Just bought a 27" Samsung 1440p, and with HDMI I'm only getting 1920x1080, not 2560x1440p.

It's a ATI 5450. I've reinstalled GPU drivers but it's not working at native. What suitable GPU's for HTPC will drive this display over HDMI? I want a silent passive model.

I've tried HDMI-HDMI and DVI-HDMI and no luck just 1920x1080.

I looked at Radeon HD 5450 spec, it supported HDMI only up to 1920x1200.

Is your Radeon HD 5450 a low profile card?

My basket at Overclockers UK:
Total: £73.69 (includes shipping: £8.70)

yeah 5450 is low profile but case is big enough for a large GPU. I managed to get 1920x1200 working DVI-HDMI, so I guess that explains it. Anything a bit cheaper, it's not for gaming. I would prefer ATI due to freesync, if HDMI works over freesync, also I do prefer ATI PQ for video last time I had Nvidia it just seemed blurry for video.
 
Looks like you will need a gpu with either HDMI 1.4 or above or 1x DisplayPort 1.4, You'd need an HDMI 1.4 or newer in order to have 60Hz 1440p support. Only HDMI 2.0 and DisplayPort are capable of 144Hz

Wow you bought very expensive Freesync and Freesync 2 monitor for HD 5450 that did not supported Freesync.

Accorded to HD 5450 spec, it supported dual DVI up to 2560x1600, HDMI up to 1920x1200, DisplayPort up to 2560x1600 and VGA up to 2560x1600.

Your monitor has both HDMI and DisplayPort ports, do you have a DisplayPort cable? Your HD 5450 support 2560x1600 with DisplayPort cable so you don't have to buy a new GPU.
 
The gaming rig is ATI RX 480, Intel xeon 6 core, 24GB RAM, display port, running 2560x1440, 144hz, freesync

The desktop PC is just for browsing watching videos so no need for a top end GPU, basically just need 2560x1440. H265 hardware acceleration would be good though.

You don't have much choice, the only choice is GT 1030 if you want low profile, silent and H265 hardware acceleration.

It sound like your last NVidia card was faulty, it should never have blurred video picture quality. I never had these issue before on all NVidia cards and Intel iGPUs but had problems with 1 AMD card once HD 4870 caused so many issues with image quality washed out in games, poor games performance and worst drivers after many cleaned installed Windows didn't fixed it and RMAed it and OCUK refunded it after tested it as faulty.
 
Nah just seemed for video nvidia lacked IQ. This was well known back then back in day if mpeg from dvds early htpc, also VGA out in ATI was far superior. Remember changing from nvidia to ATI and desktop text was so much better, svga monitors.

Yeah that was very long time ago when ATI's image quality on SVGA monitors was superior to Nvidia but Nvidia caught up to matched ATI image quality in videos few years later.

So that is irreverent now as everybody has HDMI HDTVs and monitors with up to 4K resolution, many are watching 4K Ultra HD Blu-ray or 4K HDR Netflix on either Intel iGPUs and Kaby Lake/Coffee Lake CPU or Nvidia Pascal GPUs but AMD GPUs still do not supported 4K Netflix in driver. Also HDMI 2.1 will be unveiled at CES 2018 in next few days would see the end of Freesync and GSync as all manufacturers will use HDMI 2.1 with VRR instead and Xbox One X supported both Freesync and HDMI 2.1 with VRR.

Also MPEG will soon irreverent in next few months in 2018 when AV1 codec is ready and everybody will use AV1 for free with no royalty fee rather than pay greedy MPEG LA royalty fee for MPEG2, MPEG4 and HEVC every year since 1996 when cable TV and movies studios switched to MPEG2 for broadcast and DVDs. Hopefully all cable TV providers and TV studios will have freedom and bandwidth to switch from MPEG2 and MPEG4 to AV1 encoded 4K on every TV channels in a few years time.
