Rated 4 out of 5 by from I like it My old monitor was about 11 years old and of a very low resolution so I needed something new. It had to be relatively small because of the way my desk is set up, and I was having a hard time finding a small monitor that I liked. After shopping around, I found this one and decided to try it. I am glad I did. I used the DisplayPort cable to hook it up, as my graphics card did support that and I understand it is better than HDMI. However, the DisplayPort cable and the power cord included with this monitor were only 5 feet long, which was way too short for the way I have my system set up. The instructions said that the included cables must be used. I contacted customer support and explained my situation and asked them if I could purchase a third party power cord and DisplayPort cable and was told that the original power cord really should be used but was told it was acceptable to use an extension cord. I was told I could use another DisplayPort cable. So I hooked up the monitor with the original power cord using an extension cord and I purchased a 10-foot DisplayPort cable from Walmart which worked out just fine. I turned the system on and found that with the monitor set at the recommended resolution, 3840 x 2160, everything looked very, very tiny, so I kept adjusting the resolution until it was at a comfortable level for me, which turned out to be 1280 x 720. I understand that because of this I am probably not getting the "full benefit" of this ultra-HD monitor. Nevertheless, as I said, that is the resolution that is comfortable for my eyesight, but I did find that the monitor has a very good picture even at this resolution, good colors and good lighting, and I did not even adjust any of the settings, I left the settings at the factory settings. The joystick on/off switch and settings/menu were a little different, but I got used to it quickly. Overall I am pleased that I bought this monitor. I give it 4 stars because of the situation with the cables and the power cord being so short (only 5 feet), which I felt really should have been a little longer. Six feet would have been O.K. in my situation.

Rated 5 out of 5 by from Awesome Monitor This is a great monitor. Moving up to this from a 22" monitor has been great. I do a lot of video editing and motion graphics work that requires lots of tool panels and timelines, etc. all on screen at the same time. This monitor has plenty of space for everything. Setup could not have been easier!

Rated 4 out of 5 by from Would Be 5 Stars But Fonts Too Small Monitor splash screen on start up is ridiculously small ! It is barely readable and I need magnifying glass to read it. Maximum increase font size says 350% which makes it just fine for me but it won't increase anymore in size. Other than that it is a super monitor I use for video editing. I purchased LG 32" monitor but didn't like fuzzy pixels so returned it to Fry's and tried out this smaller size and love the sharpness.
