Yes, the 1080P is higher quality, but it is mostly noticeable on larger monitors (32" and up). If you are on a laptop, you won't notice much difference, but the easiest thing is to try one. 1080P does require more computer horsepower and takes longer to download as the file size is larger.

The Full HD files are at least 2x larger files then the 720p so you will have a much better quality image for sure.

Well even with a 720p projector going to the Full HD would double the bitrate, it should increase the contrast & massively decrease the artifacts..I can not imagine watching the 720p on a 80" display. Obviously the image from a video file that is Full HD & more then twice the bitrate will be massively sharper with a Full HD projector at 80".

Normally there can not be any visible artifacts at all if your downscale our full HD to 720p, its just going to be half as sharp.

Which rides are you looking at? Recent films made since 2016 come from 4K cinema camera & have a fair bit less compression & look sharper, although I think with a 720p display its not going to be a huge difference....rule of the thumb is 'bits = quality' & if you double the bits you will increase the quality ;-).

That is likely a contributing source of quality issues. If your projector is 720p/1080i, then an HD (1080P) may not show much improvement, but I would still give it try to see what happens. If you have a 16:10 projector (1280×800, 1440×900, etc.), then you might get some improvement. Phil can correct me, but my guess is his SD videos were mostly captured with a higher resolution and have been downscaled for SD.

Yes its all downscaled & for the last 3 years its downscaled from 4K, Im 100% sure that going with the FullHD will remove more or less all the artifacts as 720p does have artifacts, the file size is often more then half the size of the Full HD...your going to see them in all their gory detail with a massive 80" display. Going Full HD will mean your only downscaling. If its artifacts that you want to remove then doing this should be the solution ;-).

I would download an HD demo and try it. With only 800 lines in your projector, you are not getting much above 720.

Mike I think the Demo rides are all 720p he would need to just take a months full HD subscription. Ive said that going Full HD will remove more or less all the visible compression artifacts. Obviously, a 720p film with Artifacts of which there are will be visible on a huge display like he has...he needs the Full HD which when downscaled will not have compression artifacts that the 720 has, it will be just losing half its sharpness..

I thought there were HD demos. But if not, you are right. There is often this trade-off between sharpness and artifacts. You can gain one at the expense of another.

No idea, Every ride filmed in the last years has a 4K version, we have 4k in closed beta since the start for PC (not Mac) but never really had a discussion with Tacx about their plans for it. If they did do it there will be a extra cost as these are twice the size of the Full HD. Just now most the customers are content with crappy 720p sadly although it seems the % going for the full HD is growing

720p ain't so crappy... given the exquisite film contents and the very small amount of oxygen left in my brain during most rides, the image quality is great, even on a 55in TV.
