(Image credit: B&H / Samsung) If you're craving a big monitor mostly for productivity purposes, this 37-inch monster from Samsung is half off today at B&H , or just $249. That's over $100 less than its lowest-ever price at Amazon and $150 more than its current price at Best Buy, making this this perhaps the best monitor deal so far this year. Check out this deal at B&H Just note this is very much not a gaming monitor, as evidenced by its locked 60 Hz refresh rate and 5 ms response time. You certainly could game on it, but it lacks pretty much every modern gaming screen feature, save for its high resolution. Aside from price, the 37-inch size is this monitor's major selling point, as it's pretty rare, sitting between typical 32-inch screens the truly large 40-42-inch monitors. If you're rocking a 27-inch or 32-inch monitor and looking for a size upgrade without spending a lot, this is a no-brainer so long as there's room for it on your desk.…
