No. 720 is progressive. Every line in every frame is painted in every pass. In 1080i, it is interlaced. Only one field, every other line, is painted per pass.I presume you mean that a 720p signal has nearly twice the frame of a 480 signal, not 1080i. You are right as it is a bit higher, by 240 frames, about 1/2 more in reality. But it is a lot closer to 480 than going to 1080. As I mentioned by old Toshiba 480' EDTV CRT looks the best in SD, but not by that much via the Toshiba 720. I notice that some of the networks only broadcast in 720 at this point anyway, ABC, FOX, & MYTV. The rest are in 1080.
In theory, 720p, or almost any progressive image, is better for motion, such as sports. In reality, many other factors weigh in and can skew the results. That is why we’d love to see 1080p.
Now, flat screens do not actually skip a line of resolution each pass. That Rube Goldberg idea came about to compensate for the limitations of technology at the time. And CRTs made good use of persistence of vision.
The flat screen takes the interlaced signal and makes it progressive, with varying degrees of success.
I have had mixed results with Sony equipment I’ve bought in the past. So I was VERY careful in reviewing different brands and models. When it came down to it, the LG OLED was hands down the best. But OLED does not seem to be the panacea we all expected. It just hasn’t matured fast enough. And it certainly will have a shorter lifespan. It might never deliver the promised perfection at a low ink jet produced price. Other technologies are moving up fast.
Next was the Sony 900 series, not cheap, but way less than the LG OLED.
BTW, smaller screens just “appear” to have higher resolution.
