BenQ TK700 4K HDR Gaming Projector (Factory Reconditioned)

*Update* I talked with BenQ after I returned the previous projector and they suspected it was defective. They informed me that the TK710STi’s made after November 2024 have addressed a few issues, mainly an issue with light spillage on the left side when ceiling mounted. So I ordered another one and even though it was manufactured in October, it’s much better than the last one I had. The bottom and corners still aren’t perfectly sharp like the center of the screen, but it is noticeably more sharp than the last one. And for some reason this one isn’t as loud as the previous one either. I use it on eco mode since I have a moderately light controlled room and you barely notice it when playing content. Some wonky things still happen with the connections and when switching between content. Sometimes when I power on the projector it automatically turns everything else connected to my A/V system and starts popping my speakers. To fix it from randomly switching between HDR and SDR on my Roku, I set the Roku output to 4K 60p rather than automatic. At this point I don’t necessarily care about HDR video content and am fine with just 4K. Overall it’s a much better experience than the last one I ordered and I’ll end up keeping this one. —— This was meant to replace my TH671ST but I ended up returning it because the overall experience wasn't worth the upgrade. Maybe the internals got misaligned during shipping, but mine had terrible focus uniformity compared to my TH671ST. It would be sharp in the top and center but was blurry on the bottom. The bottom left corner specifically was the worst and would not go away no matter how much you adjusted it. I only had -1 on my vertical keystone to compensate for my walls not being perfectly straight, but that is nowhere near enough keystoning to throw the focus off that much. You couldn't really notice it when watching content but it became very noticeable when scrolling through menus and catalogues. It also wasn't ideal for gaming since there are usually HUD's, maps, and stats on the corners. Other Negatives - The TK710STi is fairly loud when in normal light mode. Luckily, since this has a high lumen output, it was still bright in Eco mode which quieted the fan considerably. The decibels are about the same as my previous projector but the TK710STi had more of a buzzing sound than a fan sound. I probably would have gotten used to it after a while but I did not really like it. - The video signal would occasionally black out, glitch to a green screen, or boost the contrast and saturation. This mostly occurred when you started a show or movie and it was reading the video signal. When I'd back out of a movie to my Roku menu it would get stuck on an over-saturated image and I'd have to either turn the projector off and on or switch back and forth between HDMI inputs to fix it. I have high-speed 4K HDMI cables and this never happened on my previous projector. Positives - Despite my focus issue, the image was still very good. There was a noticeable difference when playing games since this projector has HDR capabilities. I also could tell the TK710STi had a significantly higher contrast ratio compared to my TH671ST (60,000:1 vs 10,000:1). In dark scenes this one excelled at presenting blacks without noticeable banding or gradations like my 671ST. - The remote is a big improvement from other BenQ projectors. It has Bluetooth so you don't have to point it directly at the projector to access the menu or volume. I was quite dissatisfied with the TK710STi and felt it wasn't worth spending $2K to upgrade from my TH671ST which is a really good projector despite it being 1080p. I purchased a new lamp and will likely wait for the next iteration of this projector or just eventually transition to a 100" TV a few years down the road.
