Hello!

I bought a Lenovo ThinkVision LT2252p for $2.50 at a garage sale last weekend, and everything works great with it besides one thing, I can't get this message to go away:

"Input Signal Out of Range

Please Change to 1680x1050 @ 60Hz"

I cranked the resolution up to 1920x1080 @ 60Hz, which is the highest this monitor supports, and it is working fine, so I'm not sure why this message is still there. I would appreciate some help. Thanks!

The newer monitors have a limited operation processor that has to boot and like a PC, it has a small battery that holds its configuration when powered off.  When the battery fails, the unit will default to factory settings and   the resulting message.  That's why it was only $2.50.

According to the manual ( https://download.lenovo.com/pccbbs/visuals/lt2252p_ug_eng.pdf ) that monitor is 1680X1050 as it's native resolution so 1920X1080 is "out of range".

That same manual says that you can lock the display to prevent changes by holding down the <-- button for ten seconds and unlock it by doing the same a second time.

(It's on page 2-4 of the manual).

Try the OSD (Onscreen Display) setup and if you find it is locked, unlock it, set the PC to 1680X1050, and see if the message doesn't go away.
