I work on some spreadsheets but mostly spend hours a day editing word processing documents. I have set the word-processor zoom at 67% which (with my setup) gives me 3 pages to view concurrently. That is a big efficiency advantage over my old setup. Simply an excellent investment for me.

I use this monitor for work not gaming and is okay not great. Part of the issue on my end is the resolution isn’t fantastic so you get a very large imagine which isn’t great when you’re working in spreadsheets and websites. One thing I will say though is the value for money is tremendous!

Works well looks good. Should be noted that 75Hz will only work on one of the HDMI ports, and not with the DisplayPort. I'm using it on a Linux distribution and I have been issues with waking from sleep, but I'm going to guess that it's an issue with my OS and drivers, not the display itself.

Pro: good picture quality unless you are using the “eye saver mode” then the screen flickers and black objects smear when scrolling. Con: My computer boots faster than the monitor and it does not have good auto screen detection. If you are working with two computers then get another monitor.

I bought this to replace a 2 monitor configuration. I use this for work, not for gaming so cannot comment on refresh rates. I'm using the default refresh rate for the monitor. Pros: +Wide screen but not very bulky or heavy +Jog button very easy to use; menus easy to navigate +Fairly decent options...

Picture looks OK, but i've spent a couple hours now trying to get the speakers to work, i downloaded new drivers, switched hdmi cords, switched hdmi ports, nothing is working. when i hit the 'test' button in the settings, it thinks it is making a sound...but it is not.......
