Not surprising as your display pixel density is around 80ppi and mine is 218ppi - so yours is low resolution and would better suit viewing of low resolution images as it simply doesn't have the ability to display fine detail.
The typical high resolution display would have a pixel density of at least 150ppi. Retina displays typically are over 200 because at that pixel density and at normal viewing distances the eye is unable to discern the individual pixels, so for example text looks completely smooth.
A 4K monitor displays 4K of image detail regardless of the display size, and, consequently, regardless of the display PPI. A large 4K monitor with a lower PPI displays the same amount of image detail as a small 4K monitor with a higher PPI, and if viewing distance is adjusted the angular subtense of pixels is the same.
Visual acuity depends on angles.
For continuous tone images (i.e. photographs), most 4K or higher monitors at normal viewing distance exceed the visual acuity of humans with 20/20 vision.

A quick google search shows 218ppi would be like the iMac 27" 5K monitor. Which I'm guessing puts you in the extreme minority of viewers.
Also, resolution and pixel density are different things. Nobody is calling a 4K monitor low resolution lol. I can also just downsize the image on the monitor to increase the PPI if you think that matters.
How do you suggest people present the images on FM to maximize resolution?

Pixel: This is the smallest building block of your screen. Resolution: This is refers to the size of the pixel. The smaller the pixel, the higher the resolution.
And yep I am calling a 55" 4K monitor low resolution - no different to a 19" 2K monitor from 10 years ago - just physically a much bigger monitor. But then if it were a TV and viewed at TV distances you might consider it to be high resolution when compared to a 55" 2K TV.
Of course you are free to use whatever definitions you choose.
The only way I know of to present images on FM at higher resolution is to post links to images hosted elsewhere.
Personally I use an AWS S3 bucket and post links to the images stored there - AWS S3 storage is relatively inexpensive, a couple of dollars a month for a 100+ GB. Of course you need to know your way around setting up S3 storage.

Australia Sampler 6: Kookaburras
Another iconic Australian bird seen during the trip. Images 1-4 were of the Laughing Kookaburra. Mostly seen perching among branches. Detected one tree with several noisy Kookaburras from one of the spots visited. The BIFs were rather instinctive (just aimed as I detected a movement) as two came from my blind side and even against the light. Had to take the shots as I might not have the chance anymore (so true as limited further flights were quite far or heavily obstructed). Quite passable shots (most likely just documentary BIFs).
Image 5 - Only one Blue Winged Kookaburra (on a wire) seen in Tablelands (near Cairns) and shot taken from the car along the road. Could not stay long.
Images 6-7 - Our veteran guide (Shane from Tropical Birding Australia) made a hard turn upon seeing this along the road. He was quite interested. It was mostly light/dark brown back and breast areas (hybrid? morphed? molting?). We stayed for some minutes placing the car at three different possible angles. As we were about to leave, it flew away. Caught mostly back views from instinctive BIF pan.
