Mouse doesn't feel right

[venomx]

Have a spare 43" LG UHD TV lying around so thought i'd see if I can connect it to my PC for gaming.
Everything seems fine however the mouse doesn't feel right ? It's not as precise and is slightly laggy.

Is there some settings I can change to adjust this ?. Mouse is a Logitech G305.

After adjusting some settings and the DPI in the mouse it's a bit better

It might be the TV being laggy and why it doesnt feel right

Just changed it to Game mode and now it's perfect ! 43" UHD screen ftw
