This test means nothing. It should had made with a statistician, the same way that a motherboard review is done by somebody knowledgeable in motherboards.
48 samples is too low. If you generate 48 samples randomly, most results will look like this, instead of 50% / 50%
Start excel, generate 1000 samples at random, and it will come close to 50% for each choice (example: 55/45%). But if you generate only 48, most trials will be extremely biased in favor of any alternative.
In other words, this test is not different than a random result. It means nothing. You can repeat exactly the same experiment and get the opposite results.
Worse, if 10 out of 50 players (20%) know what is the real hardware, then it gets even more biased.
Of course, you cannot collect 1000 monitors, but you can cycle the players, and get more players.
