The "passthough" option basically doesn't exist on most provider boxes these days. This is because the menus, etc are now HD. You basically need to choose one output resolution and 4K is probably the best option. It's rare these days that one (relatively new) device is significantly better at conversion than others, unlike 10-15 years ago.
You could try 1080i since most channels broadcast as that, but you'd still have conversion for 720P channels and you probably wouldn't be able to tune 4K channels, although there's very little 4K content available... Here's an FAQ on the topic.
https://www.digitalhome.ca/threads/faq-hdtv-formats.76129/#post-654997
1. There are no 1080P channels, so not sure why you'd want to introduce deinterlacing in the box and then upconversion in the TV.
2. If you use 720P that would be terrible for 1080i channels and 4K incoming signals.
3. Try various options and see if you can actually see a difference. If you don't see a dramatic difference, I suggest 4K so that you can continue using the box apps.
I'm still on Digital Cable, but AFAIK, per the FAQ, most channels broadcast 1080i, with some channels 720P and a select few 4K. I believe that on IgniteTV those signals are passed directly to the box by Rogers and you then need to decide what output you wish to set the box to. Again, I suggest 4K unless you see a degradation of the 1080i/720P channels for example...
I don't recall anyone ever confirming what the incoming signals to the IgniteTV box are for the various channels. That's easily confirmed in the diagnostics of the digital (Nextboxes), but I'm unsure about IgniteTV. Anyone have any knowledge on this topic? @-G- ?
I thought that only Bell and those who receive signals through Bell are downconverted to 720P for normal TV viewing.
What's the make/model of the FP?
Sometimes handshakes between various devices don't go as planned. Can you set the output of the box to 1080i when directly connected to the FP? Have you updated the firmware on the FP?
hmm, website says, part way down comparing 720PX to 1080PX:
High Resolution: The true native 1200*1080 pixels resolution projector delivers bright, clear display while creating vibrant colors and detailed images for a better viewing experience. It is ideal for families to immerse in big-screen entertainment.
In order to be 1080P you need 1080 x 1920 pixels. If this FP is only 1200 in the horizontal direction, that may be the issue, or that may simply be a typo because other websites say 1920, but who knows - those sites may just be parroting the "claim" of 1920...

Have you tried updating the firmware on the FP as that can often cause handshake issues. Try connecting the Rogers box to another TV and set it to 1080i or 1080P. Then connect the box to the FP and see what happens. If it works, good. If it doesn't, sounds like a handshake issue, or the FP really isn't true 1080P. It's not the first time that a "claim" is not the reality...

IPTV works differently than broadcast/digital TV. With Rogers Digital TV, the incoming signal is received from the source, undergoes some processing (usually compression) at the source and is then either broadcast or sent via switched digital video with its native format preserved.
You can't stream an interlaced signal, so a 1080i source signal would get deinterlaced immediately at the beginning of the encoding pipeline and then simultaneously transcoded into multiple resolutions and bitrates. The quality of the stream depends on the quality of the deinterlacing and frame rates that the IPTV encoders can produce. Ignite TV also streams with an adaptive bitrate, and the streamers in the back-end will send a stream that's optimal for the device that is receiving it. That's the general gist of how things work in the IPTV world. Implementations vary and I don't know many of the fine details that are specific to Ignite TV.
As far as I can tell, Rogers seems to be sending all HD channels to me as a 1080p stream, including those (such as NASA TV) that are 720p at the source.
On a 4K TV, I would recommend setting the HDMI Video Output Resolution on the set-top box to either 1080p or the Best Available (4K) depending on whether you want the set-top box or your TV to perform the upconversion. I would personally set the Ignite STB to output 4K unless there was a good reason not to.
I would only set a 1080i output on the Ignite STB if I had an old TV that could not process 1080p, and if 1080i was the best available option.

Tried box that was off my 1080 tv, as soon as it plugs into projector it goes to 720P. Also checked it on my kodi box and system settings shows resolution 1280 x 720P. Maybe not really a 1080 projector ??
Yes, but did you set the box to 1080P while it was connected to the TV or did you leave it on "auto". You need to set it on 1080P for the test to see if that signal will "get through" to the FP. If the (1080P) signal doesn't "get through", then I believe you may have your answer. Did you update/check the firmware on the FP?
Also, if possible, take the HDMI cable from the "good" TV with the box in case the HDMI cable on the FP has an impact.
Here are my comments regarding long HDMI cables.
1. You need to get the largest (thickest) gauge cable possible for long lengths. For example, my 25' cable, purchased 11 years ago, is 22 AWG. I'm currently only running 1080P through that cable.
2. The other option is to use something like Redmere technology to overcome long distance cable issues. That information is several years old though and I've not been keeping up on whether they work for the latest 4K.
3. I assume you're normally going through an AVR or other device. Have you connected the Rogers box directly to the long cable, rather than going through the AVR?
4. Some cables, like Redmere are directional and only work properly "one way".
5. The Bluerigger cable says it's capable of 4K, so you'd think it would "easily" handle 1080P signals...?
6. The gauge of the Bluerigger cable is apparently only 26 AWG. Not a good sign.
7. Try unplugging and replugging the cable at both ends a couple of times in case there's any oxidation on the contacts causing issues.
8. I just read some reviews (Q&As on the Amazon website) and people had some issues with Bluerigger cables over 25'. Apparently the "specs" for these cables are based on a maximum 25'. These issues were sometimes overcome by using redmere, or a separate HDMI signal booster. The location of the booster is important and is often counter-intuitive.
Good Luck.
1. A booster is usually placed close to the TV/FP, so you'd have your existing cable, then the booster, which requires power of some sort, then a short cable to the TV. All would need to meet whatever spec you're trying to send, 4K, etc.
2. If the Redmere cable meets all the specs, then there is no need for a booster since the booster is built into Redmere and that's why the cable can be thinner. Redmere, or similar cables are one-directional.
