You're assuming a lot here. This might not even be an HTML page. It used to be fairly common in Windows UIs to have underlined blue clickable text in native applications.
Well, all I know it looks like an unstyled web page. We can just guess indeed.
Oh, and their display mode is set incorrectly. It's clearly non-native resolution (blurry text, bilinear "zooming" performed by the display, while individual pixels are in sharp focus) and wrong aspect ratio (the font appears too wide).
Perhaps 1024x768 on a display with 1920x1080 native resolution. Or something similar.
