I realized last night that my 1920x1200 display is scaling the Chromecast 1920x1080 signal to a full 1920x1200 resolution causing the entire display to be stretched vertically.

When hooking up the same display to my PC via the same HDMI port at 1920x1080 resolution, I get a 1:1 pixel mapping with black bars on the top and bottom of the image. Is there something in the image source that specifies whether to stretch or use a 1:1 pixel mapping? I went through all the settings on the monitor and nothing will give me the proper aspect ratio.

You sure your TV isn't set to Stretch as opposed to normal?

Have you double checked all scaling options of your display? This user contacted Google to let them know of the same problem:

1080p content scaled to 1920x1200 on a 16:10 aspect ratio monitor (other devices scale properly)

But was this bug ever fixed? Answer: No!

The other way around: If you have a 1920x1080 display and want to mirror the display of Android device wich has a 1920x1200 resolution, use this app the app "SecondScreen" (https://www.xda-developers.com/cast-...second-screen/) to set the resolution to 1920x1080 before casting to the Chromcast.

Its goal: "Second Screen aims at providing you with a way to properly cast your screen so that it looks is best whenever you are showing it off to your friends and family. It does so by allowing for a user selectable resolution and even DPI in order to take full advantage of your TV."

Chromecast2 on a HP 1920x1200 display

Please note I only tested this with the first gen Chromecast, so maybe this isn't an issue with the second gen units.

I tested the Chromecast2 on a HP 1920x1200 display. Pixels are mapped 1:1 with the right display settings. I don't have a Chromecast1 to check with this display.
