something akin to the 240p test suite, with grid, SMPTE, PLUGE, grey ramp, linearity, scrolling
a "480i test suite" if you will, would be super convenient with a portable DVD player for field testing displays
Is there a DVD based display test suite?

Re: Is there a DVD based display test suite?
there have been a few commercial ones, like Avia or Video Essentials or the Burosch AVEC one. The HCFR project had a free one for download. And of course there were HD iterations of the same projects on BD. Since you can set any BD player to output in SD just as well, it might make more sense to grab a HD one (except maybe for the 4:3 <> 16:9 issue). I also remember that several home theater tech magazines came with free calibration DVDs back in the days.
When I started getting into home cinema maybe 15 years ago or so I liked the Avia disc. Came with three color filters for "eyeballing" color saturation. Neat little disc.
But then again, if you ask me: a raspberry pi with some emus, some 240p test suite roms and an analogue video breakout adapter (or pcb shield) - anything from the RGB-Pi scart cable to the Retrotink boards with composite, s-video, component or RGB is certainly easier to handle than a portable DVD player. And if you really only need composite, the ealier Pi boards had this out of the box, right ?

I know the Pi Zero's do (think full-size as well), and besides a couple lines of code in the startup file, all you had to do was solder in the two wires - super easy. I made a post about my little home made tester with a Composite cable attached which I loaded up the SNES 240p test suite onto. I unfortunately fried it when I was using my pro-strength degausser on a PVM CRT monitor it was hooked up to (still have NO clue how that could happen...but it did lolFudoh wrote:And if you really only need composite, the ealier Pi boards had this out of the box, right ?

It was also great because I commonly rushed out from work to checkout a monitor and I could leave it in my car with one of those little USB battery packs and have a testing setup with me at all times (sure beats bringing a complete SNES setup with a 240p test cartridge - which is another good way to do it since that can do Composite, S-Video, and RGBS with only the appropriate cables needed).

I second the recommendation for Avia and Video Essentials. They're also handy today to test how well Blu-ray players or HDTVs upscale 480i.
(I would go for just plain Video Essentials on DVD, rather than the later Digital Video Essentials. DVE had a horribly confusing menu system.)

do those have an quick and easy menu to choose individual tests like 240p does? or is it some frustrating handheld process?copy wrote:I second the recommendation for Avia and Video Essentials. They're also handy today to test how well Blu-ray players or HDTVs upscale 480i.

Re: Is there a DVD based display test suite?
Avia is pretty nice with a LONG tutorial up front and all the patterns following that. I had Video Essentials on laserdisc, but probably only DVE on DVD.
The only MINOR problem is you usually can't pause the patterns to perform your checks, since many patters won't really work when the player is paused (since many players will display a doubled field during that time). So it's good to have a chapter repeat function on the player.
