Q10 Pro is a quite expensive (and also quite pointless) choice for a CRT TV for sure...
The best advice I can give is to switch to at least a FHD LED TV, if you choose the model with caution, you won't ever regret it.
But: Maybe there's some tricking with the colorspace settings that could help. Not sure, I'm not familiar with CRT's. Check Settings->More->Display and so on...
