hi,

i need gamma adjustment (now-ish) and will be getting an hdmi source by the end of the year. also rolled into that roadmap is digital TV of some sort but that is further down the road as my "TV" is an old sony 27" 4:3.

finally, i need to continue support of my old Laserdiscs and VHS for those movies that just aren't on other sources. the scaler makes them bearable IMHO. i run them at 1280x1024@72 (also what i currently run my DVDs at).

the two options seem to be either Moome's extHD with gamma or an HDFury/RTC-2200 combo. the later has the edge as it available now, has had rave reviews and lets me get gamma now until i decide on the hdmi source in 5 months.

if i use moome's extHD, i'll hook it up like this:



but i have two options for using the HDFury. the first uses the extron to scale down the image to 1280x1024@72 before it hits the projector. this means that the PJ always sees the same input and i'll only have one memory location on which to maintain focus/convergence/etc.



but the extron has a VGA passthrough input that would allow me to pass the HD all the way to the PJ. the upside is input to the PJ that is more pure but the downside is i'll have two memory locations to tweek/adjust chase.



am i missing anything here? does the moome gamma circuit affect both the component and the HDMI input? is scaling the HDfury output down going to kill any advantage of the HDMI output? i doubt that the XG852 will handle 1080p - heck i don't even like 1600x1200@60 on the XG852 (too much judder for me). should i wait for moome and do HDMI and gamma together? or should i get my gamma now with the RTC-2200.

i know that moome is creating an HDMI card for the XG, but that is months away and while it will have gamma, i still won't have gamma on the other sources (they need them too , and i really can't run an HDMI cable to the PJ since the great ceiling drywalling of 2006...

A Lumagen videoprocessor. Don't know if the absolute oldest ones support gamma, but most seems to do since a few years back. DVDO ISCAN, blah blah blah, don't, unless you get the newest Anchorbay's VP* ones, they do gamma. (But make sure you have as much range in the gamma controll as you cans ,ome don't offer that much.)

The old Taw Rock processors have gamma adjustment which I have have used with good result

Zaphod,

Why do you run your VCR and LD at 1280x1024 resolution?

I can of course understand the gamma need, but how would, at least, the LD picture be if you got an LD player that had component output (didn't some VCR player have component output too?), instead of running through svideo?

(From my current dvd players component output is brighter than svideo output, so "less need" for gamma.)

(Extron doesn't seem to exist in this country, so it's Extron what?)

There were some of the LD players that also played DVDs, I do not remember if any of them could use the component outputs for LD and DVD, I think most it was for DVD only.

nope, not even the pioneer last generation of players had component outputs, S-video was the tops of the day. check out http://www.laserdiscarchive.co.uk for info on various players.
