New GPU

[hornetstinger]

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.

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.

but I'm using DVI to HDMI cable, surely DVI output supports 2450x1440?

• Integrated dual-link DVI output with HDCP11

• Max resolution: 2560x160012

 

[hornetstinger]

I guess DVI dual link to HDMI does not exist?

yeah I'm getting 144hz 2560x1440 from ATI RX480 over DP no problem.

 

[hornetstinger]

no, it's amd x2.

It's for two systems, one is gaming rig (480) the other is quiet desktop PC (5450) guess I need to replace the 5450.

 

[hornetstinger]

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.

 

[hornetstinger]

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.

 

[hornetstinger]

One small question. How are the billions of existing devices going to suddenly sprout AV1 hardware support overnight?

yeah that's the thing, people aren't going to be replacing mobile phones, tablets, GPU's, TV boxes whenever a new codec comes out.

Just went for a MSI 1030 GT, it's the taller one with a large heatsink.

 

[hornetstinger]

Nvidia 1030 GT arrived. Couldn't get 2560x1440 over DVI-HDMI cable, but HDMI-HDMI worked at 2560x1440.

I can't get 144hz to work though. 120hz is ok. Using the supplied HDMI cable with the monitor.

Got it working by creating a custom resolution. Strange I had to do that.

 

[hornetstinger]

DVI to HDMI cable will be single link, therefore limited to ~ 1920x1200...

I could only get 1920x1080 from the DVI-HDMI cable.

Only getting PCI-E x4. Motherboard is a GA-870A-UD3

[hornetstinger]

Not too bad, a little blurry, but fonts are bigger. So scaled from 1920x1090 to 2560x1440.

It's working at 2560x1440 now though, for the Nvidia 1030 and ATI 480. Freesync monitor. 480 is gaming PC, 1030 is HTPC.

 

[hornetstinger]

Pretty suprised a modern GPU is 4X, even though it's 16X length slot. Won't make any difference in performance?

 

[hornetstinger]

It's a PCI-E 2.0 motherboard.

It's really sluggish going into Nvidia control panel, and sometimes a bit sluggish scrolling in firefox.
