Glare on the 17 inch center console screen

Glare on the 17 inch center console screen

Sorry if this subject has been posted before. Has anyone tried to work on the center console while there is sunlight on the screen? Concerned that it will be just like an Ipad in the sun--almost impossible to see. Any feedback?

Well maybe we'll get some feedback on this once people do the test drives. Unless the test drive courses were carefully designed to avoid it, with all of the different locations and times, there's bound to be at least one point where the sun shines through the side windows onto the screen while someone is test driving.

Hopefully, it's a forum member who can post their observations.

I don't expect their to be glare from light through the pano roof given the tinting, but I do think it's possible from low angle sunlight through the side windows. I'm thinking that the most critical screen (in terms of driving and safety) is the guages screen, and it should be mostly shieled from glare, though it's not set back that deep...

This is something I will definitely look out for on my test drive if I do get to do one. I'm not sure. My reservation number is nearly 5,700. So I'm hoping that I'll be able to do a test drive when they come to Seattle, but I'm prepared for the liklihood that I won't get a slot.

I think it is likely you will have a chance to test drive in Seattle. 1400 people who just had to get their drive and see all 10 colors will have had the opportunity by then. Today's inside tesla left me with the impression that they will not have all 10 cars here, so most test drivers will likely be more local.

If you cannot get a slot, email me at Perhaps you can at least ride along on my drive.

Still, all things considered, I would expect the Bellevue store would have a test drive car available on a regular basis before you have to commit.

Wow, that's very nice of you to offer. I'll keep that in mind.

To be honest, unless I hear some horrible stories, I don't really think I need the test drive to commit. Since there's so many people ahead of me, I'm sure I'll hear about every possible negative and positve aspect of driving and owning the car before it comes time for me to order. It's true, test driving the car would help me be 100% confident in my decision. It's always possible that there might be something about the drive that would make me feel like I couldn't live with the car. You know, there might be something that's not necessarily wrong, but just doesn't suit my taste or maybe it's possible that the car won't fit me properly and driving will be uncomfortable, etc.

But to be honest, if I don't get to test drive the car, it's not going to stop me from ordering. The only thing that would stop me from ordering at this point is some significantly negative news or opinions from actual owners or some kind of personal financial disaster.

The screen is mounted at a fairly strong angle. Looking at some photos it seems like the sun would have to be something like 40 degrees above the horizon for the glare to be a problem... But the roof may block the light at that angle. Perhaps it can be calculated from design drawings?

A simple test can be done with a strong flashlight in a car, and the test would actually be easier to do indoors at any Tesla store: Shine the flashlight at the screen from where your eyes would normally be when driving, and see where the reflection goes... (You might need an assistant.) Does it hit just inside the rear right door on the roof, or does it somehow make it through a window? That's where the sun would have to be to cause glare.

Then try to get your test drive at the time the sun is at that angle? Or ask someone with that time slot to report back on it?

lol, I'll try to remember to take a flashlight.

My test drive is scheduled for 2-3pm anyhow, so regular sunlight should be plentiful.

Smart! "A Candle to Light the Sun" principle.

I asked this a rep at the geneva autosalon and he told me, that it wil be no problem. The screen is designed and placed to have best comfort and not been influenced by the sun

Brian H | 20 juin 2012

Elon also noted that since the screen has (relative to e.g iPad screens) unlimited power available to drive it, it can be as bright as necessary to work in daylight.

Teoatawki | 20 juin 2012

Some people seemed unhappy the screen was somewhat turned toward the driver. But that should prevent the horrible glare problem the guy who did the Karma video review complained about.

Shine the flashlight at the screen from where your eyes would normally be when driving, and see where the reflection goes... (You might need an assistant.) (EdG)

Thinking about it... It may actually be possible to gather the same information without a flashlight (and an assistant). Assuming that the screen, when turned off (dark/black), shows a mirror image, what you see in the "mirror" (while placed in the driver's seat in a normal position) shows where the sun would have to be to cause glare. So, if you cannot see a side window in the "mirror" which is your 17" screen, you should be pretty safe.

Again, that's probably easier to evaluate indoors.

EdG | 20 juin 2012

If you're in a Model S outdoors during the day, just look at the screen from the driver's position and focus your eyes on the reflection and see what's there. Moving your head to dramatically different positions and/or shutting down the 17" screen would probably help see whether you can see a window.

I am puzzled by some of the comments about where the sun has to be to cause glare. I am not attempting to be argumentative with other forum participants but isn't it true that glare off a monitor is not simply angle of incidence equals angle of reflection? Doesn't it also occur from a scattering of light rays in multiple directions by the surface of the monitor? It seems that the sun does not necessarily need to be visible as in a mirror for glare to occur. It also depends on how much the surface of the monitor scatters and/or attenuates incident light. Is this not the experience of others also? Perhaps there are no simple tests and some empirical observations in different lighting situations may be needed to fully resolve the glare question.

EdG | 20 juin 2012

By far the brightest light to hit the interior of the car would be sunlight. A blue day lit sky is bright, too, but the best test would be the sun. Any angle you can see daylight would also be an angle from which you could see the sun (if the car was turning in a circle).

Timo | 20 juin 2012

I think angle of reflection is not the major problem, for some monitors it is enough that Sun shines to the monitor to make them basically unreadable. Some other monitors you can see just fine barring some dust (and fingerprints). Variance is huge. I don't think Tesla uses some useless iPad screens in there (I don't thing there is 17 inch iPads).

You would need to keep it clean though, dust and fingerprints can make monitor look nasty very fast in direct Sunlight.

Brian H | 20 juin 2012

Yes, the screen surface must be as close to perfectly transparent as possible, and the elements non-reflective & non-scattering. Does anyone have a mobile phone or tablet readable in direct sunlight? That's where the battery power comes in, providing contrast and brightness. (Any screen techs here? I've long understood that screen controls for 'brightness' actually control contrast, and vice versa.)
