1366*768 HDMI vs 1366*768 VGA

[G9xftw]

I have noticed great difference in the FPS count between two monitors connected to my GPU (hd7950). In HDMI mode on tv1 with GTA V on ultra I get like 24-35 fps. But with same resolution setting on VGA I get 40-50 fps. Is the HDMI medium simply more taxing? or are the cables to blame? VGA cable is the one which came with the acer monitor. HDMI cable is genuine one from SONY.

I can not exactly pinpoint what is happening in your rig but cables do NOT tax the system . DVI is pretty much equal to HDMI but without audio if I am not wrong. Regardless, your connection doesn't affect your FPS.

unless its running the HDMI at a higher resolution than the VGA, there should be no difference in frame rate.

be sure that the HDMI and VGA connections are both running at the same resolution in your testing.

HDMI is a lot clearer, as it is a digital signal. it should look much better in HDMI, despite the framerate.

The HDMI monitor itslef does a max resolution of 1366*768, not a full HD monitor. The VGA monitor also the same resoultion. I believe both cables are good quality. Recently PC mag came with an article on overclocking your monitor. And they mentioned cable quality can be a factor to help boost maximum refresh rate....anyways. I did not have the audio play through HDMI, I have 2.1 setup connected directly to my rig.

I also double checked, the game settings were same for both tests too.

The HDMI monitor is 24inches and the VGA mointor is 18.5 inches. Could that be the cause? bigger mointor=more pixels and thus more GPU processing thus lower fps and vice versa?

that article was about running cables out of spec (1366x768 is well within spec). within spec all cables should perform the same. also, the physical refresh rate of the display and interlinking of that to the GPU has no influence over the rendering capabilities of the GPU. if this is not how your hardware is performing, then you have either misconfigured something, or have malfunctioning drivers/hardware. (of which, all i can do is recommend trying different driver versions and hardware)

i am sorry i am of no further help and good luck with finding a solution.

No, its still the same amount of pixels, thats what the resolution is. 1366x768 = 1,049,088 pixels, doesn't matter what the monitor size is.

you're sure you're running at the same resolutions?

Yes. I am certain the settings are same when using both screens. The bigger SAMSUNG screen gives a huge dip in fps.
