D-Sub and HDMI connection for a 1920 x 1050 monitor; which one should I use?

Hey there,

I have an issue with my new LG E2251 monitor. It has HDMI and D-Sub connection ports, while my GTX 570 graphics card has HDMI and DVI-D connections. My 4-year-old monitor had a DVI-D connection so I was surprised not to find one in the monitor. For now, I connected the monitor with the D-Sub connection using a D-Sub-to-DVI-D adapter to connect it to the graphics card, and the image quality seems good enough (1920x1050 resolution).

Question is, will I get better quality and reliability if I just use a HDMI cable? I don't care about the fact that the HDMI can also carry sound signals, just the image/video quality. The user's guide of the monitor says I could possibly encounter "compatibility issues" while using the HDMI connection. I'm not sure.

Also, does anyone know why a brand-new monitor would not carry a DVI-D connection while an older one does? It seems counter-intuitive to me.

Thanks.

Thanks. So I will switch to the HDMI connection. I guess the compability issues may possibly be due to small scaling errors. I'll try and see.

It seems they didn't bother with a DVI connection while the HDMI would already provide digital input.

Now on a slightly unrelated note, when you say that it's pretty low-quality, I'm aware it's not really an expensive monitor, but does it being a budget monitor affect picture quality? I'm pretty much pleased with the resolution and the contrast ratio, which is comparable to Samsung monitors. So is it being "low-quality" due to it being less reliable over the long term, less durable, more power consumption etc ? Don't make me unhappy about my new monitor :D
