The Govee Dreamview TV Strip Lights are primarily designed for use with TVs as they can detect the colours on the screen and apply them to the lights. There is no specific information about them being directly compatible with a Windows PC screen. However, Govee does support software such as PC DreamView which could provide a similar experience, but this is not specifically documented for the H6198 models.

Definitively not it’s already a little to big for 55

The Govee Dreamview TV Strip Lights H6198 and the Govee DreamView T1 TV Light Strips, 55"-65" H61993D1-OF-EU, are actually the same product, but they were manufactured for different regional markets.

These are designed for TVs with 55-65". :)
