I am upgrading my short throw projector. I currently have a BenQ W710ST which serged us great, but is reaching the end of his life. Given what I am upgrading from, I think I'll be very happy with something under $1,000.

I need a short throw: distance to wall is 70' for a diagonal image about 110'. We use the projector exclusively for watching movie: no gaming. The projector is on a coffee table, about a foot below the lower level of the image. The projector is connected to our sound system.

The room we use has some ambient light, there are some open windows with some street light, but nothing to close. I am hesitating between the BenQ TH671ST (more luminosity, less contrast), and the BenQ HT2150ST (less luminosity, more contrast). Given the constraints of the room, which one would you suggest? I am open to something else, but from looking at reviews here it seems that these two are my best shot.

Thank!

Your lens to screen distance is between 69" and 74", which is a very tight range if you must keep the projector exactly where it is.

The most direct upgrade to that model is the BenQ HT2150ST.

What you have now is decent, and the upgrade will be a solid one, but at this time there are NO short throw 4K projectors on the market.

There also hasn't been some major revolution in terms of price/performance/quality of projectors overall. That is, pricing has dropped a bit. 1080p has replaced the 720p price point, kind of.

Short throw 1080p projectors of decent quality in the home theater are few and far between. But, Optoma has the GT1080 as an option (check throw distance) as well.

At the end of the day, if you've been happy with your BenQ, then getting a new version with higher resolution is the way to go. The HT2150ST is considered the best entry level short throw DLP projector on the market. The price, at $850, is right on target as well.

Hopefully we will see a 4K version come out in the next year or so as this specific throw distance is not available in any 4K model which I am aware of yet. It will likely be about $1,200-$1,500 for a short throw 4K model when it does become available.

Just a note: It is recommended you always start a new topic/thread for a new question/conversation.

Unfortunately, the specific technical details of electronics work is not really covered by these forums, or any other forums related to projectors that I've ever seen.

The best resource I have seen online is from FixItFrank on YouTube. You should go there and send him a message. He may be able to help you out with your projector specific repair.
