I literally left the LG as is from a calibration standpoint... I don't have a professional calibration machine, nor do I plan to buy one....
Here's the one I bought:
Not sure if I can recommend it refurbished when the new one is on sale for $20 more, and this one came with writing on the display... :/
I got a LG IPS 225 myself, came factory calibrated pretty well. Need to turn on sRGB mode for it to stop blinding me.
