You don't even know how big of an upgrade it will be for you, I went from a 10+ year old 19" Packard Bell and the first time I opened Chrome on the Dell the white Google background almost melted my eyes.
When you get it and you YouTube some 4K video which you set to 1080P and make it full screen you will know you made the right decision.
You were 100% right. The monitor is amazing and next to the 2 old ACER's, it makes them look yellow and washed out. So glad I bought this monitor!
