>>47029991
It's a shit University/Workplace

/thread

Because VGA does video but HDMI does video+audio.

It cuts down the number of cables you need to use by 50%.

Analog VGA was designed to CRT monitors. You need extra AD-DA steps and sync to display on TFT. Also, analog signals can collect noise so shielding/grounding is critical.

>>47030005
Basically all projectors in my school still use VGA.
Also you can't thread yourself.

>>47029908
digital > analog

>>47030034
its not like digital signals don't catch noise

Because with VGA the signal looks like vaseline covered shit unless I push the auto-adjust button every time but with HDMI it just werks

>>47029908
because HDCP

I don't know man, people are stupid.
I mean, dying from cold and eating raw meat worked perfectly for decades before this FIRE shit.

>>47030058
It's much easier for analog signals to catch noise, especially if they run close to power that is operating on a different frequency, it could introduce a ground loop. HDMI in particular has sync redundancies built in and sends an uncompressed video signal anyway so the quality point is completely moot. If anything VGA can not have quality on par with HDMI since they both originate from digital sources in the first place.

Analog inferior, digital stronk

Because my monitor looks like its driving down the street with those annoying moving lines.

Maybe in the future. The reality is you need to use hdmi or dp adapter to use with usb 3.1.

>>47030003
Yeah, and I've never gotten ground loop interference on an HDMI cord, can't say the same for VGA.

It was fine in the days of CRT monitors, but now that everything is digital, it only makes sense that the signal sent to the monitor would be purely digital as well. Otherwise, you'd be going from digital to analog back to digital again.

That said, I still use a CRT monitor as a secondary, so VGA still has its uses for me.

Because hdmi is proprietary and they have money to push their interests on people.

Because monitors didn't have DRM built in, and this was problematic for hollywood.

Also, Since we've mostly transitioned to LCDs, it makes sense to use a digital connection, to avoid an extra conversion.

But don't use HDMI crap.
Use the open display port.

If you really are an engineer kill yourself. How do you not understand the benefits of digital over analogue!? A digital signal does suffer from noise but it can be error corrected provided the digital signal is in some way redundant. An analogue signal gets displayed as is, so you see the noise if there is noise present. Digial signals may also have noise, but after the error correction has been applied to get a perfect signal. If there is so too much noise the signal will fail entirely giving you no pictures. In reality data is send in small packets and decoded packet by packet so when the decoding of a packet fail you get a faulty patch on your screen (eg when you satallite dish is blown in the wind).

The advantage is once you get a sigal with say less than 30% noise it can be corrected back to a perfect noiseless signal. That is why digital is fundamentally better than analogue although certain digital standards are poorly implemented (eg HDMI).

Displayport is royalty-free, which HDMI is not. Displayport doesn't have an obnoxiously huge connector, which DVI has.

Displayport can do tricks like connecting multiple monitors daisy-chained to one port. It also tends to support higher resolutions than HDMI, but only because devices are very slow to adopt the newer HDMI standards.

Pretty much, most businesses environments that don't need anything better (most don't) don't give a shit. Most college in the US still use it too. I work part time with my college and we deploy brand new projectors all over campus. We hook every laptop and desktop via VGA despite them having two HDMI channels presumably because VGA is cheaper (also the moron English teachers can't figure out how to pull them out and come bitching to us, unlike DP and HDMI) and there's no real need to give a shit for only 1080p monitors. They're real common too which is nice . Which is the same reason we still use Composite/RCA for all the DVD/VCRs.

hdmi has a few advantages;
- digital, while VGA signal quality can be very good, this is still better
- audio transport, no need for other cable(s) to transport audio, great for things like media centers and bluray players
- CEC, a communication system that allows hdmi devices to communicate, allowing things like controlling a media center by using the TV's remote (the TV can pass things like "play" to the media center through the hdmi cable), as well as power signals (perhaps you want your bluray player to turn on when your tv turns on, and off when the tv turns off, you can do that, too)

in many places VGA is still fine, and it even still has the advantage of longer cable lengths

There are many more advantages to HDMI over VGA.

HDMI cable runs can be infinitely long with repeaters, VGA suffers from ugly degradation the longer the cable run, not even mentioning the analogue interference most cables can suffer even at >3M lengths.

VGA maxes out at 2048×1536 @ 85Hz (but good luck finding a monitor that can display it)
HDMI 2.0 supports up to 4096×2160 @ 60Hz and is a continually evolving standard so that will only improve as the display technology improves.

VGA supports a maximum of 16 bits of colour resolution per pixel, HDMI supports 24 bits per pixel, with multiple colour profiles such as sRGB as well as 4:2:2 or 4:4:4 YCbCr.

HDMI is a much more compact and easy to use connector too, how many times have you flipped a VGA connector over a bunch of times blindly trying to connect it? And fucking screws to secure it? It's not even designed to be hotpluggable for fucks sake.

>>47029908
Back in 1995 we had analogue monitors which needed analogue signals. Our computers supplied digital signals; the VGA cards had to convert those to digital.

Now we have digital monitors. Sending them digital signals, and not converting d->a->d is the big idea.

I think it's more of a softcap than a hardcap because it's analog. Depending on length, interference, etc. you can probably go pretty high just that it would look really shitty. I've never tried it myself though.

If you can't figure out how to plug a cable into a computer you have no business operating one.

Take a shit, fuck the teachers. If they really need to connect, they will figure it out.

VGA adapters were created for old analog monitors. When you use VGA, you convert the computer signals to analog and then send it to your monitor. Your monitor then displays the signal as analog. Conversion means loss of quality.

On a HDMI plug, the computer output signal is send directly to the monitor where it displays digital output. There is no conversion. This results in higher quality.

VGA quality works fine for low resolution because quality of image isn't an issue on 800x600 screens. However on higher resolutions, quality degradation is seen.
