Issue with the graphics, please help

[Knjizevnik-frostmane]

Hello wonderful people, and sorry for the longer post.
I’ve had an issue with the screen that turned completely pink (screen was visible but it had sort of very strong pink filter that gave me headaches).
I started with changing the VGA cable, then the VGA to HDMI small adapter because graphic card has no VGA ports, only HDMI and DVI. Screen came back, but it was so like very rigid, hindered graphics, then I decided to swap my monitor completely and bought a 24 inch Dell LCD with 75Hz refresh rate and proper HDMI connection.
Screen is okay now, but I still have this weird feeling of everything being kinda pixilated, not sharp enough, not clear enough, as if I used some super small resolution and had everything magnified under zoom tool.

My current setup is:
CPU: Intel Core i5 4460 @3.2 Ghz
Motherboard: Gigabyte B85M-D2V
RAM : 2 x 8GB DDR3 1600 Mhz
Graphic card: Nvidia Geforce GTX 750 Ti 2GB DDR5

I know it is not the latest machine, I am not a competitive gamer, I don’t raid, however I used to have a solid 70 FPS with video quality 9/10 in game (and that was with 8GB less of RAM).
Now with new 75Hz monitor and more 8GB of RAM,I am sitting with 40 FPS outdoor world and 9/10 quality.

Please recommend me what to do (from playing with resolutions, in game settings, and literally anything else).
Is there a way to test the graphic card, to see has it gone wrong?
It is not only the WoW game, even when I play League of Legends, I still have this funny, not sharp looking enough feeling, and that game can be ran even on smartphones.

Thank you all
Cheers

the performance drop is most likely explained by your old vga monitor running at a lower resolution, while the new one runs at a higher one. increasing resolution is very taxing on the graphics card.

ram quantity isn’t really directly related to game performance. it’s more like it doesn’t matter until you hit the limit, at which point it becomes a disaster.

as for this fuzziness, perhaps you’re not running at the native resolution of the display? or perhaps you’re using some kind of resolution scale/render scale?

Yeah, that’s what im thinking too. Maybe his old display was “hd ready” (720P maybe) and not full HD (1080P).
The new Monitor is 1080P or higher?
Anyways you got to check what resolution your new one has and then change it in the settings of your games.
Then your image should be sharp again, but like mentioned above, you will lose FPS because higher resolutions are more taxing on the GPU (and your 750ti is very slow now).
