00:00:00,160 --> 00:00:07,759
there's an oft-repeated piece of advice among av enthusiasts if an HDMI cable is

2
00:00:05,200 --> 00:00:11,599
built to spec and it functions properly there's no reason to spend extra money

3
00:00:09,519 --> 00:00:16,080
on something fancy because a digital transmission isn't nearly as susceptible

4
00:00:13,759 --> 00:00:20,640
to interference as an school analog connection in other words

5
00:00:18,000 --> 00:00:24,320
it basically works or it doesn't indeed we did a video on our channel a while

6
00:00:22,400 --> 00:00:28,400
back that showed how silly certain over-engineered HDMI cables can be

7
00:00:26,960 --> 00:00:33,440
but that doesn't mean it's always a great idea to buy the cheapest most bare

8
00:00:30,880 --> 00:00:36,880
bones cable either so to find out what actually matters when buying an HDMI

9
00:00:35,200 --> 00:00:40,399
cable we spoke to you green a manufacturer of HDMI cables and we'd

10
00:00:38,800 --> 00:00:45,040
like to thank them as well as phillips aoc and david chef for his translation

11
00:00:43,120 --> 00:00:49,280
services so it turns out that using the correct material inside of an HDMI cable

12
00:00:47,600 --> 00:00:55,680
can make a big difference but that doesn't mean that you should go out and find cables with platinum unoptimium

13
00:00:53,199 --> 00:00:59,600
alloy or whatever other nonsense cheaply made HDMI cables sometimes use steel

14
00:00:58,160 --> 00:01:03,680
which isn't a particularly good conductor meaning it's something that

15
00:01:01,359 --> 00:01:07,920
you should generally avoid you might see cables that are made of copper coated

16
00:01:05,519 --> 00:01:13,119
steel but these aren't really any better instead go for cables with pure copper

17
00:01:10,640 --> 00:01:16,799
wiring inside the good news however is that copper cables aren't super

18
00:01:14,880 --> 00:01:21,280
expensive and you don't need to get anything higher grade such as silver

19
00:01:19,280 --> 00:01:25,600
plated copper what then becomes important is how thick the wiring is

20
00:01:23,680 --> 00:01:29,360
inside which is measured by something called a gauge number and

21
00:01:27,280 --> 00:01:34,159
counterintuitively a lower number means a thicker wire as a general rule of

22
00:01:31,920 --> 00:01:39,840
thumb your cable length shouldn't exceed 1.5 meters with a thin 32 gauge wire but

23
00:01:38,159 --> 00:01:43,680
as you go thicker and thicker you can safely have a longer and longer cable

24
00:01:41,759 --> 00:01:48,560
run without having to worry about signal attenuation or interference because your

25
00:01:46,000 --> 00:01:53,200
cables are too thin as indicated by this helpful chart however you won't find

26
00:01:50,799 --> 00:01:58,000
much thicker than 24 gauge since at that point the cables simply become too thick

27
00:01:55,600 --> 00:02:02,000
and difficult to bend another thing to consider is the connectors on the end of

28
00:02:00,000 --> 00:02:06,159
the cable gold plating is better if you can find it but take note that i'm not

29
00:02:04,240 --> 00:02:10,879
talking about the large part on the outside that manufacturers often color

30
00:02:08,560 --> 00:02:15,440
gold to give the cable a more premium look i'm talking about the actual

31
00:02:13,040 --> 00:02:19,200
contacts on the inside of the connector gold plating won't really affect your

32
00:02:17,040 --> 00:02:23,680
performance but it will give you better longevity as the gold is an effective

33
00:02:21,440 --> 00:02:27,840
barrier against wear and corrosion especially if you're unplugging and

34
00:02:25,200 --> 00:02:31,360
replugging the cable quite often which i don't do because my tv is too close to

35
00:02:29,520 --> 00:02:35,200
the wall once you've found a cable made with good materials try and find out if

36
00:02:33,200 --> 00:02:39,040
it's been tested to work with a wide variety of equipment some cheaper cables

37
00:02:37,519 --> 00:02:42,959
are only tested with a couple of monitors so they might not play very

38
00:02:40,959 --> 00:02:46,879
nicely with your gadgets if you're running them in any kind of setup that

39
00:02:44,640 --> 00:02:51,519
isn't super straightforward such as with an HDMI splitter if the manufacturer

40
00:02:49,680 --> 00:02:55,840
doesn't list testing methods on their website read reviews and and find out if

41
00:02:54,080 --> 00:03:00,080
any other customers have had problems with compatibility and on the subject of

42
00:02:58,000 --> 00:03:05,519
compatibility make sure you're buying a premium high speed cable if you want 4k

43
00:03:02,879 --> 00:03:10,560
at 60hz or HDR these have a speed of around 18 gigabits per second as opposed

44
00:03:07,840 --> 00:03:14,480
to the 10 gigabits of the more standard high speed cable not premium high speed

45
00:03:12,959 --> 00:03:17,920
and you'll need the extra bandwidth to enable higher frame rates and deeper

46
00:03:16,080 --> 00:03:22,159
colors interestingly manufacturers actually made these faster cables not

47
00:03:19,840 --> 00:03:26,800
with exotic materials or radical design changes but simply by improving the

48
00:03:24,000 --> 00:03:31,519
manufacturing process to minimize small defects in the copper that can hurt the

49
00:03:28,800 --> 00:03:36,400
signal increase latency and introduce interference however faster speeds still

50
00:03:34,159 --> 00:03:41,280
mean a smaller margin for error so if you're trying to use ultra high speed 48

51
00:03:39,200 --> 00:03:45,760
gigabit cables to get the most out of HDMI 2.1 for example you probably don't

52
00:03:44,080 --> 00:03:50,480
want to get a cable longer than three meters just remember generally speaking

53
00:03:48,319 --> 00:03:54,000
shorter and thicker is better just ask kim k
