Am I reading that wrong, or would your display correct the lookup tables regardless of the device input. Meaning, wouldn't you need to use a monitor that doesn't do this internal correction to accurately measure the cards actual display output?
No, all the lookup tables to is translate a given input to a given output. They are three tables of numbers, with 8-bit inputs and 12-bit outputs. So it says "when you get a value of X for red, drive the subpixel with a value of Y."
Most monitors have them, it is how you adjust colour, contrast, and so on on them, the NECs are just able to be calibrated with their tools. Also the NEC's are higher bit, so they don't cause banding or colour loss.
However they are consistent in their operation on an input. So they operate the same on it, no matter what is feeding the signal, unless you change it.
The question isn't one of what the monitor is doing, the question is if given the same input in software from the two different cards, is that then passed along to the monitor unchanged? The best way to test that would be to record the DVI signal, but I don't have anything that can do DVI or HDMI in at 4:4:4, best I have does 4:2:2 which means it sub-samples colours making it worthless for a test.
Next best thing I could do was to measure the actual colour output. If the same input on both cards generates the same output on the display, then it is quite a reasonable assumption that it was the same signal being sent.
If anyone wants to buy me a Blackmagic DeckLink HD Extreme or an AJA Io XT, plus a stupidly fast SSD, I'll be happy to use them to do a direct signal capture.
if you know me then you know I personally prefer Nvidia but the ATI cards I used looked way better on my crt than any Nvidia card. it was the first thing I noticed and something I would have never expected at the time. in fact even last year when I used a couple of comps that had integrated AMD video they looked better than my gtx260 when using the crt. I dont see any difference when using an lcd though.
for the crt? yes. I was not aware that there was any other type of connection for a crt monitor.
I didn't forget anything. I am not even sure what is being described there is accurate or not. And it doesn't matter because from what I've seen, it is impossible to discern any difference between the two vendors, and I've seen both driving some expensive, high end displays. I personally have a fairly expensive plasma and I've driven it with both an Nvidia and AMD card, I didn't see any image fidelity differences at all, and honestly never thought about it.
Seems like the answer to a question no one asked? But some myths are hard to bust, to this day people are convinced that AMD/ATI drivers are on the same level they were in 12 years ago, but when it comes down to it, toss a coin there is no much to chose from.
