Which Has a Better Video?

Both produce stunning 4K video that’s fit for home theater setups. If you choose either, you will undoubtedly be greeted with vibrant colors, bright pictures, and gorgeous graphics for your video games. (You can check out the roundup review of the best 4K projectors for gaming on Projectortop.com.) 

However, the UHZ50 looks better overall. With double the contrast ratio, everything stands out more. It has a much sharper picture, especially for the experienced reviewer. Some people may not tell much of a difference, but objectively, there is only one option here.

Which is Better for Gaming?

Both support similar gaming functions, with lagless gameplay up to 4ms. This means you can play competitive games in your home theater and create an environment that puts everyone on equal footing. We choose the UHZ50 because the picture looks sharper, and the contrast ratio may help you in certain situations.

What About Sound?

Both support speakers, but which has better sound in a vacuum? The UHZ50 excels in sound due to its eRAC support. The sounds were much clearer, and we felt more immersed while watching. While the UHD55 still has some fantastic sound, we have to choose a clear winner, the UHZ50.

What About the Price?

The UHZ50 is more expensive than the UHD55 because it’s more advanced. While the price can vary depending on sales, this may affect your decision. If you have a tight budget, deciding whether to pay extra for more features and a sharper picture is a question you must answer. The UHD55 suffices if you have a tight budget.

The Verdict

This comparison was a no-brainer. Because we’re comparing two of the same brand, the more expensive of the two, the UHZ50, will naturally have better sound, better picture, and better bells and whistles.

This sentiment is not to say the UHD55 isn’t a great projector. If you are on a smaller budget, you should buy that, then spend your money on equally powerful speakers or receivers. However, if budget is not much of a concern, we must go with the UHZ50 (>>> Find on ProjectorScreen). With better contrast, you will be immersed in your movies like never before.
