Resolution has changed...how do I get it back?

[budwha]

I am very new and still learning…yesterday I entered display_rotate=1 in config,txt file to see if I could rotate the display(just to see if I could)…it worked so then I deleted it and shutdown the pi. Today when I boot the pi its resolution is changed and the fonts are all too big in the pi desktop and the Magic Mirror. All I did was add rotate and remove it. Here is my config.txt

#hdmi_mode=3

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

# Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on

# Uncomment this to enable the lirc-rpi module
#dtoverlay=lirc-rpi

# Additional overlays and parameters are documented /boot/overlays/README

# Enable audio (loads snd_bcm2835)
dtparam=audio=on

# NOOBS Auto-generated Settings:
#hdmi_force_hotplug=1

Is this the entire config.txt? I can’t see your rotate entry

In pi desktop select start menu -> Preferences -> Raspberry Pi Configuration and set your resolution again.
