My NUVI 2557 LMT display loses brightness, then becomes bright again every 1-2 minutes. I have fiddled with the setting, time out, color, etc., to no avail.

I've seen mine do that. I think it might have something to do with not using it for a long time. Then if you do somethingwith it, it will go back to full brightness. I supose it has to do with saving battery life. Though running it on the car batterythis wouldn't make much sense. That's the best I can come us with.

I can only see the date for a very short time by pushing the top button. Couldn't find a way to make it stay on. Let me also say that in certain lighting, the display is unreadable.

Based on my experience, the issue is related to how level is you Luma. If it is not level, then it will turn itself off. Try to make it as level as possible and test it again.

Hi, brightness of the display for this Sony Clock Radio has 4 settings - High (default), Middle, Low and Off. Hope this helps. -Ely

I agree it is very dark or dim when I have it plugged in. If I unplug it the screen is very bright. Will contact garmin to see why. Also volume is very low

There is no way to make the display brighter. I have problems seeing it during the day. In fact I can't even tell it's on until it makes a noise. The display works best at night while you just have to listen to the different sounds during the day.

According to UCI (I called them). It will shine/burn for 2 hours @150 Lumens, then it will start to dim and go into power saving mode.

Usually by going to control panel and then display. Could also be a function your power saver mode sometimes reducing the brightness to save power. Jon A

it might be simple as (settings), you can try going to your settings and turn off the auto brightness and adjust the brightness to a full.or it can be a defected parts. always by an OEM parts for replacements.I don't think there is anything wrong with you motherboard.

Try this: go to "settings" (upper-left of the arrows)....use right arrow to get to Brightness, further right arrows to adjust,use OK, then "EXIT".

The dimmest display setting is more dim that my previous clock, but still too bright for me to be happy with. Since I also sleep poorly unless the room is VERY dark, I wear my eye mask and can usually fall asleep this way. My mask falls off while I sleep almost every night, so the brightening light still wakes me in the morning! (For me, this is true about 13/14 nights.) With my old clock, I would layer Kleenex tissues over the display until it was just BARELY visible in the dark. This clock face is too tall for the tissue trick to work, but the orange glow is lighter than my old red display. Good luck!

We have the same problem with our TV. The screen is normally very dim, then gets very bight. We've never had the screen go black. We have also noticed the same phenomenon that J. Wu mentioned about the lamp.Have either of you solved this problem? Were you able to exchange it?

Check your brightness setting. I read that one user was getting flickering when he had the brightness setting set to 75% and CPU usage was high. He didn't see it any other time. Search the net for more info. May or may not be a platform issue.

This seems odd, as I use mine in broad daylight at 50%. Have you checked the display settings? Go to Tools, then Settings, then Display. Do you have the time set up? Need to ensure you are set for daytime.

I have a similar issue. Although it worked fine on Christmas day, batteries lasted for 4 hours only. Put a second set in later the same day. Screen has been flickering ever since. Yesterday, tried to turn it on and blank screen. It is still working as you can tap the screen and it moves on, however, nothing can be seen. After and 10 minutes, it seems to come on but it seems like there is a loose connection in the display. And when connecting via the USB connection, it is not recognising the unit. My problem is that I purchased the unit in US while on a business trip, but live in Ireland! I am going to contact Vtech in the UK to see if they can help. I have a similar issue.

Well I've got the 255W and have tried all of this stuff. It used to display the Garmin logo before turning off completely. Now it is just dead. Pressing any of the corners of the screen while sliding the powers witch for 8, 15, 30 , or even up to a minute. Does absolutely nothing. It has been charged with the provided car charger as well as a USB and still it is stone dead. Judging from my experience and the posts on this thread the 255 is a dud.

Even when the vehicle is not turned on, the digital display stays on if it is plugged into car lighter, but is not bright. When the vehicle is turned on the backlight is bright and very easy to read. I find the orange a little brighter and easier to read.
