Old one GW2270HM BenQ monitor + laptop monitor hz overclock

[merghani]

Hi. Is there any possible way to get more Hz from my monitor? I'm not afraid of breaking it. I am currently using BenQ GW2270HM, playing on Intel HD Graphics. I usually play games like CS 1.6. I want to possible maximize the comfort of playing. I got 87hz from 60. I don't know if there is any other way to improve that a little bit. I am playing 640x480, so the pixel clock is quite small. Why I can't afford more Hz despite the smaller one pixel clock than 1920x1080@87hz front sync back 24 32 32 3 5 10, fully working and tested. I am also playing on a built-in laptop monitor. Same situation. I got 100hz at 1366x768, but I can't get more than that even resolution like 640x480. I hope u will give me some pieces of advice.
