Last night I did my maiden run of my new promotion.... and althought the 2500 lumen svga did the CG's just fine...when I ran a Led Zeppelin dvd.... not so great for that....will a 2500 lumen xga make a difference in the quality that is noticeable do you think? Or do I need to go to 300 lumens, or deveral hundred more dollars. The brightness in the room was not an issue.
