Resolved Question

upgrading monitor AND video card

Hardware involved:
Dell XPS 8300, i-7 3.4 Ghz, 12 GB RAM, W7 Pro, AMD Radeon HD 6450
(2) 24" monitors
I want to go to a single 32" Acer higher-resolution monitor, which needs a different video card to get the higher resolution I am seeking. I have the monitor and video card, but cannot get the monitor to display anything when I boot up with new video card in place.
I tried a BioStar 4GB Radeon RX-550 and got nothing, sent it back because I thought it was defective. Now have MSI version of same card, but same result. Clearly I'm doing something wrong.
What do I need to do prior to swapping the video card in order to get a display signal at boot-up? The 32" monitor works fine, but looks mediocre at 1920 x 1080Wink

Wrong video card et al.

Thanks for the succinct analysis. I find it puzzling that hardware like this can have characteristics that are critical to functionality, that are not specifically pointed out in system requirements for the host machine. I normally would have preferred Nvidia in any case, but the monitor specs made mention of Freesync compatibility, which seemed like a decent reason to try the AMD card. As it happens, AMD was also already in the system (Radeon HD6450), but it is incapable of the higher res I'm looking for.

Loks like the A06 BIOS version is it for this machine, according to Dell website. Is there any known UEFI-upgrade path possibility for mere mortals in this case? I looked at your referenced post about the HP upgrade and didn't see anything specific in that regard, I assume because the W10 OS upgrade includes UEFI protocol. I am uninterested in going into W10 on this machine.

The Nvidia you mention are fairly pricey by comparison, I was trying to stay around $100 or a little over. The search goes on, I guess.

Thanks -- bit the bullet

Went ahead with Nvidia 1050 Ti from Amazon, $169. We'll see how that goes. Of course, it's the MSI version which is likely the slowest of the bunch, but I'm not so interested in speed. Thanks for the "actionable intelligence".Wink

Buried in my HP upgrade share was a thing.

It won't affect many but I put it out there since a few may wonder.

The old BIOS can not initialize the GPU for use on DISPLAYPORT. This means that if you need to get to the BIOS or boot many other repair tools you must put the monitor on the other video outputs.

This only applies to the DISPLAYPORT output. After Windows has booted then DISPLAYPORT works but imagine everyday folk. That could really throw them for a loop much like the EUFI and LEGACY BIOS areas.

Sorry if this does not apply to you but I leave breadcrumbs like this so that others that Google may trip over this and find their answer.

PS. Meant to add this compare too.
