With all-in-one PCs becoming more popular and more models expected to come out in the second half of this year, the market for 19-24-inch LCD monitors is expected to be undermined, according to market sources.

All-in-one PC prices have been dropping fast. While prices were between US$799-899 when all-in-one PCs first hit the market in 2008, they are now approaching the US$499 level.

With vendors actively developing lower-cost all-in-one PCs, the sources noted that LCD monitors with prices range of US$299-399 are expected to see impact on sales. The 19-24-inch monitor segment is likely to take the strongest impact, the sources added.

Global LCD monitor shipments in 2008 went down 2.1% to 158.63 million units, with 72.7% of the shipments coming from Taiwan makers, according to Digitimes Research.
