Acer will launch a laptop computer with HD-DVD drive later this month, it said Tuesday at the Computex trade show in Taiwan.HD-DVD is one of two new optical-disc formats vying to replace DVD for high-definition content. The discs are the same size as current DVDs but hold several times more information, so they can accommodate the larger high-definition files.The laptop will be a new model in Acer\u2019s high-end Aspire 9800 range and will feature an impressive 20.1-inch liquid crystal display screen. The screen is a monitor-class panel of a type not usually found on laptops, so it delivers an image equivalent to a desktop monitor, said Trisha Pan, a product marketing director at Acer.The downside to using such a large panel is the computer\u2019s overall weight. It\u2019s close to 8 kilograms, which is several times that of a standard laptop. It additionally pushes up the size: The machine measures 48 by 35 by 6 centimeters."It\u2019s definitely not for portable use," said Pan.The computer also features twin 120GB hard-disk drives, NVidia GeForce 7600 graphics, a TV tuner and support for various audio technologies including Dolby Digital Live and DTS Connect.A version of the Aspire 9800 without HD-DVD support has already gone on sale and costs around US$2,700, said Pan. Adding HD-DVD support will increase the price by between $200 and $300, she said.To date, only a handful of laptop makers have announced models with HD-DVD. One of the first was Toshiba, which is a major backer of the format. Its machine went on sale in Japan in May. Fujitsu is planning to begin selling an HD-DVD laptop soon.Acer said its support for the HD-DVD format isn\u2019t exclusive. The company is planning to launch a laptop with a Blu-ray Disc drive but hasn\u2019t yet decided on timing for the machine.-Martyn Williams, IDG News ServiceRelated Stories:\n\nAcer Revs Up Dual-Core Ferrari Laptops\n\nToshiba Claims Highest Density HDD Drive\n\nToshiba Picks HD-DVD for LaptopCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
