But why can't I buy an external webcam, where that isn't an issue, with the same quality as a smartphone camera?

Wouldn’t a smartphone work for you then ? it might need a mount to be properly positionned, but that would be the only IRL hurdle. On the software front I don’t know how good the current options are, but fixing bugs should be doable.

I tried going this route a few weeks ago. There's a few pretty big problems with current phone-based solutions:

- You need to fiddle with your phone (which is probably mounted to a monitor?) any time you want to turn on your webcam

- There's a perceptible lag on the final video, not ideal

- Phone needs an external power source, charging-over-USB usually isn't enough to power a phone with an always-on camera

- The phone will get hot, as it's not designed to run camera constantly

- For Android, your best option is to stream video over USB, which means enabling ADB and developer settings, which is inherently insecure. It also makes the charging problem above trickier, as phones usually only have the one port.

Honestly the best phone-based solution right now is to join the meeting twice - once on your personal phone for sending video, and once on your computer for sending/receiving audio/screenshares.

For me it's hard to believe that 4k on 27" is not enough, I use 1440p 27" 144Hz display as daily driver and barely see any pixels(usually with badly hinted fonts, and still not pixels, but uneven forms of letters), because I sit around one meter apart from it, and sitting closer makes me turn my head around too much, except when watching movies.

Yeah, same - 27" 1440p as a daily monitor for work and I have no issues with it. I have had a 27" 4K monitor for a while but it was just too small at 100% scaling, and at 150% scaling some things looked naff. Prefer the 1440p at that resolution.

That's what we say too. 27" 4K monitor is too small at 100% scaling, while too small at 50% scaling (pixel-doubling hi-dpi mode).

That's why the idea is to have a 5K at 50% scaling (so everything is pixel-doubled on each axis, and a pixel becomes 4 pixels, doubling the detail you see).

> But...that is 4K. It's what 4K is defined as, exactly 2x 1080p resolution in each dimension. That's irrelevant though, except if we're talking about consuming movies fullscreen. For a monitor I don't want 4K, I want insivible pixels at viewing distances, so hi-dpi. I would also prefer no scaling for assets that are bitmap in nature. This ideally means pixel doubling (less cpu/gpu demanding and less fuzzy than fract…

> That's irrelevant Not to the upthread specific claim that the resolution was “not quite 4K”, which is what the comment you are responding to addressed. On the bigger issue, I don't really see the complaint. I have pretty good vision (corrected—to 20/15 or so—uncorrected is crap but I'm not coding without glasses/contacts) and honestly my 34” ultrawide at 3440x1440 is excellent for coding, and pretty much any other…

>Sure, more pixels are always better. But does the sub-4K display look like crap or force bad sizes for controls? No.

Sure, I can work with a 3440x1440 34". Heck, I've worked with CGA monitors back in the day, and black and white (!) SUN Sparkstation monitors.

But, as you said, it's about looking better. "Doesn't look like crap" is a pretty low bar, no? For 2020, and after 10 years of hi-dpi phones and laptops, I expected better from monitor companies...

I am from Warsaw, Poland and believe it or not, Warsaw is about 7 degrees north from northernmost part of Vermont. Vermont spans 42 to 45 degrees while Warsaw is at 52 degrees. Did you know that most of people in Canada live at the lattitude of Croatia or south of it?

I lived in .be for 3 years. I believe it :-) I think my favorite tidbit is that Rome and Boston are at the same latitude.

Also, New York city and Naples, or Washington DC and Cairo.

> The IEC 60320 connectors were specified for exactly that reason. Honestly, I don't get why these were not made mandatory for all kinds of appliances. There are even locking variants available if vibration is of concern. I'm not sure what you mean by the second sentence but you can't use most appliances made for Europe in America and vice versa. Most electronic appliances depend on the input voltage and supplying 24…

This just seems so crazy, to think of 120V. I haven't seen a house here with 120V in my entire lifetime. It sounds like a relic from the past, like the kind of thing people used back when they rode horses.

Hmm, I'm having trouble understanding what you mean. 120V is the standard household plug in North America. If you're in, say Europe, I don't imagine you'd see a house with 120V as IIRC, 220V is the standard, and you generally have to connect to your local grid. I think the parent's post about 120V was about international devices that may have to work in North America, for instance.

It always baffles me that high-end webcams also usually come with bad microphones built-in. If you're dropping $200+ on a fancy high-end webcam for either streaming or high-quality video calls, you're probably also going to be dropping $60+ on a decent stand-alone microphone.

> The lazy conglomerates who sell these peripherals often don’t actually produce the parts in them. You think that complete vertical integration will improve product quality?

Apple

Apple is quality in terms of UX and marketing.

The qualities I value however are freedom, security, and privacy.

In that lens, the quality of Apple is very poor.

> not-quite-4K 3,840 x 2,160 But...that is 4K. It's what 4K is defined as, exactly 2x 1080p resolution in each dimension. > Windows scaling looks like crap I don't understand. 2x each dimension (so 1 pixel in the old resolution is 4 in the new) is, like, the easiest possible scenario when it comes to scaling in software.

That's UHD. 4K is defined as 4096px wide. But I guess the mass adoption of the term 4K in consumer electronics changed the definition.

That's DCI 4K.

Two groups have competing definitions. One isn't inherently correct.

I say this as someone who was "that guy" when it came to HD Radio: "It's not High Definition, it's Hybrid Digital!" even though that's exactly the confusion they were trying to encourage.

Arguing that this is misleading is a fool's errand, and only plays into things if you assume that the primary purpose of a "4K" screen somehow is inherently "to play back cinematic content", which... it's not.

A camera off a $50 budget phone will probably beat every $100 webcam on the market. So why can't I get that same camera module, minus the phone parts but plus a usb interface, for $100.

What's one such phone? I've never seen a <$300 Moto phone match a $100 Logitech webcam.

Can't say I did a ton of research to find such a phone but based on my experience in the past it certainly doable.

There is one for $70 on amazon that might be a contender. I'm sure if I searched aliexpress or something I could find something better for even cheaper.
