nice score with the U2410's ... sadly I did not get free monitors I bought these ones 5~ years ago.. on pretty good sale (don't remember exactly ~$400 for the pair i think at the time).. mine are u2210's (so the 21.5" size).. good monitors, mine are on many hours per day and still great after 5 yrs here, blacklight is good and even ....especially for free you should be quite pleased I'd think.
u2410 are only $150 a piece in good condition on ebay.. so.. it's not like i won a lottery or anything. hahaha , costco rotisserie chicken is still a better deal.
What would be an interesting upgrade i think is using 4k 50 inch tvs for monitors...
But I refuse to buy anything until we get ULMB in tvs..
There is a 4k asus 120hz coming, and that should support ulmb.. but it's going to be... ~$2000 and not very large.. only 27 inch..
27 inch is too small for a main monitor at that price..
