I am using LG monitor from 5 years, no issues till date. Its an LED monitor with enerrgy star rating. The model is LG FLATRON E2060. Comes with D-Sub, VGA ports as standard. Power consumption is quite less and there is no glaring at all. It can handle full hd videos as well without much issues. Image quality is quite good.
I use almost 18-20 hours a day continuosly and i never felt eye issues due to monitor. Of course, I tweak out even hardware lol. Dell is a good brand, but not sure about their monitors. HP? Not sure, but I hate hp laptops due to over hearting and their glossy screens, its almost like mirror reflecting our own image.
Check the models and get something with energy ratings, depending on where you are living. Here, in India power costs are too high in some place, so for me energy efficient hardware is crucial.
Suggest you to check some benchmarks at tomshardware forum, if you are concerned about technical specs.
