1
00:00:00,240 --> 00:00:09,040
ah the Sun the Beloved Source of Life on our planet but also deadly it causes

2
00:00:06,640 --> 00:00:15,799
cancer evaporates our water and worst of all makes it hard for me to read my

3
00:00:12,280 --> 00:00:18,760
screen or at least it used to this

4
00:00:15,799 --> 00:00:24,279
monitor from Sun Vision display is the brightest we have ever seen it has no

5
00:00:22,000 --> 00:00:30,920
backlight allowing it to draw just 6 watts of power and measuring over 2200

6
00:00:27,519 --> 00:00:33,000
knits look at how it has Les direct

7
00:00:30,920 --> 00:00:38,960
sunlight compared to a traditional display in fact the more sunlight there

8
00:00:35,760 --> 00:00:41,079
is the more powerful it becomes but

9
00:00:38,960 --> 00:00:48,160
there is a small catch because you see the less sunlight there is the uh less

10
00:00:45,440 --> 00:00:53,760
powerful it becomes but unlike your phone it's not using a sensor to adjust

11
00:00:51,120 --> 00:00:58,559
its output and the trick lies in the panel technology itself and I'll tell

12
00:00:56,680 --> 00:01:03,719
you all about it right after this message from our sponsor MSI experience

13
00:01:01,559 --> 00:01:08,600
stunningly color accurate visuals and blistering Fast Response times with

14
00:01:05,479 --> 00:01:10,360
MSI's new QD OLED monitors plus use

15
00:01:08,600 --> 00:01:14,200
their gaming intelligence app to fine-tune your experience so you're

16
00:01:11,960 --> 00:01:19,520
always locked loaded and ready to go check them out down

17
00:01:16,159 --> 00:01:21,520
below the name of the brand sunvision

18
00:01:19,520 --> 00:01:26,960
display might give you your first clue as to how this monitor works but it's

19
00:01:24,320 --> 00:01:31,960
not solar powered at least not in the way that you think I already said it

20
00:01:29,479 --> 00:01:40,399
doesn't have a backlight so all right lus it's a self aiss of OLED then no

21
00:01:35,560 --> 00:01:42,759
more like no le in fact it uses an LCD

22
00:01:40,399 --> 00:01:47,479
panel but unlike the ones you're used to it has no backlight of any kind it

23
00:01:45,600 --> 00:01:54,320
doesn't even have a front light like this eink monitor from dasung which

24
00:01:50,640 --> 00:01:57,079
seems kind of crazy in 2024 but it isn't

25
00:01:54,320 --> 00:02:02,799
exactly new the Game Boy Color and Game Boy Advance both used LCD displays that

26
00:02:00,000 --> 00:02:08,160
weren't lit so how did we see anything on those they were

27
00:02:05,280 --> 00:02:13,560
reflective just behind the display layer was a mirror likee layer that reflected

28
00:02:10,679 --> 00:02:18,840
ambient light back to you and this monitor operates on the same principle

29
00:02:16,599 --> 00:02:24,120
overall I'd say the specs are not the Highlight here it's 32 in 1080P so the

30
00:02:22,040 --> 00:02:31,519
pixel density is a little on the low side for our Modern Display it's 60 HZ

31
00:02:27,120 --> 00:02:35,360
it has curiously dual HDMI inputs but no

32
00:02:31,519 --> 00:02:38,760
DisplayPort and then it has a usba a

33
00:02:35,360 --> 00:02:40,400
port for charging that's a little weird

34
00:02:38,760 --> 00:02:44,800
I mean built-in hubs we've seen that before charging not so much it has

35
00:02:42,319 --> 00:02:49,640
built-in speakers vase mounting holes old school behind the monitor so you

36
00:02:47,080 --> 00:02:57,040
can't see the labels navigation and the pixel response times are rated at 10

37
00:02:53,599 --> 00:02:59,599
milliseconds really 2/3 of a frame just

38
00:02:57,040 --> 00:03:06,000
to finish the transition let's give it a shot but not here let's take it to its

39
00:03:02,840 --> 00:03:08,280
natural habitat given we normally test

40
00:03:06,000 --> 00:03:12,239
displays in near blackness in order to prevent ambient light from affecting our

41
00:03:10,360 --> 00:03:16,080
measurements we had to get a little creative in order to test this thing

42
00:03:14,400 --> 00:03:20,400
luckily we were graced with a bright sunny day so we brought the monitor

43
00:03:18,400 --> 00:03:25,200
outside to see it in its ideal environment at 100% window size meaning

44
00:03:23,280 --> 00:03:32,799
basically the full screen is entirely white this hits over 2200 nits that is

45
00:03:29,920 --> 00:03:38,720
truly impressive but here's something to think about a white piece of paper in

46
00:03:35,360 --> 00:03:43,120
that same sunlight measured nearly

47
00:03:38,720 --> 00:03:45,239
24,000 nits so there's clearly a massive

48
00:03:43,120 --> 00:03:49,959
amount of light that's being lost before it's reflected back to our eyes with

49
00:03:47,680 --> 00:03:54,599
that said it's still vastly more readable than pretty much any other

50
00:03:52,159 --> 00:04:00,720
display that we could bring outside so is there a use case for this

51
00:03:58,480 --> 00:04:05,920
thing sure no a boat a boat that doesn't get wet

52
00:04:03,239 --> 00:04:09,239
it's not IP rated and while it does a great job of maintaining the readability

53
00:04:07,640 --> 00:04:13,239
of text under very challenging conditions you'll notice that as soon as

54
00:04:11,040 --> 00:04:18,919
you bring up pretty much anything else it um doesn't look that good it's not

55
00:04:17,079 --> 00:04:24,600
because it uses a different panel technology like the e in that we checked

56
00:04:20,880 --> 00:04:27,560
out recently it's an LCD like any other

57
00:04:24,600 --> 00:04:33,160
so what is up with that well for starters the rated contrast is just 25

58
00:04:30,680 --> 00:04:39,520
to1 and under our test conditions we measured under that yikes for reference

59
00:04:37,000 --> 00:04:45,280
guys even without any backlight dimming tricks a typical IPS display these days

60
00:04:42,320 --> 00:04:51,360
would be rated to about a, to one with VA being about five times that and OLED

61
00:04:48,280 --> 00:04:53,160
panels more like a million to one

62
00:04:51,360 --> 00:04:57,759
however it's worth noting that you can have the best contrast ratio in the

63
00:04:55,199 --> 00:05:02,479
world but if your Peak brightness is well below the Environmental conditions

64
00:05:00,479 --> 00:05:07,840
your eyes which are adjusted for sunlight are not going to be able to

65
00:05:04,759 --> 00:05:09,520
perceive that contrast I mean okay here

66
00:05:07,840 --> 00:05:17,360
here this is a perfect example look at my OLED phone right A Million To One my

67
00:05:13,960 --> 00:05:19,800
so the disadvantage for our rlcd is that

68
00:05:17,360 --> 00:05:24,919
it can't really darken or boost its brightness relative to its environment

69
00:05:22,120 --> 00:05:28,520
but kind of like a book what it can do is reflect the conditions of its

70
00:05:26,880 --> 00:05:33,840
environment which keeps it within a usable range for your eyes

71
00:05:30,400 --> 00:05:36,600
so to illustrate this right here looks

72
00:05:33,840 --> 00:05:41,400
black but when we measured it we found that it was over 100 nits which to put

73
00:05:39,360 --> 00:05:46,080
in perspective is brighter than what would have been white on the CRT

74
00:05:43,720 --> 00:05:51,360
monitors in my school computer lab as a kid another disadvantage that stems from

75
00:05:48,759 --> 00:05:57,840
reflecting environmental light is that the display's color performance is also

76
00:05:54,400 --> 00:06:00,319
impacted by factors like time of day and

77
00:05:57,840 --> 00:06:04,840
weather if you were using the this on a patio for instance the color temperature

78
00:06:02,880 --> 00:06:09,520
of the display would change with the rising and setting of the sun I mean

79
00:06:07,840 --> 00:06:14,800
you're probably not going to notice this since your eyes and your brain have god

80
00:06:11,960 --> 00:06:19,680
tier Auto white balance but this lack of consistency means that this thing is

81
00:06:16,960 --> 00:06:25,039
functionally useless for color sensitive work and even if it was accurate enough

82
00:06:22,280 --> 00:06:30,360
the color gamut wouldn't be it managed just

83
00:06:26,120 --> 00:06:33,080
177% of the srgb color space which

84
00:06:30,360 --> 00:06:38,759
doesn't make sense I mean if you're feeding it direct sunlight which is you

85
00:06:35,599 --> 00:06:41,720
know all of the colors why doesn't it

86
00:06:38,759 --> 00:06:46,280
all those colors back out into your eyes well actually that's kind of the problem

87
00:06:44,080 --> 00:06:51,319
it does here's a keyboard towel from LTT Store.com clean yourself up the thing is

88
00:06:49,080 --> 00:06:57,120
if you want to make specific colors you don't want a full spectrum light Cannon

89
00:06:54,199 --> 00:07:02,800
you want fine control over specific wavelengths so a normal mon spectral

90
00:07:00,240 --> 00:07:08,160
distribution has very acute Peaks for green red and blue but the diffuse

91
00:07:06,400 --> 00:07:13,520
spectral power distribution of sunlight means you can't get pure green very

92
00:07:11,160 --> 00:07:18,000
easily combine that with the lack of brightness needed to create some colors

93
00:07:15,319 --> 00:07:22,800
and you've got a recipe for bad color accuracy and I promise you guys digging

94
00:07:20,680 --> 00:07:30,400
around in the comically bad onscreen display is not going to fix it maybe

95
00:07:26,199 --> 00:07:32,919
gaming is good no well you can certainly

96
00:07:30,400 --> 00:07:39,720
play games they aren't even sugar coating how not ideal it is even for a

97
00:07:36,080 --> 00:07:42,000
60hz display the rated 10 milliseconds

98
00:07:39,720 --> 00:07:46,479
of pixel response time means that any fast-paced motion is going to be

99
00:07:43,919 --> 00:07:52,319
noticeably smear to the eye and we found the input latency was best described as

100
00:07:49,680 --> 00:07:55,520
gnarly um it wasn't easy to get a number that's comparable to our other testing

101
00:07:53,879 --> 00:08:00,440
because our latency tester needs to be mounted to the display and uh

102
00:07:58,400 --> 00:08:05,800
inconveniently blocked this one from outputting anything at

103
00:08:03,199 --> 00:08:11,599
all so then you've heard a lot of arguments for not buying the sunvision

104
00:08:08,360 --> 00:08:15,560
rlcd display maybe you're ready for why

105
00:08:11,599 --> 00:08:19,120
it exists well it was a

106
00:08:15,560 --> 00:08:21,479
sign no not that kind this kind

107
00:08:19,120 --> 00:08:26,400
sunvision display specializes in using this technology in applications like

108
00:08:23,599 --> 00:08:31,919
digital signage where honestly it makes a ton of sense I mean how cool would it

109
00:08:29,039 --> 00:08:36,640
be to have your food truck or your golf course weather report be readable in

110
00:08:34,120 --> 00:08:40,880
basically any real world conditions and this is all while consuming a tiny

111
00:08:39,120 --> 00:08:45,800
fraction of the power of a regular display that's pretty cool and business

112
00:08:43,719 --> 00:08:50,800
seems to be going pretty good for them so good in fact that some folks started

113
00:08:48,440 --> 00:08:57,120
buying their signage products to use with their computers and well the

114
00:08:53,640 --> 00:09:00,240
customer's always right right so they

115
00:08:57,120 --> 00:09:02,600
made this except

116
00:09:00,240 --> 00:09:07,600
sometimes the customer isn't right the re monitor is heavily marketed towards

117
00:09:05,399 --> 00:09:14,160
people who suffer from computer vision syndrome and while CVS does exist it's

118
00:09:12,040 --> 00:09:18,519
one of those things where the Nuggets of good information are often buried in

119
00:09:16,519 --> 00:09:24,600
mountains of marketing nonsense and pseudo science for example sunvision

120
00:09:21,760 --> 00:09:29,079
talks about blue light emissions but as we mentioned in our eink monitor review

121
00:09:27,120 --> 00:09:34,480
there isn't strong evidence that blue light emitted from a screen is harmful

122
00:09:31,120 --> 00:09:37,120
at all and when we look at a spectrogram

123
00:09:34,480 --> 00:09:42,399
we can see that because this monitor's back light is effectively a mirror that

124
00:09:39,320 --> 00:09:45,000
is bouncing back broadspectrum sunlight

125
00:09:42,399 --> 00:09:49,680
this thing reflects more blue light towards you then a regular monitor would

126
00:09:50,560 --> 00:09:56,320
emit uh just so you can actually see what we're doing on the monitor we're

127
00:09:54,000 --> 00:10:00,600
going to try and give it enough light to like look like

128
00:09:57,920 --> 00:10:07,800
anything unless happen to use lights that are this bright the re monitor is

129
00:10:04,320 --> 00:10:10,560
just not a good experience indoors it's

130
00:10:07,800 --> 00:10:16,480
usable in a typical office but here go ahead and hit it it's really not bright

131
00:10:14,279 --> 00:10:20,800
and well you probably won't need dark mode if you happen to be a dark mode

132
00:10:18,279 --> 00:10:24,720
kind of person the lack of contrast can make distinct Shades of Gray disappear

133
00:10:23,079 --> 00:10:32,399
faster than a book about gender in a Florida library and this is a real

134
00:10:28,720 --> 00:10:36,959
problem in a 300 Lux office environment

135
00:10:32,399 --> 00:10:40,480
this achieves just 5.2 nits for contrast

136
00:10:36,959 --> 00:10:45,399
pun intended a white sheet of paper is

137
00:10:40,480 --> 00:10:47,360
90 nits so why are we getting under 10%

138
00:10:45,399 --> 00:10:52,760
of the amount of reflected light compared to this it comes down to the

139
00:10:50,040 --> 00:10:59,519
way the panel is made each of the individual pixels consists of a mirror a

140
00:10:55,880 --> 00:11:03,240
transistor and a 10 micromet surrounding

141
00:10:59,519 --> 00:11:05,120
Gap the problem is that the Gap part is

142
00:11:03,240 --> 00:11:10,560
non-reflective and with their current manufacturing capabilities it's non

143
00:11:07,720 --> 00:11:15,440
shrinkable so under a microscope only about 80% of the surface area of the

144
00:11:12,800 --> 00:11:19,680
display is reflective at all and even the parts that are reflective have to

145
00:11:17,320 --> 00:11:23,480
deal with a lot of loss have you ever taken apart a regular Monitor and

146
00:11:21,480 --> 00:11:28,040
noticed how flipping bright the backlight is compared to the final image

147
00:11:26,120 --> 00:11:33,279
well that's because every layer of a display including po izing filters the

148
00:11:30,560 --> 00:11:38,760
glass the diffusers there's more layers than You' think and all of them are

149
00:11:35,680 --> 00:11:40,680
lossy and in our reflective display

150
00:11:38,760 --> 00:11:47,399
light has to travel through all of those layers not once but twice so to even

151
00:11:45,440 --> 00:11:52,200
achieve the brightness that they have sunvision had to compromise on pixel

152
00:11:49,720 --> 00:11:57,000
density optimizing their mirror to Gap ratio and they had to go with a color

153
00:11:54,519 --> 00:12:01,800
filter that allows more light through but compromises color saturation

154
00:11:59,800 --> 00:12:06,120
we were curious if this was also the reason that they left off having a front

155
00:12:03,880 --> 00:12:11,320
light which might have improved indoor usability but at the expense of probably

156
00:12:08,720 --> 00:12:15,120
needing yet another diffusion layer when we asked sunvision though it turns out

157
00:12:13,320 --> 00:12:20,120
that it was because their customers said they wouldn't use it and didn't want it

158
00:12:17,560 --> 00:12:24,240
which is fair enough I guess since if I can afford one of these I can also

159
00:12:22,120 --> 00:12:32,360
afford a waterfront property with floor to ceiling Windows to let the sun shine

160
00:12:27,360 --> 00:12:35,720
through on it even on special for

161
00:12:32,360 --> 00:12:37,560
$1,499 this thing ain't cheap which

162
00:12:35,720 --> 00:12:42,600
would bother me less if it wasn't for the budget feeling build quality I mean

163
00:12:40,320 --> 00:12:46,320
admittedly I have no idea what the margins are like on a niche product like

164
00:12:44,760 --> 00:12:51,199
this obviously they aren't making that many of them but even dasung was able to

165
00:12:48,959 --> 00:12:56,079
produce what felt like a more complete package for their e in display that

166
00:12:53,959 --> 00:12:59,959
being said if you can afford it and you absolutely must not have a backl in your

167
00:12:58,760 --> 00:13:03,720
monitor I think I would recommend this one over

168
00:13:01,839 --> 00:13:08,519
an e in display thanks to its better Motion Performance and that would be

169
00:13:06,320 --> 00:13:14,399
especially true if they do a V2 that has some kind of flicker-free LED front

170
00:13:10,839 --> 00:13:14,399
light as it is now

171
00:13:14,519 --> 00:13:21,839
though I think I'll stick to regular monitors you can get some absolutely

172
00:13:19,639 --> 00:13:24,959
sick displays for this kind of money and we're going to have this link down below
