1280x720 75Hz not filling in the whole screen

[Gabriel Goldberg]

Hello, my name is Gabriel.


Recently I found out the resolutions my monitor can support 75Hz on, and the only one I want to use is 1280x720. Generally I would use 1280x720 60Hz, (instead of 1080p because it is a bit laggy in games) but I realized I can use 75Hz to make it look way smoother. The only problem is, whenever I use 75Hz as an option, it makes my screen get big black bars surrounding it. When I use 60Hz, it's fine and has no black lines/bars. Is there anyway I can get rid of the black bars when using 75Hz? Thank you!

Oh, integrated video. I think that is a function of the iGPU. The vertical refresh rate of the iGPU may only be 60Hz native.
What told you the refresh rate was 75Hz? And was that the monitor or the iGPU that was 75Hz capable?

 

[Gabriel Goldberg]

I believe the GPU was 75Hz; because on my desktop I right clicked and went to graphics properties and the refresh rate was at 60 so I clicked it and saw 75

Yeah, I'm pretty sure the Intel HD Graphics 4600 is limited to 60Hz vertical refresh rate. You probably saw the monitor's refresh rate and when switching to 75 Hz, the iGPU had to "adapt" to something it can't produce. The result is a smaller display with fewer pixels to render per frame. Hence the better fps performance resulting in smoother graphics.

So it is not possible to fix, correct? Thank you, also

If there is, it is beyond my knowledge. Does your Intel Graphics Properties offer any option for that?

No, but thanks!

I wouldn't get too concerned over the 60Hz vs 75Hz. The BenQ RL2455HM is only a 60 Hz vertical refresh panel anyway if this is your monitor: http://www.engadget.com/2013/01/10/benqs-rl2455hm-gaming-monitor-cranks-up-response-time-to-1ms/
So you may have only been imagining you were seeing a difference.

Ah, okay. Thanks for your help.
