The 28-inch 16:9 TV is 24.4" (62 cm) wide and 13.73" (34.9 cm) tall, while the 77-inch 16:9 TV is 67.11" (170.5 cm) wide and 37.75" (95.9 cm) tall. That makes the 77-inch 16:9 TV the larger screen by 656.3% of usable area.

The 28-inch 16:9 TV measures 24.4" (62 cm) wide by 13.73" (34.9 cm) tall, with a total screen area of 335 square inches. The 77-inch 16:9 TV measures 67.11" (170.5 cm) wide by 37.75" (95.9 cm) tall, covering 2533.5 square inches.

The practical difference: the 77-inch 16:9 TV is 175% wider, the 77-inch 16:9 TV is 175% taller, and 77-inch 16:9 TV offers 656.3% more screen area. Width affects how much desk space you need, while the height delta shows how much vertical space changes for documents, timelines, and video.

The practical choice depends on what feels limiting in your current setup. For desk distance, console use, video, and big-screen work, the wider option gives more room for side-by-side windows, while the taller option keeps more vertical content visible without pushing the edges of the screen as far away. If your desk is shallow, width and viewing distance matter as much as raw diagonal size.

At 3840x2160, the 28-inch 16:9 TV achieves 157 PPI. The 77-inch 16:9 TV at 3840x2160 reaches 57 PPI. The 28-inch 16:9 TV has 63.6% higher pixel density, resulting in sharper text and images.

For text-heavy work, PPI is the number that decides whether you are buying more room or just making everything bigger. A lower-PPI large screen can feel spacious for windows but softer for code and documents. A higher-PPI screen may need OS scaling, but it usually gives cleaner text and more flexible sizing.
