There is a Runco 1100 I can pick up locally. It has about 3500 hours and some wear on the green tube. Would it be a worthwhile upgrade to my G70? I am at a crossroads with the G70. It has 3500 and also needs a new green. Thoughts on a fair price? Anything to look out for?
Thanks,
Tom

A good set, but... it will most likely have image wraparound because it's a Data 1209s, not a Graphics. The pix will lock, but the only HDMI box I was able to get working on it without a bit of wraparound was the Moome box. The Fury2 had wraparound. the 3 wasn't out to try on it.

Just FYI. If you put a scaler on it that can adjust the front and back porch settings, you'd be OK I think.

Thanks Curt,
Once I purchased a scaler and a new green tube, I'd be back in G90 territory, so I think I'll pass.

Curt, is the wrap around image something unique with the HDMI boxes? Reason I ask is that my Runco 1100 has absolutely NO wrap around issues at 1080p but I use RGB from an HTPC. That said my Runco 1100 is a later version that has some changes boardwise from the earlier models so maybe that is the explanation. Bottom line my Runco 1100 has no problem with 1080p from an HTPC. W9TR I wouldn't count the green tube against the Runco since a $1000 G90 would need a green as well. I'd try to talk the seller down a bit, the Runco 1100 throws a great picture it isn't quite a G90 but it isn't that far off either. If it were closer to me I'd pick it up just to get a lower hour chassis as mine is around 14,800 hours these days.

Well, spec wise it says it will do it, but I sent an 1100 to Alan Gouger, and he experience the wraparound. I kept telling him to try an RGB source, got lots of info from Greg Eisemann and MadMrH about what boards to swap, blah blah. After about 3 shipments of boards, I got Alan to send back the unit and refunded his money.

Once I got the set back, it turned out that the Moome external box I used to test the set was perfect at 1080p, but the Fury1 and Fury2 (which Alan was using) caused wraparound. I haven't tried the Fury3, as this was a couple of years ago and it wasn't out yet. A scaler between the source and Fury or Fury and projector should solve the problem as well. Alan had a scaler, but I don't think it had front and back porch adjustments, or we didn't try that at the time.

As for the info and board swap, it was really a bunch of nonsense, as both Mad and Greg told me a number of different things over a few weeks, and in the end gave me sh*t for selling the set as a 1080p capable one. Turns out you can't swap the crucial boards between the Data and Graphics, as a bunch of the board combinations won't work. The controller board software is what limits the scan rate in Barcos (I always thought it was the H board until that time), so in order to get rid of the image wraparound and to turn the set into a Graphics 1209s, the only 'proper' way to do it is to swap a full set of boards over from a BG1209s. Fortunately I've got a few BG1208s with low hours on them, so that's what I'll do with this one.

So, net result: the Runco 1100 will work fine at 1080p under some conditions/sources, but it will show wraparound on a bunch of combinations.

Curt, thanks I guess I am lucky. My Runco 1100 is a later model 5/2000 and is not strictly speaking a Data 1209s. Unlike the earlier Runco 1100s that say Data 1209s on the yokes mine does not. There are also some differences between the boards in my Runco and the Data 1209s The vertical board is R762637 vs. R769003 (in the Data 1209s). Also the horizontal shift and focus board is a R7625035 (same as late model 808s Graphics) vs R762271 in the Data (and other 12 series projectors). Perhaps those differences explain my luck. My G2 board is also a different part number but I cannot see it making a difference but it is R763014.


Edit: I should add that I run powerstrip on the HTPC and ran a bunch of different timings from default to greater porch settings to avoid raster ringing and it never wrapped around. Again maybe I am just lucky.

My Runco 1101 12/01 build date had the wrap around issue with the fury 1. I was able to get around this with the vp50's porch adjustments but could never get proper gamma even with the box 1020. So I ditched the whole chain and now feeding it with rgb via htpc.Powerstrip takes care of timings and Video equalizer takes care of gamma.Best move I've made since getting the CRT.

Mike, thanks I didn't realize Nvidia could do this natively. Next upgrade I will move back to them. I dropped them when the 8 series cards came out and Powerstrip no longer supported them.

Old thread-similar issue!

I have the wrap around at 1080P/60 with my Eisemann DVI modded input via an HDFury. Is it safe (tube-wise) to blank the left and right side image to cover the wrap around

I have been using my HTPC, with custom Nvidia timings, to get a successful 1080p/48 (JohnHWman suggestion) directly to my DVI input with no wrap around. With the HDFury, I am testing Bluray performance from a PS3 to see if I get "MORE" (as usual). I do not have a VP/scaler to add to the mix.

Thanks

Sure, you won't hurt anything with using blanking. Lumagens now (HDP units) are going pretty cheap now though. Grab a used one of those, and use it to adjust the timing/width of the image.
