big screens high resolution color's so real you'll never want to leave your
room there are plenty of ways that stores will try to sell you a monitor
but there's one key spec that you might not hear much about which is response
time which can make a difference when there's some kind of fast action
happening on the screen oh so you're talking about that thing where there's a
delay between pressing a key and clicking a mouse or whatever and then
having it display on the screen right actually no that's called input lag
which is also important since too much input lag can leave you frustrated at
best or lying in a pool of virtual blood at worst because you couldn't react
quickly enough to an opponent response time however is less about how your
monitor will eventually display inputs from your peripherals after a delay and
more about the individual pixels themselves it's a measure of how quickly
a pixel can display a change from black to white or from one shade of gray to
another different shades of gray represent how intense any given color
will appear on your monitor through a filter the darker the gray the less
light will pass through said color filter and hit your eyes which is why
you don't hear people talking about red to blue response times or anything like
that response times are usually given in milliseconds since one frame on a
standard 60hz monitor stays on your screen for just under 17 milliseconds
the pixels themselves need to transition more quickly than that so they can
display the next frame on time but just because a monitor has a response time
under 17 milliseconds doesn't mean that it's just as good as anything else
longer response times often result in ghosting which means you can see the
remains of trails from a moving object on the screen because pixels took too
long to switch between shades of grey this might not be a huge deal if you
just use your computer as a facebook machine but if you're a gamer or like to
watch movies with fast action poor response times can cause really
distracting visual artifacts so how do you know what's actually good when
looking to buy a monitor checking out their specs and whatnot people have
different opinions on what the maximum response time should be if you're gaming
while some people claim that they can't notice any ghosting on anything below 8
milliseconds there's other people like competitive gamers who swear by super
quick screens with response times of only one or two milliseconds typically
tn panels can be engineered to be quicker than their ips counterparts so
you'll often see higher end tn displays marketed as being for gamers but
remember that you'll also lose color accuracy and viewing angles but hold on
take whatever the manufacturer puts on the spec sheen with a huge grain of salt
there isn't a standardized way for these companies to measure response times so
you might be seeing a cherry picked measurement for how long it takes for a
pixel to switch between two similar shades of grey and end up disappointed
with the actual performance once you hook it up
fortunately this is a situation where a little research can go a long way there
are websites that have independently conducted measurements of response times
as well as input lag times so you can have more apples to apples comparison
when you're shopping and remember to check reviews from a trusted source as
well even if a monitor says that it has lightning quick response time of one to
two milliseconds many people complaining about ghosting could be a clue that
what's on the spec sheet isn't all that accurate so pay attention the next time
you've been marketed for a new display even the biggest highest resolution
screen you can get your paws on will be very disappointing if it makes
everything look like a giant ice cream smear
no it isn't disappointing lynda.com with lynda.com membership you can watch and

thing whatever it happens to be also another right thing to do check out
techwiki i mean general super fun which
is probably on my face now this was techwiki go to the other one that one's
cool that was a little bit more fun and entertaining than techwiki is kind of
like not quite as fun but more educational
i think they like contrast quite well so watching one
after the other and then coming back here might be a good idea if you just bounce back and forth between the two
there you go viewing options anyways don't forget to subscribe bye
