If you own a Viewsonic projector, you probably already know what a great piece of technology it is!
Viewsonic projectors allow you to plug and play – all you need to do is connect the projector to a laptop. Most times, it will even automatically adjust to the best resolution.
However, sometimes the video resolution won’t automatically adjust, leaving you with less than ideal video quality in your projected image.
When that happens, you need to change the resolution on the Viewsonic projector by yourself. But how do you do that?

Materials You Will Need
Before starting, you will need some basic materials for your setup.
First, you will (obviously) need your Viewsonic projector and any kind of User Manual or User Guide that came with it.
Second, you will need a laptop from which you will be projecting the image or video.
Third, you will need a projector screen . You can always use a blank, white wall with no objects or markings if you don’t have one.
Finally, you will need the appropriate cables to connect everything. These are the video cables, audio cables, and power cables.
Once you’ve got everything together, you can follow our guide below!
How to Change Resolution on Viewsonic Projector?
To change the resolution on a Viewsonic projector, you will need to follow seven steps, all of which we’ve outlined below.
Step 1: Plug and Turn On Your Viewsonic Projector
First things first!
Take the power cable of your Viewsonic projector and connect it to an outlet.
Once everything is connected securely, turn on your projector.
Step 2: Connect Your Viewsonic Projector to Your Laptop
Take the appropriate video cable and use it to connect your Viewsonic projector to your laptop.
The most convenient cable would be an HDMI cable since it can carry video and audio.
But if your Viewsonic projector is an older model, you will most likely have to use a VGA cable for the video connection and a separate audio cable for the sound.
Ensure everything is plugged in well and that no cables are damaged or fraying before proceeding to the next step.
Step 3: Test Your Setup
Before fiddling with the resolution settings, you must test your setup.
On your laptop, go to your Display Properties. From there, you should be able to see which display devices are connected to your laptop.
If your Viewsonic projector doesn’t show up, you will have to reconnect it or use different cables.
If it does show up, test your setup by projecting something.
Most laptops should have options to either mirror your display or extend it using your Viewsonic projector.
For example, for Windows, you can press the Windows + P buttons to prompt the projector options.
Step 4: Check the Native Resolution of Your Viewsonic Projector
To prevent any issues with the image quality, you first need to check the native maximum resolution on your Viewsonic projector.
You can do this in four ways:
First, you can read the User Guide or Manual that came with your Viewsonic projector. Scan through it for “native resolution” or “maximum resolution.”
Second, you can search the Viewsonic website for the model of your Viewsonic projector. You can find the model number in the User Guide or on your projector. The website should list all of the projector’s specifications, including its native resolution.
Third, you can go straight to the source and check the menu on your Viewsonic projector. Go to the Information section, and look for Resolution. The pixel resolution should be listed there, along with the Hertz.
Fourth, you can use your laptop. Go to Display Properties, and check the details for your Viewsonic projector.
Step 5: Check the Resolution on Your Laptop
To get the best image quality out of your Viewsonic projector, you must match its native resolution on your laptop.
But first, you need to know what resolution your laptop is sending to the projector!
To check the resolution on your laptop:
- Right-click on any open area of your desktop.
- Select Display settings
- Go to your Display settings page.
You should now be able to see the resolution of your display.
The exact steps may differ, depending on what type of laptop you own. But basically, you’ll want to look for your screen resolution settings.
Step 6: Change Your Laptop’s Resolution to Match the Projector’s Resolution
Now that you know the resolution of both your Viewsonic projector and your laptop, you need to match the two resolutions.
To change your laptop’s resolution to match the projector’s resolution:
- Go to your Display settings page
- Click on Display resolution
- Choose the resolution that matches the native resolution of your Viewsonic projector.
- Make sure to save the settings.
Again, the exact steps may differ based on your laptop, but just make sure your laptop’s resolution is the same as (or as close to) your Viewsonic projector’s resolution.
Step 7: Check the Video Quality of Your Projection
You may be tempted to skip this step, but don’t! This step is the final check, and you don’t want to find out you’ve got a glitch when you’re in the middle of watching a movie or doing a presentation.
For this last step, all you need to do is check the video quality of your projection.
Project something using the Mirror or Extend options on your laptop and study the video’s resolution.
You should be able to tell if it looks alright on your own, but here is some general advice: if the image is pixelated or flickering, that is a sign something is wrong.
If issues arise, go back to Step 1 and start the whole process again.
If that still doesn’t work, try contacting Viewsonic and asking for help. You can fill out their customer service form on their website or call them at 800-688-6688
Conclusion
And that is all you need to do to change the resolution on your Viewsonic projector!
