Optoma UHD35x Features

  • Great picture
  • Excellent for bigger or smaller rooms
  • Bright lamps for bright rooms


  • Weaker in the UHD35 in some aspects

It can be difficult for you to know the difference between these two, especially since the specs for the UHD35x are sometimes mistaken for the UHD35. In general, the UHD35x offers similar features to its UHD35 counterpart. Both are 4K, offering beautiful pictures. However, the UHD50X has a wider lens, which is ideal for smaller rooms.

In addition, it offers a 500,000:1 contrast ratio with 3,400 lumens. So it still offers a fantastic picture, but as you’ll soon find out, it may not be our preferred choice.

Optoma UHD35 vs UHD35x Comparison

Video Quality

Both deliver 4K video, but the UHD35 has double the contrast ratio for a much sharper picture and more lumens to make your movie look brighter in a bright room. In addition, the UHD35 does have video upscaling. This means you can turn a 1080p movie into 4K. We tried it and were impressed by how sharp the picture still looked.

However, the UHD35x does have a wider lens, making video look better if you are in a smaller room, giving it some versatility. By and large, however, the UHD35 wins.


Both work well for gaming, but the UHD35 has a better gaming mode. You can play games with only 4.2 ms of lag by sacrificing the resolution. Meanwhile, the UHD35x is around 15.7. Fifteen milliseconds is still good, but you need game lag as low as possible if you’re a competitive gamer. Even a millisecond more lag can make the difference between winning and losing the game. For that, the UHD35 is more versatile.


The UHD35 and UHD35x are around the same price. This price can differ depending on what site you’re visiting or what time of the year you’re purchasing your projector. However, there is usually no significant difference between the two, meaning those on a smaller budget are not limited to one due to a significant price difference.

The Verdict

Overall, there’s not much reason to buy the UHD35x over the UHD35. The naming scheme is confusing; the x would signify an enhanced version, but this is false. It’s a nerfed version of the UHD35 with a price tag that does not justify it. You may benefit from the UHD35x more if you have a small room. However, the UHD35 still works well in those rooms. With half the contrast ratio, fewer lumens, and a more lag-filled experience, we have to choose the UHD35 (>>> Find on Amazon).

We hope this article was helpful to you. With that said, many other projectors are out there, meaning that you may want to check our other comparisons if you feel these two did not meet your requirements.
