Jean Fallon is concerned about overusing a Nexus 10 display:

I just bought a Nexus 10 and connect it to my TV to enjoy content displayed on the larger screen. I leave the tablet running for hours on end and get a bit worried about leaving the screen running for so long. I searched online for an application to switch off the screen without the device going on standby, but I haven’t had any luck. The only app I found works on a rooted device but I would prefer not to root my Android tablet. Is there anything at all I can do? How has nobody created such an app yet? I would be happy to pay for it.

Nexus 10 Display Versus Nexus 7 Display

Is It Okay to Keep My Nexus 10 Display on All Day?This is a tough one to answer, Jean, but I’ll do my best. The Nexus 10 was built for a variety of uses, including the ability to mirror its display to an HDTV. That said, it’s unclear whether the Nexus 10 display was made to withstand such prolonged use as you’ve described. If you’re concerned about any image retention issues you may experience, there hasn’t been any widespread reporting of “ghosting” with the 10″ version of the Nexus. In the case of the Nexus 10’s predecessor, the Asus-built Nexus 7, “ghosting” was reported even before the device hit store shelves. The Samsung-built Nexus 10, on the other hand, doesn’t seem to have the same issue.

Nexus 10 and Heat

If you’re concerned more about your Nexus 10 getting too hot, you might want to compare your own experience with others who have reported their 10s to be running hot. Some have reported the tablet only to run hot while playing games but not while watching videos. If you’re finding your device seems to run hotter than others have reported, it may be time to exercise your warranty to see if a replacement unit remains cooling while connected to your television.

Dimming Your Nexus 10 Display

There are some apps that will help you to manage your screen’s brightness in order to use less power, and you might find these help keep your tablet cooler as well. The best apps I’ve come across are Screen Dim, Lux Auto Brightness, Screen Adjuster, and Screen Filter, all of which you’ll find in Google Play. Try the free or trial versions of these apps to see if any of them meet your needs. The developer of Lux Auto Brightness actually wants you to try out the app for longer than Google’s own return period, stating on the app’s Overview page on Google Play that “you can request a refund at any time via e-mail — no questions asked.”

When it comes down to it, some devices runner hotter than others. Now, this could indicate poor manufacturing, but it could also be a sign of the consumer using a device in an unexpected way. If you’re finding your Nexus 10 to be uncomfortably hot while mirroring its output to a TV, my best suggestion is to exchange the device if you’ve got a warranty. If that’s not an option, then try a few of the apps I’ve noted. If you’re still concerned about your Nexus 10’s display, you might want to simply run it for shorter periods of time each day.

If anyone else has a suggestion for Jean, please chime in. Let’s not leave a member of our community in the dark!
