720p is fine for me as well from the couch. At 12ft, 65", WiiU still looks good.
Plus my cable provider is still at 720p / 1080i, still looks good.

So sure, make it 720p on Lockhart. The trick is, 720p scales up very nicely to a 4K tv. 1080p tv not so nicely.
1440p is also 1.5:1 scaling to 4K (same as 720p to 1080p), but since the dpi is much higher it's less of a problem with scaling.
Time for 8K tvs to make 1440p upscaling 3:1 :)

1080P scales perfectly to a 4k TV.

4k is 3840x2160.
1080P is 1920x1080.

You are just quadrupling your pixel counts or doubling on each axis instead of triple with 720P.

Scaling is a tricky and complex issue, mostly due to scalers doing a few passes on an image to clean it up and thus have different effectiveness.

1440P is 2560x1440.
720P is 1280x720.

That is also a quadrupling in pixel counts.

Consoles do the upscaling as well now and can use a lot more temporal information to get great results when upscaling to 4K.
Last gen you had actual 720p output which a 1080p tv would display with overscan.

4K tvs simply triple the pixels per axis (with some smoothing I assume) for 720p while the consoles scale to 4K from variable resolutions for the best result. Hence 1440p to 4K upscale looks much better than last gens 720p to 1080p tv.

It depends on what Lockhart does with the image how good a 720p game will look. I guess there will be plenty options in system settings.
Output 720p for 720p tvs and 4K tvs.
Output 1080p with internal upscale to 1080p for the best results on 1080p tv.
Actually it will probably just use an internal scale for whatever display resolution you connect it to. Less latency if the tv doesn't have to do it.

Last gen the 360 also had an internal scaler but it wasn't that great. I remember setting the output to 720p to get a sharper image on my 1080p projector while playing Alan Wake. With the 360 set to 1080p the image looked slightly worse. Not a fair comparison though, $4000 projector with high end scaling vs a cheap console.



I was a bit obsessed with image quality last gen lol. For example my analysis of 360 vs ps3 output

Standard grey palette from RGB 0,0,0 to 255,255,255 with ps3 set to Full RGB and 360 to Expanded and projector calibrated to use the full range for both. Picture taken with a Nikon D40 (which had a smaller contrast range than the projector but the difference is visible)

The 360 applied a gamma correction to make everything darker. Hence if you calibrated your TV for the 360, ps3 would look washed out. If you calibrated your TV for ps3, 360 suffered from black crush. Calibrating both to make full use of the brightness range, 360 still looks a bit darker overall. (Can't have 128,128,128 at 50% brightness while still having both 0,0,0 and 255,255,255 at black and full white)

Developers had to compensate for that gamma correction. It makes visuals pop more, but black crush destroyed details in darker areas. It was still there at the beginning of this gen with XBox One, dunno if MS has abandoned it now or if developers are still compensating for the gamma correction. I guess it should be gone with HDR. (Seems XBox One still has black crush https://www.reddit.com/r/xboxone/comments/f28gsv/black_crush_is_ruining_the_xbox_one_x_for_me/ https://www.avforums.com/threads/xbox-one-s-black-crush.2126564/)

Leave the display to do the color, brightness and contrast corrections, while the console handles the upscaling.
