Overclocking and forcing resolution on 29 inch LG Ultrawide monitor

[schmidtb26]

My set up is i7 6700k
asus strix OC gtx 1080
16gb ddr4 2400mhz

I currently have a 29 inch LG ultrawide 2560x1080p monitor. 60 hz.
It is currently overclocked to 75hz(also through nvidia control panel) refresh and I have been running at that refresh basically since I got the monitor.


I only recently realized I can change the resolution to 3440x1440p resolution. It is not the monitors native resolution but seems to easily accept the change through Nvidia control panel. Supported games such as the Witcher 3 and PUBG both play the game wonderfully at this resolution and with a good Overclock my card can maintain my 75hz refresh rate on both of these titles and a few others I have tried at that resolution.

That being said, is forcing the monitor or my GPU to render the display at a non-native resolution an issue? Can this damage either the monitor or my GPU over time or the fact that my card can handle that resolution not make it an issue? Please advise....Its very nice having the extra pixels but if its at the expense of the life of my hardware I would just as easily revert it back to 2560x1080.

You cant run 3440x1440 on a 2560x1080 monitor, that doesn't make sense your monitor cant just spawn more pixels because you tell it to. I would assume you are using something like nvidia DSR which allows the game to render at a higher resolution which can make textures look a bit more crisp I personally dont like because it seems to blur the image a bit unless you have DSR smoothness set just right for your game. What is the model number of your monitor?

They are both 21:9 ratio so there is no issues with image being stretched or anything. I am sure it has more pixels or is at least straining my GPU more because while running 2 separate frame rate monitoring programs they both show about a 10+ fps decrease when I "upscale" the resolution and play either the witcher 3 or PUBG.

To me the picture looks crisper and slightly smaller but much more detailed. A side by side and clearly when its at 3440x1440 is the better picture. IF my FPS didnt drop when changing I wouldn't think it was working either but because of the improved visuals and framerate drop I am convinced I am running at a higher resolution.

its an LG 29UM68-P IPS LED w/ Freesynch

Like Dunlop said, that monitor is a 2560x1080 monitor and you can't run it in 3440x1440 mode UNLESS it's the DSR technology on nVidia cards. In that case there is no harm to your monitor, just a performance hit. The monitor is still doing 2560x1080.

The monitor does not have more pixels than 2560x1080 that is a physical thing, you can take a magnifying glass and count the individual pixels no software can make your monitor grow more pixels that's impossible. Yes of course framerate will drop, with DSR set to 3440x1440 your gpu is rendering the game at 3440x1440 then fitting it to your 2560x1080 monitor.

You know how consoles games will often run at say 900p but they fit perfectly to 1080p screen? You are basically doing the opposite of that.

So I am upscaling and there shouldnt be any adverse effects ? To me its an improvement, visually, compared to running the monitor in native resolution.
