Review on Dell S2721QS Ultra Thin DisplayPort Certified Pivot Adjustment, Curved, High Dynamic Range, Tilt Adjustment, HD by Steven Twede

Brand new monitor so no long term reviews. But out of the box I couldn't get 4K resolution, there wasn't even a choice in Windows Settings or in my Nvidia Control Panel. Problem? I used an old HDMI cable (with a mini DP adapter on the graphics card) and the system knew about it, so I couldn't even select a higher resolution. Solution: I installed a pure display port cable. The system recognized it and now allows me to select the highest resolution - 3840x2160. Hooray. The cable is important. Just one more problem: I have 2 monitors, another regular HD monitor. I keep moving windows from one monitor to another and it messes up window sizes and scaling. I guess I'll just have to buy another 4K monitor!
