1
00:00:00,160 --> 00:00:07,440
it finally happened g-sync on oled

2
00:00:03,760 --> 00:00:10,160
that's right g-sync on an oled tv and

3
00:00:07,440 --> 00:00:14,960
today ladies and gentlemen wait

4
00:00:12,320 --> 00:00:19,359
we are going to be trying it so lg sponsored this video thanks guys where

5
00:00:17,279 --> 00:00:24,480
i'm gonna be giving you guys the goods on how this came to be

6
00:00:21,680 --> 00:00:29,119
and taking it for a test drive this is how sandwich enthusiasts must have felt

7
00:00:26,720 --> 00:00:31,679
when someone finally put ham and swiss

8
00:00:30,560 --> 00:00:35,680
together for the first time right because like

9
00:00:33,760 --> 00:00:41,060
just ham that's not that great just swiss it's like bland right

10
00:00:38,399 --> 00:00:46,030
swiss

11
00:00:49,120 --> 00:00:54,800
while we get set up oh wow okay uh

12
00:00:53,440 --> 00:01:00,960
we'll go through some background information g-sync is nvidia's name for the variable

13
00:00:58,879 --> 00:01:06,960
refresh rate gaming technology that they pioneered that reduces visual anomalies

14
00:01:03,920 --> 00:01:09,200
like tearing stuttering and lag allowing

15
00:01:06,960 --> 00:01:14,080
games to look their best and feel super responsive and oled is a display tech

16
00:01:12,159 --> 00:01:18,320
that has a handful of advantages over traditional lcd

17
00:01:15,840 --> 00:01:24,080
so for one because every pixel emits its own light all the way from 700 to 800

18
00:01:21,280 --> 00:01:29,040
nits down to completely off that means it's got perfect black sand

19
00:01:27,119 --> 00:01:34,400
infinite contrast for another thing the pixel response

20
00:01:31,520 --> 00:01:40,320
times are actually closer to that of a crt or a plasma which means that there's

21
00:01:37,600 --> 00:01:45,840
no smearing during fast movement and finally oled offers very competitive

22
00:01:43,280 --> 00:01:52,240
color performance so this particular unit has a 10 bit panel and boasts

23
00:01:48,720 --> 00:01:54,320
nearly 99 coverage of the dci color

24
00:01:52,240 --> 00:01:58,719
space oh yeah i guess one other benefit if you're into it is oled panels can be

25
00:01:57,040 --> 00:02:02,799
super thin because they don't need all those layers there's no backlight behind

26
00:02:00,560 --> 00:02:08,479
it well that's just great except for one small problem

27
00:02:05,280 --> 00:02:11,120
for variable refresh rate or g-sync to

28
00:02:08,479 --> 00:02:17,200
work the graphics card from your gaming system has to be able to communicate

29
00:02:14,480 --> 00:02:21,520
with your display otherwise how on earth would your tv know oh hey there's a new

30
00:02:19,520 --> 00:02:25,840
frame ready for me and how would your graphics card know okay we're clear to

31
00:02:23,520 --> 00:02:30,560
send a new frame now on the pc to solve this problem we use displayport which is

32
00:02:28,319 --> 00:02:35,280
royalty free carries more bandwidth generation for generation has a locking

33
00:02:32,959 --> 00:02:41,040
connector and has supported this critical bi-directional communication

34
00:02:37,680 --> 00:02:42,959
with an open basa standard for years

35
00:02:41,040 --> 00:02:48,800
thing is in the consumer electronics industry we're still relying on hdmi so

36
00:02:46,480 --> 00:02:53,519
amd's solution to this problem was to create a proprietary extension to

37
00:02:51,120 --> 00:02:57,760
support adaptive sync over this connection relying on their market share

38
00:02:55,680 --> 00:03:03,360
and home gaming consoles like the xbox and playstation to drive tv manufacturer

39
00:03:00,400 --> 00:03:08,800
adoption nvidia meanwhile has evidently been playing the waiting game so

40
00:03:05,760 --> 00:03:12,480
let's talk about the feature of this tv

41
00:03:08,800 --> 00:03:13,680
that makes the magic happen and it's all

42
00:03:12,480 --> 00:03:21,920
over here every one of the four hdmi ports on this

43
00:03:16,239 --> 00:03:22,879
tv is hdmi 2.1 and hdmi 2.1 is flippin

44
00:03:21,920 --> 00:03:28,519
sick it nearly triples the bandwidth of hdmi

45
00:03:25,200 --> 00:03:32,239
2.0 allowing 4k tvs to run it up to

46
00:03:28,519 --> 00:03:33,760
120 hertz at full resolution without any

47
00:03:32,239 --> 00:03:38,319
frame interpolation or anything like that it supports e-arc for better sound

48
00:03:36,400 --> 00:03:43,680
quality through supported sound bars and speakers it allows the automatic

49
00:03:40,560 --> 00:03:46,000
detection of latency sensitive devices

50
00:03:43,680 --> 00:03:49,760
like for example a game console so that your games won't feel floaty or laggy so

51
00:03:48,640 --> 00:03:55,599
it'll just go into game mode automatically and on supported devices

52
00:03:52,959 --> 00:04:01,439
it allows vrr or variable refresh rate operation over an industry standard

53
00:03:58,400 --> 00:04:02,560
implementation rather than a proprietary

54
00:04:01,439 --> 00:04:07,040
extension and what's cool is it actually took lg

55
00:04:04,720 --> 00:04:12,959
building their own hardware in order to get these cool hdmi 2.1 features like 4k

56
00:04:10,799 --> 00:04:17,440
120 hertz and variable refresh rate working on their 2019 oleds

57
00:04:15,920 --> 00:04:20,880
now with that said oh

58
00:04:18,959 --> 00:04:24,720
we're not going to be able to try all of them today

59
00:04:22,000 --> 00:04:30,080
because even the most state-of-the-art computer that exists now

60
00:04:26,880 --> 00:04:33,120
doesn't have hdmi 2.1 in fact there

61
00:04:30,080 --> 00:04:36,639
isn't a single consumer device that

62
00:04:33,120 --> 00:04:39,440
outputs an hdmi 2.1 signal

63
00:04:36,639 --> 00:04:43,520
so the best we can do is uh one of these

64
00:04:40,880 --> 00:04:46,160
fortunately that's not too shabby all right

65
00:04:44,639 --> 00:04:51,440
so let's see if this picked up immediately here i kind of doubt it will

66
00:04:48,720 --> 00:04:57,600
we're definitely at 4k but we are at 30 hertz right now is that gonna fit

67
00:04:53,840 --> 00:05:00,080
there we go okay so it knew it was hdr

68
00:04:57,600 --> 00:05:06,560
capable but the computer itself did not know to switch to hdr when the tv

69
00:05:03,040 --> 00:05:07,840
uh okay that's fine all right so i wanna

70
00:05:06,560 --> 00:05:13,680
know if it's just gonna show up

71
00:05:11,039 --> 00:05:18,400
and no it's not so that actually makes sense because it was only recently that

72
00:05:15,840 --> 00:05:24,479
nvidia released a software update to their 20 and 16 series graphics cards

73
00:05:21,520 --> 00:05:29,840
allowing their hdmi ports to utilize the variable refresh rate feature

74
00:05:27,280 --> 00:05:37,199
from hdmi 2.1 so then they actually went and validated

75
00:05:32,880 --> 00:05:39,680
lg's entire 2019 lineup of oled tvs as

76
00:05:37,199 --> 00:05:45,440
g-sync compatible so with this update then we're not getting any of the extra

77
00:05:42,000 --> 00:05:47,039
bandwidth that a true hdmi 2.1 graphics

78
00:05:45,440 --> 00:05:52,800
card could push so we're not going to be running at 4k 120 hertz

79
00:05:50,479 --> 00:06:01,759
but we are getting support for up to 1080p or even 1440p at 120 hertz or 4k

80
00:05:58,320 --> 00:06:05,600
at 60hz and all of those are with g-sync

81
00:06:01,759 --> 00:06:09,440
down to 40 fps so that's either a 40 to

82
00:06:05,600 --> 00:06:12,880
60 fps window or 40 to 120

83
00:06:09,440 --> 00:06:15,919
and with a theoretical hdmi 2.1 graphics

84
00:06:12,880 --> 00:06:19,039
card we could actually run 4k 120 hertz

85
00:06:15,919 --> 00:06:20,720
40 to 120 window enough chit chat though

86
00:06:19,039 --> 00:06:26,080
let's get this installed and see if it works as advertised wait sorry one last

87
00:06:23,759 --> 00:06:30,240
thing so in order to ensure that g-sync is gonna work we need to apply the

88
00:06:27,600 --> 00:06:33,280
latest update for our tv as well as our graphics drivers so we'll just give that

89
00:06:32,160 --> 00:06:39,680
a couple minutes okay so we're in game mode

90
00:06:36,479 --> 00:06:42,000
input latency looks perfectly reasonable

91
00:06:39,680 --> 00:06:45,280
let's go ahead and fire up our control panel and see if g-sync shows up if it

92
00:06:44,080 --> 00:06:51,919
doesn't i actually don't really know what to do right now fortunately it does

93
00:06:47,840 --> 00:06:55,600
set up g-sync man this makes me so

94
00:06:51,919 --> 00:06:57,759
excited right now g-sync oled

95
00:06:55,600 --> 00:07:01,440
and of course hdr

96
00:06:59,599 --> 00:07:05,759
so what's crazy is that

97
00:07:02,639 --> 00:07:08,720
previously nvidia has differentiated

98
00:07:05,759 --> 00:07:10,720
regular g-sync from g-sync ultimate with

99
00:07:09,520 --> 00:07:17,599
hdr but this is regular g-sync compatible but because

100
00:07:14,880 --> 00:07:21,440
it's an hdr tv we should be able to g-sync hdr on it

101
00:07:20,400 --> 00:07:29,199
okay i gotta just chill out and actually launch a game so we're gonna know real

102
00:07:25,199 --> 00:07:30,479
quick if hdr is working or not hey there

103
00:07:29,199 --> 00:07:35,120
we go okay looks like when we updated the tv

104
00:07:32,960 --> 00:07:38,880
it got a little confused hurt itself in its confusion and windows disabled hdr

105
00:07:37,280 --> 00:07:45,120
okay let's try that again look at that launching a game

106
00:07:42,080 --> 00:07:47,039
boom so they're actually using a special

107
00:07:45,120 --> 00:07:51,599
line refresh rather than frame refresh method that allows the input latency to

108
00:07:49,360 --> 00:07:57,440
be even lower than it otherwise would be and that is feeling real good

109
00:07:54,080 --> 00:07:59,039
for 60 fps that is freaking awesome so

110
00:07:57,440 --> 00:08:03,840
we're in game it looks great

111
00:08:00,960 --> 00:08:09,280
but let's do a slow pan my controller is going to help me with this to see just

112
00:08:05,840 --> 00:08:13,840
how smooth it is that is about as butt

113
00:08:09,280 --> 00:08:13,840
trees move as it gets my friends

114
00:08:14,560 --> 00:08:22,160
especially when you consider that we're running at only 60 fps

115
00:08:19,440 --> 00:08:28,000
hdr is definitely working well

116
00:08:23,360 --> 00:08:30,560
it's exactly what i expected it to be

117
00:08:28,000 --> 00:08:33,919
hdr and oled together at last

118
00:08:32,399 --> 00:08:39,839
can i oh oh and i'm dead oh and face on the rock

119
00:08:37,680 --> 00:08:44,159
okay as usual it doesn't make you a better

120
00:08:41,279 --> 00:08:49,839
gamer but boy does it ever look good however playing games at 4k 60fps

121
00:08:47,360 --> 00:08:52,880
honestly isn't the thing i was most interested in

122
00:08:51,519 --> 00:08:59,120
let's go ahead and change things up a little bit here all right so now it gets

123
00:08:55,200 --> 00:09:02,080
even better 2560 by 1440 120 hertz is

124
00:08:59,120 --> 00:09:04,399
kind of um for nvidia anyway they're like

125
00:09:02,880 --> 00:09:09,040
best case scenario here but the thing that was weird to me

126
00:09:06,000 --> 00:09:10,800
is that that's not a resolution that we

127
00:09:09,040 --> 00:09:16,080
can use their new integer scaling feature on so there's gonna be some

128
00:09:13,519 --> 00:09:21,279
interpolation now with that said from our experience with 4k and 5k desktop

129
00:09:19,040 --> 00:09:25,600
displays we have found that running at non-native resolutions is not nearly as

130
00:09:23,760 --> 00:09:29,279
noticeable as it used to be you know back when you're running at 1280x1024 or

131
00:09:27,839 --> 00:09:34,560
whatever the case may be so i am really curious to see how this

132
00:09:32,399 --> 00:09:41,120
looks from uh from a normal viewing distance and still at the desktop this

133
00:09:38,560 --> 00:09:46,800
does not look great like text is not very sharp so you can you can really see

134
00:09:44,240 --> 00:09:50,880
like some jaggies on the text one thing actually that we can use this to show

135
00:09:48,800 --> 00:09:56,240
though is check that out unlike on an lcd there's no smearing

136
00:09:53,760 --> 00:10:01,440
even with white text on a fully black background like you can really read the

137
00:09:58,320 --> 00:10:03,680
text as i'm moving it around

138
00:10:01,440 --> 00:10:07,760
hopefully game once you know the whole scene is in

139
00:10:05,760 --> 00:10:13,279
motion that those little jaggies are not that noticeable let's give it a shot

140
00:10:09,839 --> 00:10:16,240
guys i gotta say 120 fps locked like we

141
00:10:13,279 --> 00:10:20,720
can do some six move pans now that is unreal

142
00:10:17,760 --> 00:10:22,880
no tears no stutters and

143
00:10:21,600 --> 00:10:27,360
it just feels crazy responsive right we're

144
00:10:25,360 --> 00:10:31,279
supposed to be looking at the uh the resolution compromise so here let's

145
00:10:29,360 --> 00:10:35,279
maybe we can have a look at her hair if we get in on a bit of a

146
00:10:33,200 --> 00:10:40,320
close-up here so you know what i can see a bit of a reduction in the

147
00:10:37,680 --> 00:10:45,519
definition of her hair for example but on anything that's at kind of a

148
00:10:42,880 --> 00:10:50,160
normal distance from the camera it's not too noticeable i'd say honestly the only

149
00:10:48,399 --> 00:10:54,880
thing that i would do here is add maybe a touch of sharpening filter but i would

150
00:10:52,399 --> 00:10:59,440
definitely take this over 1080p and i would also take 120fps over 60fps any

151
00:10:58,240 --> 00:11:03,600
day of the week if you guys want to see the full details of that you can check out this video

152
00:11:02,320 --> 00:11:08,800
over here of course this is just tomb raider though it's not exactly the most latency

153
00:11:06,800 --> 00:11:12,640
sensitive game so let's get a shooter up here and see how that feels

154
00:11:11,440 --> 00:11:16,800
so to have a look at something a little bit more latency sensitive i fired up

155
00:11:14,560 --> 00:11:20,399
the bombsite defense map that we used for our

156
00:11:18,480 --> 00:11:24,560
frame rate versus low frame rate versus high frame rate video and i want to see

157
00:11:22,800 --> 00:11:29,600
what kind of a time i can put up on this particular display

158
00:11:26,560 --> 00:11:31,519
now obviously limiting myself to 120

159
00:11:29,600 --> 00:11:36,079
frames per second compared to the maximum that i had the day that we did

160
00:11:33,120 --> 00:11:40,399
our test which was 240 is i'm not expecting my best time or anything but

161
00:11:38,560 --> 00:11:45,680
as long as i'm pretty close i consider that darn good so that was 29 seconds

162
00:11:42,880 --> 00:11:45,680
let's do one more run

163
00:11:47,720 --> 00:11:54,480
24.23 that's a pretty good time for me

164
00:11:50,880 --> 00:11:54,480
like honestly it feels pretty good

165
00:11:54,560 --> 00:12:01,200
i wish my mousepad was a little bigger but i mean that's my biggest complaint

166
00:11:58,000 --> 00:12:03,440
right now come on

167
00:12:01,200 --> 00:12:07,600
uh 26.31 i mean i'm at the point now where i'm

168
00:12:05,440 --> 00:12:11,040
kind of ready to say that other than that i'm running g-sync

169
00:12:09,440 --> 00:12:14,880
instead of just letting the frame rate be uncapped

170
00:12:12,560 --> 00:12:18,720
like there would be no excuse for me to not be

171
00:12:16,320 --> 00:12:21,519
as competitive as i can be anyway on a display like this

172
00:12:23,040 --> 00:12:27,600
26.31 not bad

173
00:12:26,160 --> 00:12:32,720
all right colton have a seat

174
00:12:30,000 --> 00:12:37,200
what have i done no you're definitely better than me what

175
00:12:34,079 --> 00:12:39,279
do i do what is this this is a gaming tv

176
00:12:37,200 --> 00:12:43,839
roger actually it's just a tv it just happens to have super low input lag and

177
00:12:40,880 --> 00:12:47,839
run at 120 fps at 1440p so you have to

178
00:12:45,600 --> 00:12:51,360
kill what is it 15 of them ed yeah you got to kill 15 of them as fast as you

179
00:12:49,360 --> 00:12:54,000
can and apparently you can do it better than

180
00:12:52,639 --> 00:12:57,519
me so go for it i'm gonna i'm about to get

181
00:12:55,680 --> 00:13:02,320
ready no go for it first off your sensitivity is so high

182
00:13:00,240 --> 00:13:05,279
any time now colton all right okay take it back take it back yeah you

183
00:13:03,760 --> 00:13:11,600
win you win you win you're much better okay terrorists win

184
00:13:08,800 --> 00:13:15,120
all right ed have a seat first

185
00:13:12,480 --> 00:13:15,120
have a seat

186
00:13:18,839 --> 00:13:24,800
21.17 dang all right

187
00:13:22,240 --> 00:13:28,560
i win all right you win all right now let's try a game where both smoothness

188
00:13:27,040 --> 00:13:34,480
and performance are going to matter this one so it says battlefield 5 running at

189
00:13:31,040 --> 00:13:36,720
ultra settings on our rtx 2080 ti is

190
00:13:34,480 --> 00:13:40,000
right within the g-sync window that is going to give us the most benefit out of

191
00:13:38,240 --> 00:13:47,760
this display so we're sitting anywhere from around 55 to

192
00:13:44,040 --> 00:13:49,120
75-80 fps as we're charging this gun

193
00:13:47,760 --> 00:13:52,480
position here so a game like this is exactly where

194
00:13:50,800 --> 00:13:56,240
you're going to get the most benefit out of a display like this because we're

195
00:13:54,079 --> 00:14:03,040
running right in the sweet spot of its g-sync window so anywhere from around 80

196
00:13:59,839 --> 00:14:04,720
down to as low as around 55 frames per

197
00:14:03,040 --> 00:14:09,040
second as you can see we dip to right there so without g-sync that's going to

198
00:14:07,199 --> 00:14:13,440
affect the smoothness of your animation it's going to add tearing or stutter but

199
00:14:10,720 --> 00:14:18,320
with g-sync it won't so for our last trick we've got the classic nvidia

200
00:14:15,519 --> 00:14:23,440
g-sync pendulum demo which simulates swinging between 40 and 60 fps showing

201
00:14:21,440 --> 00:14:27,839
off the way that g-sync smooths it out and of course it's working exactly as we

202
00:14:25,440 --> 00:14:31,519
expect so lg is not billing this thing as a gaming tv per se because it's good

203
00:14:30,639 --> 00:14:38,639
for well anything you could want to do with it but

204
00:14:34,399 --> 00:14:40,720
confirmed it is freaking sick for gaming

205
00:14:38,639 --> 00:14:45,040
my only regret is that their announcement for this technology

206
00:14:42,480 --> 00:14:49,040
actually came out in between me filming and us releasing my video

207
00:14:47,279 --> 00:14:54,240
getting rid of the oled in my living room so that we could uh have a gaming

208
00:14:51,519 --> 00:14:57,760
display in the living room at home so i think it's

209
00:14:55,440 --> 00:15:01,199
probably time for to play tv shuffle and move one of these

210
00:14:59,920 --> 00:15:04,560
to my house so thanks to lg for sponsoring this

211
00:15:03,040 --> 00:15:08,959
video and of course providing the tv that we showed you guys today thanks to you for watching if you guys are looking

212
00:15:07,360 --> 00:15:12,399
for something else to watch maybe check out the video where i first upgraded to

213
00:15:10,959 --> 00:15:17,279
an oled because i go over some of the benefits of oled outside of just gaming
