My projector is BenQ TK-800. When I tried to lower target peak nits below 100 nits, madVR defaults back to 200 nits but anything above 100 nits is settable. Anyone had this type of issue or just me? BTW, I get perfect picture quality at 100 nits, just wanted to do more experimenting.Thanks!

Below 100 nits is not very reasonable, 100 nits is SDR's peak so trying to map to a peak below that gets odd. This behavior is by design, notice that when you type in a number below 100 it is red, while at 100+ it is green.

Do you use a 23 Hz mode of any kind (standard or optimized)? Other refresh rates than 23 Hz don't have problems in short intervalls of frame drops or repeats, as far as I know.
No, I just use 100 (25*4) and 119 Hz (23,976*5). Since this is a PC monitor, I don't like lower refresh rates because of sluggish mouse movement etc.

Guys, for scaling factor 1.3 what do you recommend? Image upscaling: Jinc+upscaling refinement (crispen edges or adaptive sharpening), or image doubling: NGU Sharp medium or high?

Go for NGU if you can afford it.

I can afford NGU Sharp High, but my thought is - is it worth the gpu load...

I'm a huge NGU fan.

For < 1080p files, NGU makes a huge difference even at a distance.

For >= 1080p files, If you're sitting < 5 feet from the monitor/ tv . NGU still looks sharper.

However, for > 5 feet, It's almost impossible to tell NGU vs Nearest neighbor (1080 to 4K) unless you're running a test pattern.

And I tested myself for NGU vs Lanc (1080 to 4K) @ 5 feet, I got it wrong 50% of the time, So I definitely can not tell at that distance for 1080p files. ESPECIALLY for moving image,

Overall, my point is, DO consider being green when possible. Lanc looks very good at 5+ feet.

I agree for a ratio of 1.3x. At that low of an upscale NGU+SSIM100 v.s. Jinc or Lanczos is very subtle in almost all viewing conditions. NGU is only useful for ratios below 1.5x when you use electric heat anyway.

@Siso was asking for scaling factor 1.3, Nearest neighbor for integer scaling is a complete different story.
Anyway if you have to ask here then NGU is probably not worth it? You have to test it, because differences depend on your content and then decide on your own.

I'm watching 1080p good encodes on the monitor which is 21:9 (2560x1080p) I can manage NGU Sharp High with my GTX 1050ti, but I was wondering if I can use image upscaling settings instead of image doubling. The visual difference is not that obvious between them.

Of course you can. I am using Jinc/DXVA upscaling most of the time and „NGU high quality settings“ for a special movies night.

NGU High is good, but does it really need the ~24 ms rendering time on my card...

What sort of question is that? Take it or leave it.
Change chroma or drop back a notch if 24ms is "too high" for you.

If you're on the small screen yes, because you're really close.

On 1080 to 4K from 5 feet w/ a 40-60 inch, it's very hard to tell between Nearest and NGU (highest), Nearly impossible to tell between NGU and Lanc

I think he means, is the visual improvement worth the Processing Effort.

I've not seen one comment on here protesting it ever.
It's his decision to make is he seriously just ticking things and saying "is this good?" He's been on this forum for quite a while.. Anyone would think this was a new account.

I see nothing wrong asking other forum members for their opinion.

This chart appears to be fairly reliable and is probably a good guide for perceived resolution:
