key rollover often referred to as ghosting by the marketing departments of keyboard manufacturers which by the way is an incorrect use of the term ghosting but we'll talk about that in a bit is a measure of how many key presses can be registered simultaneously by a keyboard it's represented using the format of X key rollover where X is the value that represents the number of keys that can be pressed simultaneously the max rollover rating a keyboard can have is n key rollover or NK ro which signifies that every key on the keyboard can be pressed simultaneously and every single one of them will be registered by your computer now let's go back to ghosting for a second it has a few meanings nowadays traditionally and this is the proper definition ghosting refers to an extra third key press being registered on your computer as a result of two completely unrelated keys being pressed simultaneously on your keyboard so you're typing away and you hit a and L at the same time and on your screen Al and I there are some other third letter would pop up this is extremely rare on any type of modern keyboard so when you see anti-ghosting on the packaging for your new keyboard what the manufacturer is often referring to is a very weak three key roll over implementation that sometimes doesn't even cover the whole keyboard and offers only partial coverage on certain keys that users are likely to press together like W a and G for FPS gamers typically this kind of anti ghosting is only seen on inexpensive rubber dome or membrane keyboards a quick side note here though guys is that if you want to test out what value of key roll over your keyboard actually has Microsoft of all people has an awesome tool to do so online there's a link in the video description so be sure to check that out now back to roll over it's not just membrane keyboards with shoddy implementations here even on mechanical keyboards until recently users were often surprised to find that full n key roll over only worked on the dated ps/2 connector with the USB interface only being capable of six key rollover which can register up to six letter keys and four modifiers at the same time which is why when a hardcore mechanical keyboard fans have stuck with ps2 and why some mechanical keyboard manufacturers still include ps2 adapters in the packaging for their keyboards in recent years however new developments have allowed full and key rollover to be functional over USB which is why companies like ducky and Corsair can offer it on their keyboards no matter which plug you're using so the astute among you might be asking yourselves by this point in the video is any key rollover even necessary I mean it's certainly cool you know and for geeks like me you know more technology is more better but outside of some very specific cases like programs that allow you to use your keyboard as a piano probably not in my personal experience including gaming word processing web browsing and hardware testing I've yet to really feel like I needed to press more than 6 letter keys and four modifiers all at the same time but let us know in the comments if you can think of some situations where it would be important to you like that time you wrote a letter with your face speaking of your face do you ever wake up in the morning reach for your razor and this has turned into a rusty dangerous mess but you just shave with it anyway because you don't want to go to the trouble of going to a store finding an employee asking them to unlock the razors which are behind a you know an indestructible sheet of Plexiglas because apparently no one in the adult world we trusted to have access to sharp objects if so really Luke I already gave you some Dollar Shave Club razors and if you happen to not be Luke then never worry about that hassle again by subscribing to today's video sponsored Dollar Shave Club their slogan is simple shave time shave money for only a couple of bucks a month they will send you premium bathroom supplies straight to your door stuff like razors thanks Linus that wasn't obvious by the name dollar shave club right as well as dr.
