Review 1 for ThinkVision Pro2840m 28-inch 4Kx2K LED Backlit LCD Monitor with Speaker
High hopes, but disappointed
Date:November 25, 2014
"I purchased this monitor back in Sept. with high hopes based on prior Lenovo experience, and the features advertised. I had to immediately return the unit due to the connectors "shorting out". Support was very helpful and sent me a replacment asap, so no issues there. However, the replacement monitor, while displaying colors very accurately, cannot be calibrated to a "usable" level under windows 7. For example, the "gamma" and "brightness calibrations" in windows force me to the ends of the ranges on the monitor's settings... Scrollbars on browser windows are almost invisible. Once thing I noticed about my replacement monitor is that it is at lower firmware level (LN3.01) then my original... As far as I can determine there is no way for me to update the firmware to a newer level, so I suspect I am stuck with an expensive "early" model. I have a Lenovo LT2452pwc sitting right along side of the pro2840m, attached to the same system, and the old monitor is MUCH better."

Some great features, but TN is mistake
Date:October 20, 2014
"This a good first start for the 4k era. The glassy screen is a huge plus since most manufacturers release with matte screens that are less reflective but sacrifice image quality with the anti glare coatings that are kinda like smearing chunky peanut butter on your beautiful screen. Some other "glossy" screens have a cheaper coating, but this one has a glass screen that is the correct way to do it (much like iMac/Apple TB screens). The main negative here is the TN technology driving the panel. This is an improved TN panel with true 8-bit color, but the viewing angle is not great, with color shift even when sitting centered. I'd personally wait for IPS panels at this resolution to come out before jumping to 4k. Hopefully, Lenovo will update this line with IPS and keep the Glassy and they'll have a real winner on their hands."
