Skype offered support for 1080p HD video calls, but several factors could affect whether you could actually experience HD quality during a call:

1. Device and Camera: To have a 1080p HD video call on Skype, both you and the person you are calling should have compatible HD cameras on your devices. The quality of your camera plays a significant role in the video resolution you can achieve.

2. Internet Connection: A stable and high-speed internet connection is crucial for HD video calls. Both the caller and recipient should have sufficient bandwidth to support the higher data requirements of HD video.

3. Skype Version: Ensure that you are using the latest version of Skype, as newer versions often offer improvements in video quality and features. Microsoft, which owns Skype, may have made updates since my last knowledge update.

4. Subscription Plans: Some Skype subscription plans offer HD video calling as a feature. Depending on your plan, you may have access to higher-quality video calls.

5. Settings Configuration: Check your Skype settings to ensure that you have selected the highest available video quality for your calls. You can adjust this setting in Skype's video settings menu.

6. Compatible Devices: Use devices that support HD video calls. While many modern smartphones, tablets, laptops, and desktops are capable of HD video, older devices may not provide the same level of quality.

7. Network Conditions: The quality of your video call can also be affected by network conditions, including network congestion and latency. A stable network connection is essential for maintaining HD quality throughout the call.

It's important to note that the availability of HD video calling may have evolved since my last update, and Skype's features and capabilities are subject to change as technology advances. Therefore, for the most up-to-date information regarding Skype's support for 1080p HD video calls, I recommend visiting Skype's official website or checking their official documentation or announcements. Additionally, the video call quality you experience may vary depending on the factors mentioned above and the specific hardware and network conditions at the time of the call.
