60hz,120hz or 240hz refresh rate.Does it really matters?

REFRESH RATE

Before starting the main topic let's talk about the Refresh Rate first. So basically, The refresh rate refers to the to the number of frames a television/monitor can display per second. It's generally measured in Hertz, which is a unit of frequency. A Monitor or Tv with a 60Hz refresh rate can display 60 images per second, same goes with 120hz and 240hz respectively. Now lets get back to the main topic.

60hz/120hz/240hz

60hz vs 120hz vs 240hz

So A 60 fps (frames per second) video or game played on a 120Hz TV/Monitor will look no different than on a 60Hz TV/Monitor. In a scenarios like this, the TV/Monitor either adjusts itself to match the refresh rate of the source, which effectively turns it into a 60Hz TV/Monitor, or it simply doubles every frame.If your TV/Monitor is connected to a PC which supports a 120Hz input, then at this time having a 120Hz TV/Monitor can be a strong advantage. Now if you have a 60hz Monitor

and you got Nvidia Gtx 1060 or 1070 or even higher, then there is no use of 60hz monitor because these graphics will produce more than 60fps basically in every games (2018-19). A 60hz monitor can not render more than 60fps i.e because [ 1FPS = 1HZ]. So basically you are just wasting the true output of these cards if you are using 60hz screens. I have already talked about Vsync and G sync in previous blog, these tech can help in stuttering and tearing in games or videos.V sync is mainly helpful when you are getting more fps than your monitors refresh rate, it locks the fps to screens rate.( i.e 60fps to 60hz or 120fps to 120hz) .But if your frame dips below 60fps with vsync on 60hz screen then there will be screen stutter,which is solved with new tech G sync.G sync is mainly helpful when your frames are dipping below 60fps(on 60hz or120hz), with G sync on your screen will not stutter and it will provide smooth gameplay ( i,e because G Sync syncs your monitors refresh rate directly to graphic cards optimum output). For more info about Vsync and Gsync check my previous blog. But after that also fact remains same, you cant enjoy the true power of gtx 1070 or 1080 with 60hz screens.

CONCLUSION

So my ending thoughts about this post are, For most people, a TV/Monitor with a 120hz refresh rate doesn't serve a purpose. There is no difference when compared to a 60Hz model if they are both playing standard content.If you are into PC gaming though, a TV/Monitor that supports a 1080p at 120Hz input is very beneficial, since video games can actually be played at that faster refresh rate. A 120Hz monitor or TV displaying 120 fps content will have much smoother and clearer motion. These higher hz screens mostly effective when you are playing fps (first person shooter) or MOBA (multiplayer online battler arena) games.It will boost your gaming performance as compared to 60hz with 60fps. So if you are a Gamer and have a budget for these screens then 100% i will recommend these screens.

Hope you guys have loved it and stay tuned for my next post, see you later...

What is the Difference between Nvidia G-sync Vs V-sync?

G sync

It mainly allows for a dynamic refresh rate that matches the output from your graphic card. It means suppose your graphic card can produce max 130 fps(frames per second) for a particular game, so the Gsync will synchronize these fps to the refresh rate of your monitor. Mostly Gsync is effective when you go below 60fps,you screen will not stutter. So let me tell you what G sync technically do, It updates the screen exactly when the frame is finished and ready to be up by the graphics card whether that is 55 or 59fps. It removes all the problem associated with vsync matches fps, no lag and no stutter. It gives Incredibly smooth, tear-free gameplay at refresh rates up to 240 Hz. NVIDIA built a special collision avoidance feature to avoid the eventuality of a new frame being ready while a duplicate is being drawn on screen (something that could generate lag and/or stutter) in which case the module anticipates the refresh and waits for the next frame to be completed.Overdriving pixels also becomes tricky in a non-fixed refresh scenario and solutions predicting when the next refresh is going to happen and accordingly adjusting the overdrive value must be implemented and tuned for each panel in order to avoid ghosting. Unique features like HDR, frequency-dependent overdrive, and ultra-low motion blur, And a powerful competitive advantage that has made G sync displays go-to equipment for enthusiast E sport players.

V Sync

So before G sync existed we had two modes V sync off and V sync on. So when we turns it off we gets what's called tearing that is basically saying graphics on your screen might contain part of the last frame and part of current frame. And in worst cases you can get multiple tears across the screen so you're seeing 3 or more separate frames on your screen with objects in different positions.With vsync on you will not see any tearing, but , in order to compensate the screen will simply draw two of the same frames whenever your frame rate dips below your refresh rate of the monitor. So basically V sync on means you have 60 hz display and you will run exactly at 60 fps unless your graphic cards (for ex) dips to 59fps just even once , it will draw 2 frames just for that one frame and that is stutter. The other problem with V sync is the lag (which causes input lag). But G sync solves this problem, i have already told you about G sync.

CONCLUSION

So my ending thoughts are, unless you are a ultra pro gamer, Above 60fps you will not notice any big difference with G sync on or off. G sync only helps when your fps go below 60. You screen will not stutter below 60fps with G sync on, with off it will stutter like hell. So if you have budget totally go for G sync screens otherwise not.
