does either airplay or chromecast allow 1080p? I have maxed out the 2 monitors on my mbp; I have a third monitor, and I can connect to it via airplay, but I only get 720p. Thus, is there an airplay, chromecast, or whatever else dongle that gets 1080p?

dpsutton01:02:35

my experience with chromecast is that it is too slow for mirroring

qqq01:02:49

😞 // I have a $25.00 "anycast" dongle that supports miracast/airplay, it's laggy, but tolerable for showing documentation unfortunately, it's only 720p

tbaldridge01:02:04

@qqq I have 3 monitors on my MBP. 2x thunderbolt->display port and 1x hdmi->dvi

qqq01:02:21

@tbaldridge: does this require special thunderbolt active display monitors? what I have is: (1) a mbp that supports itself + 2 external monitors (despite having 2 display ports + 1 hdmi) and (2) three hdmi-tvs

tbaldridge01:02:48

Nope, just a cable

qqq01:02:20

can you point me to the part on amazon? 🙂

tbaldridge01:02:37

I've run this setup on 2015 and 2013 mbp

tbaldridge01:02:45

Sure but I'm on my phone

qqq01:02:50

I have a 2015 mbp 15 retina

qqq01:02:52

what's the name of the part

qqq01:02:53

I'll look it up

qqq01:02:45

I have https://support.apple.com/kb/SP704?locale=en_US -- which according to docs, supports 2 external monitors + builtin lcd. If I use some magical thunderbolt cable, can I get it to support a third?

tbaldridge02:02:21

I think those specs are wrong

qqq02:02:03

what cables are you using for the displayport/thunderbolt?

tbaldridge02:02:12

the secret is that Display Port, HDMI, DVI and Thunderbolt all support the same video format, so cables can convert from one to the other.

qqq02:02:48

I have 2 displayport -> hdmi cables; and 1 hdmi -> hdmi cable now, I can use any two of the three monitors, but if I connect all 3, one is always blank

tbaldridge02:02:03

interesting....

qqq02:02:11

alright, let me order some new cables and see if that fixes it

tbaldridge02:02:22

well, wait a sec

qqq02:02:42

it's fine, you're not responsible if it doesn't work out 🙂

tbaldridge02:02:10

I wonder if DisplayPort is speciaal

qqq02:02:10

the annoying thing is that I can "get 3" by using: laptop, external, external if I could just do external, external, external(mirror of laptop) i'd be so happy

qqq02:02:21

there's something about "active cables" and http://apple.stackexchange.com/questions/111112/how-to-use-3-external-monitors-on-15-late-2013-macbook-pro-retina claiming that these monitors can only support 2 "passive"

qqq08:02:52

@ashnur: (re wikiquote question in #clojurescript) -- if you figure itout, please let me know; I've been trying to parse the wikipedia xml, and the only solution I've come across so far is: install mediawiki + load the db

Aron08:02:02

wow, that sounds scary 😄

Aron08:02:48

there are no nice tools, as i have to conclude again

qqq08:02:17

there's a number of adhoc xml parsers out there, which may work on wikiquotes (due ot simpler structure), but I never got any to work well on actual wikipedia xml

Aron08:02:41

there should be a universal ui for i/o that has modules for transmuting both the input and the output where the modules are platform specific optimizations

Aron08:02:55

i like to call this theoretical thing a "real browser"

Aron08:02:07

i am sick of the data mangling over and over again

qqq08:02:29

we need an executive order saying that all data must be stored in edn format

Aron08:02:33

yeah, wikipedia must be even harder, i imagine that

qqq08:02:11

yeah; I was rather unpleasantly surprised, I thought xml was verbose/messy enough; but apparently they figured out a way to roll their own adhoc, undocumented language on top of xml

Aron08:02:50

tbf i am not surprised at all, i expect nothing better from the same old idea of universality

Aron08:02:34

if something is good for everything, it's good for nothing, that's my motto. one of many 😛

Aron08:02:30

so, i think the order should be reversed, and your file should be explaining itself, or the file format should be specified in a way from which one could automatically deduce a parser. there is no universal file format.

qqq08:02:55

http://www.kiwix.org/downloads/ <-- wikiquote is there, though not sure if latest

qqq08:02:57

may be easier to parse

Aron08:02:31

freshness is not very relevant with quotes i think 😄

Aron08:02:15

although there is that very nice new one "the burden of the brutalized is not to comfort the bystander"

Aron08:02:21

i don't have a zim parser 🙂

stardiviner08:02:45

kiwix also have an Emacs extension for searching.

Aron08:02:57

oh, that's close to Mandelbrot level of deepness...

Aron08:02:22

think of human beings, not A.I. pls

Aron13:02:37

@qqq https://github.com/attardi/wikiextractor have you tried this? maybe it doesn't help, but i am going around trying everything now

Aron13:02:09

yeah, it's not as i hoped, for sure 😞

qqq20:02:47

@tbaldridge: it appears even after getting 2 "active" displayport -> hdmi converters, this particlar mbp only gives me 2 screens and just refuses to power a third external monitor

tbaldridge20:02:52

@qqq that stinks, must be something to do with the 2014 model. Kindof glad I never ran into that 😐

tbaldridge20:02:48

Well the other option is USB->DVI connectors, those appear as new display devices (cards), they're slow, and super crappy for video, but I've heard they work okay for code.

qqq20:02:54

@tbaldridge: this is expected given that the official apple webpage spec for my laptop says it only supports 2 ; but there were all these rumors on youtube/forums talking about "yeah, they mean only 2 passive; if you get active it works, blah blah blah" so I had to try 🙂

qqq21:02:11

any usb -> dvi you recommend? all the ones I find on amazon are windows only, while the osx ones are all < 3/5 stars

qqq21:02:22

I also got

qqq21:02:30

I also got airplay/miracast working, but that's only 720p, not 1080p

tbaldridge21:02:30

what are you air-playing to?

tbaldridge21:02:42

I'm pretty sure my AppleTVs all run at 1080p, although I've never tested

tbaldridge21:02:03

and no I've never used the USB->DVI stuff, just seen them in use a few places

qqq21:02:19

I have a sony bravia 55" 1920x1080 if I connect it via hdmi, I get 1920x1080 if I conenct it to my mbp via airplay, I get only 720p
