User reviews

UltraWideo is widely praised for enhancing video playback on ultrawide and widescreen monitors by removing black bars and automatically adjusting aspect ratios on platforms like YouTube and Twitch. Many users have used it for years with great satisfaction. However, recent updates have introduced performance problems such as stuttering, lag, and issues with fullscreen mode, leading to user frustration. Some users also face payment processing issues. Despite these problems, the extension remains highly regarded and recommended among ultrawide screen users for its core functionality.

Pros

Effectively removes black bars on ultrawide and widescreen monitors, enhancing video viewing experience.
Supports various platforms like YouTube, HBO, Twitch, and works well on different monitor aspect ratios including 16:9, 20:9, and 21:9.
Generally stable and reliable for users, with many mentioning consistent performance over years.
Automatically applies widescreen mode without manual selection, making it user-friendly.
Highly recommended and considered a 'must-have' extension for ultrawide screen users.

Cons

Recent updates caused playback stutter, lag, and performance issues, negatively affecting user experience.
The update removed the original black bars and replaced them with colored bars that some users dislike, with no option to revert.
Fullscreen mode functionality broke after update v3.4.1, failing to stretch videos correctly.
Payment issues encountered by some users, particularly PayPal payments being problematic depending on region.
Occasional video freezing/blocking reported after recent updates, possibly due to conflicts with other tools or Windows versions.

i use the free version on a regular 16:9 monitor to get rid of the black bars caused by all the different aspect ratios we get these days on youtube and other streaming platforms. it works great for me and i've been using it for quite some time. thank you and good job!

Why did u give us an ambient light and then take it back? even if it is a paid feature you shouldn't just give it and take it back. that's disappointing.

Wanted to pay-in but the payments wouldn't work via PayPal, will probably try again later in the year. Likely because I am in India and the geopolitical climate surrounding payment systems has impacted consumers. Thanks for your efforts.
