With only minor hiccups and idiosyncrasies, my ~$2500 M1 MBP has been a wonderful powerhouse to use - until last Sunday. As I'm the computer nerd of the family, I had the job of putting together a slideshow to run continuously at my mom's 80th birthday party. This was a pretty big to-do (about 100 people) so we got a room at a reception hall near her house, which featured a ceiling mounted projector and giant screen.

I called the reception hall and asked about the tech; they assured me their system can accommodate any standard video output, including HDMI. "Perfect!" I thought, as my MBP has an HDMI port. I've had no problems sending a signal to a new big screen TV, a 10+ year old TV, and computer monitors that had HDMI ports, so I happily checked that off my list.

I curated, edited, and assembled a boatload of pictures featuring her, and put together one of my signature "pro level" ;) slideshows to run in Photos. Just for the heck of it, I copied all the photo files to a flash drive; I don't even know why I decided to do that. Maybe in case Photos mysteriously borked on the day of the party - I don't know. Anyway, we got to the hall in plenty of time to set up. The manager pointed me to the cables running to the projector. Coming out of the wall was an ethernet cable, which ran into a powered converter box that accepted VGA, with a splitter for I think DVI and something else; I didn't see what. But running from the VGA port was a VGA to HDMI cable. Ok, looks a little sketchy but obviously it works, and the manager had no concerns as it "works every time I'm here."

First odd thing I noticed when I plugged in via HDMI was that when I clicked the "Displays" button in "System Preferences," it recognized the projector (I forget what it called it) but the second display icon was hidden behind the main display in that Preferences window, and I couldn't move it out. I couldn't change any of the settings that would help either. The second odd thing was: no output from the projector. Well, it was a blue screen, but it wasn't mirroring the laptop. I wasn't too worried, as I figured there would be some minor hiccup ("It just works! Eventually.") and I would need to tweak settings to get it right. Now I've done this plenty of times with older Macs and I can handle it. Well after at least 30 min of fiddling around in preferences and with the projector settings, I started to sweat; I wasn't handling it. This was my big contribution to the party and there is no way it's not going to work. I got the manager involved, and he got his "tech guy" involved and no one could get this running. I had a bunch of oddball cables and connectors with me, so I swapped out what I could, all to no avail. Ok, now it's getting close to go-time, and I've got no idea what to do. Early arrivers are starting to show up. This is a surprise party, so my parents will be the last to arrive, but I have precious little time. In a desperation move, I jump in the car and race up to the local Best Buy, thankfully only a few miles away, and buy:

  • $26 USB C to ethernet converter
  • $80 USB C 8-in-1 hub, with HDMI and ethernet
  • $110 USB C to every-port-known-to-man-plus-a-couple-new-ones hub with VGA, HDMI, and ethernet
  • $329 Lenovo Flex 3I 15 Chromebook (on sale; I see it's $429 now.)
No, I'm not f***ing around. This slideshow is going to happen, come hell or high water.

While this is all going on, I'm also calling everyone I can to see who has a PC laptop or Chromebook that they can bring. Thanks in no small part to me, most of my family and even some friends have converted to Apple, so no PCs available.

Hey good job, me. And you're welcome, Tim.

So I have to make something work here. Assuming the problem was in the conversion somewhere, I minimized the connections and tried the ethernet to USB C converter. Didn't work. I then tried the 8-in-1 converter. Also didn't work, in any capacity. Ok, now I opened up the big "triple display" hub and tried VGA, ethernet, HDMI. Aaaaaaaand...... nada. None of this stuff helped. My last - expensive - option was to open up the Chromebook which I would likely never need again. But, this is my mother's 80th bday, for God's sake. We're going to have a slideshow going back to 1943, no matter what. In the midst of all my attempts, my sister - who had my mom convinced they were going out for a quiet brunch together - calls and says she found this old, chintzy, maybe 12" HP laptop at my parents' house, but it had been unused in no one knows how long, and it wasn't charged.

"Bring it anyway."

I held off opening the Lenovo. So immediately after the big "SURPRISE!" as they all walked in, my sister handed off the "computer." She wasn't kidding about chintzy. It was built like a toy you'd get in a Happy Meal: All plastic, ugly, and flimsy. But desperate times call for desperate measures. I plugged it in to the wall, hit the power button... and prayed. The ultra lo-res screen lit up. In my adrenaline-fueled panic, I didn't notice what the OS was, but it seemed to be something after Win95. I didn't care. All I knew is that it had a VGA port. I swapped the VGA to HDMI cable for a VGA to VGA, plugged it in and closed my eyes.

"It works! It works!" I heard my cousin say as the comically primitive giant icons appeared on the ~20 ft. screen. I then stuck the USB A / USB C thumb drive into the lil HP's USB 2.0 port and watched the icon pop up. Of course unlike apple, Win media player or whatever has a slideshow function built in, so I just clicked "Play" and made my way to the bar, never looking at the screen again, but listening to the laughs, comments, and other sounds of delight as the crowd enjoyed the pictures. Of course, I basked in all that for about 3 minutes, until my dad whispered to me that he had suddenly caught a case of laryngitis, and that I would have to say a prayer, make a speech, and give the toast. All off the cuff, of course. Hey, what's a little more panic-induced stress among family?

Lucky for me, I never actually opened the Lenovo, so that was easy to return. (Although to be honest, I was kind of looking forward to having a new piece of tech around the house to play with. I couldn't return it in good conscience if I had actually used it successfully.) The other opened items needed some explanation, but the good people of BB did agree to refund everything.

So, cheers to you, crappy little HP. You saved the day.

And Tim? I'm so glad I could help contribute to your bonuses. Also, you and your precious, elegant MBP can **** right off.

RANT OVER.

How do you know a more recent Windows PC wouldn't have the same issue? I bet you that old laptop didn't have Windows 11 on it. Did it even have Windows 10, or 8?! How old was it?

Older tech works with older tech. This is why I am not a fan of HDMI. Same port/cable has been used for decades, but you need to make sure you have correct versions in the cables and ports! Projectors are far worse than any old TV that might have worked.

Have you tried this? I know - holding option key to invoke hidden menu is not intuitive but it is what it is.


Do you see the right image right away? You can start with your presentation right away. Don't see an image? Follow these steps:
  1. Click the Apple logo at the top left of your screen.
  2. Click System preferences and got to Displays.
  3. Press and hold the Option key on your keyboard and click Find monitors at the bottom right of your screen.
Next, you can choose to extend or duplicate the screen. Check or uncheck Enable synchronized display.
Does this window not appear? Check how many monitors you can connect to your Mac.
  1. Click the Apple logo in the top left of your screen.
  2. Click About this Mac.
  3. Click the tab Sources and click Specifications. This will open a webpage. Under the header ''Video support' or 'Graphic support and display sources', you'll see the number of monitors you can connect to your Mac.

This should have been the cue to head to BB and pick up a projector or a 65" LCD and a stand.

That ethernet > VGA conversion may be the part that hinders the image being displayed.

For one it may require the HDMI port with enough power, I know the MBP's built-in HDMI ports are already "active" but it may not meet the power needed.

For two, it may be HDCP (DRM) related. That VGA chain may be expecting a DRM-free signal while the MBP and your dongles' HDMI ports all have it.

Either way, there is a reason some people still lug around utility laptops with all "legacy" ports that you can name, because this **** needs to work all the time, but you cannot line up what's available in the environment.

Chances are that HDCP was not supported by the venue's equipment, and the multiple conversions in the path likely meant the Mac couldn't properly recognize what it was connected to. That's not really a fault on Apple's behalf, but a matter of older equipment not supporting more recent standards. Even looking at some similar VGA-ethernet adapters available today, they all seem to list certain chipsets they do and do not work with, and there is no mention at all regarding DHCP support or even HDMI.

What is interesting is that the StarTech adapter specifically mentions that MacOS does not support VGA over Ethernet, but that (in theory) should only apply in cases where the Mac is directly connected to the adapter.

As *the* tech guy around here, I feel your pain. BTDT many times.

Mac's used to be great at handling odd monitor situations, but those days were over a few years ago and my go to machine in odd situations is always a Windows machine now. (usually a Lenovo!)

Thanks. I really just wanted to blow off some hysterical steam (hence the term “rant”), and maybe rustle up a couple of laughs at my expense - knowing full well I’d likely get Monday Morning Quarterbacked.

This should have been the cue to head to BB and pick up a projector or a 65" LCD and a stand.

Or much cheaper Chromebook.

Or better yet (as someone noted), not assume my fancy new MBP is the best tool for the job, and bring the functioning old MBP and old PC laptop I had sitting at home.

🤦‍♂️​

This one I sympathise with.

So I'm in the middle of doing a mathematics degree and we needed to use Maxima. Can I get it to work on my M1 MacBook Pro? Hell no. So nicked my daughter's Lenovo T14 gen 3 running windows 10. Works perfectly.

Now writing this on a shiny new Lenovo T14 gen 3 that cost me less than a new M1 MBA...

I have opened a couple of threads about bailing out. Sometimes worse is better. Every day it feels more true.

Just a note - if something is that important, I would consider it best to do at least one rehearsal at least one day beforehand. There are too many unknown variables if it’s a venue that I haven’t used before / unfamiliar with. Just my take on the issue at a high level, tech stuff notwithstanding.

Been there. Stress of the moment, high importance event, enter with Plan A and a ton of confidence, then when it all goes pear shaped run through a tech store buying plans B, C, D and E, then while waiting to pay seeing something that's probably more like plan L but it's within arms reach and stress reduces my impulse control.

Good job pulling it off. The only thing that feels better than a job well done is a job well done that needed to be salvaged by pure adrenaline. Thanks for sharing!

Honestly, I skimmed over most of this without reading the entire novel, but know that I do pro A/V for a living.

Apple computers are rock solid on most things and are the standard for video as professional AV media players with programs such as PVP and PlayBackPro. HOWEVER, and I can pretty much guarantee that this was your issue, Apple outputs displays at 60p not 59.94. Most video projectors can handle this, but some can't. Also, many video switchers or other devices will not work at 60p. Furthermore, some video projectors are OK at 60p but the HDMI converter or splitter isn't. In short, 60p is nice for monitors, but it's not a broadcast standard. 59.94 is.

Interestingly, Windows outputs at 59.94.

Yes, I too found this out the hard way, but I have a road case full of scalers so it didn't ruin my show.


Your solution is a BlackMagic UpDownCross $159. A Decimator also works but costs far more.

Also interestingly, the oh so awful M1 MBP also outputs 59.94. It's in the display settings.

I know the problem and I know the HDMI->Ethernet box you are speaking of, because I had the same issue at a venue I sometimes worked at last year. I have the exact model name somewhere of this box. I came to the conclusion that this conversion box likely worked outside the HDMI standard, and as it was older than 2020 the manufacturer never tested compatibility with M1 Macs. In my opinion these venues need to fix their equipment, because these Ethernet-conversion HDMI ports will be absolutely unusable by any Mac user in the next couple years as Intel Macs are replaced by newer machines.

The need for presentations isn't going away and neither are the Macbooks, ultimately the venues need to fix their equipment.

I can pretty much guarantee that this was your issue, Apple outputs displays at 60p not 59.94. Most video projectors can handle this, but some can't.
It's actually the conversion box, at least the one I had the problem with, it worked connected directly to the projector.

If something is that important, I would consider it best to do at least one rehearsal at least one day beforehand.

Yeah, this.

Older tech works with older tech.

Also, this. That place needs to upgrade its tech; all this shouldn‘t be a problem the customer has to solve. It‘s them who „dropped the ball“, not the Macbook.

Technology changed fast, yet upgrading older video tech, like a projector, can cost upwards of $50K. As such, these items are typically upgraded after no fewer than 7 - 10 years. Smaller venues especially can’t afford that kind cash.

These aren’t small projectors for gramma’s birthday party, a cheap Christie projector and lens is around $30K. The issue is brightness. Professional protectors are expected to output a minimum of 7,000 lumens (7K) and the serious, installed units, typically have 10K or 12K. Add to that many systems, like Crestron, are more than just converters. These systems run off iPad like wall-mount tablets and have a media server in a rack. Upgrading those systems, even just the software, can be thousands and must be done by a certified installer. A new Crestron system can easily be over $20K.

I‘m sure all of this is true, but a projector without HDMI must be really, really old, no? Not 7-10, but more like 20 years old, I would guess.

M1 MBP has been a wonderful powerhouse to use
In case you are not aware, I want to bring this forum thread to your attention:

There is an adapter available with a bit of firmware hacking that can be used to enable additional video modes. Particularly useful if you want to use an HDR display such as an LG C2 OLED.
