I have an XG1352LC which of course got dirt cheap with new tubes and calibrated by Ken. Its been a great PJ and I’ve always used a scaler. (IScan HD+) My scaler does add quality and flexibility to SD sources.
When I got my PS3 I thought I would be able to view 1080p @ 60 direct from the PS3 without a need for scaling. Wrong, wrong, wrong due to timing/sync issues.

https://www.curtpalme.com/forum_archived/viewtopic.php@t=10767.html

So now I need to deceide.
Do I
A)Be happy with 1080i/60 from PS3. This does look great but I know I can improve significantly with either increasing the scan rate or running 1920 X 800 @ 60 or 72. I currently use 1920 X 800 @ 60 from an IScan HD+. Until I got PS3 this was by far my best source and I know the XG resolves this with no issues.

B)Get a scaler like the VP50, HDP or higher. This option gives me the best possible image but reduces my bang for the buck factor. Even a used HDP or VP50 will cost me close to what I paid for the XG.

C)Switch to HTPC. This was my pre-scaler setup but I switched to the scaler for the simplicity. Now with diligent programming of my remote the whole family including my seven year old son can operate the system and take full advantage of the various resolutions and ref rates I use. I have to admit the HTPC certainly has its selling points if you can deal with the complexity.

D) Dump CRT altogether. Sell the XG, the IScan HD+. Put this money towards something like an RS2 which by most reviewers estimations, including Gary’s, is dam close to the performance of the XG and better in many respects. This option lets me get rid of big hushbox, vastly simplify my system and allow me to appreciate the sound system again---- but I’m worried that I would still want a scaler for the primaries.

The more I consider this the more I lean towards option B or D. If I can get a VP50, HDP or higher for under $750 I think I’ll go that route. If not then its option A for now with option D approaching.

Yup, and you need a good scaler too like the $4K Lumagen Radiance to adjust those horribly oversaturated RS2 primaries.

Transcoding, anyone?

I bought my scaler (VP30) originally to transcode from component to RGB. I bought it about three years ago to add a Directivo to my NEC 9pgxtra. Didn't know about the Moome cards, or Fury option. (Not even sure they were available then.)

My setup today includes a HD DVD player, BD player and HD DVR. I use component HD signal from all three to feed the VP30, then RGB to the NEC. AYK, neither the HD DVD or BD player will output upconverted signal through component. I already had the VP30 SDI input mod and chased down a used Panny RP-82 with a SDI output for SD DVDs. Love the PQ from the SDI option, but have not been able to do a A/B comparison between BD upconvert and SDI, obviously.

As I recall, I've seen used VP30's on eBay in the $500 range, whihc makes them in the ball game to compete with the fury and Moome cards. One of the nice things is the ability to program different aspects ratios to a Pronto button, and watch HD or SD on the sat in the correct aspect ratio, via the VP30.

I do HD audio using the HDMI outputs from the HD and BD players into a Pio Elite VSX-84txsi. Works great.

If I had to do it all over today, I'd be hard pressed to pay the list price for a new VP50 today, but would jump on a used VP30.

IMHO, of course.

I think we have the same PJ. I also use a scaler. Just so I understand, if I were to remove the scaler from my setup today, I would loose nothing? How have you come to this conclusion?

We do have the same PJ. Maybe you would lose something. I don't know. But other than adding higher refresh rate options, I don't think I would gain anything by adding one. Shocked

Well, if transcoding is all you need, buying a 1k+ (when you bought it) scaler isn't the way to do it...Kim's transcoders are excellent and can provide gamma boost for under $200. You also talk about a scaler being a replacement for a HD-Fury or Moome card...they serve entirely different functions - no legit scaler will strip HDCP. Also, $500+shipping definitely isn't in the same price league as the Fury at $160 shipped, even if they did the same function, which they do not.

For aspect ratios - I don't know how the NECs work, but programming different recall memories with different aspect ratios on a Marquee is very easy. So instead of reaching for the Pronto, you'd reach for the PJ remote - same outcome, but a whole lot cheaper.

Phil, what resolution do you use for SD on the G70? IME, the sweet spot on this PJ is 960p72 for film. Without a scaler, I do not know how this can be obtained?

He mentioned using analog component, which doesn't have HDCP (thus no stripping).

I find the VP30 to be the more elegant solution in his case. It is one infinitely flexible box, rather than a rat's nest of HD Fury, two transcoders, and a switchbox! Shocked Why would you do this? To save $300.00?

But it isn't all he needed! He stated he is using the VP30 to deinterlace an SD-SDI source.

Ax, HTPC connected via HDMI. I prefer 720P, but could run 960P if I wanted to.

A Moome HDMI card and an HDMI switching receiver/preamp is an even more eloquent solution. With all HD sources, nothing else is needed.

This thread is about the need of a scaler for HD sources, in case anyone's forgotten. I had an HD-DVD, PS3, Dish DVR and HTPC all connected via HDMI. As far as I could tell, I lacked for nothing.

I would agree 1080i is ok, if you want to tolerate the interlace field and 60HZ judder then this is an excellent compromise.

I considered this but I believe you are wrong. There are instances where a a scaler is needed if you wish to run more than 1080i. Here is a link to example with NEC PJs but there probably others with the same issue.



https://www.curtpalme.com/forum_archived/viewtopic.php@t=10767.html


Now I would be real interested in the HD Fury/Moome etc solution if one of the new HT receivers gave control over sync/timing/porches etc. The new Onkyos have elaborate scaling but I'd be very surprised if they have these adjustments.
If they did I'd upgrade my HT receiver and forget about a scaler.

Anyone know if the new receivers have porch controls etc with thier scaling?

I cant imagine using my marquee with out a scaler, I have the moome internal card also, tried it with out the scaler and find the image better with the scaler. also I have too many handshake issues with out it. The Gamma at 11 points the added color gammut controls and the unlimited resolution capabilities my lumagen adds ,for me, is the only way to go.

Steve,

Those problems don't exist with a G70 (for whatever reason). I've experienced the foldover issue with 1080i many times, but it's fixable using the G70's Shift and Center controls.

I concede that XG owners truly benefit from the use of a scaler, but I'm not sure CRT owners of other models would. I don't think I really would.

And like Doug mentioned in the other thread. There are a LOT of 8" LC CRT PJ owners that prefer 1080i.

I rarely notice interlacing problems. 60Hz judder? Yes. But would I buy a scaler just to fix that? No.

My 2 cents:

I have both the DVDO VP50Pro and Lumagen Radiance.

For native 1080p24 sources from Blu-ray/HD-DVD, what do my scalers give me over just using my Preamp:

Spot on primaries and secondaries. (Radiance)
Perfectly flat D65 tracking. (Radiance)
Completely tweakable gamma curve. (Radiance)
72Hz playback. (VP50)
Aspect ratio control for my CIH setup (both)
Tweaks to less than desirable transfers such as edge enhancement and mosquito noise reduction etc... (both)

For 1080i sources I get best possible deinterlacing (VP50)

For 720p sources I get best scaling (Radiance) and if source was poorly deinterlaced, I get PREP (VP50)

Is the $8K worth it? To me it is, that's all that matters.

Some good comments on the pros and cons of scalers, but...

Sorry, but this is just nonsense. You've completely left bandwidth out of the equation, and 1080p either requires twice the BW of 1080i, or leaves you with less horizontal detail and resolution. That's a tradeoff that many are unwilling to make.

> ...and progressive just looks so much better, it is just more easy on the eye. <

Progressive is easier on the eye... especially with a PJ like the XG with it's long retrace interval (compared to other PJs), which spends more than 1/3 of the time displaying nothing at all. This exacerbates flicker and temporal artifacts, in spite of phosphor persistence.

certain people in this thread have let their pocketbooks decide if a scaler is a meaningful addition to a videophile system, this is obviously not a valid argument in so many ways it isn't funny, I don't understand why it even continues

far too many posts like this in CRT areas, stuff like "oh thats overpriced so it isn't worth it and is a waste anyway" or "adds no benefit because I don't want it"

I noticed that no one had any reply to my y/c delay question? don't bother with "I don't want to pay 5k$ for correcting y/c delays" type posts either, that is only a drop in the bucket, I could easily write a book on what a scaler brings to CRT, discussing if a scaler is a thing of the past and giving the reason is that they cost too much is just amazing!

That's why I have inlcuded the word spatial in the sentence. Furthermore I was talking about all good 8" EM CRT's, such as the G70 or the BG808s. On those projectors you are not running into bandwidth problems or losing horizontal resolution.
Even if you projector is not set-up well, and not resolving that last pixel, the de-interlaced picture still looks better, and a 72hz film image still looks better. But that is ground for another discussion: Better (native) scaling or running a projector at its optical sweetspot. Moste people go for optical sweetspot, while I prefer the other.

Maybe you were referring to 8" ES entry models, such as the Sony 1251 of the BD800?

There goes that hair again Wink
Anyway, there are those who feel that a scaler is a must and I appriciate that. I never said there were not benifits to them. I am wondering what direction the manufacturers will take as source devices evolve and the masses choose the easy path. Let's face it, we are a minority in the eyes of the latest brew of electronics. They exist to generate revenue. If everyone on this forum bought a VP 50, that would only amount to a drop it the bucket in the eyes of the bean counters.

Choosing with my wallet??? I've got a home to pay for, a wife and children to provide for, children to put through school, cars with insurance and GAS to consider. I need a new riding lawn mower and now this Y/C delay thing. Laughing
