Bright spot in a dark day. Looking forward to watching.

t

thank you, I needed something else to focus on

Jacob

Hope everybody’s doing alright. Desperately trying to hold it together over here.

zmk

Really appreciate you. I've been struggling a lot today and having a new video of yours to enjoy will help to distract from everything else.

t3hbeowulf

Indeed. Woke up this morning, slightly hung over, saw the headline and just... ┻⁠┻⁠︵⁠ヽ⁠(⁠`⁠Д⁠´⁠)⁠ﾉ⁠︵⁠┻⁠┻

t3hbeowulf

Thank you for this bright spot. 🍻

Thanks for this, I couldn’t sleep last night, then gummied up too much and missed work and dr appt. Now time for escape reality with CRD.

sen

Been watching your old livestreams all day today, they’re calming for me. Thanks for all you do :)

Kerne

You had me laughing in the first two minutes. Thanks so much for that! Also seeing you make good use of the new space is awesome.

I've vaguely heard of IP-TV over the years as something some DLNA servers could do, but generally in an *cough* illegal context. But I guess it's a thing that cable companies are also doing now that they need to bundle "cable TV" with their fiber internet packages. I mean, "need" is a bit strong, but you know, upsellers gonna upsell. For comparing speakers, it might be useful to play the same audio out of actually known-good ones, just so the effects of the microphone setup aren't blamed. I mean, if speakers are actually a modestly important part of the product, which is not the case here. I mean, this is like the onboard speakers that projector manufacturers keep stuffing into their products for god knows why.

When the world (or the US) needed him most. Thx Gravis hope you and everyone else is holding up ❤️

salem

us presidential election went poorly : (

Wired remotes are common in situations where you will have multiple devices of the same model in the same installation. It's for exactly the kind of situation you describe with playing "lights out" with a video wall and the power button.

cathoderaydude

Ah okay, That makes sense, surprised I didn't make the connection. Weird that NEC doesn't actually list any for sale though

Scott Kemp

I needed this. Thank you.

Sean Miller

Just understand while I respect that you have a different opinion, acting as though life is over is just silly. Life will go on just like it did for the Rs 4 years ago.

We had 3 NEC projectors making a big wall of projection in a NOC I once worked in, and the projectors and remotes both had 3.5mm jacks on them. You’d just connect a regular cable between and they’d switch from IR to wired and IIRC wouldn’t need batteries then either. It seemed like a neat idea.

Chas Becht

I once had to do some on-site development work for a cable television operator. The lab had a bunch of set top boxes and remotes with little pieces of paper taped around the IR modules to try to make them semi-directional. Everyone was told to try to hold the remotes close and wrap your hands around them to avoid accidentally controlling your neighbor's box. I had a machine set up doing a long duration soak test on the mini program guide (2-3 lines of EPG data in the bottom third under a live TV preview) trying to diagnose a memory leak. A group came in to demo the current state of the software to some executives. They were of course immune to the normal courtesy directives and stood back navigating through all the menus and features and such while also sending spurious cursor movement commands to my box. Since most menus are vertical lists and you start at the first item, the most common button press was the cursor down arrow. On the program guide, that means going down the guide to higher numbered channels. Eventually, due to Fitts' Law they tuned to the highest numbered channel in the guide. The highest numbered channels in cable systems are generally reserved for paid adult content. The development boxes of course had their accounts subscribed to all premium paid content so we could test every channel. I quietly reached over and turned off the TV connected to my box. I wish those boxes had wired remotes.

Chas Becht

@sen I've got a rack mount Sony cd player with the same kind of wired remote setup. Never tried to see if the remote could run without batteries in wired mode. (Side note: Try to find another 1U rack mount cd player. I dare you.) (Edit: Nevermind. I just googled and you can just buy them now. They used to be like hen's teeth. )

I used to set up tile matrix setups at a previous job using slightly newer versions of these NEC monitors, they used DisplayPort daisy chaining and had multiple ethernet ports for daisy chaining the ethernet as well. We'd configure a unique IP on each one and then using a laptop and their color calibration software we could hold a calibrator on each screen and the program would cycle each monitor through the calibration process to measure their brightness and other capabilities and balance all the monitors to closest matching values. We also used NEC's OPS cards which did 4k on their DisplayPort (the internal connector was only 1080). We'd feed that 4k image into the first monitor with a DisplayPort cable and then down the rest of the chain.

Sean Miller

The best thing I ever did is surround myself with friends from both sides of the political spectrum. All of us who vote have to pick a side, even though I wish it weren't that way. I love this country very much and served it for almost 8 years. It's important to me that everyone feel they have a say in what happens and voting is the tool to do that. The results are in, so let's hope the new admin will do a good job for all of us. If they don't, vote them out next time and try again.

Lily Finley

I don't think I've ever seen a device with both RS-232 and Ethernet control that didn't accept the RS-232 command set over telnet. So I would imagine it is indeed possible to do everything you can do over RS-232 over Ethernet as well (if only via telnet). I wouldn't be surprised if you could even daisy chain them via RS-232 and then control the whole chain over using a single Ethernet to the first display in the chain.

Hey! I used to work at a casino and was in charge of about 200 of these. Same model, inputs, settings, etc, but a variety of sizes. We used AMX video-over-ip boxes to send signals over the network to these. Those boxes also included a serial output that the installer foolishly did not connect to the displays. Anytime I got up and close with one, I connected the rs232 from the AMX box to the display, and it meant I could get into the menus and everything with a web-based interface I set up to use on an iPad. Many of the settings could be changed without even displaying a menu on-screen. I felt so cool getting that to work.

Taylor Kokinos

This is an extremely welcome distraction. Take care of yourself and yours.

Anthony B

I used to manage these exact TVs, and you're mostly right. If you built a video wall with them, you could connect the first one via Ethernet, and daisy chain the rest via the rs232, you could control all of them. However, I could only get the "video wall" type functions to work like this. I think it's because they anticipate that's the application you'll use this configuration for. That being said, it's entirely possible you could control all of them. I never got my hands on the proper full documentation.

XPEric

Thanks for the distraction! As a poll worker, we could see where this was going pretty early, so I had a head start on the disappointment. As a side note, having watched this video on a LG C3 OLED, I can confirm there is no option to disable interlacing in the settings.

Philippe

No IP TV? That’s a surprise, I thought that has become the way for most TV broadcasting … How does streaming of TV works in the US (outside Netflix and etc.)

EyeMWing

Rtsp mostly, within a confined environment. Over the wire from a broadcaster, its ATSC

Chickenbread

The PAL-60 thing I think could be referring to what's used in Brazil, as they use the PAL color standard, but at 480i60, rather then the European standard of 576i50... With that logic, the 4.43NTSC I imagine is the same thing, but with NTSC (aka 576i50 using NTSC, rather then PAL or SECAM)

Aidan Rayner

Come to think of it, I'm pretty sure my secondary school/sixth form (same place) had displays with OPS modules in them. I remember these large touch screen boards being in every classroom, and then one on each floor outside of the classrooms as like a breakout area, and *also* one at the ends of the floors as like a meeting space/lunch area. They all booted Windows 8.1 (natch, it was 2014/2015 then) but with a press of a button could switch to Android where you could doodle on the screen and such. I am almost certain they had those modules in the sides of them. They were actually really neat. The stands for them before they had them wall mounted though were **massive**.

Kris Asick

I'm always worried about latency when looking up new displays since manufacturers are terrible about indicating what the latency is like on their devices and it can vary wildly even within the same brand. What's the latency like on these panels?

Curtis Duncan

Bro just the sentence "that's two streams from the same computer" excited my nerd sense immediately. Imagine dual screening on one screen. How dorky is that!

Sammy B.

If you need more beefy display mounts, Chief is a professional display mount provider that makes many form factors that can do 200lbs

Thank you for injecting some sanity into the conversation. We can all take a lesson from the Republicans in handling an election that didn’t turn out in our favor. No one made accusations of voter fraud or rigging, no one even went to the Capitol for so much as a peaceful demonstration of their disappointment. Not a single one. Because it’s all the same, and no election in history has never had negative consequences for anyone ever, so people just need to grow up and stop acting like children. We’re all just voting on the specific wavelength of light that we find most visually appealing, that’s all.

this video is dangerous because I immediately checked facebook marketplace and found a 75 inch 4k NEC multisync for $350 and now it’s calling to me like the green goblin mask

Pierre

Now I want some 🤣

Rocko Rottie

Shit I should go look now...
