LG monitor secret menu- Panel name??

itsakjt · Apr 13, 2013

So I found the way to enter LG monitor service menu. Just turn off the monitor, wait for 5 seconds. Then press and hold the menu button. With it pressed, press the power button. The monitor will be on. Release menu button. Then press menu again and you will get the secret menu.
So this way, I found a field called "Panel" and in my LG E2042TC, it is written CMI 200 L23. I immediately searched Google and came to know that the panel is manufactured by Cheimei Innolux corporation- Taiwan's largest LCD manufacturer and the world's second largest(as per wiki). So how is this CMI brand? Any ideas?

Made In Taiwan?

My first idea is to use the monitor as instructed by any distributor and use the super-secret menu for diagnostic/benchmark purposes

My second idea is to dance, inspired by your avatar:

Just done this on my LG ISP277L. You have to hold the menu button and then power on, then hit menu again.

IPS277L
NT68753 ver 1.71
120114 MNTSW ETI. 79

Clear ETI > no
Auto color > no
Aging >no
Panel >LGD270wf5
NVRAM INIT >no
HPD > 500

Mine seems to be an LG factory panel.

It seems for the expensive models, LG uses their own panels only.

My old W1943S cost more than my present E2042TC and the W1943 used a LG original panel but the present one uses CMI panel.

Yes, I remember on my old 22" LG you could actually change the panel name and get a better picture. I don't remember what I did exactly because it was years ago now, but on Oblivion game I was getting shadowing with certain colors at night-time during the game. I changed the panel name through that secret menu and the problem was solved.

Did you try the init NVRAM option? Open the service menu and scroll to the init NVRAM option. Then press and hold the button with which the values are changed for a few seconds. The display will go off and the monitor will be reset to factory values. Before doing it, just keep a note of your panel name and change any settings required.

Thank you so, so much!

This also works for the much more recent UltraGear 27GL83A.
Only difference is (because it only has the joystick) that one needs to scroll down to the NVRAM option and push the joystick to the right for a few seconds. Hope this helps some poor soul in the future, just like your comment helped me :toast:
