LG admits premium display fails near wi-fi
- deleted 10y ago[deleted]
- finid 10y agoAha! I observed the same thing late last year when I use a foldable wristpad with magnets inside that I got from an AT&T booth at a tech conference. So this is not limited to that specific LG display. Mine is an LG 24MA32D that I bought about 3 years ago.
- joecool1029 10y agoOne wonders if the 2.4ghz USB3 interference [1] also messes with it, keep your external drives away! [1] http://www.intel.com/content/www/us/en/io/universal-serial-bus/usb3-frequency-interference-paper.html http://www.intel.com/content/www/us/en/io/universal-serial-b...
- minimaxir 10y agoI have a USB-C to USB-A hub and a USB 3.0 external HD connected via converter both connected to my LG 5k. No issues so far on either end. My network is mostly 5Ghz w/ a Google Wifi

- coldpie 10y agoHow fucking hard is it to make a competent display? I feel like the A/V market is ripe for disruption. Sell a quality line of displays with no "smart" crap and a relatively low-cost receiver with no "smart" crap, a usable front-end with tons of A/V features and a dozen inputs of different types. This must be harder than I think it is, because no one is doing it.
- maxxxxx 10y agoI think "smart" stuff can be produced cheaply but sold expensively. It may be hard to make money on a basic display.
- gshulegaard 10y agoThis is my suspicion as well. It's also why the "top of the line" TVs from a display specification perspective also have "SMART" baked in as well. That said, is this LG issue because it has smart stuff or because it lacks appropriate shielding? The article kind of hints that it's a lack shielding.
- digikata 10y agoI don't know about most consumers, but the "smart" stuff is a big product negative feature when I'm shopping. I'd much rather add an external device of my choosing, Roku or Apple TV or something else than use the TV internal "smart" apps/channels which may or may not get updated. Now if some TV added a nice little shelf space, or mount point for an external box behind the TV - I would think that would be a selling feature. You can just not activate/use the feature, but I find I keep tripping over the button on the remote.
- maxxxxx 10y agoSomehow this stuff seems to sell. Same for Android phones. I hate that every manufacturers feels they need to add some crappy custom UI on top of stock Android but they keep doing it.
- thwarted 10y agoFor the same reason ISPs and telcos have traditionally included "value-adds" on their Internet connectivity, like email accounts, portals, news, business websites, etc, etc, etc, because they don't want to become commodity "dumb pipes". The phone manufacturers need to create and push non-standard (and often broken) app launchers and branded skins in order to differentiate, otherwise they'd just be another Android phone maker, rather than, say, the manufacturer of the Samsung phone.
- AdmiralAsshat 10y ago"Changing the location or positioning of either the router or the display should resolve the issue," it said. "Doctor, it hurts when I do this!" "Don't do that!" --- The article said future models will include additional shielding. Will the people who bought the earlier models be allowed to exchange, or is the above non-solution all they get?
- oddevan 10y agoThe buzz on the Mac web is that they can retro-fit old displays. Don't know if it'll be an exchange or what. From MacRumors: https://www.macrumors.com/2017/02/03/lg-27-inch-5k-display-router-fix/ https://www.macrumors.com/2017/02/03/lg-27-inch-5k-display-r... > Owners affected by the issue are advised to get in touch with Apple, LG, or their reseller to arrange for a repair.
- joecool1029 10y agoI'm guessing they just staple some of this shit on: https://www.lessemf.com/fabric5.html#1246 https://www.lessemf.com/fabric5.html#1246 "yep, that should do it, all better now!"
- mark_l_watson 10y agoThat seems like a bad flaw they should have detected during product testing. Rushed to get to market. I bought their smaller 4K monitor last week and so far, except for a not perfectly fitting usb-c socket, all is great so far. I love it.
- grenoire 10y agoWasn't this front page just the other day? Users basically mentioned that the monitor itself was great except for this interference issue. https://news.ycombinator.com/item?id=13530709 https://news.ycombinator.com/item?id=13530709
- halomru 10y agoI assume this slipped through because the required certifications don't include rigorous requirements for electromagnetic interference on unlicensed bands? Or was this supposed to be caught in required testing?
- tzs 10y agoI believe the required testing for FCC Part 15 certification only covers what your device emits, not how it responds to the emissions of other devices.
- panda88888 10y agoThis isn't new. Honeywell monitor used inside Boeing 737 cockpit failed near WiFi as well. They discovered this defect when in-flight WiFi was introduced. http://aviationtroubleshooting.blogspot.com/2014/10/display-units-on-boeings-flight-deck.html http://aviationtroubleshooting.blogspot.com/2014/10/display-... Edit: added link and clarification that the display is used inside the cockpit.
- Kluny 10y agoI see this label on most electronic devices I own: "This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation." [1] If the display comes with that label, shouldn't that be enough to make LG subject to a class action suit, or at least a huge fine from the FCC? Or is the FCC another agency that's lost its teeth this year, along with the FDA and the EPA? [1] https://www.law.cornell.edu/cfr/text/47/15.19 https://www.law.cornell.edu/cfr/text/47/15.19
- panda88888 10y agoI think LG is in the clear. My understanding is that as owner of the LG display, you simply cannot sue your WiFi router manufacturer for messing up your monitor, hence the "must accept any interference ... including interference that may cause undesired operation." Part 15 doesn't guarantee that the monitor will continue to operate under interference.
- ghostly_s 10y agoIndeed. My understanding is those terms mean your device can't defensively interfere with the operation of other devices because they are causing undesired operation of your device.
- delecti 10y agoI'm not sure why you'd have grounds to sue on that basis. Isn't this just an example of undesired operation caused by interference received? It's warning you that it must accept that interference. Shouldn't this mean that all wifi devices are causing harmful interference in violation of that text? I'm not trying to be snarky either. Am I just completely misunderstanding the meaning of that FCC warning?
- Kluny 10y agoI'm not sure, I was just trying to clarify. You and the other poster cleared it up, thanks.
- bitmapbrother 10y agoLG has been plagued with quality control issues. Their Android phones are known to suffer from boot loop problems.
- tfe 10y agoThis is the biggest bummer with Apple existing the display business. Say what you will about them but at least the engineering is competent.
- gldalmaso 10y agoCompetent but not flawless (antennagate, bendgate). So maybe not so different from LG.
- stdclass 10y agoSlightly offtopic: can somebody recommend me a 4K display for programming (around 28-32inches)?
