It sounds like the resolution in the display settings may be too low.  Assuming that the new TV is 4k, you might check that the resolution is set to 4096x2160, or somethin similar.  I have a 50" 4k tv and have the resolution set to 4096x2180 and also set the display scaling to 150%, to make the text about the right size.  What model is the tv?

Matt is on the right track. This is almost certainly a Windows display resolution and scaling issue, not an Access problem.

First, right-click the desktop and go to Display Settings. Make sure the resolution is set to the TV's recommended/native resolution. For most 4K TVs, that will be 3840 x 2160. Some TVs may report 4096 x 2160, but 3840 x 2160 is the normal consumer 4K resolution.

Then adjust Scale under "Scale and layout." Try 100% first. If everything is too small at the proper resolution, increase it gradually to 125% or 150%. If the resolution is set too low, Access forms will look huge because Windows has fewer pixels available to display them.

Also check the TV's own picture settings. Look for something like PC Mode, Just Scan, Screen Fit, 1:1 Pixel Mapping, or Overscan. TVs often enlarge the image slightly by default to hide the edges of a broadcast signal, which is fine for television but terrible for a computer desktop. You want it displaying every pixel without zooming.

A regular computer monitor is generally better for Access work because the text is usually sharper, the input lag is lower, and it is designed for sitting close to. But a Smart TV can work perfectly well if it has a good native resolution and you get the Windows and TV settings configured correctly.

Additionally, if the tv has a chroma 4:4:4 signal, it has no color compression.  This is what you want for text.  That is why I was asking about the model number.  I learned this the hard way on my last monitor.  It wasn't terrible but it was annoying.

Thank you all for your help with this issue. I have resolved the problem. I have or will find another use for the smart TV. I now have just a regular 32" Computer Monitor. Everything is fine again. Back to normal!
