Hi all,
I purchased a new mac mini and I'm hoping to connect it to a CRT monitor (HP CRT Monitor p1230). I need to use this monitor for research purposes. Previously I was able to get up to refresh rates of 160 hz. With the HDMI to VGA converter I have paired with the mac mini I'm limited to 75 hz. Anything I can do to get back to the 160 hz refresh rate?
Thanks!
Avi
Hello,
What kind of computer where you using with this CRT prior? Mac mini does not support high refresh rates over HDMI so a VGA display connected to an HDMI adapter would inherit the low refresh rate. Which model of Mac mini do you have? You most likely need to purchase a Thunderbolt to VGA adapter.
Hello,
Mac mini 2018’s Thunderbolt ports and USB-C ports are one in the same. You will need to either find a Thunderbolt 3.0 to VGA or use a Thunderbolt 3.0 to Thunderbolt 2.0 and then plug a Thunderbolt 2.0 to VGA adapter into it. Apple’s Thunderbolt ports are also compatible with Mini-DisplayPort so you can plug in a Mini-DisplayPort to VGA adapter into the Thunderbolt 3.0 to Thunderbolt 2.0 adapter.
Mac mini - Technical Specifications - Apple
"Four Thunderbolt 3 (USB-C) ports with support for:
DisplayPort
Thunderbolt (up to 40 Gbps)
USB 3.1 Gen 2 (up to 10 Gbps)
Thunderbolt 2, HDMI, DVI, and VGA supported using adapters (sold separately)"
There are lots of USB-C to VGA adapters, but since the Mac mini specs do not show support for any display over 60 Hz, they may not work for your display.
A Thunderbolt-3 to Thunderbolt adapter won't work with video adapters.
Maybe you can find a USB-C to VGA adapter that will support higher refresh rates.
both video card and monitor has to support a refresh rate
the fact that the crt does does not mean the mac can
Hi!
It's this model:
By thunderbolt port, do you mean thunderbolt 3 (looks like a USB-C port?).
Thanks!

Thanks! I'll give this a try.
USB isn't a display connection so I don't think a USB to VGA adapter exists. Am I out of luck?
Got it! Thanks for clarifying.
