THe pics to be shown are on a DVD. Can I run the DVD on my laptop and project them onto the screen from there?
And no, I cannot darken the hall where these will be shown; as on whole side of the room has windows viewing a courtyard.
I'm not aware of any details of this entire operation except I've seen it used by others.

I create photo shows with Pro Show Gold. Go to Photodex.com and check it out. You will not be disappointed. My D7000 has 16 mp and images on my 40" LCD TV are just fine.

I've been asked to make a presentation of some of my recent photo trips. Having never done this before, my first question is about detail and sharpness. If I place all of my photos to be shown on a DVD, and project them onto a screen, will the quality get worse the larger that I blow them up? The pictures have been taken with 10, 16 & 20 megapixels. The last thing I want to convey is poor quality images to the group.
For what it's worth, I have made prints as large as 16 X 20 with fine sharpness and detail. But projected images will be much larger than this.
Thanks.

I wouldn't worry about it. First off, most people that aren't pro photographers aren't going to say "hey, sure is a lot of noise in that pic". They don't see it at all. And a pro photographer isn't going to think anything because they would know that projectors aren't the best media for displaying a photo for the reasons you are concerned about. Besides, if your projector isn't color calibrated, your colors won't be exact either.

If you take all the best suggestions here the images you will see will be bright, high contrast, and slightly over saturated in certain colors. If you don't like high contrast and oversaturated reds, yellows and blues, too bad. This is what you will get.

Most laptops have an HDMI out port. Most TVs and projectors have an HDMI in port. Theoretically HDMI cords are supposed to be pretty short. I have one that is 15 feet long and it works fine.

Just save your pictures as JPEG on the DVD and not to make it a DVD movies disk. You can use a thumb drive instead. Correct me if I am wrong that you don't know what kind of projector it is right? If so don't crop your images at all. The quality of your images will be greatly dependent on the projector.

That was my point. All projectors and TVs also pride themselves on being high contrast and having punchy colors. You couldn't get low to normal contrast if you tried. I've tried everything.

You need to find out what is being used as the "large screen".

Current TVs, flat screens or projectors, come in two sizes now. HD and 4K. HD is 1920x1080 or about 2 megapixels. 4K is 3840x2160 or about 8 megapixels. Projectors or flat screens.

Most of the newer ones have USB ports for thumb drives ors hard disks. You control the slide show with the TV remote. If you put image files on a DVD, you add the unknown of the DVD player quality. If you "burn" a DVD it will have terrible old SD (standard definition) quality.

My personal best results are exporting "display" copies using Lightroom with pixel dimensions for the 3840x2160 screen. However, my Samsung 4K TV is pretty good at rendering any JPEGs of any size.

However, the OP wants to project files burned on a DVD. The highest resolution that the DVD format can support is 720 x 480 pixels per frame.
