POLL: What kind of video inputs?

I'm working on something new, and I was wondering what kind of signals everyone's video monitors support.

NOTE: Please click all that apply, whether you actually use them or not.

Thanks for your participation!

    Phil,

    If your POLL was supposed to have a voting box, that doesn't seem to be working.

    My desktop (lab) monitors support both VGA and HDMI. I also have a little 7" Haier LCD TV I use for TV video and audio.

    Thanks for asking! :smile:

    Rick,

    It's a weirdness about the way the forum software works. You have to complete the first post to the thread before you're allowed to design the poll. Anway, it should be up and working now.

    Anyway, thanks for the quick response!

    ...just voted - no problems encountered.

    Mine accept either VGA only (the older ones), or both VGA and DVI.

    Voted both NTSC, TV and VGA input on a 20" Toshiba TIMM. Big bulky TV but it has a great pair of speakers. Can plug my Prop Demo board in and test VGA, TV, and sound on the same unit.

    I voted VGA. I am presuming from the "other" description that you did not want this ticked for composite (PAL & NSTC)? - so I did not tick this although I have this available.

    I did not tick Component RGB because while I do have this on one TV, it is not normally used as a monitor (rarely as in not in the last year).

    Cluso99,

    Thanks for the heads-up. I've modified my first post in response.

    What monitors? The monitors we might use with a Propeller, or desktop monitors?

    If it's the latter, you're missing dual link DVI.

    That's what "other" is for. Polls are limited to five choices.

    Rabbit ears? 300-ohm twinlead? Kinda old school these days, I suppose.

    How long 'till we find out what amazing new thing you're working on, PhiPi?

    erco,

    Much depends on the answers to the poll and whether or not I can actually pull it off. Right now, I'm staring at a nearly empty PCB design, having been placing components and traces, only to rip them up again, for more than a week.

    Some of use still need 300 ohm for our CoCo 2, CoCo3's :)

    An empty PCB is like a blank canvas to a master. So much potential, so many possibilities that sometimes it's hard to start. Once the ball gets rolling and you get the big chunks in place, the rest comes more easily.

    ... until you realize you're a pin short. (That's actually what prompted the poll.)

    A clever guy like you won't let one silly little pin stop you. After all, you're PHIPI, for heaven's sake! You'll do the right thing.

    A flash of inspiration or workaround will come when you least expect it. Reverse the polarity! Charlieplexing! Shift register! One pin, many switches! Nanotubes! Bluetooth! iPhone! Download the app!

    I've got a couple with VGA and some flavor of DVI.

    Phil: Only a week! Gee I can take months on a hobby pcb. Obviously I cannot do this commercially though.

    While I prefer TV (NTSC/PAL) because it uses fewer pins and a nicer connector (I use 3.5mm stereo or AV4 now - well always the same connector, just connect the pins required), almost anyone can get a working VGA monitor, even if it is the older tube variety (just drive around the streets here looking for a discarded one).

    The one thing I dislike about VGA is its cumbersome connector, particularly with smaller boards - many of my new pcbs are smaller then the whole VGA plug. I have thought about using a 1x6 pin header (straight or right angle) with the pins GND, VS, HS, B, G, R in that order. With this method, it is possible to use both the AV4 (for composite) and header for VGA. The downside to the header is that a cable must be made.

    Yeah, no kidding. I was rather hoping that YCbCr would be more popular, since there's a standard of sorts that uses a 7-pin Mini-DIN, and the conversion cables from the DIN to three RCA jacks are dirt cheap. Moreover, it uses a composite sync-on-luma, which not only solves my one-pin-short problem, but also makes a certain DAC issue more tractable. But I don't see a lot of response for that, so I'll put it out of my mind.

    Too bad. I love that format. Ah well. I'll probably author a driver at some point.
