Dell Inspiron 2310 W10 does not support Screen duplicate

I have just updated an old Dell Inspiron 2310 all in one touchscreen PC to Windows 10 Pro (it was W7 Pro)
This was an upgrade - not a fresh install.

PC has an ATI Mobility Radeon HD 5470 on board.
It's also using a USB 2 VGA DisplayLink adapter (no name brand) to duplicate the display to a Viewsonic HD projector.
That way the user can use the touchscreen and display the results on the projector (important as Extend screen requires the mouse).
This worked perfectly in Windows 7 (the screen resolution had to be dropped to 1680 x 1050 to accommodate the screen duplication but I suspect this is because they had the Bios VGA memory size set to 512Mb).

I've updated the Bios to A04 and checked that the on board graphics memory is set to max (driver properties now says 1Gb dedicated and 3Gb shared display RAM).
All Windows updates installed.
I've installed the latest DisplayLink VGA driver (Feb 2020)
I've tried every driver I can find for the ATI card (including the Catalyst Beta 15.6 driver, and ATI Autodetect) but the duplicate display function does not work.
It turns off the signal to the projector (and does the same on a HD VGA screen I put in it's place).
I've also tried with the Bios VGA memory set to 512Mb as before.

I can extend the screen (but you lose the touch facility) without a problem.

After much research most people say this issue is caused because the driver is too old to support the W10 DisplayLink duplicate function.
And I cannot find another driver that is newer that supports that old ATI card.

If I disable the ATI driver and install the Microsoft Basic VGA driver instead - I can duplicate the screen but the drivers max res is 1280x1024

So my question is - does anyone know of a newer (possibly generic) driver that would support higher resolutions for the ATI card and support screen duplicate.
Or indeed a newer ATI driver that supports that graphics chip.

I cannot go back to W7 as I've updated an entire classroom of these (19 in total) and this is the only issue we have now.
A fresh install is not really feasible as the user no longer has the installers for some of the older software and I cannot get them from defunct manufacturer.

You'll probably have to replace the USB video adapter with one that supports Windows 10, or maybe even better would be a dual head display card for the desktop that uses the projector.

The newest should be this one:


However, it's only slightly newer, and made for the very first Win10 incarnation. We're now 4 years further, with the chip already being 10 years old. I do not see a bright future for this combination to get it to work as you wish.

I'll try it...
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

Sorry - does not work.
That download installs the Catalyst Manager (no driver) that then installs the same 2015 HD5000 series driver.

Brian B - this is an all in one PC - essentially a laptop motherboard with the graphics chip on the motherboard.
No slots to fit another card.
The USB adapter supports Windows 10 - all external discussions point to the driver being too old.
Indeed in my post I said if I uninstall the ATI driver (not the USB one) I can duplicate the display with the Microsoft Basic VGA driver.

Okay thanks for the details. I wasn't sure about the PC model so when I did a quick lookup, I missed the limited expandability.
Having said that, as you said the issue is lack of up to date drivers which jives with my suggestion to get a more up to date video adapter even if it's just USB.

Brain B - it's not the USB adapter that's the issue (I've already tried another) - it's the inbuilt Radeon card that does not have a driver for Win 10 that supports the duplicate screen function.

Interesting solution. Thanks for the update.


Update - there is a new Beta release (9.7Beta) that mirrors the entire screen without titles or borders.
Screen is no longer fuzzy and it's a little quicker too.

Best $29 I've spent and customer is happy with it.
