The number of Hertz is the number of how many images your screen draws in one second. So monitor with a refresh rate of 60Hz will draw 60 images each second on your screen. To most users, this will look fine and enough but actually, if you would place them in front of a 120Hz screen difference will be visible right away.
In most simple words just looking at a screen that has a higher refresh rate will produce a more natural feel of things, although some people would argue that flickering can not be seen on 60Hz monitors and that should be enough, I would argue that they never watched the movie, played the game or used high refresh rate screen when they can state something like that.
Yes, 60Hz might be enough to look at the web page or read some documents but long exposure to 60Hz can have a tiring effect on the eyes in the long run. 120Hz and above just feel more relaxed and it is far less demanding on the eyes. Watching movies also is much better on a higher refresh screen, with way much less motion blur in fast scenes giving the overall experience a greater natural feel.
Gaming is perhaps an area where a refresh rate of 120Hz and above will show its best. Having a higher refresh rate will be easier on your eyes and can even give you a competitive edge. When for example you have twice more images per second on your screen than your opponent his movement will be more fluid and predictable because of that and overall precision will be much higher when moving the cursor in the game since more frames per second means more precision and smoother movement.
After all the positive things that were said about the advantages of high refresh rates, it is just fair to look at some negatives or in this case only negative one and that is Computer power. As said in the previous section having a 120Hz refresh rate means having 120 frames displayed on the screen per single second. Having even higher monitors like 360Hz means even more frames per second and in order to actually see all of that frames you will need to have enough computer power to back it up. Having for example screen with a refresh rate of 240Hz means nothing if your GPU and rest of the computer are able only to push 150 frames per second, in this case, you will still have 150 frames in one second despite the monitor being able to go to 240.
Generally and with all of my heart I would recommend moving away from 60Hz monitors, yes they are cheaper and more affordable but at the end of the day if you are someone like me who spends most of his daily time in front of the computer you would be grateful to have higher refresh rate screen and save your eyes, and after all, why not enjoy some smoother and better movie and game experience as well as saving your eyesight.

The recently released Windows 10 captivated the mass but its rollout, polished as it might have been, proved everything but seamless. Surf the Internet and you’ll get the gist. People are complaining and they need assistance. Assistance with what you might ask? Many have attempted to make an upgrade but failed after encountering various strange combinations of letters and numbers. These are none other than error codes. If you’ve tried and failed, feast your visuals below as you might encounter one of these 5 Windows 10 Upgrade errors.
Encountering error code 0x80073712 in no way implies that you need to throw out your computer system and acquire a new one. Not at all! This error code simply means that a very important file to Windows might have gone missing or corrupted. This file is crucial to Windows update so without obtaining this file, you won’t be able to proceed with the update.
Likely, there are many programs and drivers installed on your computer. They all play a vital role. However, if you’ve received error code 0x800F0923, it might be time to consider or turn your eyes to installed drivers on your system. Why? Error code 0x800F0923 means that there’s a driver or driver on your current Operating System that’s not compatible with Windows 10. There’s clearly a dilemma here.
That’s a pretty odd error but I will say it's slick… That Windows 10 upgrade error is straightforward. Microsoft is just letting you know that they won’t be able to complete the update to Windows 10 and so they are putting your computer back to where it was. How nice of them.
The error messages above are pretty generic and will manifest when the upgrade fails for one reason or the other. To resolve this issue, you’ll most definitely have to decipher what error code was presented. Identifying that will provide a glimpse into exactly what steps you need to take.
I don’t know about you but I strongly believe Microsoft is subtly letting you know that your computer system is old and needs to be thrown out. Also, this update could imply that your PC needs to install important updates to rev you up to the requirements. All relevant updates to your computer must be installed before you can get past this stage.
This Windows 10 upgrade error has been the talk of the Internet. In fact, users of Windows OS have been making it a mockery. Clearly, not many have had success after encountering this error. Obviously, “something happened” but it’s just not easy to decipher what went wrong. Microsoft is still trying to figure it out.
