On most of its systems Apple does not support HDMI output, and in order to use HDMI people have had to use adapters such as Apple's DisplayPort-to-HDMI adapter. For the most part these work fine for sending audio and video information to various devices, but some people have found after upgrading to OS X Lion that their HDMI connections are either not showing video, not playing audio, or both.

Unfortunately the root cause of this problem is not too apparent, as the HDMI behaviors seem to be different for different setups. In some instances it happens intermittently, and in … Read more

Sony is returning to its innovative roots with the introduction of a head-mounted display that simulates a 62.5-foot screen.

The Personal 3D Viewer, or HMZ-T1, is billed by Sony as the "world's first 3D compatible head-mounted display equipped with an HD OLED panel." Capable of screening 2D and 3D content, this headset is reminiscent of Glasstron, a similarly designed Sony headpiece (with LCD screens inside) from 1997.

Miles ahead of the predecessor, the HMZ-T1 could be that wow factor Sony has been trying to hit the market with for years.

The company had trotted out a prototype back in January at CES 2011 but officially announced the product in Tokyo today ahead of IFA. It's set for a November 11 release in Japan with a price tag of 59,800 yen, or $781.

Within the headset are two 0.7-inch OLED displays (720p/2.8 million pixels) that have all the features of an expensive high-resolution panel in a small form factor. Within, the optical lens projects a 45-degree horizontal viewing angle to the user with a "virtual viewing distance up to 65 feet." … Read more

If you want to view your smartphone's content on an HDTV, you can either wait for one that supports wireless display technology, such as WHDI, or get what Kanex started shipping today, an MHL HDMI adapter.

When used with an HDMI cable, you can use the phone with any HDMI-based display. The adapter enables users to view videos, games, photos, and other media from their mobile devices in high definition up to 1080p at 60Hz … Read more

AMD's Fusion series of APU processors first grabbed our attention at the beginning of 2011 for their impressive showing in 11.6-inch ultraportable laptops like the HP Pavilion dm1z, offering great performance and battery life for a good price. The E and C-series APUs representing the entry-level and thin-and-light side of the laptop and desktop universe have been updated, with memory and graphics enhancements and a promised gain in resting battery life.

AMD claims 12 hours of resting battery life on a charge on the C-series APUs, and 10.5 hours on the new E-series. Of course, our battery … Read more

The MacBook Air is Apple's new mainstream MacBook, and though the latest version is undoubtedly the best, there are still aspects of this slim laptop that could do with accessories.

OLED, or Organic Light-Emitting Diode, televisions have been promised for years. With the potential for plasma-beating contrast ratios and LED LCD-beating thinness, many enthusiasts still hope for this "ultimate" technology in meaningful screen sizes.

Now, I've made my views on OLED pretty clear, but what do you all think?

Would you be willing to pay extra if the performance warranted it? What if it's a lot more expensive?

The better current-gen plasma and … Read more

Based on some comments in my recent article on LCD brightness uniformity, it seems fair to do a piece on that big bugaboo of plasma HDTVs: burn-in.

So what is it? Is it something to be concerned about? Can you fix it?

Apple's new OS X 10.7 has a number of enticing features and seems to run well on many systems; however, after about a month of Lion being out in the wild, there are several prominent issues affecting some Mac users running Lion that seem to all revolve around the management or processing of graphics.

The first issues are with MacBook Pro systems (specifically the 2010 models), where it seems a bug results in kernel panics when performing specific video-processing tasks, be it the movement of a window, or the editing and management of a graphics file. The systems … Read more

Nearly every LCD TV on the market has a problem: uniformity. Certain areas of the screen are going to be brighter than other areas. On dark scenes, this can be visible and sometimes distracting.

So what causes it? What can be done? … Read more
