[@whasian1487]

In a work environment where I'm dealing with thousands of each type, I find myself preferring HDMI because it either works or it doesn't. The DP cables renegotiating signal is a huge pain. For example, a monitor randomly going black for a few seconds then coming back up. Users will often deal with the issue for a while until it annoys them enough to contact the IT department. As opposed to an HDMI cable where their screen goes black and stays black and instead of contacting us, they'll grab a spare HDMI cable and try replacing it on their own.

[@remington8115]

Also when a cable is clearly dead peolpe will throw them away, when cables kind of work they end up getting stashed and used again to cause issues.

Makes sense for that kind of environment. You want everyone to be working or clearly not working. Diagnosing an issue is time and money. As an individual user, I definitely prefer DP.

[@pmackni]

Yeah, I can get that. Our firm's IT seems to prefer DP, but I think that's at least partly due to the lack of HDMI ports on the graphics cards they kit our designer machines with (usually only 1 as opposed to 3 DP, whereas most consumer cards have 1 DP and 3 HDMI).

[@whasian1487]

[@Muscleduck]

A quick thought: DP problems aren't always the cable's fault. I have a Dell U2711 and it has a notorious fault with DP not waking up the screen when you turn it off and on again. It actually needs a power cycle to turn on properly. This is mediated by using a cable where (if I recall correctly) pin 19 isn't connected. I believe it is the issue Linus talks about with DP_POWER being connected. The fact that these cables ar readily available tells me that there is more monitors with this issue.

One of which was that the PC could fail to power on at all, with a diagnostic LED being lit on the motherboard even with the PSU unplugged! Because yes, pin 20 is for power, and things can go wrong when both ends send power through it, or worse things can happen when one end is not sending power. For a moment, I thought my PC was toast, which I heard is a possible outcome, but thankfully it was not.

This was a very informative video! I walked away from the HDMI video not really understanding what the actionable take away should be. But this video has two take aways for me: I should opt for DP over HDMI when possible for the reliability, and my new monitor occasionally turning off and then on could likely be the bundled DP cable. Thanks LTT!

[@James-Purdy]

I've always felt the DisplayPort standard must have been inherently flawed in some way that created majorly non-durable cables. I've also had Thunderbolt 2 cables (from apple) fail after not much use or strain which is definitely not the case with any of my USB-C connector thunderbolt 3 cables. I've just ended up going with "VESA Certified" DisplayPort cables in the recent past because I've had the most luck with those.

[@sheik124]

Ditto on the "VESA Certified" cables. Used to think having the "|D" mark on the cable automatically meant they were VESA Certified, but I looked up the P/N of the cables that came with my HP monitors, every single one of which gave me drop-outs once MST was involved, and they weren't on their list.

[@davidholland6164]

What's really nice about this video is I bought the silkland 6.6 foot display port cable off of amazon way back in the beginning of 2022 and I was glad to see that it passed all of it's tests! Glad I don't need Jeffrey to give me my money back

Awesome video! I have always followed the motto of using the cord included with the device as I know for -sure- it has been tested and qualified with the device. Honestly, if they aren't going to include quality cables they should just not include them at all. It's just e-waste and makes their product look bad.

Thank you for this 4:42 Now I know If I used something like an adapter that has output DisplayPort to the input HDMI, This will force and change, could possibly damage the HDMI Input power design that's going into the Monitor or TV set, it may damage it. Think it's just best to keep it simple and just use the Right Port output Design to work only with the Same input Monitor or TV's using the same DisplayPort design.

[@naamadossantossilva4736]

Correct,and that is another reason DP is better.

Well most people use the cables included in the box with their monitors which all failed. I bought a Dell gaming monitor and at 10 bits 165 Hz it occasionally flickers off. Now I know why

[@forum42087]

Great timing LTT! Just setup my new Odyssey G7 S28 and could explain the occasional odd issue I've seen since switching the cables from my own hdmi 2.1 to the dp cable Samsung included. Never used dp before but know they can be finnicky, figured the included cable looked decent quality & even says 8k on the tab so it must be good right? Ha, serves me right! Ordered a replacement & going back to the 2.1 cable til then lol. Cheers Linus👍

[@TinyTaurenRK]

I had the EXACT same issue with my G7. Replaced cable and it worked wonders!

[@forum42087]

I suppose if they are gonna cheapen out anywhere I'd much rather its on the included cable than the panel itself lol.

[@whatdadogdoin7531]

Recently I bought the silkland DP 1.4 6ft cable from Amazon as the previous 3 ft one that I used was constantly causing flickering issues. I noticed that there was tension on the 3 ft cable and it had those locking tabs at the end of the cable which made me think maybe it's not connecting properly to the GPU. So I bought the silkland cable and everything is going good without any issues. Also the Intel gpus have DP 2?? Damn imagine paying $2k for a 4090 and not getting DP 2 🤡

[@metalbillyboy]

I love this type of testing content. Suggestion on how to expand this content in the future, once the lab is up and running: 1. Add a standardized ware & tear test (plug & unplug, bend etc. like a 1000 times with a robotic jig). 2. Impact of interference (power cable run alongside, powerbrick next to it etc.)

[@Jixxor]

The cable that came with my AOC monitor (DP 1.2) did exactly what was described at 8:41. I genuinely thought that the monitor must be broken and had already contacted the seller when I bought another cable due to my impatience and that one actually works fine to this day.

Cool study. I'd like to see LMG hire a statistician or data scientist that can help design these experiments and benchmarks. For example, a lot of your past videos have mentioned two competing products to be within "margin of error" but are you really sure that the two products are not different? In this case, I would have run a positive and negative control to make sure the machine is working. In addition, all tests have a false positive and false negative rate, and it would be helpful to get sensitivity and specificity figures for your data. It's possible that the machine has a high false positive rate for DisplayPort cables, but we have no way of knowing with the current data.

Good info to have, I find it hard to believe that all of your cables from tab one passed though. I must have bad luck then, out of the many display port 1.4 cables I have purchased over the years not one gave me a smooth experience without dropout for my ultrawide display. I was so fed up that I went to display port's website researched a reasonably priced display port certified cable and purchased one of those. Haven't had any more dropout issues since. I'd be curious to see if use over time has an effect?

[@felicityc]

The grade doesn't matter, but a non-certified cable will mess you up

Had an issue recently running 2 monitors (side with HDMI main with DP) where signal on the main would cut out for a couple seconds, but only at 144hz ddespite being a brand new cable and everything being compatible. Turns out VESA certified cables are wired a little different than non certified where the #20 pin acts as an extra power wire on VESA certified cables, so incase anyone running into that issue check your cable

[@OpDieFietsNL]

Wait so, you fixed it by getting a non-certified cable?

[@123sleepygamer]

Uhm, no, it should be the opposite. You should always buy VESA certified cables to avoid issues, that's what I've gleamed from this and other people's reports. I think you have your info backwards. NON VESA can have the power pin wired.

"Those locking tabs [...] they are nice to have though" NO THEY ARE NOT! Outside of broadcast use where locking connectors are a must, those tabbed mother effers are the worst thing to happen to a cable in a long time. Trying to remove a cable from a monitor with those tabs is HELL and puts unnecessary strain on the ports in the monitor. I buy cables exclusively without them now. They're awful. xD

[@robertt9342]

I disagree. Maybe the tabs on the cables you have are garbage, or you are trying to unplug it like an HDMI cable. Anecdotally, I have ZERO issues with the tabs unplugging every other day and I know the cables are always securely connected. Besides outside of a “broadcast” use, most people aren’t unplugging often.

This is rather interesting to me. I work in IT and have fairly consistent issues with monitors dropping signal only to work again on reboot or they will simply flash off and back on. For quite a while, I was chalking it up to the Thunderbolt G2 (HP) docks we were using. I never considered that the issue would be with the OOB display port cable. Dumb, I know.

4:41 - Small clarification: With newer HDMI standards (HDMI 2.0 and above?), they do actually use the "Clock" pair to send data, so they could get the full 18 Gbps, and now up about 48 Gbps. As always, the manufacturers still keep making cable standards that don't have quite enough wires for future-proofing. (here's looking at you, USB. lol) So they had to find lots of workarounds to make the faster HDMI standards work with older style cables. The amount of bandwidth they have now is staggering, considering how cheaply made a lot of the cables are.
