All PS2 games look really blurry on Panasonic Viera TV.
For comparison, when I play the Jak trilogy on PS5 (which is just the PS2 ports), it has a sharp and crisp image. But the same games on an actual PS2 are much lower quality. This leads me to think there's some scaling issue that the PS5 automatically fixes since I don't think they remastered it or anything. And the same applies to every PS2 game.
It's currently connected via RCA component cables, and I tried messing with the game mode settings on the TV but it didn't really do anything noticeable. I'm wondering if I should buy a PS2 to HDMI converter or if that might be even worse than the current set up. I don't have much money I can spend but if I need to I will, just whatever it takes to get it looking good. It looks like sh*
Not sure about your setup but just thought you should remember that the PS2 was primarily designed to be used with CRT TVs and they were blurry as hell. Game designers of that era expected it and even designed their in-game-assets around that e.g. jagged edges in low poly art got blurred into smooth curves.
PC emulators are even adding CRT filters to make games look more true to the intended vision.
Just want to add on clarification that this doesn't mean "they look bad because everything looked bad back then", but rather, they were designed to look good^1 on CRT displays because the graphics people were used to working with CRT artifacts, so when different display technologies arrived that didn't behave the same, the CRT-targeted graphics didn't look as good as they were meant to.
It basically came down to pixels bleeding into neighboring pixels in a way that created gradients between pixels. So while the pixels themselves were still limited to the ridiculously low resolutions of CRT TVs (which basically didn't change since broadcast TV was a thing), they could simulate a higher resolution for the shading with those subpixel gradients.
Though note that this "good" is still relative to how good things were able to look at the time. The resolution is still way under what you're used to today.
RCA cables, you mean the red, white, yellow composite cable?. It’s just an analogue signal over that yellow wire (red and white are audio).
The ps5 is doing a Full HD digital signal, surely.
Using a hdmi adapter won’t do anything, it’s not an upscaler. But it might introduce input lag.
If you want ps2 to look better, maybe try looking into Retrotink or something like that. I don’t know if it works with ps2 but it might be worth looking at My Life In Gaming videos about it to see how it works.
But for sure you’re not going to get a good signal from a composite cable.
Have a Retrotink 2x and can confirm that it works with the PS2, however the image quality improved dramatically when I switched from composite to component cables (still connected to the Retrotink). Don't expect any miracles, tho (it's SD after all).
