I recall when the first LCD TVs came out and I wanted to get a cheap 1080 one. The problem was that almost every TV said 1080 even if it was just 720 upscaled.
I put a uniform image in BMP on a memory stick - every column being R, then G, then B repeated. As the image was exactly 1080, viewing it in full-screen on a 1080 screen gave a sort of uniform grey color. On an upscaled monitor you could see very visible banding.
This would not have worked had the image been JPG.
For if it is still hugged to death

beautiful web design :) We aren't usually supposed to comment on it but im pretty sure thats exactly the reason this has been submitted.
It’s like a slice of the earlier web. Realized I haven’t seen a c|net logo around for a long time.
I'm not familiar with DisplayMate, and the site appears to be hugged. Unsure what this is doing on the front page, but for any similarly lost folks:
> DisplayMate is the Worldwide Leader in Video Diagnostics and the World's most advanced Display Calibration and Optimization Software.
I’ve always used lagom.nl/lcd-test/
A popular tool preceding the days of YouTube reviews, used for testing and reviewing displays.
Am I confused, or are these a bunch of JPGs on a CD? There's no hardware, right?
TLDR: Not JPGs, BMPs more likely.

This would also help to detect overscan. I remember when I was shopping for my first 1080p TV, many (most?) had overscan and no way to turn it off.
Website appears to be down.

Better call Web Dude
Definitely DONT call the Sales Guy!
Why is this on the front page? :)
Web design style nostalgia, I suppose.
