depends on what your latency requirements are

you can try a decklink card if you dont need low latency

you can also try intensity card with hdmi straight from computer - but hdmi can be very tricky to set up
and only some computers like outputting at a resolution which is compatible with decklink hdmi - they only work at certain screen sizes set by hdmi edid

you have to test these things yourself

you can also try these:

Any other suggestions?

Will the difference in cost between a DVI2USB and the above be worth it, regarding the quality of the projected ppt?

Thanks,
