1
00:00:00,000 --> 00:00:06,480
even if you have the biggest baddest graphics card on the planet your games

2
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

3
00:00:09,240 --> 00:00:14,880
your monitor I'm talking about motion blur that effect you see when the

4
00:00:13,200 --> 00:00:19,260
visuals on your screen get smeared around so things look blurry or ghosted

5
00:00:17,220 --> 00:00:23,039
do note that this is completely unrelated to the motion blur setting you

6
00:00:21,960 --> 00:00:28,859
might find in some of your favorite games which adds an artificial cinematic

7
00:00:26,519 --> 00:00:34,140
blurring effect if you quickly change the camera angle real motion blur has

8
00:00:31,619 --> 00:00:38,160
been the bane of Gamers for a very long time not only does it look unappealing

9
00:00:36,420 --> 00:00:42,899
but in Competitive Gaming it can actually interfere with your performance

10
00:00:40,140 --> 00:00:48,899
but why exactly is motion blur still a problem and how is NVIDIA's new ulmb2

11
00:00:45,540 --> 00:00:50,460
trying to fix it well the main cause has

12
00:00:48,899 --> 00:00:53,460
to do with how most computer monitors are designed you'll often see a

13
00:00:52,020 --> 00:00:58,620
specification when you're monitor shopping called response time and simply

14
00:00:56,460 --> 00:01:03,059
put this is how long it takes the pixels to change colors usually measured as how

15
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

16
00:01:05,640 --> 00:01:12,119
backlight meaning just about anything that isn't an OLED response times are

17
00:01:10,020 --> 00:01:16,500
not instantaneous it actually takes a few milliseconds for your monitor's

18
00:01:13,680 --> 00:01:20,520
pixels to execute a change which is long enough for gamers to perceive motion

19
00:01:18,720 --> 00:01:24,600
blur because they're higher beings they're better than most people on these

20
00:01:22,740 --> 00:01:28,979
displays the main way that you can fight motion blur is by enabling backlight

21
00:01:26,939 --> 00:01:33,360
strobing a feature that turns the backlight off for short periods of time

22
00:01:31,259 --> 00:01:37,799
meaning the screen is dark while the pixels are transitioning reducing the

23
00:01:35,400 --> 00:01:43,140
amount of blur you can perceive back in 2015 NVIDIA came out with their specific

24
00:01:40,079 --> 00:01:45,840
flavor of backlight strobing they called

25
00:01:43,140 --> 00:01:50,820
ulmb unfortunately because of the rather long pixel response times back then the

26
00:01:48,360 --> 00:01:54,780
backlight would have to be off for 75 percent of the time this meant the

27
00:01:52,799 --> 00:01:59,640
picture overall would often end up noticeably dim reducing its appeal

28
00:01:57,540 --> 00:02:04,560
especially for competitive Gamers not to mention ulmb would actually have to slow down

29
00:02:02,399 --> 00:02:08,640
the screen's refresh rate in order to give the pixels enough time to

30
00:02:05,759 --> 00:02:14,459
transition however NVIDIA has recently rolled out an improved version

31
00:02:10,400 --> 00:02:16,379
uncreatively named ulmb2 but how exactly

32
00:02:14,459 --> 00:02:20,099
did they solve the issues that plagued the original we'll tell you right after

33
00:02:18,120 --> 00:02:24,120
we think Volta for sponsoring this video introducing Volta spark the

34
00:02:22,440 --> 00:02:28,680
Revolutionary charging cable with interchangeable magnetic tips enjoy

35
00:02:26,520 --> 00:02:33,900
instant one-touch charging thanks to upgraded n54 neodymium magnets with

36
00:02:31,800 --> 00:02:38,400
versatile reversible magnetic tips you can easily switch between devices

37
00:02:35,459 --> 00:02:43,800
experience super fast 5 amp charging and 480 megabytes per second data transfer

38
00:02:41,160 --> 00:02:47,940
for Apple carplay and Android auto plus their military-grade nylon cable comes

39
00:02:46,019 --> 00:02:53,280
with a lifetime warranty upgrade to Volta spark and transform your charging

40
00:02:50,040 --> 00:02:55,019
experience part of ulmb2's Advantage is

41
00:02:53,280 --> 00:02:58,860
that it doesn't have to lower a panel's refresh rate like its predecessor did

42
00:02:56,819 --> 00:03:03,300
this Improvement actually doesn't even come from NVIDIA at all instead it's

43
00:03:01,560 --> 00:03:07,680
simply due to the fact that generally pixel response times are significantly

44
00:03:05,640 --> 00:03:13,920
shorter today than they were back in 2015. WoW ulmb2 also improves upon basic

45
00:03:11,760 --> 00:03:18,480
backlight strobing by controlling pixels on a more granular level you see when

46
00:03:16,440 --> 00:03:22,920
pixels refresh to put a new image on your screen they're typically refreshed

47
00:03:20,459 --> 00:03:27,360
from the top down so when the backlight flashes some of those pixels will be in

48
00:03:25,440 --> 00:03:32,459
a state of transition leading to a phenomenon called crosstalk meaning part

49
00:03:30,360 --> 00:03:38,159
of the image will likely still have some blurring or ghosting but ulmv2 largely

50
00:03:35,700 --> 00:03:42,299
overcomes crosstalk by overdriving certain pixels with higher voltage

51
00:03:40,140 --> 00:03:47,580
causing them to change State more quickly than others too much overdrive

52
00:03:45,000 --> 00:03:53,220
can lead to undesirable visual artifacts but ulmb2 uses overdrive in a controlled

53
00:03:50,640 --> 00:03:58,080
way to create a sweet spot where the number of pixels mid-transition is at a

54
00:03:55,500 --> 00:04:03,299
minimum when the backlight turns on this not only means less motion blur but also

55
00:04:00,780 --> 00:04:07,200
A Brighter Image than the original ulmb since the backlight is turned on for a

56
00:04:05,280 --> 00:04:12,540
greater proportion of the time okay but what's the catch well you'll need a

57
00:04:09,659 --> 00:04:17,400
monitor that specifically supports ulmb2 at the time of writing there are only

58
00:04:14,640 --> 00:04:21,840
two monitors on the market that do and they're not exactly cheap as their High

59
00:04:19,440 --> 00:04:26,040
refresh rate g-sync displays aimed more at the competitive and Enthusiast crowd

60
00:04:23,820 --> 00:04:30,060
the good news nothing's stopping you from just gaming on 150 display if you

61
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

62
00:04:31,740 --> 00:04:37,560
the dating apps anyway and thanks for not ghosting me in watching this whole
