having had one for cloise to 6 months now. Yes they do make all tyhe differenc ein the world. and Online ohh yeah.
I was getting close to 6 frames of lag with my Toshiba 1080p high def TV Flatscreen.
now that i have ASUS gaming monitor at 1ms response and 1ms Input Delay time. i Have no lag. and when i play online i feel like i get first hit every match and always get the hit before hand.
on my TV i felt like i was Lagging when i had 120ms connections, this is because your TV can add up to 70MS input dealy as well as your delay from internet connection like 200ms in game connection that will equal: 16 frames of lag.
you can divide your ms by 16.67 on a 60FPS game or video and on a 30FPS display you divide your MS by 33.3
I reccomend getting my ( Click Me
ASUS VS278Q-P 27" Gaming Monitor 1ms/1ms Click Me)
On display LAg .com they describe that there are two different MS things to worrie about, there is Screen Response time which will be displayed in [MS response time] aqnd then there is TV/Monitor [Input Delay] which is also displayed in MS
Acceptable ranges for Gaming Tournaments is
below 8ms Input Delay and
below 5ms Response.
definitely look at Displaylag.com to find one in your specs and price range, and weed out the toasters.
