There's probably not that much you can do in terms of latency.

 

Internet shouldn't come into play at all, unless the computer and screen are located in different homes. Otherwise it's all local network/Wi-Fi.

 

Reduced resolution will reduce the bandwidth requirement, but bandwidth and latency are not directly related. Lower resolution could potentially mean less time spent encoding/compressing which might help with latency if you're lucky. But otherwise latency is all about physical distance.

 

Best bet for an external screen is an actual screen connected through DP or HDMI. Anything wireless will have these limitations.

I am currently using my Lenovo Ideapad Pro 5 14APH8 laptop as a wireless display for my computer, both on the same network with a 900UP 900 down connection, computer is wired, laptop is wireless on the network.

I am using the laptop as a second screen but I am finding problems with stability and image quality, I am using the windows wireless display utility

The laptop screen is 2880x1800 120hz, but in the wireless mode if I choose the highest res I can only do 30hz, but if I go under 1080p I can do 60hz on the laptop display.

Is there anyway I can use full native res and 120hz?

And sometime after 4 hours the wireless utility just turns off needing me to connect the screen again which is really annoying when I am in the middle of a good gta speedrun.
Is there a way I could connect the laptop to the PC wired and just have a perfect no loss connection?

Use an HDMI cable to connect the laptop to the desktop computer and use the same method you used when you connected it wirelessly. Windows should autodetect it.

I have just tried this, with connecting the both devices with a HDMI cable, still only allows me to use 60HZ at 1050p resolution, there is still a huge input delay when I use the second screen so I am not sure if the cable is doing anything?

You should be able to change both the resolution and the refresh rate thru the settings menu.

Depending on the GPU NVIDIA and Intel both have their own Graphics Control programs, I believe AMD does also, but I'm not 100% sure.

 

At any rate both monitors can have different resolutions and refresh rates and work together.

HDMI is unidirectional. You can't send video into a laptop and have it display.

Unlikely. This would require a lot more bandwidth, which probably exceeds what is available wirelessly, even with compression.

 

2880x1800x30Hz -> 3.89 Gbps

1920x1080x60Hz -> 3.20 Gbps

 

Full resolution and refresh rate would have an uncompressed data rate of 16.25 Gbps.

So what should I be using? I do find that going with something that requires a high bandwidth does just me a good 1 second or more input delay.
I did think having a good internet would just make that not matter 
So does that mean if I go for example 720p 60hz would that just make the connection better and have less like to drop out?
