Hey ive been really unlucky with monitors so far. First I had a VG248QE and that gave me massive headaches and eye strain so i returned that. Then I picked up the BenQ XL2420TE and i still get bad headaches and can notice a difference the instant i turn it on its on factory settings the only thing ive changed is the brightness down to 20. Is there anything i can do to not get these horrible headaches from using it? I don't understand why these monitors are giving me these instant headaches when im use to using TN panels anyway . My current monitor is a discontinued alienware 21.5 inch monitor and have never had a problem with it so im not sure whats going on here any information would help though. thank you for your time and sorry about the typos and formatting.
