I just booted up my new raspberry pi 4B with raspbian buster.
However, the screen size seems to be too large to fit on my tv. I can’t see the task panel (not sure what it’s called) and the icons on the sides are cut off.
Any clue on how to fix that?

OKdo 5.1V 3A power supply
Latest Raspbian Buster

Probably the known "overscan" issue - historically T.V.'s always expected an overscanned input, however some (recent) T.V.'s (I have some) expect an underscanned input from a "PC-like" connected device but
don't necessarily state that in the edid file. Edid handling changed within Buster and overscan/underscan methods are "in the pipeline" for the P4B. Buster also behaves differently with older Pi's and HDMI-to-VGA converters. AFAICT it's more of an issue for displays (T.V.'s) that only
support CEA modes, DMT modes, either via HDMI/DVI or a (good) HDMI-to-VGA converter behave/are handled better. I haven't re-tested overscan/underscan recently - there may have been an update - it's also needed for composite output. For the P4B, IIRC, it's possible to (partially) revert to "older methods" but, IIRC, that may impact on dual-video output (not something I have need for - no suitable extra displays - and so haven't played with ....)

Still running Raspbian Jessie or Stretch on some older Pi's (an A, B1, B2, B+, P2B, 3xP0, P0W, 2xP3A+, P3B+, P3B, B+, A+ and a B2) but Buster on the P4B's. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm
