Hi. Just wondering if there are any computer settings that may help me. I have an ASUS Vivobook laptop (Win11, 12th Gen Intel i5-12500H 2.50 GHz, 8GB RAM) bought new in Nov 2022. For the last year, when I cast a movie to Roku, the video will play ok for a little bit but inevitably the picture on the TV will start to pixelate sporadically. I have a Roku 3910RW. WIFI band is 2.4GHz (same network on Roku and Laptop) (BTW, this happens even if I download and save a video on my ASUS laptop first and then try to mirror it....)
Now here's the deal! When I put my old 2016 Microsoft SurfacePro 4 (Win10, Intel i5-6300U 2.40 GHz, 4GB RAM with battery that doesn't last long) in the exact same place on the table in our room as my newer crankin' ASUS laptop, I can mirror just fine for hours with no video pixelating! Now what the heck is that all about?
One would conclude it's got to be something with the ASUS laptop (not the Roku, nor the WIFI signal). I mean, the ASUS connects to the Roku just fine...it's just that repeated pixelating. Please help... Been trying things off and on for a year, but finally thought to post something here in hopes someone smarter than me knows the answer. Thx.
