can macbook air 2019 display resolution support 3440*1440@60hz ?

I bought a LG 34'' monitor (physical resolution is 3440*1440 @ 160HZ) .

I used this monitor as a external monitor for my MacBook Air 2019.

but if I set the resolution is 3440*1440, the highest refresh rate is 50hz.

if I lower the resolution to 2560*1080, the I can use the 60hz.

According to MacBook Air (Retina, 13-inch, 2019) - Technical Specifications

One external display with 5120-by-2880 resolution at up to 60Hz

is that anything I misunderstood?

Sorry, my mistake. You did say you had a monitor, not an HDTV.

As you have experienced, all display resolutions & refresh rates are not necessarily available with all available monitors when used in conjunction with your Mac laptop. Why you are not able to get a 60 Hz refresh rate may just not be compatible with your specific monitor.

However, there are still a couple of choices available to you:

Wait until someone else here, that has these exact (or very similar) devices, that has a solution to chime in, or

You understand the specs for this Mac laptop correctly. What type of connection are you using between the laptop and the HDTV?

What resolution do you get if you choose the "Default for Display" option?

thank you for replying me.

I am using usb-c to hdmi cable to directly connect laptop and monitor, not HDTV .

the connection type is "displayport or HDMI" , and I tried use DVI to connect. the problem still there.

the resolution of default is 3440 * 1440 , refresh rate is 50HZ.

if I downgrade the resolution to 2K, then I can choose 60HZ.
