Projector comparisons

@esthlos13 Projector People is an online retailer of projectors and accessories. You can find them by using a search engine.

In my experience JVC's projectors provide superior image quality, and I've also heard good things about Sony in previous years. So my recommendation for brands is aligned with auxinput. JVC's projectors also have auto-calibration software although it can be fairly confusing and tricky to use at least on the older models.

I also recommend getting an HDR 4K (probably with shifted faux-4K, considering your target parameters) projector with that supports 18Gbps HDMI connections. Some faux-4K projectors only support 14Gbps HDMI connections (e.g. some Epson) which is going to create problems for you. In addition to the increased pixel detail, HDR provides more realistic colors. You won't get the same maximum brightness from a projector that you can from a regular TV, so the brightness part of the HDR will be less of a benefit. Some people prefer to convert 4K HDR sources to 4K SDR because of that.

@esthlos13 you could also consider a long HDMI cable that uses active transmission (chips at the send and receive connectors), as an alternative to HDBaseT.

@karlbee a new thread would have probably made sense for your question, but the laptop's manufacturer provided specifications should indicate what resolution and refresh rates it supports over any HDMI video outputs it has. That's the only way to be sure.
