It was set to Off, so I moved the slider back and forth to play with that and then turned it back to "off." The image was currently the stretched 16:9 with letterboxing at top and bottom. One thing setting I hadn't touched when connecting the MacBook Air to the projector via HDMI was the Underscan setting in System Preferences > Display. Ok, I believe I've solved ONE of the TWO issues.
WHY IS THIS SO HARD?Īs seen from the screenshots, mirror mode, but that shouldn't have anything to do with the aspect ratio issue.

But does ANYONE (pretty please?) have any thoughts before I buy something else?Īll I really want to do is screen mirror my MacBook Air with the Apple TV in full-screen 16:10, which is the native aspect ratio of the 13" MacBook Air. The only other thing I can think of trying is an HDMI-VGA cable. the default 60Hz) didn't change anything.

I thought the Blu-ray player result indicated that maybe I just needed to change the output frequency of the Apple TV (though the projector never displayed this error message when connected to it), but even changing the resolution to 1080p 24Hz (vs.

MacBook Air > Thunderbolt-HDMI adapter > HDMI-VGA adapter > VGA cable > projector: displays correctly as 16:10 full screenīlu-ray player > HDMI-VGA adapter > VGA cable > projector: acts like it's trying to connect, but displays message: "Not supported H: 67.33 kHz V: 59.84 Hz" Here are the signal chains I tested (results in red):Īpple TV > HDMI-VGA adapter > VGA cable > projector: no video signal detected I checked the HDMI-to-VGA adapter by using it with the MacBook Air, and it works, so I know the adapter isn't bad. So I ordered an HDMI-to-VGA adapter (male HDMI to female VGA) to see if screen mirroring would work in 16:10 fullscreen if I used the VGA cable.īut to my surprise, the Apple TV will not output ANY video AT ALL with this setup. So to recap, my issue is that I can't get my MacBook Air to display in 16:10 FULL SCREEN (NOT letterboxed) with my Epson projector either through HDMI or Apple TV Screen Mirroring. USING HDMI ("optimized for built-in display") - letterboxed all around USING HDMI ("optimized for projector") - letterboxed on top and bottom I'm also having similar issues mirroring the screen using the Apple TV, but I'll leave those details out for now to avoid information overload.
I marked the corners of the "screen" in red so you can more easily see the letterboxing. So what gives? Is it not possible to fill a 16:10 projected image of a 16:10 MacBook Air using HDMI? See pictures below I took using a projector at home that is also 1280x800. the default setting of optimized for the Epson PJ), the projected image becomes 16:10 but is letterboxed now on all 4 sides. If I go to System Preferences > Displays and select to optimize the settings for the Built-in Display (vs. No matter what options I select on either the projector or the MacBook Air, I can't seem to make the darn image display at a full-screen 16:10 aspect ratio.
However, when I connect the MacBook Air to the HDMI cable with a HDMI-to-Thunderbolt adapter, the projected image is 16:9, and thus is stretched and letterboxed at the top and bottom. I've routed this cable to a much more convenient access point than the wall-mounted VGA port, so I'd prefer to simply use it as my primary connection to connect the projector to either the Apple TV or the MacBook Air using an HDMI switch. I've recently added an HDMI cable to the setup to be able to use an Apple TV with the projector as well. Using the VGA connection, the image fills the screen perfectly, which of course makes sense since both the computer and projector have the same aspect ratio. The projector has a native resolution of 1280x800 (16:10) and my MacBook Air has a native resolution of 1440x900 (16:10).
If your adapter has a VGA port, you may be able to use this type of connection.For years, the only connection I've used to connect my MacBook Air to my Epson projector has been a VGA cable with a VGA-to-Thunderbolt adapter. For example, according to the Lenovo support site, your display also supports VGA. You might also check other types of connections. If there isn’t an HDMI port in your adapter you may need to purchase another adapter. We’d like to see if we can help.Īre you using the multipart adapter like the one we have linked above? If so, does it have an HDMI port in the middle like this one? We’re asking because there are different types of multiport adapters. We understand that you’re trying to use your new Lenovo display with your MacBook Air using your USB-C Digital AV Multiport Adapter, but the HDMI cable that came with the display isn’t working with your adapter. Thank you for posting in Apple Support Communities.
