why 720p looks so bad on pg278q?

[tigerman]

just got asus pg278q
as i play a lot of 3d games i was thinking about playing some heavy gpu games at 720p, i prefer to have a constant 60fps at 720p instead of 30 at native resolution.
as 720p is exactly half of the monitor resolution i don't understand why there is that ugly gpu upscale to get full screen, is there a way to play fullscreen 720p without gpu upscale ?
in other words, if i put 720 1 pixel should replicated exactly for 4 pixels without any upscale processing by the gpu, any chance?

720p on this monitor should have the same sharpness of native resolution...

With AMD Catalyst Control Center I got this, maybe it can help. Not sure if Nvidia also has it with 3D.

This is because NVidia doesn't care about the issue. It's as simple as that, really. Pixel doubling is easy to do, but they opt not to.

With AMD it looks exactly as bad as with nvidia: a blur fest.

It's a question of the reconstruction filter, and for photos/video, something other than a box filter is usually closest to the source material. It'd be nice if they had a choice of filter, for when you really do want a box filter. See A pixel is not a little square (pdf).

is there a way to play fullscreen 720p without gpu upscale ?

Currently, I only know one way of doing that: GeDoSaTo (http://blog.metaclassofnil.com/?page_id=582). Only for DirectX 9 games, unfortunately.

Most important lines for what you want:

renderResolution 1280x720@60

presentWidth 2560
presentHeight 1440
presentHz 120 (or whatever Hz you want. Hz in renderResolution don't matter)
scalingType nearest (this is the most important step, because it will do exactly what you're asking for)


Then you have to select 1280x720 ingame.

I use Gedosato for Final Fantasy XIII pc , really works in upscaling the game to 1080p (from 720p) to get rid of the black bars.

I wish Gedosato would work for me for upscaling. It simply crashes both the games and Steam whenever I try and start a game. It only works with downscaling

still have to try Gedosato, by the way i have a really bad news, this PG278Q has an evident crosstalk in 3d, it's the third 3d monitor i get(samsung 2233rz-asusVG248Q), this one is the worst in 3d.
The old samsung had crosstalk on the upper side of the monitor, the asus VG248Q is simply perfect, this one has a much lower crosstalk compared t the upper side of my old samsung monitor , but is quite evident all over the monitor, it looks more or less like my samsung TV on the other room (series 6 46inches), maybe a bit more than my tv.
So basically in 3d is unusable, i'm going to move back to my VG248Q, i'll use this 27 on my mac just for work

Also this g-sync can't be used with anything else, i prefer much more using ulmb and 3d, and i don't like playing with low fps, so gsync is quite useless for me as the gain with high fps are minimal and it's preferrable to use ulmb instead.

so DON'T BUY ASUS PG278Q IF YOU PLAN TO PLAY GAMES WITH 3DVISION

i'm sure it's just a matter of sync the glasses pulse with the monitor but there's nothing we can do as the crappy NVIDIA never allowed us to tweak that pulse latency even if we have asked them a million times.
