I used an old dell xps 15 9550 for many years. Will no longer be using it anymore and will be using a new laptop. Had it connected with 2 external monitors... one is 32' 4k monitor via usb-c to displayport cable. The other 24' 1920x1200 monitor I connect it via hdmi to dvi cable.
1. The hdmi port on this xps 15 9550 laptop seem to be 1.4? What is the max resolution I could actually done with the hdmi port? They hdmi port no longer works anymore but could I have done 4k resolution? If so, it would be 30hz correct?
2. I also heard you do not want 4k at 30hz because there is lag... correct? So whether you have 1 external monitor or 2 external monitor, you never want 30hz and always want 60hz? But if you just do basic things, then 30hz isn't an issue? I heard there was some lag with 30hz but that is only if you play games or do something intensive?
3. When I had set up the 2 external monitors, I did this with those 2 cables and no docking station or anything like that. Now i know the 32' 4k monitor was 60hz. But when I am using 1920x1200 resolution on the 24' monitor that is connected from hdmi to dvi, am I getting 60hz or not? I recall it showed that a while back when I checked the monitor settings but I'm not sure. Would it been possible it was 1920x1200 at 30hz? The other thing is if it was 1920x1200 at 30hz, would I notice unbearable lag?
4. So when looking at a laptop, if they mention an hdmi port, make sure it is at least hdmi 2.0 in order for that hdmi port to do 4k resolution at 60hz right? I heard there is hdmi 1.2 and 1.4. So 1.2 can't even do 4k and max is 1920x1080 at 60hz?
5. I notice many dock station or thunderbolt dock or hdmi adapters mention how you could get another external monitor but the max resolution might be 1920x1200 at 60hz. Or its 4k at 30hz. Or it could be 4k at 60hz for 1 monitor and 4k at 30hz for dual monitor. So always avoid anything that is 30hz? I am curious how bad 30hz is exactly because i heard people say to avoid it. Is it really bad if you only have 1 external monitor? It is much worst if you have 1 external monitor at 4k 60hz and the second monitor at 4k 30hz?
