Costs a lot less than an iPad, but you get a lot less too--beginning with resolution. But assuming one could live with those constraints, what would the actual utility of the thing be? If, by chance you already have an iPad, there are already several (software) ways to connect it to a laptop for use as an additional or extension screen. Considering the used prices of older iPads, that route could be the best way to go--still, assuming one actually needs that functionality?

RayFI get where you're coming from and totally agree with you about the resolution thing, but have you actually every used these iOS apps? I have tried many of them and they're all terrible. They're fine if you only need something on the screen thats static. The lag is insane! I cant remember exactly what kind of refresh rate you get , but it is very very VERY low. Way lower than 60Hz thats for sure. More like anywhere between 1-30Hz at any given time was my experience. Unless you're willing to sacrifice resolution, which still doesn't help enough to make it actually usable on a regular basis. And that was my (latest experience) on a 12" iPad Pro 2. Even just moving your mouse on the iPad's screen is painful. And the older the pad the worse the problem is (I've been playing with this concept with pretty much every gen of ipad since peeps first started coming out with this kind of app). I still have hope that one of these days it'll get better, but for now it's more of a novelty than anything actually useful.

eneroI'm sure you're right about the weak performance--possibly goes back to my point; if there really was a need for this kind connectivity, one assumes the market would provide a better solution?

RayFTotally. I'm one of those oddballs that has been looking for a small HDMI monitor solution for years and short of insanely overpriced reference monitors theres not a whole lot out there that full my needs and that are reasonably priced. USB Monitors dont work right for me either. Seems like as large monitors fall in price, small monitors go up. Again, I guess because of the lack of demand.

enero@enero have you tried Duet? It works over USB, not wifi, which AFAICT is why the old apps were so shitty (the first one I used was air-something, and it was about the quality that you describe). When I was using it last year it was very responsive and supported the full 2048 x 1536 resolution. I believe it was running at 60hz but it could have been 30. If it was 30 I never noticed when I was scrolling through websites and documentation. It is pretty demanding on your CPU though. You have to pay for the pro but it's reasonably priced for how much better it is than the competition. https://www.duetdisplay.com/pro/ (no affiliation, just a satisfied customer)

internetpartyYeah, Duets the one I have been using lately when I'm on the road and desperate for a 2nd screen. Its the most stable of all the ones Ive tried. But its still incredibly laggy with my MBP tethered to my 12" ipad pro 2. luckily Ive only needed the 2nd screen for either menus or referencing files while I work, so it'll do for now. I dont know what it is, since you dont seem to have a problem. But Ive had the same issues while playing with these apps on both my laptop and desktop machines. Hopefully Apple's own version thats coming out will be better for me.
