even if you have the biggest baddest graphics card on the planet your games

00:00:04.080 --> 00:00:11.400
still might not look as crisp as you'd expect but don't blame your GPU blame

00:00:09.240 --> 00:00:14.880
your monitor I'm talking about motion blur that effect you see when the

00:00:13.200 --> 00:00:19.260
visuals on your screen get smeared around so things look blurry or ghosted

00:00:17.220 --> 00:00:23.039
do note that this is completely unrelated to the motion blur setting you

00:00:21.960 --> 00:00:28.859
might find in some of your favorite games which adds an artificial cinematic

00:00:26.519 --> 00:00:34.140
blurring effect if you quickly change the camera angle real motion blur has

00:00:31.619 --> 00:00:38.160
been the bane of Gamers for a very long time not only does it look unappealing

00:00:36.420 --> 00:00:42.899
but in Competitive Gaming it can actually interfere with your performance

00:00:40.140 --> 00:00:48.899
but why exactly is motion blur still a problem and how is NVIDIA's new ulmb2

00:00:45.540 --> 00:00:50.460
trying to fix it well the main cause has

00:00:48.899 --> 00:00:53.460
to do with how most computer monitors are designed you'll often see a

00:00:52.020 --> 00:00:58.620
specification when you're monitor shopping called response time and simply

00:00:56.460 --> 00:01:03.059
put this is how long it takes the pixels to change colors usually measured as how

00:01:01.199 --> 00:01:07.439
long it takes to go from one shade of gray to another on any display with a

00:01:05.640 --> 00:01:12.119
backlight meaning just about anything that isn't an OLED response times are

00:01:10.020 --> 00:01:16.500
not instantaneous it actually takes a few milliseconds for your monitor's

00:01:13.680 --> 00:01:20.520
pixels to execute a change which is long enough for gamers to perceive motion

00:01:18.720 --> 00:01:24.600
blur because they're higher beings they're better than most people on these

00:01:22.740 --> 00:01:28.979
displays the main way that you can fight motion blur is by enabling backlight

00:01:26.939 --> 00:01:33.360
strobing a feature that turns the backlight off for short periods of time

00:01:31.259 --> 00:01:37.799
meaning the screen is dark while the pixels are transitioning reducing the

00:01:35.400 --> 00:01:43.140
amount of blur you can perceive back in 2015 NVIDIA came out with their specific

00:01:40.079 --> 00:01:45.840
flavor of backlight strobing they called

00:01:43.140 --> 00:01:50.820
ulmb unfortunately because of the rather long pixel response times back then the

00:01:48.360 --> 00:01:54.780
backlight would have to be off for 75 percent of the time this meant the

00:01:52.799 --> 00:01:59.640
picture overall would often end up noticeably dim reducing its appeal

00:01:57.540 --> 00:02:04.560
especially for competitive Gamers not to mention ulmb would actually have to slow down

00:02:02.399 --> 00:02:08.640
the screen's refresh rate in order to give the pixels enough time to

00:02:05.759 --> 00:02:14.459
transition however NVIDIA has recently rolled out an improved version

00:02:10.400 --> 00:02:16.379
uncreatively named ulmb2 but how exactly

00:02:14.459 --> 00:02:20.099
did they solve the issues that plagued the original we'll tell you right after

00:02:18.120 --> 00:02:24.120
we think Volta for sponsoring this video introducing Volta spark the

00:02:22.440 --> 00:02:28.680
Revolutionary charging cable with interchangeable magnetic tips enjoy

00:02:26.520 --> 00:02:33.900
instant one-touch charging thanks to upgraded n54 neodymium magnets with

00:02:31.800 --> 00:02:38.400
versatile reversible magnetic tips you can easily switch between devices

00:02:35.459 --> 00:02:43.800
experience super fast 5 amp charging and 480 megabytes per second data transfer

00:02:41.160 --> 00:02:47.940
for Apple carplay and Android auto plus their military-grade nylon cable comes

00:02:46.019 --> 00:02:53.280
with a lifetime warranty upgrade to Volta spark and transform your charging

00:02:50.040 --> 00:02:55.019
experience part of ulmb2's Advantage is

00:02:53.280 --> 00:02:58.860
that it doesn't have to lower a panel's refresh rate like its predecessor did

00:02:56.819 --> 00:03:03.300
this Improvement actually doesn't even come from NVIDIA at all instead it's

00:03:01.560 --> 00:03:07.680
simply due to the fact that generally pixel response times are significantly

00:03:05.640 --> 00:03:13.920
shorter today than they were back in 2015. WoW ulmb2 also improves upon basic

00:03:11.760 --> 00:03:18.480
backlight strobing by controlling pixels on a more granular level you see when

00:03:16.440 --> 00:03:22.920
pixels refresh to put a new image on your screen they're typically refreshed

00:03:20.459 --> 00:03:27.360
from the top down so when the backlight flashes some of those pixels will be in

00:03:25.440 --> 00:03:32.459
a state of transition leading to a phenomenon called crosstalk meaning part

00:03:30.360 --> 00:03:38.159
of the image will likely still have some blurring or ghosting but ulmv2 largely

00:03:35.700 --> 00:03:42.299
overcomes crosstalk by overdriving certain pixels with higher voltage

00:03:40.140 --> 00:03:47.580
causing them to change State more quickly than others too much overdrive

00:03:45.000 --> 00:03:53.220
can lead to undesirable visual artifacts but ulmb2 uses overdrive in a controlled

00:03:50.640 --> 00:03:58.080
way to create a sweet spot where the number of pixels mid-transition is at a

00:03:55.500 --> 00:04:03.299
minimum when the backlight turns on this not only means less motion blur but also

00:04:00.780 --> 00:04:07.200
A Brighter Image than the original ulmb since the backlight is turned on for a

00:04:05.280 --> 00:04:12.540
greater proportion of the time okay but what's the catch well you'll need a

00:04:09.659 --> 00:04:17.400
monitor that specifically supports ulmb2 at the time of writing there are only

00:04:14.640 --> 00:04:21.840
two monitors on the market that do and they're not exactly cheap as their High

00:04:19.440 --> 00:04:26.040
refresh rate g-sync displays aimed more at the competitive and Enthusiast crowd

00:04:23.820 --> 00:04:30.060
the good news nothing's stopping you from just gaming on 150 display if you

00:04:28.680 --> 00:04:33.780
don't mind a little bit of ghosting it's not nearly as bad as the kind you get on

00:04:31.740 --> 00:04:37.560
the dating apps anyway and thanks for not ghosting me in watching this whole
