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 65-inch 16:9 TV achieves 68 PPI. The 77-inch 16:9 TV at 3840x2160 reaches 57 PPI. The 65-inch 16:9 TV has 15.6% 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.
