Just tried to OC my Samy S23 750D to 120hz with HDMI and it seems to work

post #1 of 7
Thread Starter 
Has anyone with this monitor ever tired to do this? I OC'd it in Nvidia control panel and tried it first at 75 and 100hz and then 120 and it said that the test was successful, but does anyone know if there is another test to run to make sure it is working properly besides a game? The only reason I even tried this is so I could run all three of my monitors since I was running the 750D off the only DP connection on the card and my Apple Cinema display only has a mini dp cable.

Yes sir there is two ways that you can test the monitor.
first try the refresh rate multitool here

Second use powerstrip and run the lines detector

Both are nice and free but do NOT stare at the refresh rate tool (blinking white and black bars FAST)
Also readings will not be accurate unless your overclocked monitor is the only one active at the time.

Just used the refresh rate tool and it did show 120hz with all the other monitors unplugged, so I guess it works! I did not think it would.

It's my understanding this only works with a direct HDMI to HDMI connection.

(i.e. Don't use a DVI to HDMI adaptor; because that's single link.)

Theoretically... I suppose if one had a single link DVI port, one *might* be able to force the graphics card to violate the DVI spec and output a greater than 165mhz pixel clock signal via single link DVI.

The reverse has already been demonstrated to be possible (HDMI source to a DVI sink, operating at >165mhz SL-DVI). However, that doesn't violate any specs on the source side, whereas the sink, a Catleap 2B, is known not to be limited by the DVI spec.

I knew that would be a problem from everything I read just like going from DVI to DP is an issue as well. That did not work at all for me.
