Would anyone recommend one over the other for LCDs? or perhaps another calibrating DVD you prefer for LCDs?

Either works fine. I like the full range ramps on DVE which can be additionally helpful on digitals.

However there is also the getgray disc which might be more useful specifically for digital displays.

Add to that the Avia and DVE filters are not the same. The blue filter in DVE is darker, has more of a violet coloration.

Which one is right? does it make a difference?

I don't know who AVIA sourced their filters from. DVE obtained theirs from GAM. DVE re-evaluated all the major manufacturers' filters prior to the initial release of 'Digital Video Essentials' and found that GAM was producing the best and most consistent stuff at that time. Common sources for these filters include: GAM, Lee, Rosco, Kodak, and maybe others.

Can DVE be used with a HDMI connection? It says "component" on the DVD case?

Absolutely.

DVD is a component-video format. As are basically all the digital home-video formats. Every DVD is this way.

I've used both on the same set and gotten identical results for saturation and hue. Wouldn't a difference in shading or hue of blue have impacted this and rendered different results?

It depends how the filter interacts with the SPD of the display. It may or may not cause a difference.

The AVIA and DVE blue filters both work fine for me and produce identical settings for color+tint settings. The red filters are very similar too, as are the green.

BUT, both AVIA and DVE green filters allow way too much blue trough! I know that you are only supposed to set color+tint using the blue filters, and that red and green filters are there just for verification purposes, but many people think that you can actually adjust individual color settings while watching through the different color filters, and if you do this (which .. is wrong) without knowing this aspect of the green filters, things will be .. more wrong.

I claim that when looking through the green filter on colorbar patterns, you should look at white and CYAN, not green, because cyan and white are the two colors with the same amount of both blue and green in them.

I'm quite surprised that I haven't seen this being mentioned anywhere.
