Your FPS has nothing to do with the Hz your monitor is displaying. FRAPS can only tell you how many FPS are being rendered, not shown on your screen.

Nothing has "no input lag". What you mean is the input lag doesn't bother you, or you can't notice it tongue.gif. Somebody else could be bothered though.

You don't need to scale native res. Therefore, it's perfectly possible for there to be a "no-scaler" option if nVidia wanted to allow it. The downside would be if you tried changing the res down in the game or the desktop, you would get a black screen.

How do you know if you're overclocked then?

You have tons of input lag because the setting "GPU - No Scaling" has drastically higher input lag than the setting "Display - No scaling" in Nvidia control panel. All you need to do is plug in a monitor that has a scaler so you can switch back and forth between those 2 modes to test it. If you can't notice a difference (the difference is huge and easily noticeable), then something may be wrong with your physical senses.

If you use a modified inf file to load an older driver such as 267.59 before the scaling module was rewritten, then you get to choose the regular "No scaling" option, which has much lower input lag and feels similar to the "Display - No Scaling" setting.

You didn't even attempt to test any of this and just put your fingers in your ears and said "blah blah blah I have no input lag".

I'm pretty sure the image would show up as either full screen or with black borders with scaling disabled completely in drivers. How else would you see a BIOS screen or dos prompt on a Crossover 27Q?

I don't see a reason they can't remove all scaling from drivers (unlike what they do now). They probably have some dependencies built into the scaling module for stupid bloatware apps like 3dvision and keep scaling intrusively activated 100% of the time in new drivers. Either that or it's just bad coding.

When I load into windows desktop the monitor displays my set refresh rate at 75 MHz on the screen. While playing a game it will display FPS upto 75-78FPS but if I set the refresh rate to 60mhz I will only see FPS of 60-62FPS. I know anything over the set refresh rate will not be seen. It was just a excercise to see if I could OC the monitor and see any benefit in games for example in skyrim without a ENB active I can leave off vsync and not have any screen tearing but with ENB enabled I get a better visual experience with refresh rate set at 60mhz and vsync enabled.

Any other thoughts/experiences with the text's sharpness/readability? I plan on using this monitor for web development.

I said to my eyes I have not input lag. Yes, but he is saying there is a option in the nvidia control panel for a built in scaler that the video board handles. I was under the assumption that the crossover did not have a scaler and it was managed by your video output device.

"much lower input lag and feels similar to the "Display - No Scaling" setting."

What hardware/chip is on the videoboard and or logic board that scales? Also how does the driver control it?

I'm not using GPU no scaling....I have had two 1080p monitors before this monitor and both had built in scalers. I do not notice any difference between any of the monitors I have used. I have had many people game with this monitor and they have never noticed it. Everything is smooth. You might have a different video board than mine or it may just be the model video card you have that doesn't handle scaling properly without input lag. Since you said scaling handled by the gpu gives you input lag but when there is a virtual option to select the display for scaling it does not.

There is *NO OTHER OPTION* if you plug a monitor with no hardware scaler into an Nvidia card using newer drivers. Of course you are using GPU scaling, it doesn't let you select anything else. Go to the Nvidia driver tab labeled "Adjust Desktop Size and Position" and look.

The setting "Display - No Scaling" basically bypasses the Nvidia scaling pipeline and defaults to whatever scaling solution your monitor has. Any of the "GPU scaling" choices adds like 1-2 frames input lag which the driver buffers, even while using native resolution. Using a setting like "Display - Aspect Ratio" for scaling also adds buffer lag while running native resolution too, but it's still less lag than any of the GPU scaling options.

Now do you understand???

Read the post I made describing the issue and showing pictures of it:

http://www.overclock.net/t/1355400/if-you-own-an-nvidia-card-and-buy-a-27-korean-ips-prepare-to-take-it-up-the-rear

This whole issue is also only a side issue of Nvidia input lag. The last completely lag free Nvidia driver was 186.82. Input lag started going up with the 190 series, and the only two drivers since then with low input lag like the old days are 267.59 and 295.73.

267.59 also lets you use the old scaling module, before it was rewritten, to bypass being forced to use GPU scaling on a Crossover.

Lots of other stuff covered in the link in my signature too.
