Connect two monitors using DVI and/or VGA to USB-C
I have a new MacBook Pro 15'' and want to connect two older 1080p monitors. Each monitor has a VGA and a DVI port. Is it possible to connect both to a single USB-C port of the MacBook? If so, how do people do this?

External Monitor not working on MacBook Pro 2015 with HDMI-VGA converter

I have an HDMI to VGA connector and a Samsung LED screen. The screen is fine, the VGA cable is fine, the connector is fine (tried with different laptops running Ubuntu and Windows).
**The Problem**:
I'm plugging the HDMI-VGA connector in my Macbook Pro 2015 but the display doesn't show on the external screen.
What I've tried:
I went in Displays and tried all given options like extend screen and more. The window also shows the name of the screen "SMB2230" on my Macbook and when I plug-in the HDMI, the screen flickers for a second and dock (on the right) disappears from the built-in display and I can move my mouse to the right and it also disappears but the external monitor shows the message "Check signal cable". I have tried restarting it as well but no luck.
**Note**: The screen is working with other laptops running Windows and Ubuntu with the same connector and the same VGA cable.
*Please don't tell me that I have to use MiniDisplay port/wire from Apple.*

I have this issue sometimes when my mac is waking up from sleep. Some applications like Google Chrome
A part or whole of the application is turning into a noise picture and until I restart the system, it won't fix.
In this screenshot I have opened inspect view of google chrome. In some websites, one part or whole of the website also, is being displayed like this.
I've updated to the latest version of Mac (Catalina 10.15.7) and chrome (86.0.4240.183 (Official Build) (x86_64)). Also this issue is happening when I use the main display or external display too. No differences.

MacBook Air 2020 - Unable to Connect to External Monitor
I have a Dell monitor which supports VGA - so I am using a VGA cable, VGA to HDMI adapter, and the USB-C Digital AV Multiport Adapter (Apple) to connect to my MacBook Air 2020 (running macOS Catalina Version 10.15.5). However, the screen on my MacBook keeps flickering - in the Displays window (under...
I have a Dell monitor which supports VGA - so I am using a VGA cable, VGA to HDMI adapter, and the USB-C Digital AV Multiport Adapter (Apple) to connect to my MacBook Air 2020 (running macOS Catalina Version 10.15.5).
However, the screen on my MacBook keeps flickering - in the Displays window (under System Preferences) I can see it detects the monitor and then loses connection very quickly.
I tried the same setup with an older MacBook Air 2015 (running macOS Catalina 10.15.4) - the only difference was that I did not need a USB-C Digital AV Multiport Adapter, instead I used a HDMI to Mini DP adapter. And it worked like a charm!
Is there any reason the newer MacBook Air would cause a problem?
P.S - to troubleshoot this better, I connected the MacBook Air 2020 with a monitor that supports HDMI with the Multiport Adapter and an HDMI cable - and it worked smoothly without any flickering.

Thunderbolt 2 to HDMI to VGA not detected, Thunderbolt 2&3 to HDMI to DVI-D (dual-link) black display
I had a temporary windows laptop that used an HDMI connector so I bought converters that one way or another got to HDMI, and I plan on getting two HDMI connected monitors when the right time comes (more RAM vs new monitor decision).

I had a temporary windows laptop that used an HDMI connector so I bought converters that one way or another got to HDMI, and I plan on getting two HDMI connected monitors when the right time comes (more RAM vs new monitor decision).
I currently have a 2015 Macbook Air 11" and a 2020 Macbook Pro 13". Both detect a monitor and let me move the mouse to the secondary display but show a black screen when connecting via Thunderbolt 2/3 to an HDMI cable and then to DVI-D (dual-link). The Air also doesn't detect any monitor when connecting it through thunderbolt 2 to HDMI then to a VGA cable, which the Pro is fine with. Any ideas on either situation?

Or do we have to connect to the Mini Display port.

I have a dell external display connected to my mb pro 2017 (Mojave), but whenever i try to sleep my mac (with sleep command), it goes to endless loop trying to sleep and then immediately wakes up, because external display won't sleep. Is there any workarounds / apps to prevent this behavior?

I can't connect the two monitors at the same time. When I do it, only the HDMI works. If I plug it out from the multiport, the VGA monitor shows up.
What could be the reason for this behaviour? How do I resolve this issue?

Connecting a VGA monitor via Thunderbolt to a MacBook Pro
I have a MacBook Pro 13.3" with OSX 10.8.4, which I use mostly at home and at workplace to connect to external monitor. At home, I have monitor with HDMI input and at my workplace with VGA input.

I have a MacBook Pro 13.3" with OSX 10.8.4, which I use mostly at home and at workplace to connect to external monitor.
At home, I have monitor with HDMI input and at my workplace with VGA input. I'm using a Thunderbolt MiniDisplay port to VGA and a Thunderbolt MiniDisplay port to HDMI cable convertors.
When I connect the monitor with the HDMI input at home it works perfectly and it connects quickly; that doesn't happen with the VGA monitor. When I connect it, the MacBook detects the monitor, but the monitor is not showing anything and goes to sleep mode.
Sometimes opening and closing my laptop helps, but not always.
After restarting the MacBook, I'm able to connect.
It's not comfortable to always restart the laptop, since I mostly leave it in sleep mode without closing applications. Does anyone have the same problem and found other solutions to this problem? How should I connect a VGA monitor without restarting the MacBook?

Mini Thunderbolt to VGA not showing video on external monitor but Mac says it is
The external monitor used to be working before, but now, there's no video being sent. The monitor is sleeping when I connect, even though the mac says it's connected. I am using a SyncMaster390b as the monitor. I tried turning it on and off and reconnecting everything, but still no luck. Any help?

The issue does not occur when booting in safe mode.
I tried resetting NVRAM and SMC.
Any suggestions?

I have a monitor (LG flatron W2353S 24 inches), a Macbook Pro (Late 2011) Model A1278, and a VGA displayport adapter.
The issue is that when I connect my MacBook to my monitor it detects the monitor as a 47" TV.
The cable works and I can use my 1920x1080 native resolution, but it displays wrong. There's a black large line on the left (like 2 centimeters) and on the right you can see that it's missing a part of the screen.
I think it's a driver issue or maybe the monitor is not compatible with this? This monitor only has a VGA port.
Any anyone suggest other things I can try?

I am using a MBP 13" late 2016 without touchbar. I use a CableMatters USB-C dongle to connect a VGA monitor to my laptop and it works.
However, when I connect an external projector to my MBP (I tested on two different projectors) using the same dongle
- there is a black screen on the laptop
- then in a few seconds, it says there is a problem in different languages and press any key to restart
Is there a problem with the dongle or the laptop? I am confused as the dongle works fine with a standard VGA monitor.

But if I connect both an HDMI and a VGA (via Thunderbolt adapter) to the Acer, I'm then able to toggle between inputs, and the HDMI input works fine. Problem is, now I have a useless Thunderbolt cable taking up one of my inputs. Any ideas?
