School Vga Projector And New Laptop Issues

My son's a school teacher in CA and bought a new laptop to use in his classes. Details of the new computer:
Comp: HP Envy notebook version 1511 running Windows 10 Home. Graphics card: Intel HD Graphics 520.

This new computer does not have a VGA port and he's been trying to use HDMI with a Belkin VGA to HDMI converter. He has developed PowerPoints with animation using PowerPoint 2016 home and office. They all worked fine with his old computer with a VGA port. But when he uses the new computer with the converter, the screen looks great until he runs the PowerPoint and the PowerPoint display is about half the size of the screen. He's tried to run them in Full Screen Mode, and has tried to change the resolution but changing it to wide screen distorts the images and 4:3 makes it too small.

The school owns the projector and is not likely to replace it with a newer version for at least ten more years.

Businessmen use the new computers and old projectors so there has to be a way to get the display to be full screen and not distorted but we can't find anything on the internet to come even close.

He's spent a day trying to get it to work when he discovered his first converter was bad, so when he got over that frustration, he ran into this. Any suggestions would be greatly appreciated.

I wrote this under the hardware, thinking it make be the converter or port, but as I read this, it may better fall under the Software. I will not duplicate the post but if you judge it should be there instead, let me know what I need to do.

 

If it is an old projector it may only do 4:3, but your saying it only looks bad with the PowerPoint?
Under SlideShow there is an option to change the resolution, click Set Up slideshow.

 

Thank you Foogoo. I appreciate your time and expertise.

He's tried all the resolution settings in PowerPoint, HP Graphics Control Panel, and on the Projector menu itself. No Joy. The shape changes but it still doesn't go full screen or enlarge big enough for the text to be visible to the entire classroom. In 4:3 mode the PowerPoint slide is virtually square but leaves a large margin around the display box which cannot be enlarged.

I'm open to any other ideas. He's frustrated enough to try most anything. I'll try to get photos to help you see the issue in case, I'm not doing a good job in describing this.

 

Good idea.
Also, if the presentation isn't private/confidential, a link to download it (if it's not too big) will also help.

 

The top image is the real estate used when using the VGA port on his old computer. The bottom image is the real estate of the HDMI port image on hi s new computer. In the top image, he marked the outline of the HDMI border with small blue tape which will reflect the amount of the image real estate lost. Changing the resolution changes the shape of the image but not the surface area. I have the PowerPoint which I need to locate on my NAS and add in the morning. Thanks for working this issue.

 

I think this will provide you a sample of the PowerPoint, http://keeferfamily.mydlinkcloud.com/app/websharepro/share/Election Timeline and Superdelegates/

 

The PowerPoint Show itself seems fine.
Under Design > Page Setup, I changed 4:3 t0 16:9 and expectedly there's no distortion.
I suggest he changes the resolution under Slideshow > Monitors.

 

Thanks for the response but it didn't work the image it still much smaller than before.

 

VGA and HDMI are different technologies. Converting from one to the other doesn't always work. The new and the old computers have different hardware. And if the old PC didn't run Windows 10, that could also be a factor.

Is it not possible to ask these people?

 

Eldon, Thank you for you reply.

I found a solution. Not that I know why it works only that it does. I had purchased an adapter a while ago, https://www.amazon.com/VicTsing-Gold-Plated-Converter-Adapter-Desktop/dp/B016HL4CAY. It is a Vic T sin Gold Plated HDMI to VGA adapter/converter. When we plugged it in, it worked great as the new monitor. A couple of adjustments on the graphic settings and it worked perfectly.

I don't know what the difference is between the two adapters he tried, but this works. I'll gladly entertain a class on adapters if some (much smarter than me) can tell me why this one worked and the other didn't.

 

Good to know it's working.
Adapters are a hit or miss affair - especially when different technologies are involved. And more expensive adapters aren't always guaranteed to work.

FWIW Years ago a friend used a parallel to usb adapter. Turning off the laptop meant the printer had to be re-installed - everytime!

 

It's all about what codecs and scaling engine are being used by the company who made the particular adapter.

Some cover all the bases, some leave things to be desired...
