Is new really better

Mariushm , thank you for comprehensive answer . Yes the other cable is thicker but it appears that it has pins on ports but not wires in cable ,i'll cut open it some other time.Meanwhile , I've ordered another monitor and yet I'm still not satisfied . Perhaps it has something to do with video timings ,so by windows detecting it or graphics software as different monitor it adjusted timings to fit better with that panel .

What hapenned.. So first of all i'm no expert but that does not stop my curiosity i shall first tell u what happened then my observations. Some time ago i (my cat ) broke my TV which i used as computer screen then i replaced it with monitor . That monitor is really old and it takes some time to start up ,like hour or two its different every time but i used it anyways. And since i like to fidget with technology i changed signal cables thinking it starts so slow cause of it . But now with different cable my PC detected monitor as another one. In games visual tearing is almost non existent, i have less of input delay and screen is not getting blurry . Before native resolution was 1680x1050 which i could lower to 1440x900 to put on 75 Hz frequency but now windows does not recommend native one nor i can get it to 75hz . I would like to know whats changed by changing cables . Here's list of hardware used : -graphics card MSI Radeon r9 380 Gaming 4GB -monitor LG Flatron W2234S ( now recognized as ACER S271HL ) - Flatron has d sub input -First cable https://www.ebay.com/itm/Dell-Computer-Cable-AWM-E101344-Style-20276-VW-1-80C-30v-Space-Shuttle-D-/163354638184 -Second cable https://www.ebay.com/itm/VGA-Cable-6ft-Awm-2919-Male-Female-80C-30V-VW1-Low-Voltage-Computer-E300060-/352765825494 - adapter whitch connects those VGA cables to my DVI- i exit on graphics card https://www.amazon.com/StarTech-com-DVI-VGA-Cable-Adapter/dp/B000067SOH Its not placebo effect i'm moba gamer so i notice every tiny detail so please can i get some opinions from experts.
