元器件交易网讯 5月26日消息，据外媒报道，联想首个4K显示器ThinkVision Pro2840m开始接受订单，但价格较高为799美元。

　　这款28英寸显示器推出时间有所延迟，但现已在联想官网接受预定，预计出货时间将在5周后。这款4K显示屏分辨率为3840X2160，4倍于现有的1080p屏幕及电视。因产品趋于多样化，4K显示屏价格已普遍降至699美元以下，三星、夏普、戴尔都推出了4K显示器。

　　ThinkVision Pro2840m本应4月发售，但联想在4K面板采购方面遇到问题。同时联想也延迟了搭配4K屏幕的IdeaPad Y50及Y40的上市，这两款产品将在七月推出。同样被推迟的还有搭配4K屏幕的ThinkVision 28一体机，该产品基于安卓系统。

　　ThinkVision Pro2840m拥有HDMI，DisplayPort和迷你DisplayPort接口，侧面为扬声器和USB接口等外围设备。联想尚未公布该产品的刷新率。（元器件交易网毛毛  摘译）

　　Lenovo is taking orders for its first 4Kmonitor, the ThinkVision Pro2840m, but it’s pricey at US$799.

　　The 28-inch monitor, which was delayed, isavailable on Lenovo’s website, but it won’t ship for another five weeks.

　　Video with 4K resolution displays images at3840 x 2160 pixels, which is four times that of current 1080p high-definitionmonitors or TV. TVs and cameras with 4K resolution are already available andsome 4K monitors have fallen to $699 as more models hit the market. A few 4Kmonitors are available from Samsung, Sharp and Dell.

　　The ThinkVision Pro2840m was due to ship inApril, but Lenovo had problems acquiring 4K panels. The company delayed addinga 4K screen on its IdeaPad Y50 and Y40 laptops, which will now be available inJuly. Lenovo has also announced an Android-based ThinkVision 28 all-in-one witha 4K display, which has already been delayed.

　　The Pro2840m has HDMI, DisplayPort andmini-DisplayPort connections. It has speakers on the side and USB ports toattach external peripherals. Lenovo did not share information about the refreshrate, which is an important measure in reducing flickering. Some recentlow-cost 4K monitors have shipped with a refresh rate of 30Hz on HDMI ports,which is not considered adequate for high-end gaming.

　　Lenovo’s monitor has a TN (twisted nematic)panel, while many advanced users opt for an IPS (in-plane switching) panel formore vivid images and better viewing angles.
