1440p on a 4k TV

[Talal86]

Since the current gen nvidia cards are impossible to find at MSRP. I’m thinking of buying an AMD GPU (Rx 9070 TX to be specific)

the card seems to perform fine for my use, 4k/60+ in many modern games, without relying on FSR. also without Ray Tracing as it tanks performance, but that’s not a big deal for me

Saying that, it still struggles with some demanding games, mostly Unreal Engine 5 games (Silent Hill 2, Black Myth Wukong, Alan Wake 2, etc..), so in some cases I’ll have to drop the resolution to 1440p

so my question is, would games look noticeably worse running at 1440p on a 77” 4k tv without upscaling from the source?

I know I can use FSR for demanding games, but I’d prefer a native/stable approach

Hard to say. I think the main visual issue might be the need for some type of AA. I use a 27" on my PC at 1440 and never us any type of AA. I'm one of those that don't apply filters to retro games. I love pixels as sharp as possible. At that 77" size at 1440 you may be bothered by aliasing and need to use some kind of AA on your titles.

For my pc using a 4070 laptop GPU, setting system resolution to 4K and adjusting resolution in game looked fine but performance was crap. What worked better for me was setting a lower resolution at the system level, then I could avoid using GPU upscalers/DRS and frame gen while keeping performance solid and FPS above 60. Basically I'm happy with my PC performing more like a PS4 Pro/Xbox One X.

I assume this means the display (LG OLED) is doing the final upscale to 4K, but it looks fine. 1080p was clearer was clearer than 1440p, and it allowed me to turn on more advanced graphics features like ray tracing.

The benchmarks I’ve watched usually used Ultra/Max graphics presets which included AA

1080p clearer than 2k? How come?

Integer scaling looks cleaner. When you scale from 1080p to 4K, that 2x upscale makes every 1080p pixel occupies 4 pixels at 2160p. 1440p looks softer when it scales up to 2160p since it is a multiple of 1.5, but you can get more detail so it’s a bit of a trade off. Since I can also push more frames at the lower resolution, it’s a better choice for me.

Right, integer scaling is another option I could try

Never mind, this $600 card is $1000 everywhere..

I've got a dated PC at this point and my 2080ti doesn't even output 2160 120hz over HDMI. So once I had the ability to use 1440 120hz on my 77" LG c2 I've been super happy with it

well, got a 4080.. will still need to choose between 1440p or enable DLSS for Unreal Engine 5 games, but for the majority of games I can do native 4k/60+

went with a 40-series card so I don’t lose the 32-bit physX support

Nice!

Might be worth starting with the Nvidia app, select your game and let it apply the optimal settings and go from there. Personally I'd rather get pure performance w/o upscaling and/or frame gen so I'm ok with lowering the resolution a bit and then adjusting the sliders that are important to me.

To answer my question, 1440p on a 4k tv looks like 1440p lol

which is a very good resolution btw. I guess all of what I read about how crucial upscaling is and how bad going below native resolution on PC, is just nonsense.

I'm playing Robocop which can't run 4k with a locked 60fps on my pc, so I tried to use DLSS quality (upscaled 4k), and also tried to lower the resolution to 1440p, and I found both to look pretty similar

if anything 1440p is better because it's more stable, as DLSS introduced minor flickering to the textures in the close-up conversation scenes.
