00:00:00,080 --> 00:00:06,160
if you were shopping for a new monitor a few years ago the general rule was that

2
00:00:03,840 --> 00:00:10,320
gamers would buy tn panels for their higher refresh rates and fast pixel

3
00:00:08,000 --> 00:00:15,120
response times while creative types would get ips type panels for their

4
00:00:12,719 --> 00:00:21,439
accurate colors and wide viewing angles fast forward to today and ips refresh

5
00:00:17,840 --> 00:00:24,880
rates have climbed from 75 to 110 and

6
00:00:21,439 --> 00:00:28,320
even 144 hertz and now

7
00:00:24,880 --> 00:00:31,039
lg is claiming to have also closed the

8
00:00:28,320 --> 00:00:38,719
pixel response time gap with the 27 gl850 a 1440p

9
00:00:34,280 --> 00:00:40,960
144hz ips monitor with an advertised one

10
00:00:38,719 --> 00:00:44,879
millisecond pixel response time by developing a panel with a new

11
00:00:43,040 --> 00:00:49,600
high-speed liquid crystal layer that promises tn levels of speed if they

12
00:00:47,280 --> 00:00:55,610
pulled that off it's an industry first and it's a huge deal but is it marvelous

13
00:00:52,719 --> 00:00:58,780
or is it marketing

14
00:01:01,680 --> 00:01:09,040
the main effect of pixel response time is the motion blur or the trail behind

15
00:01:06,880 --> 00:01:13,680
moving objects and in order to show you guys exactly what the motion blur is

16
00:01:11,040 --> 00:01:18,479
like on this monitor we turned to blurbuster's excellent guide on how to

17
00:01:16,080 --> 00:01:23,439
build your own inexpensive pursuit camera the idea is to put a camera on a

18
00:01:20,880 --> 00:01:27,119
slider and then try to move it at exactly the same speed as the objects on

19
00:01:26,240 --> 00:01:33,439
screen that way you can capture only the aspects of motion blur that are caused

20
00:01:30,960 --> 00:01:37,680
by the display and not those that are caused by the image persistence of the

21
00:01:35,600 --> 00:01:41,360
human eye sliding the camera at the right speed takes a few tries but they

22
00:01:39,680 --> 00:01:46,240
built in this easy way to tell if you did it right if these lines slant

23
00:01:43,759 --> 00:01:50,960
backwards you were too slow forwards means you were too fast and if they

24
00:01:48,399 --> 00:01:53,439
align vertically then you deserve a high 10.

25
00:01:52,479 --> 00:01:56,399
so here's our results

26
00:01:55,520 --> 00:02:01,520
and admittedly the image is still not

27
00:01:59,200 --> 00:02:06,079
crystal clear but maybe we just need some context for this let's compare with

28
00:02:03,680 --> 00:02:11,039
a couple of other monitors then starting with another ultra gear 120hz gaming

29
00:02:08,399 --> 00:02:16,879
monitor from lg that's advertised as having a more typical ips response time

30
00:02:13,599 --> 00:02:18,720
of 5 milliseconds so

31
00:02:16,879 --> 00:02:23,920
there's no real difference in the amount of detail that we can see in our ufo but

32
00:02:22,000 --> 00:02:28,480
where there is a difference is in the amount of ghosting visible on the

33
00:02:26,000 --> 00:02:33,599
trailing edge of the ship as the pixels struggle to switch colors quickly enough

34
00:02:30,720 --> 00:02:40,720
now we also compared the 27 gl850 to a one millisecond tn panel the ASUS pg258q

35
00:02:38,480 --> 00:02:45,040
and again we get a similar level of detail between the two

36
00:02:42,640 --> 00:02:49,920
but interestingly the ASUS has a different visual artifact on the

37
00:02:46,879 --> 00:02:52,319
trailing edge called corona or inverse

38
00:02:49,920 --> 00:02:57,280
ghosting this particular artifact is the result of pixel overdrive a technique

39
00:02:54,959 --> 00:03:02,400
that uses higher voltages to make the pixels switch colors faster now the goal

40
00:02:59,760 --> 00:03:06,800
of overdrive is to reduce ghosting but it often comes with a side effect called

41
00:03:04,879 --> 00:03:11,280
overshoot where the pixel briefly switches beyond the target color and

42
00:03:08,959 --> 00:03:16,640
then has to come back causing this bright inverse ghosting in the 27 gl850

43
00:03:14,959 --> 00:03:20,640
settings which you navigate with the nipple joystick still my favorite for

44
00:03:18,800 --> 00:03:24,159
on-screen displays you can actually adjust how aggressive the pixel

45
00:03:22,400 --> 00:03:28,159
overdrive is the results we've shown you so far were from tests that used the

46
00:03:26,319 --> 00:03:35,120
fast setting when we crank it up to faster we get coronas again just like

47
00:03:31,360 --> 00:03:38,000
the tn and these look really bad in game

48
00:03:35,120 --> 00:03:41,280
like i would never ever put this monitor or for that matter pretty much any

49
00:03:39,680 --> 00:03:47,200
monitor on fastest because it makes it look way

50
00:03:44,480 --> 00:03:52,799
worse with no real benefit that i can see the good news is that to me the next

51
00:03:50,159 --> 00:03:58,159
setting down feels fantastic already like it's really snappy with barely any

52
00:03:56,080 --> 00:04:03,280
overshoot artifacts but that made me wonder why would lg include this faster

53
00:04:00,959 --> 00:04:08,480
setting at all surely they must know as well as i do that it just looks bad well

54
00:04:06,640 --> 00:04:13,920
here's one theory back when this monitor was announced at e3 2019 the community

55
00:04:10,799 --> 00:04:15,920
was already wondering whether lg's one

56
00:04:13,920 --> 00:04:20,560
millisecond claim was something that the display could achieve reliably or

57
00:04:18,079 --> 00:04:25,919
something it could only do under special circumstances and with overdrive

58
00:04:23,040 --> 00:04:30,960
absolutely cranked so we think that this option is only here so that they could

59
00:04:27,919 --> 00:04:33,919
put one millisecond on the box even if

60
00:04:30,960 --> 00:04:37,919
no one ourselves or lg would actually recommend using that setting but that's

61
00:04:36,400 --> 00:04:42,400
not to say that i don't love this monitor i think it's a great monitor and

62
00:04:40,560 --> 00:04:48,400
not even just because of the response times which do play really clean it also

63
00:04:45,600 --> 00:04:52,479
has a 144hz native refresh rate very decent color accuracy out of the box

64
00:04:50,320 --> 00:04:56,880
thanks to lg's use of nanoceltec which you can learn more about in this video

65
00:04:54,560 --> 00:05:00,800
and it's got variable refresh rate in the form of adaptive sync now some of

66
00:04:58,720 --> 00:05:06,000
you might remember that this monitor was advertised as having g-sync hardware in

67
00:05:03,520 --> 00:05:10,960
it when it was first announced but as you can plainly see the g suffix has

68
00:05:08,720 --> 00:05:16,720
since been dropped from the product name now the monitor still does have a g-sync

69
00:05:14,000 --> 00:05:21,759
sticker on it because it received the g-sync compatible label from NVIDIA so

70
00:05:20,000 --> 00:05:25,520
you'll have variable refresh rate regardless of which graphics team you

71
00:05:23,680 --> 00:05:29,280
play for but you'll miss out on some of the extras that would have come with a

72
00:05:27,280 --> 00:05:34,639
g-sync hardware module and full certification like an unlimited variable

73
00:05:31,759 --> 00:05:38,400
refresh window and 165 hertz overclocking which i guess brings us

74
00:05:36,160 --> 00:05:42,960
perfectly then to the 27 gl850s downsides the first is the lack of HDR

75
00:05:41,919 --> 00:05:48,320
now technically speaking this monitor does

76
00:05:45,440 --> 00:05:53,759
support HDR in that it can accept an hdr10 input source and you can flip HDR

77
00:05:51,440 --> 00:05:58,960
on in Windows however the peak brightness is just 350 nits so it

78
00:05:56,479 --> 00:06:04,160
doesn't even qualify for vasa's lowly display HDR 400 certification similarly

79
00:06:02,000 --> 00:06:08,160
it doesn't have any local dimming to deepen the dark parts of the scene now

80
00:06:06,240 --> 00:06:13,440
honestly speaking i'm not that bothered because HDR on pc still

81
00:06:11,280 --> 00:06:17,919
has some software issues and even premium full array local dimming HDR

82
00:06:15,440 --> 00:06:22,800
monitors like the one i have at home can still suffer from halos and poor viewing

83
00:06:20,479 --> 00:06:29,039
angles due to the chunky dimming zones moving to the outside the i o is also

84
00:06:25,520 --> 00:06:31,600
just okay one displayport 1.4 two HDMI

85
00:06:29,039 --> 00:06:36,400
2.0 ports and a small hub with two usb 3s and a spot for your microphone so

86
00:06:33,759 --> 00:06:41,120
it's fine but i'd be a lot more jazzed if there was a usbc to enable a single

87
00:06:38,880 --> 00:06:45,360
cable connection to my laptop finally there's the stand the height adjust

88
00:06:43,039 --> 00:06:50,880
feels really smooth it's got tilt and even the less common pivot but curiously

89
00:06:48,720 --> 00:06:55,199
it doesn't swivel i mean this is not a deal breaker for me because you can just

90
00:06:53,039 --> 00:06:58,240
turn the whole thing and usually you would sit right in front of your monitor

91
00:06:56,479 --> 00:07:03,039
so it'll be perfectly aligned and everything it's just

92
00:07:00,160 --> 00:07:07,199
and there's no RGB for gamers another weird omission okay i was mostly kidding

93
00:07:04,960 --> 00:07:11,520
about that last one because on the whole these little concessions did result in a

94
00:07:10,000 --> 00:07:16,400
significantly lower price tag the pre-order price for this puppy is 4.99

95
00:07:13,759 --> 00:07:20,880
which given the feature set feels very reasonable so overall i think this is a

96
00:07:18,800 --> 00:07:25,039
great monitor with all the core features that a gamer cares about and even a few

97
00:07:23,360 --> 00:07:28,000
that they don't so thanks for watching guys if the video sucked you know what
