even if you have the biggest baddest graphics card on the planet your games
still might not look as crisp as you'd expect but don't blame your GPU blame
your monitor I'm talking about motion blur that effect you see when the
visuals on your screen get smeared around so things look blurry or ghosted
do note that this is completely unrelated to the motion blur setting you
might find in some of your favorite games which adds an artificial cinematic
blurring effect if you quickly change the camera angle real motion blur has
been the bane of Gamers for a very long time not only does it look unappealing
but in Competitive Gaming it can actually interfere with your performance
but why exactly is motion blur still a problem and how is NVIDIA's new ulmb2
trying to fix it well the main cause has
to do with how most computer monitors are designed you'll often see a
specification when you're monitor shopping called response time and simply
put this is how long it takes the pixels to change colors usually measured as how
long it takes to go from one shade of gray to another on any display with a
backlight meaning just about anything that isn't an OLED response times are
not instantaneous it actually takes a few milliseconds for your monitor's
pixels to execute a change which is long enough for gamers to perceive motion
blur because they're higher beings they're better than most people on these
displays the main way that you can fight motion blur is by enabling backlight
strobing a feature that turns the backlight off for short periods of time
meaning the screen is dark while the pixels are transitioning reducing the
amount of blur you can perceive back in 2015 NVIDIA came out with their specific
flavor of backlight strobing they called
ulmb unfortunately because of the rather long pixel response times back then the
backlight would have to be off for 75 percent of the time this meant the
picture overall would often end up noticeably dim reducing its appeal
especially for competitive Gamers not to mention ulmb would actually have to slow down
the screen's refresh rate in order to give the pixels enough time to
transition however NVIDIA has recently rolled out an improved version
uncreatively named ulmb2 but how exactly
did they solve the issues that plagued the original we'll tell you right after
we think Volta for sponsoring this video introducing Volta spark the
Revolutionary charging cable with interchangeable magnetic tips enjoy
instant one-touch charging thanks to upgraded n54 neodymium magnets with
versatile reversible magnetic tips you can easily switch between devices
experience super fast 5 amp charging and 480 megabytes per second data transfer
for Apple carplay and Android auto plus their military-grade nylon cable comes
with a lifetime warranty upgrade to Volta spark and transform your charging
experience part of ulmb2's Advantage is
that it doesn't have to lower a panel's refresh rate like its predecessor did
this Improvement actually doesn't even come from NVIDIA at all instead it's
simply due to the fact that generally pixel response times are significantly
shorter today than they were back in 2015. WoW ulmb2 also improves upon basic
backlight strobing by controlling pixels on a more granular level you see when
pixels refresh to put a new image on your screen they're typically refreshed
from the top down so when the backlight flashes some of those pixels will be in
a state of transition leading to a phenomenon called crosstalk meaning part
of the image will likely still have some blurring or ghosting but ulmv2 largely
overcomes crosstalk by overdriving certain pixels with higher voltage
causing them to change State more quickly than others too much overdrive
can lead to undesirable visual artifacts but ulmb2 uses overdrive in a controlled
way to create a sweet spot where the number of pixels mid-transition is at a
minimum when the backlight turns on this not only means less motion blur but also
A Brighter Image than the original ulmb since the backlight is turned on for a
greater proportion of the time okay but what's the catch well you'll need a
monitor that specifically supports ulmb2 at the time of writing there are only
two monitors on the market that do and they're not exactly cheap as their High
refresh rate g-sync displays aimed more at the competitive and Enthusiast crowd
the good news nothing's stopping you from just gaming on 150 display if you
don't mind a little bit of ghosting it's not nearly as bad as the kind you get on
the dating apps anyway and thanks for not ghosting me in watching this whole
