I use fiber cables from RUIPRO off of Amazon. They have a number of different models, but they are all high quality from what I've used.https://www.amazon.com/dp/B092ZQ332Q/ref=dp_iou_view_item Not cheap, but should last for years without their internal electronics blowing up.

You need to focus on light control. I have used the Valerion Max with the Silver Ticket WAB screen and it looks phenomenal. So, I would expect similar results with the Horizon 20. Be aware that cheaper fiber HDMI cables can fail early on. They work for a year or so, then the electronics inside of them fail. The RUIPRO cables are what I have standardized on due to their high reliability long term. If the HDMI cable run is tough, run 2 HDMI cables at the same time. https://www.amazon.com/RUIPRO-Fiber-48Gbps-Dynamic-Samsung/dp/B092ZQ332Q/ref=sr_1_1_sspa
