions are displayed in the monitor properties. The fourth screenshot shows that setting the 23 Hz option in the monitor properties puts the control panel in 24 Hz custom mode (with the screen refreshing at 23.97637 Hz). The fifth screenshot shows the effect of setting the 24 Hz option in the monitor properties. Note that the control panel still shows the custom 24 Hz setting. In the sixth screenshot, we selected the 23 Hz setting of the NVIDIA control panel (under native resolution - the one that we actually intended to replace in the first place) only to get the display refreshing at 23.971 Hz. The final picture shows the NVIDIA control panel set to custom 24 Hz resulting in a display refresh rate closer to the intended 23.976 Hz. We hope NVIDIA fixes this annoying issue in one of the upcoming driver releases.

Audio-Technica ATH-M30

The Audio-Technica ATH-M30 headphones offer good build quality and detailed, natural sound with good bass. They're also very comfortable and a bargain at around $60.

There's no integrated microphone for making cell phone calls; the extra-long cord makes the headphones less suitable for mobile use; don't fold-up like the ATH-M35; and the cord isn't detachable.

While they're not in the same league as the step-up ATH-M50 headphones, the Audio-Technica ATH-M30 set costs a lot less and offers impressive performance and decent build quality for the money.

VIDEO  POSTPROCESSING  IN  'ACTION'

HQV scores are meant to be a quantitative metric, but some of the aspects deserve further coverage. In earlier reviews, we had provided screenshots of the Cheese Slices test in order to show deinterlacing performance, and in the Llano review, we looked at issues with the chroma upsampling algorithm. In this section, we will see how the GT 540M fares.

Cadence Detection:

The GT 540M obtains the maximum possible score for cadence detection in the HQV benchmarks. But, is it really effective in all cases? We took the Spears & Munsil Wedge Pattern clip for a test drive. The same test clip was used in our Discrete HTPC GPU Shootout piece. In the previous test, only the GT 430 was able to perfectly inverse telecine the clip. The GT 540M managed to retain that ability.

However, some of the other cadences (including those for which the HQV clips were processed correctly) were not properly inverse telecined / deinterlaced. The gallery below provides information on the troublesome patterns.

In addition, videos often have overlaid text which might be of a different cadence. The 'shredded text' resulting 

from the video processor being unable to do local cadence decisions often ruins the experience. Some GPUs (like Intel's HD Graphics 3000 in the ASRock CoreHT 252B) take more time to lock onto the cadence compared to others (such as those from AMD). Unfortunately, the GT 540M belongs to the former category. It has problems with both horizontal and vertical scrolling text for more than 5 - 10 frames before locking onto the local cadence.

Deinterlacing:

Instead of the Cheese Slices clip, we have a new deinterlacing testclip (a 480i MPEG-2 stream that we first used in the Zotac ZBOX Nano XS review). As expected, the Vision 3D 252B had no trouble deinterlacing this stream. Further down in this review, we also have rendering benchmarks which show how much the IVTC (inverse telecine / cadence detection / film mode detection) and deinterlacing operations load up the GPU.

We also processed the boat clip from the Spears & Munsil disc, and to tell the truth, there is not really much difference in the quality of deinterlacing that we see between AMD, NVIDIA and Intel. All that matters is whether the GPU is powerful enough to deinterlace content at a given frame rate and resolution, and suffice to say that the GT 540M has no problems even with deinterlacing 1080i60 content (as we will see in a later section).

Chroma Upsampling:

The HQV CUE / ICP testclip was used to check up on the chroma upsampling quality of the drivers. In the gallery below, you will find three screenshots taken in the course of playback (one with PowerDVD, one with ArcSoft TMT and the other madVR set to Softcubic (Softness 70) chroma scaling. Though one can say that the madVR output holds the slight edge, it looks like the algorithm used in the NVIDIA drivers is no slouch

Noise Reduction:

The gallery below presents the noise reduction algorithms in action. Noise reduction strength can be set between 0 and 100, and the gallery below has screenshots for 0, 50 and 100 noise reduction settings for each segment of the clip. The noise reduction algorithms work decently, but the difference is not as stark as, say, what one gets with the AMD GPUs when mosquito noise reduction is enabled.

Contrast Enhancement and Skin Tone Correction:

Simply put, the dynamic contrast enhancement and skin tone correction options in the NVIDIA Control Panel do not work. The gallery below presents the necessary proof.

The color tab in the panel has a contrast setting, but that affects the picture as a whole and doesn't work in the manner that the HQV benchmark guide expects it to. Color enhancement is supposed to take care of skin tone correction, but that was quite ineffective too. We remember seeing the dynamic contrast feature working in a previous driver version, and this just goes to prove that NVIDIA is as guilty of breaking HTPC features in their drivers as AMD is. That said, the driver version v301.24 we tested with is not WHQL certified (I had to move up from v296 because there were some graphics driver stability issues in my setup while testing various HTPC aspects). So, we are willing to cut NVIDIA some slack. However, we hope that NVIDIA is aware of this issue and will take steps to correct it based upon user feedback.

ASRock's High-End Vision 3D 252B HTPC Review 6

HQV 2.0 BENCHMARKING

HTPC enthusiasts are often concerned about the quality of pictures output by the system.  While this is a very subjective metric, we have decided to take as much of an objective approach as possible. Starting with the Core 100 review in 2010, we have been using the HQV 2.0 benchmark for this purpose.

The HQV 2.0 test suite consists of 39 different streams divided into 4 different classes. The playback device is assigned scores for each, depending on how well it plays the stream.  Each test was repeated multiple times to ensure that the correct score was assigned. The scoring details are available in the testing guide on the HQV website.

In the table below, we indicate the maximum score possible for each test, and how much the ASRock Vision 3D 252B was able to get. As mentioned in the previous section, we used NVIDIA Graphics Driver v301.24 for the benchmarking.

HQV 2.0 Benchmark - ASRock Vision 3D 252B

		Driftwood	5	2
		Beach at Dusk	5	2
		White and Black Cats	5	2
	Skin Tone Correction	Skin Tones	10	0
		Total Score	210	176

When compared with the other SFF HTPCs, the score doesn't look out-of-place.

However, we have seen NVIDIA GPUs scoring higher in earlier reviews. This is just an indicator of how new driver releases tend to break existing features. As we will see in the next section, there are a number of knobs in the driver which just don't work at all.
