Devo 10 display refresh rate... Issue?

Hey guys, picked up a lightly used Devo 10 (revision 2?) on RCGroups.

Coming from an old Hitec Flash 5 and have been out of the hobby for a few years so sorry if I'm a bit rusty.

The TX seems great, but question about the display. The update/refresh rate seems very slow on mine, see this video:


Also, a strange line through the USB logo and seems to be missing a pixel.
Running Deviation 4.0.1 that was installed by previous owner.

I do see the latest build (still 4.0.1 though?) for the 10 is dated Jan 3rd.
Should I go through the trouble of trying to install that to see if it fixes?

The display on the Devo10 in fact is slow. Try to adjust contrast to see if that solves your problem. "Strange line" ist just a cosmetic issue, doesn't affect function. Why don't you use the USB menu option? Does the same without pixel artifacts...

Great, thanks for the reply!
