Questions about ASUS ROG Strix XG32UQ

Hello, I have the following problem When gaming, I have a black screen for 1 second in some games, 4k 160 heart set on the monitor g-synch active. But if i switch off the overclocking of the monitor and it runs with max.144 heart i don't have this problem,or if i deactivate g synch everything is ok. As I said, the problem only occurs with some games. Display port cable has already been replaced, graphics card drivers up to date.

How many kilos does the monitor weigh without the stand? Does anyone know?

I bought this monitor and realised that not all the specifications are correct. chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://dlcdnets.asus.com/pub/ASUS/LCD%20Monitors/XG32UQ/ASUS_XG32UQ_German.pdf?model=XG32UQ On the Asus website you can find out with a difficult search that the monitor has a colour depth of 8 bits. Under the advanced display you can also see that the monitor actually only has 8 bits. Now I'm wondering who wrote these specifications. I was looking forward to a true colour picture. I think it would be a pity if you could just give wrong specifications without seeing any consequences.

I want to buy the ASUS monitor - ROG Strix XG32UQ, now I see it has a DP 1.4 is it compatible with the graphics card Gigabyte GeForce RTX4090 AERO OC because it has a DP 1.4a ?

Does the monitor automatically change the input source when activated?

Is it possible to mount the screen on an Icy Box IB-MS314-T monitor mount?

Is the product completely new and delivered with a previously not-opened package?
