Hi, everyone, I've never posted but have routinely found great help on these pages when I set up my system many years ago. I now have an issue that should be simple but I can't seem to figure it out. I've searched the forum for answers and didn't find exactly what I needed. Hoping someone can help.

Nephew just moved in and brought his Xbox 1 and PS4. I'd like to set him up on my Sony 1272Q projector with a MOOME HDMI card installed, that I've been using for satellite and BluRay, running 1080i input with no problems. When we connect either of the nephew's systems to my projector, the picture looks great for 1-2 seconds and then looks like it's in bad need of convergence, and it stays that way regardless of changing from 1080i to 720p.

Thanks for any help anyone can give me.
Mike M.

Set for 720P and re-converge your projector. Sounds like your original input 1080i has different timings than the new 1080i output from the Xbox and PS4. I know on the PS3 the 1080i signal timings via HDMI had a very narrow front and back porch video timings causing issues with the CRT projectors. LIkly the PS4 will be similar.
I never did get a chance to try the Xbox 360's HDMI output but may be the same.

Best option I would say is to start from scratch. Put a 720P signal into the projector, center all the settings on the SONY to 128 and do a full setup.

Thank you for your input! Are there any other options you might know, besides downgrading my picture quality to 720P? Maybe something like a new MOOME card or scaler?

I really appreciate your time on this issue. Thanks,
Mike

It's not about the Moome card, the Moome card can take 1080p but the 1272 can't handle 1080p.
You could run a scaler, 1080p in and 1080i out. It may add lag to the gaming though. Also 1080i is 30frames per second. 720P is done at 60 FPS.
I've never tried 1080p --> 1080i on my 1272. It might look OK, might play OK as the PS4 would be doing 60FPS. It would be an interesting experiment.

Wait, the Xbox One does 1080i? I thought that Microsoft wasn't going to permit interlaced resolutions?

Thanks, AnalogRocks. I was just checking because my Moome card is a first gen card and I thought maybe the newer ones might work better. Just checked, correct, the Xbox One does 720p and 1080p only, no i's involved.

Looks like I may be reconverging for the 720p unless I can find a cheap scaler. Thanks for all your help.

For video games you want to do 720p. Don't bother with 1080i, unless the picture is softer with 720p (because of the increased video bandwidth requirements).

Yes, 720p is (usually*) put out at 60 frames per second where as 1080i draws even lines then odd lines so it's more the equivalent of 30 fps or more correctly 30 fields per second.

* many dash cams and mid 2000's video cameras only did 720p 30fps. Usless information that I know. Smile

I propose a PC an 1080i60 (well, you could also try 1080i 72 or 75Hz). If you want gameplay like on a console, get a game controller for 20 bucks on amazon or ebay.
You are so much more in control of timings and overall picture quality using a PC with a CRT projector in any case.

That explains it, thanks! Thought the 1272 can easily handle 1080p.

I have to agree with AnalogRocks on this one.

While the 1272 can accept and display a 1080p signal, what he means is that the resulting image will be too soft or smeared to be usable. It is best to use 720p or 1080i on this projector.

The 1272 with the 8" tubes and lower grade ES focus just isn't going to be able to actually resolve anywhere near 1080p. Put up some on/off pixel test patterns at 1080p and see - you won't be able to make out the pixels at all. You'd be lucky to do so even at 720p.

I tried 1080p on my 1252 once by accident. Smeary mess and the projector ran supper hot. 1280x720 ran pretty good and the PS3 ran into the HDFury nicely. 1080i looked great for Bluray too. 1272 is basically the same projector.

Thank you for the explanations, Kal & AR. We tried 1080p and it really got super hot.

My other favorite resolution back in the olden' 4:3 days was 800x600 or 1024x768 depending on how your tubes are.

If you are running a home theater PC into it or a scaler either of those resolutions are easy to set up via VGA to 5 BNC cable RGBHV.

It may also be do-able via HDMI though sometime HDMI from a PC is a little flaky.


BUT for Xbox One you might want to stick to 720p.

Alright maybe I will stick to 720p.

Well, it's still a shame to be stuck to 720p with such hardware... Are there comparable issues with the PS4?

The source used doesn't matter. Resolution is resolution. What creates that resolution doesn't matter. So yup, same issues.
